Rules utilisation: msg#00160security.ids.snort.sigs
Hello, There is something that I don't understand. I was believing that the bleeding-edge rules was done in order to test the validity of the rules. However, I never see that there is a mecanism that allow to collect experiences with bleeding-edge rules. I give an example: Monday, a infected computer has been plugged on the internal network I am managing. This computer has initiating an IRC connection and receive instructions. A dozen computers are then infected with an unknow virus exploiting the Lsa vulnerability. Some rules have been usefull in such circonstances : the rules on LSA, the rules on IRC communication on non standard port, and RXBOT rules. In my opinion, these kind of rules, that have proved to be usefull should be distinguished. I don't know exactly how it is possible to do such a thing. Perhaps a vote, or something that can summarize the worth of the rules on at least 3 criterions: criticality number of positives number of false positives Thierry ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
