This document provides an overview of information security topics including cyber attacks, the differences between cyber security and information security, the art and philosophy of hackers, and a brief history of hacking. It defines cyber attacks as assaults using computers against other computers or networks, and lists some common types like identity theft, malware, and denial of service attacks. It also distinguishes cyber security from information security, noting cyber security protects data in cyberspace from risks like malware while information security focuses on securing access to data and compliance. The document then provides a short excerpt about the hacker mindset and a link to learn more, and mentions two influential hackers, Kevin Mitnick and the Iranian group that carried out the Shamoon attack on Saudi A

Malware, phishing, spamming, spoofing, spyware, trojans and viruses.
Stolen hardware, such as laptops or mobile devices. Denial-of-service and distributed
denial-of-service attacks.

6. Cyber security vs information security
Cyber Security Information Security
Protects data in cyberspace Helps secure avenues to access data
Risks include malware and network
attacks
Need to secure misinformation and
entry
Hardened data using encryption Takes compliance and policies into
account

8. The History Of Hacking
Kevin Mitnick is the world's authority on hacking, social engineering, and security
awareness training. In fact, the world's most used computer-based end-user
security awareness training suite bears his name. Kevin's keynote presentations are
one part magic show, one part education, and all parts entertaining.
Considered the biggest hack in history in terms of cost and destructiveness . Carried
out by an Iranian attacker group called Cutting Sword of Justice. Iranian hackers
retaliated against Stuxnet by releasing Shamoon. The malware destroyed over
35,000 Saudi Aramco computers, affecting business operations for months.
