Introduction to remote access VPN

Throughout history, technology has been a driving force in shaping the way we live and work. This transformation began with simple tools, evolved with the invention of the internal combustion engine, and eventually led to the development of computers and networks. An illustrative example of this technological progression is the field of transportation. Thanks to extensive physical networks, such as roads, trains, and airplanes, people can now live and work beyond the confines of congested cities. Large segments of the population have relocated to suburban communities, giving rise to the well-known daily commute phenomenon.

Despite soaring fuel prices, many individuals have opted to stay in the suburbs. Today, with the rise of the Internet, people have the flexibility to work from almost anywhere. SSL VPN, a technology we will explore in this chapter, is a pivotal element in facilitating this ubiquitous access. Before delving into the intricate details, it's essential to comprehend how this technology can benefit you.

Many individuals are now part of what we call a 'virtual' organization. Employees in virtual organizations may not require a traditional office, cubicle, or parking space. Companies are increasingly embracing remote work, leading to the emergence of teleworkers. According to the International Telework Association and Council (ITAC), the number of U.S. employees working remotely has steadily increased since 1999. The ITAC commissioned a study conducted by Dieringer Research Group, which found that teleworking has grown by nearly forty percent since 2001. The ability to connect to the Internet from anywhere, at any time, makes teleworking possible. This process of remote Internet connectivity is now effortless, and with the advent of wireless technology, access is pervasive. Teleworking and remote computing encompass various scenarios, including:

Working on a laptop at a local coffee shop while sipping coffee (using wireless 802.11)

Checking online mail while on a train journey to meet a customer

Utilizing a customer's network to connect to your corporate network while on-site

Updating your resume and posting it to an Internet-based job site during a flight to Frankfurt

Accessing accounting data at an Internet café on 42nd Street in New York

Enjoying online games on your backyard deck (with your dog)

Working from your suburban house with the iconic white picket fence

Wireless Network: A wireless LAN, or WLAN, operates without physical wires. Computers and routers communicate with one another using a specified protocol and radio frequency circuits. Similar to television or cell phone signals, your home network can interconnect computers without the need for cables. This wireless networking protocol is known as IEEE 802.11, designed to ensure interoperability among different brands of WLANs. The 802.11 technology can also work with standard Ethernet through a bridge or Access Point (AP). Unlike standard Ethernet, wireless Ethernet utilizes Carrier Sense Multiple Access with Collision Avoidance (CSMACA), whereas standard Ethernet relies on Carrier Sense Multiple Access with Collision Detection (CSMACD). One significant advantage of the 802.11 standard is the ability of products from different vendors to seamlessly interoperate. This means that users can purchase wireless LAN cards from various manufacturers, and they will work together regardless of the brand.

Today, you can access the internet from nearly anywhere and at any time, with minimal restrictions in North America, Asia, and Europe. Soon, global access to the internet will be a reality. However, it's crucial to address one critical aspect: security. While the words 'anytime' and 'anywhere' hold true, the term 'secure' is not always guaranteed. In the current internet landscape, online traffic is rarely secure. Gone are the days of the 9600-baud modem, along with the naive belief that "everything is secure." "Access to the internet is no longer safe."

The internet serves as the communication backbone for a wide array of activities, extending beyond e-commerce. Today, the internet serves as a platform for various purposes, including:

Playing online games, posting resumes, and seeking new relationships

Supporting businesses through B2B (Business to Business), B2C (Business to Consumer), and B2E (Business to Employee) interactions

Messaging and email (albeit with the ever-persistent spam)
