VULNERABILITY SHIELD SYSTEM

Security against computer software attacks is provided by blocking the use of known software vulnerabilities by attackers. Rather than merely discovering attacking software after it has installed itself into a computer system as in the prior art, software with a known vulnerability is monitored so that when it takes a potentially dangerous action, such as creating new attack software, that new attack software is marked and then prevented from loading. If the newly attack software cannot load, it cannot execute thus thwarting use of the newly written software to perform whatever nefarious act was intended by the attacker.
