Foreword 1

The pace of cyber threat evolution is relentless. As enterprises shift into cloud, hybrid, and zero trust architectures, the demand for cyber defenders—especially those designing and engineering secure environments—has risen exponentially. To meet this challenge, organizations need leaders who not only grasp technical nuances but also understand risk, compliance, governance, and resilient design at scale. This is where SecurityX, CompTIA’s advanced, expert-level cybersecurity certification, comes in.

As former director of cybersecurity products at CompTIA, I’ve witnessed firsthand the rising complexity of enterprise security. When CompTIA launched the original certification, CASP+, over a decade ago, the goal was clear: validate the hands-on capabilities of senior security professionals. But as attackers and technology matured, so did the skillsets needed for defense. That’s why CASP+ evolved into CompTIA SecurityX—a rebranded certification to emphasize advanced skills within CompTIA’s portfolio.

What defines success in this field? A security architect—one of the primary roles SecurityX targets—must have the vision to embed security in business strategy, design resilient systems, collaborate across stakeholders, and implement controls that both enable and protect. Similarly, a senior security engineer must operate efficiently and tactically: configuring endpoint and cloud security, cryptography, threat detection, and incident response across environments. The SecurityX exam doesn’t treat these roles as academic. Rather, it tests your mettle through performance-based questions that reflect real enterprise scenarios and involve applied knowledge.

Although the exam structure retains performance-based and multiple choice questions, the SecurityX revision removed outdated objectives and added focus on modern security priorities such as zero trust, SASE, cloud-native controls, threat hunting, AI considerations, and streamlined GRC practices.

As a credential, SecurityX aligns with critical frameworks and standards, such as ISO/ANSI 17024 accreditation and Department of Defense Directive 8140 (formerly 8570), and has global recognition across industries such as finance, healthcare, and government. It validates mastery of architecting secure solutions across cloud, hybrid, and on prem environments, embedding governance, risk management, cryptography, automation, monitoring, and incident response in one integrated profile.

Why write this book now?

Because enterprise security remains one step behind innovation. As more organizations adopt zero-trust, micro-segmentation, DevSecOps, and AI-driven defenses, the stakes have never been higher. Many CISOs report difficulty in hiring and retaining skilled senior security engineers and security architects. SecurityX was created to define, validate, and accelerate professionals into these roles. However, attaining the SecurityX certification alone is not enough.

This book is a unified reference companion for both preparation for the exam and ongoing practice. You’ll find detailed explorations of domain concepts, real-case scenarios, risk frameworks, cloud control strategies, detection pipelines, engineering workflows, and governance structures. Think of it as both a preparatory guide and a handbook to strategic implementation in wide-scale environments.

As cybersecurity evolves, so must our tools. I believe SecurityX marks a turning point: a shift from checklist compliance to adaptive, resilient enterprise defense. It rewards seasoned professionals who can think like architects and act like engineers.

Whether you’re reading this as a candidate preparing for the exam, a mentor shaping emerging talent, or a leader solidifying your team’s capabilities, may this book enable deeper insight and greater confidence.

Here’s to the next generation of cybersecurity architects and engineers!

Foreword 2

From the early days of IT operations and the help desk, certification in both IT and security essentials has been the hallmark of any technical career. From U.S. Department of Defense certification requirements, such as the original 8570, through CISSP and IT certifications for vendor-specific products, whether coming from a technical background or making a transition into cybersecurity, certifications can provide the foundational knowledge and fundamental experience to build a comprehensive skill bank. But cyber leaders need deep and broad knowledge across the cybersecurity domain to truly be effective.

When I started on the help desk over 17 years ago, we had limited options for advanced-level certification paths outside of vendor-specific or relatively broad security topics. Through my years in IT operations, development, and security, I have learned one fundamental thing: the basics of security carry through every technical path. However, when considering a leadership position in cybersecurity, more advanced certifications are required. As SANS Practitioner of the Year, and now a senior technical staff member and senior manager for artificial intelligence and platform development at IBM, I have shifted focus from focused topics to deep learning across multiple domains.

When I made the transition from IT and development into cybersecurity, there were some serious fundamentals that carried me into becoming a security engineer, and ultimately, a senior security architect. Understanding threat modeling, using frameworks such as MITRE ATT&CK, understanding OWASP Top 10 lists, and other resources such as STRIDE and TAXII, gave me a leg up on building a deep knowledge of cybersecurity. Each of these components is covered in great detail, enough to not only review and understand deep technical topics in your professional career but also study for the SecurityX exam as well.

Any great advanced-level certification guide will include deep learning and advanced topics across the cybersecurity domains. This guide does exactly that. In addition to comprehensive content, it offers essential tools such as practice questions, flashcards, and mock exams to help you assess your knowledge and prepare effectively. Since the material in this book covers a broad range of security and technical topics, it can be used as a thorough guide for security people, processes, and technology in complex ecosystems. These competencies will aid new cybersecurity professionals, as well as help leaders brush up on the modern foundational components of cybersecurity.

The threats our organizations face are real. Emerging technology only compounds those threats. Use this guide not just as a checklist for exam prep, but also as an applied framework for decision-making for security operations center managers, security engineers, and architects. Good luck, and welcome to the modern education and certification paths for cybersecurity leaders.

Given a Set of Organizational Security Requirements, Implement the Appropriate Governance Components

Organizations face many security threats that can compromise their critical assets, disrupt operations, and damage their reputation. To effectively manage these risks, it is essential to implement robust governance components that align with organizational security requirements. Governance in cybersecurity refers to the frameworks, policies, processes, and tools that ensure an organization’s security practices are well-structured, consistent, and aligned with business objectives.

The ability to implement appropriate governance components is crucial for ensuring that security measures are not only effective but also sustainable and scalable as the organization grows. Without proper governance, security efforts can become disjointed, leading to vulnerabilities, inefficiencies, and non-compliance with legal and regulatory requirements. In addition, strong governance provides a clear structure for decision-making, accountability, and continuous improvement in security practices.

This skill involves understanding and applying various governance elements to create a cohesive security program that supports the organization’s goals. It includes developing and maintaining security program documentation, managing security initiatives, utilizing governance frameworks, overseeing change and configuration management, leveraging governance, risk, and compliance (GRC) tools, and ensuring data governance in staging environments.

In this chapter, we will focus on Domain 1:Governance, Risk, and Compliance, covering Objective 1.1,Given a set of organizational security requirements, implement the appropriate governance components. The following exam topics will be covered:

Security program documentation Security program management Governance frameworks Change/configuration managementGRC tools Data governance in staging environments

Security program documentation

Security program documentation is foundational to an organization’s security governance. It provides the necessary guidelines, standards, and procedures that govern security practices within the organization. Many compliance programs require documented evidence that key security policies are being actively implemented within an organization. In this section, we will explore what should be included in good documentation.

Policies

The most effective way to ensure cybersecurity is to establish and enforce it through a formal written security policy document. For instance, a policy might mandate the use of multifactor authentication (MFA) for accessing critical systems, ensuring that unauthorized users cannot easily gain access. Without a policy document, the use of MFA might be considered a good idea, but it is less likely to be enforced, and there could be a lack of clarity under which circumstances MFA is required. An organization’s information security policy outlines the acceptable use of IT resources, data protection measures, and the roles and responsibilities of employees. For instance, it might state that employees can only use company-provided devices (laptops, phones, etc.) for work-related tasks or that it’s the HR department’s responsibility to ensure new staff receive cybersecurity training.

Policy documents within an organization are typically stored in a secure and centralized location to ensure accessibility, version control, and compliance. Document management systems (DMSs) such as SharePoint, OpenText, and Documentum are designed for storing, managing, and tracking electronic documents and allow for secure access control, version tracking, and compliance with retention policies. They are often used by organizations to enforce strict governance and auditing requirements for critical policy documents.

Procedures

While policies tell people in an organization what they should do, they also need to know how to do it. Procedures ensure that the appropriate steps are taken when following a policy. For example, if a security breach occurs, the incident response procedure details the steps employees must follow to contain, mitigate, and report the incident. This might include actions such as disconnecting compromised systems from the network and notifying the security team immediately.

Standards

Many cybersecurity best practices can be applied across various industries, and several industry standards help organizations understand and benchmark their security practices.

For example, an organization may adopt the ISO/IEC 27001 standard, which provides a framework for establishing, implementing, maintaining, and continually improving an information security management system (ISMS). This helps ensure that security measures are consistent and meet international best practices. In some jurisdictions, certain industries are legally mandated to follow certain security standards. For instance, in the US, companies that process credit card data must follow the Payment Card Industry Data Security Standard (PCI DSS).

Guidelines

Guidelines assist in interpreting a policy. Password creation guidelines might recommend using a mix of upper and lowercase letters, numbers, and special characters. They may also suggest avoiding the reuse of passwords across multiple systems.

Policies, procedures, standards, and guidelines all offer a framework for robust security in your organization. However, if members of staff are not aware of them, don’t understand them, or tend to ignore them, the framework isn’t much use. To implement your organization’s best practices, you need a security program, something we’ll discuss next.

Security program management

A company’s security program outlines the overall approach to ensuring security is derived from policies and specifies the implementation required to ensure compliance with security regulations. It provides a structured approach to safeguarding an organization’s assets, data, and operations.

For security programs to be effective, they require strategic planning, implementation, and continuous oversight. If a security program does not align with a company’s business objectives, it can lose management support, slow down operations if controls are too restrictive, increase exposure to cyber risks if controls are poorly implemented, and even lead to compliance violations if mandated standards are not followed. Effective security program management mitigates these issues by ensuring buy-in from management, continuously monitoring for new risks or regulatory changes, and providing training to ensure everyone understands their role in cybersecurity.

Ultimately, a well-managed security program protects the organization from potential threats, minimizes the impact of incidents, and builds trust with stakeholders. Effective security program management ensures that security initiatives are not only implemented but also maintained and continuously improved.

This section will cover awareness and training, communication, reporting, management commitment, and the Responsible, Accountable, Consulted, and Informed (RACI) matrix.

Awareness and training

As a cybersecurity professional, you must be vigilant of and keep up to date with the most common cybersecurity threats. Despite most people in large organizations not being cybersecurity professionals, they have constant access to your IT network and the valuable resources in it. One crucial aspect of a cybersecurity program is ensuring that people are aware of the threats out there, how to recognize them, and what to do when they come across them.

When training staff, it is important to focus on common cybersecurity threats while also highlighting threats that may be unique to the organization’s operating environment. The main areas to focus on are social engineering (phishing in particular), privacy, the security of data, operational security (OPSEC), and situational awareness. This section will look at these in detail.

Employees should participate in regular interactive security training and awareness programs that focus on identifying and reporting phishing attempts. One key element is a simulation in which employees receive simulated phishing emails that mimic real-world tactics. After each simulation, a debriefing session is held that highlights indicators of phishing, such as mismatched URLs, unusual requests, or typos, and teaches the appropriate reporting protocol.

Over time, this approach improves vigilance and reinforces the habit of scrutinizing unsolicited emails, links, and attachments.

Security training sessions on the importance of data encryption, secure communication, and safe browsing practices can help reinforce a security-conscious culture.

Regular training sessions can include in-depth tutorials on data encryption techniques, secure communication protocols, and safe browsing practices. For instance, employees can be introduced to real-world examples of data breaches caused by poor encryption or unsecure communications. A hands-on approach can involve showing employees how to verify SSL certificates in browsers, use VPNs for secure remote access, and recognize phishing websites by observing URL structures. Additionally, testing knowledge through quizzes or simulated scenarios can help with measuring understanding and retention.

When conducting awareness and training sessions on social engineering, use real-world examples. One such example is an internal staff member posing as an attacker, who might call employees claiming to be from IT support and request login credentials or access to secure areas. After the exercise, trainers should discuss the red flags that employees should have noticed, such as a lack of proper identification or the use of pressure tactics. This experiential approach leaves a lasting impact by putting employees in realistic situations where they must rely on their training while emphasizing the importance of verifying data.

Some employees might need specialized training sessions on privacy laws such as the General Data Protection Regulation (GDPR), especially if they handle sensitive personal data regularly. This training should include case studies of privacy violations and the resulting legal consequences for both individuals and organizations. Employees can be given practical examples of how to handle personal data responsibly, such as anonymizing datasets, securing physical files, and understanding the importance of consent when collecting personal information. Regular assessments, such as scenario-based quizzes, can help reinforce this knowledge.

OPSEC is a proactive cybersecurity discipline that focuses on identifying, protecting, and managing sensitive information and operational processes to prevent adversaries from exploiting vulnerabilities. Employees should be encouraged to be aware of OPSEC and learn to protect confidential, restricted, or sensitive information in their daily activities. This may include payroll records, insurance policy details, or trade secrets and proprietary algorithms. Training sessions on OPSEC should focus on embedding good practices in daily routines. This could involve creating realistic scenarios that illustrate common lapses, such as an employee discussing confidential matters on a mobile phone in a public place or sharing business details on social media.

Employees should be provided with clear guidelines on how to protect sensitive information outside the office, including using privacy screens in public places, employing encrypted communication channels, and never leaving confidential documents unattended.

Situational awareness, or being aware of your surroundings and potential threats, can help employees prevent security incidents. Employees can be trained through workshops and activities that improve their observation and awareness skills. For example, simulated environments can be set up where employees must identify and report anomalies, such as an unlocked workstation, an unattended ID badge, or a visitor without an escort. Employees can also be shown examples of suspicious activities, such as tailgating (unauthorized individuals following them through secure doors), and should be encouraged to report anything unusual using predefined reporting channels. Reinforcing a culture where employees are rewarded for vigilance and proactive reporting can further instill situational awareness.

Communication

Effective security program management governance requires a structured communication plan to ensure that security policies, risks, incidents, and compliance requirements are clearly conveyed to all stakeholders. Communication should be tailored to different audiences—executives need high-level risk reports, IT teams require technical threat intelligence, and employees benefit from security awareness training. Key security messages should cover policy updates, compliance mandates, incident response protocols, and emerging threats, all delivered through appropriate channels such as email, dashboards, real-time alerts, and training platforms.

A regular communication schedule should include weekly threat updates, monthly training, quarterly executive briefings, and annual incident response drills to maintain security awareness. Organizations must also establish feedback mechanisms such as anonymous reporting channels and security culture surveys to encourage engagement. Ensuring compliance requires gathering audit trails of policy acknowledgments, incident communications, and training completion records.

Reporting

When it comes to security, certain information should be readily available to the relevant stakeholders within an organization. Regular security reports must be generated to provide management with insights into current threats, incidents, and the effectiveness of security measures.

For instance, a monthly report might include metrics on the number of phishing attempts blocked by email filters. Reports are typically provided by different teams and roles within the organization, depending on the audience and the type of security reporting required. Examples of the entities responsible for reporting, and what they are tasked with reporting, include leadership, the security operations center (SOC) team, risk and compliance teams, infrastructure teams and GRC platforms, and automated tools. Table 1.1 shows the typical responsibilities for each entity:

Table 1.1: Typical reporting responsibilities

These reports are consolidated and tailored for different stakeholders to ensure informed decision-making and continuous security improvements.

Management commitment

To ensure a good security posture throughout an organization, senior stakeholders must be fully committed. Senior management demonstrates its commitment to security by allocating a budget for security initiatives, participating in security awareness programs, and endorsing security policies. Senior management and board members are responsible for ensuring the company complies with relevant regulations. If a company is not compliant, it can face a variety of negative outcomes that can significantly impact its reputation, operations, financial stability, and legal standing. A regulator, such as GDPR, can inflict significant financial penalties for non-compliance. Companies can also face criminal charges if non-compliance is due to deliberate negligence or even fraudulent activity.

The RACI matrix

For a security program to work properly, it needs to be clear who does what. If responsibilities aren’t outlined clearly, it is difficult to hold departments or individuals accountable. Tasks can be duplicated or overlooked, which can result in miscommunication, bottlenecks, and lost information.

Using a RACI matrix, you can clarify roles and responsibilities for various tasks, processes, or deliverables, as well as ensure clear lines of communication. Let’s take a closer look at what RACI stands for:

Responsible (R): The person(s) responsible for executing the task or process. This individual or group does the work to complete the task. In a security management program, this would be assigned to the security and IT teams.Accountable (A): The person who is ultimately accountable for the task’s completion and has the authority to make decisions. There should be only one accountable person per task. This may be assigned to the chief information security officer (CISO) or compliance officer.Consulted (C): The person(s) who provides input, feedback, or advice on the task. These individuals are usually subject matter experts or stakeholders whose opinions are sought before a decision is made. The IT team or compliance officer might be consulted to ensure that the security program meets the organization’s security standards.Informed (I): The person(s) who are kept informed about the progress or outcomes of the task. They do not contribute directly, but they need to be aware of developments. In this case, the executive leadership and board members would need to be informed as they carry ultimate responsibility for security governance.

By assigning specific roles to individuals or groups, the RACI matrix eliminates confusion about who is responsible for what, ensuring that tasks are completed efficiently. It helps ensure that everyone involved in a project or process knows who to contact for information, approvals, or support. By clearly defining who is accountable for each task, the RACI matrix ensures that there is a single point of responsibility, reducing the risk of tasks being overlooked or neglected. Knowing who needs to be consulted or informed helps streamline the decision-making process, avoiding delays and miscommunications.

To create your own RACI matrix, you will need to follow these steps:

Identify tasks/processes: List all the tasks, processes, or deliverables that need to be managed.Identify roles: List all the roles or individuals involved in the tasks.Assign RACI: For every task, designate individuals who will be Responsible, Accountable, Consulted, and Informed.Review and validate: Ensure that the matrix is balanced (so that each task has one person accountable, and responsibilities are not overloaded) and that all stakeholders agree with their roles.

Table 1.2 is an example of a RACI matrix, with tasks down the left-hand side and the stakeholders at the top. The stakeholders are the CISO, the SOC team (SOC), the IT team (IT), the compliance officer (CO), and executive leadership (EL):

Table 1.2: Example of a RACI matrix

As you can see, by using a RACI matrix, your organization can manage responsibilities, reduce confusion, and ensure smooth project execution effectively.

Along with training and awareness, effective communication and reporting strategies, and management buy-in, the RACI matrix can be an important part of your security program management. An effective security posture is also a complex one, so it is advisable to structure it well.

However, you do not need to reinvent the wheel every time you are designing security governance systems. There are tried and tested governance frameworks that can help you implement and ensure robust security guidelines that align with your business objectives. We’ll look at these in the next section.

Next, we’ll discuss how to manage governance for your organization.

Governance frameworks

Governance frameworks provide structured approaches to managing IT and security within your organization while still aligning with business goals. Frameworks such as Control Objectives for Information and Related Technologies (COBIT) and Information Technology Infrastructure Library (ITIL) set out best practices in industry compliance and risk management while helping you map the goals of your business to the goals of your IT structure. For example, a governance framework may offer the right evaluation process to ensure that security governance in IT matches the company’s regulatory requirements. In essence, IT and security function as strategic enablers rather than obstacles, ensuring they drive business success rather than hinder it.

The next section will cover COBIT and ITIL in more depth.

COBIT

COBIT was created by the Information Systems Audit and Control Association (ISACA) and, as mentioned previously, is a globally recognized framework for IT governance and management.

Note

At the time of writing, COBIT is in version 2019.

Along with a management framework, COBIT also includes detailed descriptions of the IT processes necessary to manage and control information systems. These processes cover areas such as planning, building, running, and monitoring IT systems.

Central to COBIT are control objectives (the CO part of COBIT). Each control object is a statement, such as manage risk, which relates to a specific goal. There are 40 such objectives, divided into 5 domains. The five control objectives are as follows:

Evaluate, Direct, and Monitor (EDM): This focuses on the governance responsibilities of overseeing IT performance. It involves evaluating risks, directing IT initiatives, and monitoring compliance and performance. Objectives include ensuring stakeholder engagement and the delivery of benefits.

Align, Plan, and Organize (APO): This deals with planning and organizing IT resources and covers activities such as IT budgeting, resource allocation, risk management, vendor management, quality management, and security management.

Build, Acquire, and Implement (BAI): This focuses on the development and acquisition of IT solutions. It ensures that new projects and services are delivered on time and within budget and meet the required quality and performance standards. This domain covers system development, change management, and implementation practices.

Deliver, Service, and Support (DSS): This emphasizes the operational aspects of IT, including the delivery of IT services, incident management, security management, and continuity planning. It ensures that IT services are delivered effectively and securely, meeting user needs and maintaining operational stability.

Monitor, Evaluate, and Assess (MEA): This involves ongoing monitoring and assessing IT processes to ensure performance, compliance, and alignment with business goals. This domain focuses on performance monitoring, internal audits, and compliance checks to assess the effectiveness of IT governance and controls.

These processes are then divided into further sub-processes, detailing each activity. For example, Manage risk is the twelfth control objective of the APO domain, so it is known as APO12.

The control objective is then broken down into sub-processes, as shown in Table 1.3:

COBIT 5 Process Reference

Process Name

APO12.01

Collect data

APO12.02

Analyze risk

APO12.03

Maintain risk profile

APO12.04

Define a risk management action portfolio

APO12.05

Respond to risk

APO12.06

Articulate risk

Table 1.3: Breakdown of COBIT APO12

COBIT’s management guidelines help break down how to implement these control objectives by using a RACI matrix, establishing processes, and using performance indicators to measure outcomes. For example, with APO12, a key performance indicator (KPI) might measure risk reduction effectiveness.

Finally, COBIT’s maturity models allow organizations to assess the maturity and capability of their IT processes to identify areas for improvement and benchmark against industry standards. For example, a process capability model evaluates each IT process against a six-level (0-5) capability scale. Level 0, the lowest, is incomplete, whereas level 5, the highest, is optimized. Figure 1.1 shows an example of COBIT’s Maturity Model for APO12.05, Respond to risk:

Figure 1.1: COBIT’s maturity model

Figure 1.1 shows how the response to risk matures in measurable stages. These stages are as follows:

Non-existent: No formal risk response process exists.Initial/ad hoc: Risk response is unpredictable and undocumented. Repeatable but informal: Basic risk response processes exist but lack consistency.Defined process: Formal policies and structured risk processes are in place.Managed and measurable: Risk response is monitored, measured, and continually improved.Optimized: Risk response processes are fully integrated, proactive, and automated.

Note

A bank can use COBIT to align its IT governance and risk management practices with banking regulations such as Basel III, GDPR, PCI DSS, SOX, and Federal Financial Institutions Examination Council (FFIEC) guidelines. COBIT provides a structured framework to ensure compliance, enhance security, and mitigate risks:

EDM: The board of directors sets policies for data privacy (GDPR) and fraud prevention, which ensures IT governance aligns with business goals and regulatory requirements. APO: The bank develops a risk assessment framework to meet Basel III requirements. This helps to establish risk management, security policies, and regulatory strategies. BAI: A new online banking system undergoes security audits and compliance checks before launch. This ensures secure system implementation and compliance during IT deployments.DSS: The bank monitors cybersecurity threats, ensuring compliance with PCI DSS for credit card transactions. This helps with managing incident response, cybersecurity, and fraud prevention.MEA: The bank conducts quarterly IT audits to verify compliance with financial regulations. This enables internal audits, continuous monitoring, and regulatory reporting.

At all stages, progress is measured quantitatively against a process capability model, with responsibilities made clear. Once the maturity is at a high level, the bank will have achieved great customer trust, thereby aligning with the IT goals of data security.

ITIL

Whereas COBIT is useful for organizations that need to establish IT governance, risk management, and strategic alignment, ITIL is more focused on optimizing IT service delivery day to day. It focuses on managing the entire life cycle of IT services, from design and development to delivery and support. The goal is to ensure that IT services meet the needs of the business and provide value to customers. For example, a company may use ITIL to manage its helpdesk services, ensuring that users can quickly resolve technical issues and receive consistent support.

ITIL is structured around a service life cycle, which is divided into five key stages:

Service strategy: This stage focuses on defining the strategy for IT services. It involves understanding the needs of the business, determining what services are needed, and developing a service portfolio. This might be used when deciding whether to offer a cloud-based service to customers and determining how it aligns with the organization’s long-term goals.Service design: This involves designing new IT services or modifying existing ones to meet the strategic objectives defined in the service strategy stage. It includes designing architecture, processes, policies, and documentation. An example of this is designing a new email service, including capacity planning, security requirements, and user experience.Service transition: This stage focuses on building, testing, and deploying new or modified services. It ensures that the services can operate effectively in the live environment and meet business requirements, such as when transitioning a new software application from development into production, ensuring it meets all testing criteria before going live.Service operation: This stage is responsible for the day-to-day management of IT services. It focuses on maintaining service quality, responding to incidents, and ensuring that services are delivered as expected. This could include monitoring a network to detect and resolve issues before they impact users, such as fixing a server outage to restore email access.Continual service improvement (CSI): This stage is about continuously assessing and improving IT services to ensure they meet changing business needs and provide maximum value. It involves analyzing performance data, identifying areas for improvement, and implementing changes. One example could be reviewing customer feedback and implementing changes to improve the user interface of a self-service IT portal.

Let’s consider an example: a large financial institution faces frequent disruptions in its online banking system, causing customer dissatisfaction and impacting business operations. The organization wants to reduce downtime, improve service reliability, and provide a better customer experience, so they adopt the ITIL incident management process. This process shows how to form a dedicated incident management team that is responsible for identifying, categorizing, and resolving incidents. The team is trained in ITIL best practices and equipped with an IT service management (ITSM) tool.

Using ITIL guidelines, incidents that are reported by customers or detected by monitoring systems are logged into the ITSM tool. Each incident is categorized based on predefined categories (e.g., network issues, software errors, or hardware failures) and prioritized based on impact and urgency.

The incident management team follows standard operating procedures (SOPs) and predefined workflows to respond to and resolve incidents efficiently. For critical incidents, escalation protocols are established to involve senior IT staff and subject matter experts when necessary.

ITIL emphasizes clear communication during incidents. The organization implements regular updates for stakeholders, ensuring customers are informed about the status of their issues and the expected resolution times.

After each incident is resolved, a post-incident review is conducted to identify the root cause and analyze the effectiveness of the response. Lessons learned are documented and used to refine incident management processes, train staff, and prevent recurrence.

An example of an ITSM tool is shown in Figure 1.2:

Figure 1.2: A screenshot of an ITSM tool

Figure 1.2 shows a dashboard with requests from a technician, showing the number that are open and overdue. The dashboard also features open requests by priority level, a gauge chart displaying the number of SLA-violated requests, and another gauge chart that highlights the number of unassigned open requests. This tool enables the IT department to track and manage service requests efficiently.

By following the ITIL framework, the financial institution improves incident response times, reduces the number of recurring incidents, and increases overall service reliability. This leads to enhanced customer satisfaction, better resource allocation, and reduced operational disruptions.

Governance frameworks can drastically increase the efficiency and effectiveness of an organization. Both COBIT and ITIL are tried and tested methodologies that undergo constant review. COBIT provides a holistic and detailed approach to considering the company and its IT operations as a whole. Rather than being a separate department, conflicting with the needs of day-to-day operations, COBIT helps IT and security align with the rest of the business and drive objectives.

On a day-to-day basis, ITIL will help the IT department respond to incidents and requests effectively and efficiently, which will help with operational running and even drive greater customer satisfaction.

With security programs and frameworks in place, your organization should be running smoothly and securely. However, things are never static, and change is always to be expected, whether it is due to new threats, shifts in business requirements dictated by the market, or even technological advancements such as generative AI. Changes can also be small, such as network updates, upgrading or replacing devices, or reconfiguring passwords and permissions.

Change can be disruptive and lead to system failures. However, effective management can help your IT infrastructure, organizations, and key stakeholders adjust seamlessly, as will be seen in the next section.

Change/configuration management

As your organization grows and adapts, IT operations and systems will also need to be configured. This could be a big change, such as adding a new office with a new network, or a small change, such as replacing a firewall or reconfiguring a subnet. However, even the most ad hoc adjustments, if not done with proper care and oversight, can have drastic impacts on the rest of the network. For example, if new routers are installed but admin passwords are not updated and shared, they could create security vulnerabilities.

Because of this, change and configuration management is a critical component of a secure IT environment. Changes should be planned, tested, approved, and documented, reducing the likelihood of vulnerabilities or misconfigurations being introduced. Consistent configurations and clear accountability help minimize security incidents and may even be vital regulatory requirements.

As important as monitoring the overall network is, proper management of asset life cycles, proper recording of configurations, and maintenance of your inventory are also vital. This will be discussed later in this section.

Effective change management follows agreed-upon processes, including approval, evaluation, testing, and review. A typical process might start with a request for change (RFC), then change evaluation and impact analysis, change approval, change planning, change testing, change implementation, change review, and change closure. Let’s take a closer look:

The process begins with someone identifying the need for a change. For instance, an IT team submits an RFC to upgrade the organization’s email server to improve performance and security.The proposed change is evaluated to understand its potential impact on the organization’s systems, processes, and users. In our example, before approving the email server upgrade, the IT team evaluates how the change might affect email access during business hours and what risks are involved if the upgrade fails. The change is reviewed and approved by the change advisory board (CAB) based on impact analysis, risk assessment, and alignment with business objectives. The board reviews the RFC for the email server upgrade and approves it after confirming that the risks are manageable and the benefits outweigh the potential disruptions. Approval can also be done by management.The IT team creates a change plan that schedules the server upgrade during off-peak hours, assigns tasks to specific team members, and outlines how they will communicate with stakeholders before, during, and after the change.The change should be tested in a controlled environment, such as a staging or test environment, to ensure that it will work as expected without causing unexpected issues. In our example, the email server upgrade is first tested in a lab environment that mirrors the production environment to verify that the upgrade process works and that the server performs correctly after the change.Following the approved change plan, implementation should be monitored closely to identify and address any issues that arise. The IT team performs the email server upgrade during the scheduled maintenance window, following the steps outlined in the change plan.After the change is implemented, a post-implementation review is conducted. After the email server upgrade, the IT team reviews the process, notes any problems encountered, and confirms that the upgrade achieved the intended performance improvements. Lessons learned are documented for future reference. The change process is formally closed after the review, and all documentation is updated to reflect the completed change. This includes updating the configuration management database (CMDB), something that will be covered later in this chapter, and any relevant asset inventory. In our example, this means that the RFC is marked as completed, and the CMDB is updated to reflect the new version of the email server in the organization’s infrastructure.

Asset management life cycle

All equipment either breaks down or becomes obsolete. Managing the life cycle of IT assets, such as laptops and servers, ensures that they are regularly updated, maintained, and replaced when necessary. This might include decommissioning old hardware to prevent security vulnerabilities.

The asset management life cycle is a comprehensive approach that’s used to manage and optimize the life cycle of an organization’s assets effectively. It covers all stages, from the initial planning and acquisition to the eventual disposal of the asset. In the context of cybersecurity and IT, asset management refers to identifying, tracking, and securing all assets, which could include hardware, software, data, and network components. This is illustrated in Figure 1.3:

Figure 1.3: The asset management life cycle

Here is a breakdown of each phase of the asset management life cycle:

Approval and acquisition: Required assets are procured while following the organization’s procurement policies. During acquisition, vendors, compliance standards, and purchase agreements are carefully considered.Deployment: After procurement, assets are installed and configured according to organizational standards. In the context of IT, this includes setting up servers, software, and security configurations, as well as establishing necessary network connections. All acquired assets are documented in an asset management system, where information such as serial numbers, configurations, owner, and location is recorded. This is critical for maintaining visibility and accountability.Monitoring and tracking: Once assets are deployed, continuous monitoring is necessary to track their performance, usage, and security status. This can include using automated asset management tools to monitor vulnerabilities, performance issues, and unauthorized modifications.Upgrade or replacement: Periodic assessments determine whether assets are still meeting the organization’s needs. The focus here is on performance, cost, compliance, and security. If an asset is no longer efficient or secure, an upgrade or replacement may be required. Based on the assessment, a decision is made to upgrade or replace an asset. For example, software may need version upgrades, or outdated hardware may need to be replaced with more secure and efficient alternatives.Disposal and decommissioning: Assets that have reached the end of their useful life must be decommissioned while following organizational policies and regulatory standards. This step includes data wiping, sanitizing, or securely destroying storage devices. When decommissioning IT assets, secure disposal is paramount to ensure that sensitive data is not recoverable. This includes using certified data destruction services or shredding hardware components that store confidential information. Upon disposal or decommissioning, the asset register should be updated to reflect the removal of the asset from the inventory. This is essential to maintain an accurate asset inventory for compliance and audit purposes.

To track organizational assets from initial acquisition through to decommission, it is important to have a centralized CMDB.

CMDB

A CMDB keeps track of all IT assets and their configurations. If a server is compromised, the CMDB helps identify all dependent systems and applications, enabling a thorough response.

Inventory

Within a network, there are numerous devices and pieces of software, all of which have their own life cycles, security updates, and risks. It is important to keep track of all devices. Adopting a CMDB ensures that an enterprise can maintain an up-to-date inventory of all software and hardware assets that the organization needs to manage. This helps ensure that unauthorized devices do not connect to the network—for example, PCs that don’t have the correct security patching—and all systems are properly licensed and patched.

Keeping track of your network state, the devices in it, and the software running on it will help to prevent security issues as well as help you troubleshoot issues when they do occur. Automation and informational dashboards help staff maintain an up-to-date inventory of company assets. Products such as Lansweeper can provide automated scans of network assets.
