Solution providers may see increased interest from clients about encryption technologies and guidance about its proper implementation. The NSA reportedly spent about $250 million to "covertly influence" product designs of private security technology vendors. The influence included inserting secret back doors or hidden vulnerabilities, enabling access points to commercial security software. And, in some cases, the back door apparently gave the intelligence agency access to encrypted data. While most security experts say the most widely used encryption protocol remains intact, implementation problems and configuration errors continue to open weaknesses. Companies that are serious about safeguarding intellectual property and other corporate secrets not only encrypt them, but they also do their own key management, a security expert recently told CRN.
