Which cybersecurity concept involves implementing multiple security layers?

The concept of implementing multiple security layers is referred to as Layered Defense. This approach is essential in cybersecurity because it creates a more robust security posture by delivering several protective measures at different points in the system.

Each layer operates independently, meaning that if one layer is compromised, others continue to provide defense. This strategy significantly enhances security as it makes it more challenging for attackers to breach all the layers, thereby increasing the chances of detecting and mitigating threats before they reach critical assets. A Layered Defense commonly includes firewalls, intrusion detection systems, antivirus programs, and secure coding practices, among others.

The other concepts listed, while important in the realm of cybersecurity, do not focus specifically on the idea of multiple overlapping layers of security. Network Segmentation, for instance, deals with dividing a network into segments to enhance performance and security but does not alone embody the holistic approach of layered protections. Intrusion Mitigation focuses on strategies to resist intrusions rather than layering security measures. Access Control works to regulate who can enter a system or resource, which is crucial but also does not represent the broader strategy of layering security.
