Security in the digital realm encompasses all measures taken to protect data, networks, and computer systems from unauthorized access, use, disclosure, disruption, modification, or destruction. It’s a broad field aimed at ensuring confidentiality, integrity, and availability (the “CIA Triad”).
Topics often covered are:
- Vulnerability Assessment: Identifying weaknesses in systems.
- Penetration Testing: Simulating attacks to find exploitable flaws.
- Secure Coding Practices: Writing code that is resilient to common attacks like SQL Injection and XSS.
- Network Security: Protecting the underlying infrastructure with firewalls, VPNs, and monitoring.
