In my recent review of Tripwire, I was remiss in not mentioning Solidcore S3 Control. Solidcore S3 Control, like Tripwire, offers more control to change management. The software provides real-time visibility of changes being made across a variety of infrastructure elements, adds accountability to validate change activity and can also develop policies that can enforce change policy. Thanks to an avid InformationWeek reader (and Solidcore) for pointing this out to me. We hope to get the products in our labs soon.
