Summary

Cyber security is the practice of protecting systems, networks, programs, and data from unauthorized access, modification, or destruction. The core of information security is known as the CIA Triad: Confidentiality, Integrity, and Availability. Cybersecurity is not just a matter of technology, but also of processes and people using them.

Key points

The CIA Triad: Confidentiality, integrity, availability.
Threat is a dangerous act; vulnerability is a vulnerability that can be exploited.
Risk is the likelihood that a threat will exploit vulnerability to cause an impact.
Defense in depth: layered security, not relying on one tool.
Human error is often the entry point for cyberattacks.
