Multi-Layer Security
Fleetingmulti-layer security
Multi-layer security is an approach to cybersecurity in which multiple defensive mechanisms are deployed in tandem to protect data and information. A methodology of this sort — in which one layer of security being compromised doesn’t break the entire system — is able to address a variety of attack vectors at once and decrease the likelihood of a successful breach.
In cybersecurity, experts often refer to this type of security as the “castle approach” due to its structural similarity to a medieval castle. To penetrate a castle, attackers must get through several layers of security, namely the moat, ramparts, drawbridge, towers, battlements, etc.
