Foundations, Standards, and Principles of Information Security

In today’s information-centric environment, the concept of information security is paramount and is now on par with other business functions. Irrespective of their market share, private or public status, or geographical location, businesses are being pushed to move online in order to stay relevant.

In the 21st century, we have all experienced the information revolution. Data is stimulating the information revolution in the same way that oil catalyzed the industrial revolution. In today’s environment, data is the raw resource that must be studied, interpreted, and retrieved with care in order to provide significant insights to its users.

The difference between oil and data is that the volume of oil is reducing across the world, whereas the amount of data is growing day by day. Data has become a valuable commodity and fuel source in today’s world.

On the other hand, data-related cybercrime such as data theft is expanding exponentially. A data breach occurs when a company unwittingly exposes critical information that might cause damage to a company’s reputation, brand value, and customer trust, or even result in regulatory penalties.

The average cost of a data breach was $4.35 million in the year 2022, according to IBM’s Cost of a Data Breach Report 2022. While the average cost per record was $164 in 2022, the cost per record has climbed considerably since 2020. Hackers are primarily interested in a company’s customer information because they can use it to blackmail the company or sell the information to competitors. Data has become, on average, more valuable than any other asset. Information security principles guide the entire concept of data security.

This chapter will explain the fundamentals of Information Security, including why it’s important and how security frameworks can help reduce risk and develop a mechanism to manage information security across an enterprise. The key topics covered are the following:

The CIA triadInformation security standardsUsing an information security management systemThe ISO 27000 series

The CIA triad

InfoSec, the shorthand for information security, refers to procedures designed to secure data from unauthorized access or modification, even when the data is at rest or in transit. It covers a broad range of topics, including safeguarding your digital assets, which is where you hold sensitive data.

Information security relies on three pillars known as the CIA Triad: Confidentiality, Integrity, and Availability, the preservation of which is defined in ISO/IEC 27000. See Figure 1.1 for a visual representation of the following three pillars:

Confidentiality – Providing access only to authorized personnel who need accessIntegrity – Maintaining the information’s accuracy and completenessAvailability – Making sure the information is available to authorized users when they need it

Figure 1.1 – CIA triad

Let’s see what each of the pillars in the triad means for information security.

Confidentiality

When an organization takes steps to keep its information private or secret, it is referred to as confidentiality. In the real world, this means limiting who has access to data in order to keep it safe from unwanted disclosure. Unauthorized disclosure of information or unauthorized access to information systems can be prevented by implementing confidentiality safeguards. For the confidentiality principle to be effective, sensitive information must be protected and only those who need access to accomplish their job responsibilities should be able to see or access it.

Confidentiality is required to prevent sensitive information from leaking to the wrong people. It is possible to safeguard user data by using authentication controls such as passwords and the encryption of data that is in transit or at rest to keep it confidential.

Integrity

Integrity refers to the ability of a person or thing to stand on their or its own two feet. In the same sense, integrity in information security entails the safeguarding of data from uncontrolled or unauthorized additions, deletions, or modifications. Integrity is based on the idea that data can be trusted to be accurate and not improperly altered.

The idea of non-repudiation, or the inability to refute anything, is closely linked to integrity. Non-repudiation of information and services is ensured by this criterion and thus provides traceability of the actions conducted on them. At all times, accuracy and consistency in data are vital. You must be prepared to show that document credibility has been maintained, particularly in legal circumstances, when it comes to integrity. Hashing, digital signatures, and digital certificates are often employed to ensure the integrity of data.

Availability

It is useless for a business to have valuable systems, apps, or data that can’t be easily accessed by the people who need them. Being available implies all systems and apps are working as expected, and resources are available to authorized users in a timely and reliable manner. The goal of availability is to ensure that data and services are available when needed to make decisions.

The accessibility of the system and services provided to authorized users is dependent on the availability factor because the system and services should be available whenever the user needs them. Redundancy of important systems, hardware fault tolerance, frequent backups, extensive disaster recovery plans, and so on, are all ways to assure availability.

Accountability and cyber resilience

Accountability entails assigning explicit obligations for information assurance to each person who interacts with an information system. A manager responsible for information assurance can readily quantify the responsibilities of an employee within the context of the organization’s overall information security plan. A policy statement saying that no employee shall install third-party software on company-owned information infrastructure is one example. To be resilient in the face of cyberattacks, a business must be capable of anticipating them, preparing for them, and responding to them appropriately. This aids an organization in combating cyber threats, reducing the severity of attacks, and guaranteeing that the company continues to exist even after an attack has taken place. This is cyber resilience.

The CIA triad forms the foundation of information security standards such as ISO/IEC 27001. Let’s now look at some of the standards that are accessible in the information security sector.

Information security standards

Standards provide us with a common set of reference points that allow us to evaluate whether an organization has processes, procedures, and other controls that fulfill an agreed-upon minimum requirement. Depending on the needs of the business or stakeholders, an organization may build and manage its own procedures in accordance with information security principles. It offers third parties such as customers, suppliers, and partners confidence in an organization’s capacity to deliver to a specific standard if that business is compliant with the standard.

This can also be a marketing strategy whereby the company can gain a competitive advantage over other organizations. When customers are evaluating a company’s products or services, for example, an organization that is compliant with a security standard may have the edge over a competitor who is not.

On the other hand, some regulatory and legal requirements may specify certain standards that must be met in certain circumstances. Suppose your company stores, processes, or transmits cardholder data. In this case, you must be in compliance with the Payment Card Industry Data Security Standard (PCI DSS). There are a variety of organizations involved in accepting credit and debit cards and the PCI DSS applies to each and every one of them. Major credit card firms such as Visa and Mastercard have identified these criteria as being the industry benchmark. Failure to comply with these standards may result in fines, increased processing fees, or even the refusal to do business with certain credit card companies.

Furthermore, if you are supposed to be compliant with a standard but are not, and you suffer a security breach as a result, you may be subject to legal action from the consumers who were harmed as a result of the breach.

Standards can also assist firms in meeting regulatory requirements such as those imposed by the Data Protection Act, Sarbanes–Oxley Act (SOX), Health Insurance Portability and Accountability Act (HIPAA), and other similar legislation. Utilizing standards to establish a solid foundation for managing and protecting your information systems will make it easier for your organization to comply with current and future regulatory obligations than for an organization that does not use standards.

Let’s have a quick look at some of the important standards in the field of information security.

The ISO/IEC 27000 family of information security standards

The ISO 27000 Family of Information Security Management Standards is a collection of security standards that form the basis of best-practice information security management. ISO 27001, which establishes the requirements for an Information Security Management System (ISMS), is the series’ backbone.

ISO 27001 is a global standard that defines the criteria for an ISMS. The structure of the standard is intended to assist companies in managing their security procedures in a centralized, uniform, and cost-effective manner.

Payment Card Industry Data Security Standard (PCI DSS)

The PCI Security Standards Council (PCI SSC) is an independent organization founded by Visa, MasterCard, American Express, Discover, and JCB to administer and oversee the PCI DSS. According to this regulation, companies, financial institutions, and merchants must comply with a set of security criteria when dealing with cardholder data. A secure environment needs to be maintained to receive, process, store, and transmit cardholder information.

Federal Information Security Management Act (FISMA)

The Federal Information Security Management Act (FISMA) is a set of data security principles that federal agencies must follow in order to preserve and secure their data. Private enterprises that have a contractual connection with the government are likewise subject to FISMA’s regulations.

Government data and information are protected, and governmental expenditure on security is kept under control. FISMA established a set of regulations and standards for government institutions to follow in order to meet data security objectives.

Health Insurance Portability and Accountability Act (HIPAA)

In order to protect the privacy and confidentiality of patient health information, the Health Insurance Portability and Accountability Act (HIPAA) of 1996 mandated the development of national standards. This is also known as the Kennedy–Kassebaum Act.

Health information that may be used to identify a specific individual is covered by the HIPAA, which applies to all forms of protected health information (PHI). All covered entities such as healthcare providers, health plans, and healthcare clearinghouses are under the Health Insurance Portability and Accountability Act of 1996.

Due to the security standard in place, patients may rest easy knowing that the fundamental health-related information they provide will be kept confidential.

NIST Cybersecurity Framework (NIST CSF)

The NIST framework for cybersecurity is a useful tool for organizing and improving your cybersecurity program. In order to assist businesses to establish and enhance their cybersecurity posture, this set of best practices and standards was put together.

A cybersecurity program built on the NIST Cybersecurity Framework (NIST CSF) is widely regarded as the industry standard. To assist enterprises in managing and reducing cybersecurity risk, the NIST CSF provides suggestions based on existing standards, guidelines, and practices.

No matter where they are located, all organizations may use this framework despite its original intent to protect important US infrastructure corporations.

SOC reporting

An internal control report developed by the American Institute of Certified Public Accountants (AICPA) is called the System and Organization Controls (SOC) for service organizations. Using SOC reports, service providers may increase their customers’ trust in the services they deliver, as well as their own internal control over those services. SOC 1, SOC 2, and SOC 3 are the three types of reports that can be used based on the requirements.

The SOC 1: SOC for Service Organization: ICFR report (type 1 or 2) evaluates an organization’s internal financial reporting controls in order to evaluate the impact of the controls of the service organization on the financial statements of its customers.

The purpose of the SOC 2: SOC for Service Organizations: Trust Services Criteria report (type 1 or 2) is to reassure customers, management, and other stakeholders about the appropriateness and efficacy of the service organization’s security, availability, processing integrity, confidentiality, and privacy measures (trust principles).

The SOC 3: SOC for Service Organizations: Trust Services Criteria for General Use report is a condensed version of the SOC 2 (type 2) report for consumers who want assurance regarding the security, availability, processing integrity, confidentiality, or privacy controls of service organizations. SOC 3 reports may be freely disseminated since they are general-purpose reports.

Cybersecurity Maturity Model Certification (CMMC)

To examine its contractors’ and subcontractors’ security, competence, and resilience, the US Department of Defense uses the Cybersecurity Maturity Model Certification (CMMC). This framework’s goal is to make the supply chain more secure by eliminating vulnerabilities. Control practices, security domains, procedures, and capabilities make up the CMMC.

Five levels of management are utilized in the CMMC architecture. The lowest maturity level is level 1, while the highest is 5. There are tiers of service that contractors are expected to provide depending on the amount of data they manage under the contract. Achieving each level of certification necessitates meeting particular standards by collaborating with various cybersecurity elements.

Information security standards help prove that the organization meets the stipulated data security levels and is compliant. These standards need to be effectively implemented and managed, and that is the role of an Information Security Management System (ISMS).

Using an information security management system

It is an open secret that every business is a target for cyberattacks. Despite the fact that data breaches are growing increasingly catastrophic, many firms still believe they will never be victims. If you have strong defenses, you can prevent most attacks and prepare for a breach. People, procedures, and technology are the three ISMS pillars that help an organization to achieve adequate security compliance.

An ISMS demonstrates the organization’s approach to information security. It will help you detect and respond to threats and opportunities posed by your sensitive data and any associated assets. This safeguards your organization and business processes from security breaches and protects them from disruption if they occur.

An ISMS is a framework for establishing, monitoring, reviewing, maintaining, and enhancing an organization’s information security compliance in order to achieve business and regulatory requirements. It is designed to identify, mitigate, and manage risks effectively by conducting a risk assessment and considering the firm’s risk appetite. Analyzing information asset protection requirements and implementing appropriate controls to ensure that these information assets are protected, as needed, helps in the effective deployment of an ISMS. An ISMS consists of the policies, processes, guidelines, allocated resources, and associated activities that an organization controls together to protect its information assets.

Information is data that is organized and processed, and which has a meaning in context for the receiver. Like other key business assets, it is critical to the operation of an organization and, as such, must be adequately secured. Electronic or optical media may store digital information (such as data files), while paper-based information (such as documents) or tacit knowledge among personnel can be used to store information as well. It can be sent via courier, email, or verbal conversation, among other methods. It must be protected regardless of how it is sent.

Information is reliant on information and communications technologies and infrastructure in many enterprises. This technology is frequently a critical component of an organization, assisting in generating, processing, storing, transferring, protecting, and destroying information.

Confidentiality, availability, and integrity form the three main dimensions of information security. Implementing and managing adequate security controls as part of an ISMS that addresses a wide range of possible risks helps reduce the effect of information security events, thereby ensuring long-term organizational success and continuity.

Controls are implemented according to the risk management process and managed through an ISMS to safeguard identified information assets in order to accomplish information security. These controls include policies and processes, as well as procedures and organizational structures. In order to meet the organization’s specific information security and business objectives, controls must be established, implemented, evaluated, reviewed, and, if necessary, upgraded. A company’s business activities must be taken into consideration while implementing information security controls.

Management entails actions aimed at directing, controlling, and continuously improving an organization within proper organizational structures. Management activities are the actions, styles, or practices of organizing, managing, directing, controlling, and regulating resources. Small enterprises may have a flat management structure with just one person, whereas large corporations may have hierarchies with dozens or even hundreds of people.

From an ISMS perspective, management includes the oversight, support, and decision-making essential to meet the business objectives and regulatory requirements by ensuring the security of the organization’s information assets. Information security management is exemplified by developing and implementing necessary policies, processes, and guidelines, which are subsequently implemented across the organization.

A management system makes use of a framework to help an organization accomplish its goals. Incorporating a management system means considering the organization’s structure, policies, and planning activities, along with roles and duties.

An information security management system helps an organization to do the following:

Meet all interested parties’ information security requirementsDesign and execute the organization’s tasks more effectivelyRealize the information security goalsComply with all applicable laws, regulations, and industry best practicesEnsure systematic management of information assets

Principle of least privilege and need to know

According to the Principle of Least Privilege (POLP), a person should only be granted the privileges necessary to carry out their job. POLP also limits who has access to apps, systems, and processes to only those who are authorized. POLP is implemented in the Role-Based Access Control (RBAC) system, which guarantees that only information relevant to the user’s role is accessible and prohibits them from obtaining information that is not relevant to their role.

Following the POLP lowers the danger of an attacker compromising a low-level user account, device, or application, giving them access to vital systems or sensitive data. By using the POLP, compromises can be contained to the source location, rather than spreading throughout the entire system.

The need-to-know concept can be enforced through user access controls and permission procedures, and its goal is to ensure that only individuals who are authorized have access to the information or systems they need to perform their jobs.

According to this rule, a user should only have access to the data necessary to perform their work. Need to know implies that access is granted based on a legitimate requirement and is then revoked at the end of the project.

An ISMS reflects an organization’s attitude toward protecting data. Implementing an ISMS can be particularly important to an organization in protecting its own data as well as its clients’.

Why is an ISMS important?

An ISMS is crucial because they provide a structure for safeguarding a company’s most confidential data and assets. They aid businesses in spotting threats to their data and assets and devising strategies to counteract them.

According to recent PwC research, one in every four businesses worldwide has had a data breach that cost them between $1 and $20 million or more in the last three years. The average cost of a data breach in 2022 was $4.35 million, according to IBM and Ponemon’s 2022 research. Last year, the average breach cost $4.24 million. From $3.86 million in 2020, the average cost has increased by 12.7%.

A leading e-commerce company was fined $877 million for breaking GDPR cookie regulations, a telecom company paid $350 million to resolve a class action lawsuit over a data breach in early 2021, and a software company was penalized $60 million for misleading Australian customers about location data.

A study by the British Standards Institution (BSI) found that 51.6% of organizations with a certified ISMS reported fewer security incidents.

An ISMS helps an organization devise a plan for handling sensitive information, such as personal and confidential business information, in a systematic way. This reduces the chances of a data breach and the financial and reputational damage it can cause. An ISMS helps businesses comply with applicable laws and regulations, such as the GDPR and HIPAA, in order to avoid penalties and reputational damage.

It is necessary to address the risks connected with an organization’s information assets. All of an organization’s information assets have an associated risk, which needs to be addressed through risk management. Information security needs risk management, which incorporates risks posed by physical, human, and technological threats to all types of information stored or used by the company. This strategic choice must be seamlessly integrated, scaled, and updated to match the organization’s needs when an ISMS is designed for an organization.

The design and execution of an ISMS are influenced by a variety of factors, including the organization’s goals, security requirements, business processes, and size and structure. All stakeholders in the firm, including consumers, suppliers, business partners, shareholders, and other key third parties, must be taken into account while designing and operating an ISMS.

The importance of an ISMS cannot be overstated. An ISMS is a key facilitator of risk management initiatives in any sector. Data access and management become more challenging to govern due to public and private network interconnectivity and the sharing of information assets. Additionally, the proliferation of mobile storage devices carrying information assets has the potential to erode the effectiveness of existing controls.
