Defense in Depth Law and Legal Definition

Defense in depth is the coordinated use of multiple security countermeasures for protecting the integrity of the information assets in an enterprise. Defense in depth minimizes the success rates of malicious hackers. Defense in depth can help system administrators and security personnel identify people who attempt to compromise a computer, server, proprietary network or ISP (Internet service provider). Components of defense in depth include antivirus software, firewalls, anti-spyware programs, hierarchical passwords, intrusion detection and biometric verification. Apart from electronic countermeasures, physical protection enhances the security of vital data against compromise, theft or destruction.
