      A New Look at Layers
      While emerging classes of tools may fend off attacks at multiple layers of a security strategy, there are pitfalls if the tools are not properly configured, managed or integrated with existing systems.

      Layer 1: Perimeter Security
      Layer 2: Host Security
      Layer 3: Identity and Access Management
      Layer 4: Network Access Control
      Layer 5: Vulnerability Management
      Layer Integration: Pulling It All Together

      Security is a many-layered thing for most I.T. managers. Attacks may target network, server or application vulnerabilities. Blended threats combine multiple attack vectors Trojan horses, worms and viruses, for example in an attempt to outflank an organizations defenses.

      In response, enterprises erect a series of barriers on the principle that an attack that beats one security measure wont get past other protections. This approach goes by several names: layered security, defense-in-depth and, on the folksy side, belt and suspenders. But the underlying premise is the same.
