1. What does 'Defense in Depth' mean in cybersecurity?
Difficulty: MediumType: SubjectiveTopic: Security Design
Defense in Depth is a layered approach to cybersecurity. Instead of relying on a single line of defense, it stacks multiple protective measures at different levels. For example, an organization might use a firewall, intrusion detection system, antivirus software, strong authentication, and user awareness training. Each layer covers potential gaps left by others. This strategy ensures that even if one control fails, additional layers can still prevent or slow down an attacker.
