What do layered defenses in cybersecurity aim to achieve?

Layered defenses in cybersecurity aim to provide multiple levels of security by implementing various protective measures at different layers of the system. This approach is often referred to as "defense in depth" and ensures that if one layer of security fails, additional layers will still be in place to protect the system. By employing different types of security tools and practices, such as firewalls, intrusion detection systems, antivirus software, and access controls, organizations create a robust security posture that is harder for attackers to penetrate.

The philosophy behind layered defenses acknowledges that no single security measure can be foolproof. By distributing security responsibilities across various layers, organizations can better manage risks, respond to threats, and improve overall resilience against cyber attacks. This multi-faceted strategy not only offers redundancy in security but also allows for more complex attack detection and prevention capabilities, making it a crucial practice in effective cybersecurity management.
