Abstract

Systems and methods for performing application control constraint enforcement are provided. According to one embodiment, file system or operating system activity of a computer system is intercepted relating to a code module. A cryptographic hash value of the code module is checked against a local whitelist database containing cryptographic hash values of approved code modules, which are known not to contain viruses or malicious code. The local whitelist database also contains execution constraint information. When the cryptographic hash value matches one of the cryptographic hash values of approved code modules, authority of the computer system or an end user of the computer system to execute the code module is further validated if the execution constraint information so indicates by performing a constraint check regarding the code module. If the authority is affirmed by the constraint check, then allowing the code module to be executed.
