What is Layer Security?
Layered security refers to security systems that use multiple components to protect operations at multiple layers or tiers. This term can also be associated with Defense in Depth, which is based on a slightly different idea that uses multiple strategies and resources to slow, block, delay, or hinder a threat until it is complete can be neutralized.
Layered security can also be referred to as layered defense.
The central idea behind layered security or defense is that it is more effective to use multiple strategies to protect systems from a wide variety of attacks. Layered security can encompass security protocols at the system or network level, at the application level or at the transmission level, with security professionals able to focus on data that is used at rest.
Layered security efforts attempt to address issues with different types of hacking or phishing, denial of service and other cyber attacks, as well as worms, viruses, malware and other types of more passive or indirect system invasions.
