This is a great security utility to be sure, but what about non-system files like those that constitute your Web site? Never fear: Tripwire, in partnership with Covalent, has recently released Tripwire for Web Pages into its security software stable. Tripwire . . . . This is a great security utility to be sure, but what about non-system files like those that constitute your Web site? Never fear: Tripwire, in partnership with Covalent, has recently released Tripwire for Web Pages into its security software stable. Tripwire for Web Pages works in much the same way as the flagship server product. After an initial scan of a Web site's pages, the server analyzes those pages before sending them to a browser. If a file has been modified without a Tripwire database update, customizable events are triggered, including delivering a "File not available" page to the visiting browser, rather than a page that may have been altered or defaced. This product has come along at just the right time, as hacktivist, black hat and script kiddie defacements increase, and corporate IT management staffs look to mitigate any embarrassment and downtime associated with a compromised Web server. Though site defacements can be accomplished by a security lapse as simple as an outdated FTP login, the resultant cleanup and downtime can be costly.
