A CISCO-based course on cybersecutiry essentials
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.
Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative. -

Welcome to Cybersecurity - A World of Experts and Criminals!
Many of the world’s original hackers were computer hobbyists, programmers and students during the 60’s. Originally, the term hacker described individuals with advanced programming skills. Hackers used these programming skills to test the limits and capabilities of early systems. These early hackers were also involved in the development of early computer games. Many of these games included wizards and wizardry.
As the hacking culture evolved, it incorporated the lexicon of these games into the culture itself. Even the outside world began to project the image of powerful wizards upon this misunderstood hacking culture. Books such as Where Wizards Stay up Late: The Origins of The Internet published in 1996 added to the mystique of the hacking culture. The image and lexicon stuck. Many hacking groups today embrace this imagery. One of the most infamous hacker groups goes by the name Legion of Doom. It is important to understand the cyber culture in order to understand the criminals of the cyber world and their motivations.
