Introduction to Cybersecurity
Cybersecurity is the practice of protecting systems, networks, and data from digital attacks, unauthorized access, or damage. As our reliance on technology grows, cybersecurity becomes increasingly vital in both personal and professional contexts. The goal is to ensure that sensitive information remains secure and that systems continue to function without disruption.
At the core of cybersecurity principles is the CIA Triad, which stands for:

CIA Triad
1. Confidentiality
• Definition: Ensuring that information is only accessible to those with authorized access.
• Goal: Protect sensitive data from unauthorized disclosure.
• Example: Using encryption, passwords, and access controls to keep personal or business information private.
2. Integrity
• Definition: Ensuring that information is accurate and unaltered.
• Goal: Prevent unauthorized modifications and ensure data is trustworthy.
• Example: Hashing, digital signatures, and version control systems help verify data integrity.
3. Availability
• Definition: Ensuring that systems and data are accessible to authorized users when needed.
• Goal: Maintain uptime and reliable access to information and services.
• Example: Redundant systems, backups, and DDoS protection support availability.
