Protecting against 0day exploits

There is simply no specific defense against 0day exploits. Each 0day exploit is unique, and only the attacker knows the full details of the 0day vulnerability. However, there are some steps that an organization can take to minimize the damage done by 0day vulnerabilities.

Defense in Depth

There is simply no substitute for defense in-depth for organizations. Defenses are layered, protecting sensitive data and critical systems through many different types of defense mechanisms. This forces the attacker to increase the intelligence-gathering effort needed for successful exploitation, as he will have to understand each defensive layer protecting the desired information. A solid defense in Depth strategy also dramatically increases the sophistication and effort required for a successful exploit, as the attacker must now bypass many defenses and not just one. Defense in Depth cannot guarantee safety from exploitation attempts by sophisticated attackers, but it does increase the footprint and increase the likelihood of early detection.
