This morning I briefed a client on the results of a Network Security Monitoring Assessment I performed for them. I model my NSM Assessment on the NSA-IAM, which uses interviews, observation, and documentation review to assess security postures. My NSM Assessment uses the same techniques to identify problems and provide recommendations for improving intrusion detection and NSM operations.
During one of the briefings the top manager asked for my opinion on using open source security tools. He wanted to know the guidelines I use to determine if an open source tool is appropriate for use in the enterprise. I told him I am more likely to trust open source products that are developed by companies with whom I have a relationship of some sort (like Snort and Sourcefire, Nessus and Tenable, or Argus and Qosient).
I was wondering what sorts of suggestions you might have governing open source security tools. The intent of the manager's question was to assess how I end up "trusting" open source tools. I believe the commercial tools should not be trusted simply because they are commercial, in an age where programming can be outsourced to parties ultimately unknown. What are your thoughts?
