Hmm. Have you explore using ip reputation preprocessor? On Jul 19, 2012 9:03 PM, "Antonin" <antonin () libfy com> wrote:
thanks for your answer. I have a proxy server but my goal is not to block this kind of traffic (it's already the case with the proxy). I just want to be alerted when a user (or a malware, etc...) try to reach this kind of website. We have a SIEM tool, and we want to have an alert. 2012/7/19 Wei Chea Ang <weichea () gmail com>I think it will be easier if you use a proxy for this.

For example, I wan't to raise alert when users are going to websites with warez, cracks, serials, torrent, etc... Here is what I do: alert tcp $HOME_NET any -> any any (msg:"POLICY VIOLATION Illegal website Usage"; flow:to_server,established; content:"torrent"; nocase; http_header; metadata:service http; classtype:policy-violation; sid:1234567894; rev:5;) But I need to create one rule per keyword. Not very optimal. Do you have any other idea? Tips?
