Using regexp's To Search IDS Data -- Patented

Posted by timothy on from the oh-sure dept.

MiniGhost writes "Well... the USPTO is at it again! A recent search of their online patent database reveals a new patent issued on Nov 26, 2002. Apparently cisco has been issued patent #6,487,666, titled 'Intrusion detection signature analysis using regular expressions and logical operators.' So now they are claiming patent rights on the use of regular expressions and logical operators for IDS usage. It's only a matter of time before some corporation patents the stick man now!!"

    READ THE DAMN PATENT!
    (yes, I know that you'll need to copy the patent number into the seach box, becuase the link is wrong, or just Use the link provided here)

    Now also, they aren't pattenting the use of regexps in searching logs, they're pattenting the use of Regexps in conjunction with logical operations in **Generating** alerts. What i'd be interested in seeing is how this impacts of what snort is doing, and has been doing for quite some time now.
