Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise. Supply chain compromise of software can take place in a number of ways, including manipulation of the application source code, manipulation of the update/distribution mechanism for that software, or replacing compiled releases with a modified version.
A patch management process should be implemented to check unused applications, unmaintained and/or previously vulnerable software, unnecessary features, components, files, and documentation.
Continuous monitoring of vulnerability sources and the use of automatic and manual code review tools should also be implemented as well.
Use verification of distributed binaries through hash checking or other integrity checking mechanisms. Scan downloads for malicious signatures and attempt to test software and updates prior to deployment while taking note of potential suspicious activity.
