Protection From the Perimeter to the Core
A decade ago, Internet security pioneer Bill Cheswick proposed a network security model that he famously characterized as a "crunchy shell around a soft, chewy center." Today, as more and more "outsiders" – remote users, business partners, customers, contractors – require access to corporate networks, enterprises are finding the idea of a "soft center" obsolete, if not downright dangerous.
In such an environment, which is also increasingly beset by so-called blended threats that dynamically target the vulnerabilities of isolated security products, enterprises must adopt an integrated strategy that addresses network security at all tiers: gateway, server, and client.
