Here's the breakdown of the SID block: [1:300001:1] ^ ^ ^ | | | | | +-- Revision number (Rev) | | | +------- Snort ID (SID) | +----------- Generator ID (GID) The generator ID is the subsystem within Snort that generated the event. The references for this data can be found in generators.h, but for the sake of enlightenment (not the window manager) a GID of 1 means the primary detection engine generated the event. The SID is the identification number of the event. These numbers are unique to each Snort signature and each detectable event that the preprocessors can generate. If you want to find out which signature generated an event, just grep *.rules for the SID. The revision number is the version of the rule that went off, as rules are updated and evolve these numbers will increment. Hope that helps! -Marty On 3/4/02 1:11 AM, "Bill McCarty" <bmccarty () apu edu> wrote:
I'm writing a program to process lines in Snort's Fast Alert Log. However, I can't decipher several of the fields. Here's a typical log entry: 03/03-22:06:32.396957 [**] [1:300001:1] Service Hunt [**] [Classification: Misc activity] [Priority: 3] {TCP} xxx.xxx.xxx.xxx:40144 -> xxx.xxx.xxx.xxx:21 Can someone tell me what information can appear in the two fields containing asterisks? In my logs I find no entry in which they contain anything else. And, can someone tell me the meaning of the number preceding the sid (3000001) and rule revision number?
