Subject: [Snort-users] Invalid login attempts



Hi,



We are having a Snort test setup.  We are using free set of signatures (from Snort & ET) with Snort version 2.9.5 GRE - Build 103. Signatures were recently updated say 3-4 days before. We are updating signatures using the pre-defined rule set "Security" (Security over connectivity).



We have one question regarding detection of invalid login attempts for Sonicwall. Does Snort has signatures for detecting invalid login attempts to a SonicWall SSL VPN box (say for invalid login attempts while connecting to the VPN or somebody trying to bruteforcing the VPN box for admin credentials, both)? If yes, are signatures for it available in free set of signatures from Snort & ET? This question is because recently we have observed that Snort running with these signatures was unable to detect these activities.



Please let me know if there is any other information needed from my side for you to answer the said question.



Thanks.



Regards,

Anshuman
