Introduction and Basic Terminology
Cyber security encompasses the protection of digital assets and information systems against unauthorized access and attacks. The foundational principles are framed within the CIA Triad—Confidentiality, Integrity, and Availability—each supported by various mechanisms. A comprehensive understanding of cyber threats helps in safeguarding against potential risks, while recognizing the importance of cyber-attack surfaces reveals vulnerabilities that need to be managed. Recent significant incidents highlight the critical need for robust security measures and proactive incident response plans.
