And if you read a little more down the manual you will find the following which should answer part of your question. <SNIP> 3.4.7 priority The priority tag assigns a severity level to rules. A classtype rule assigns a default priority (defined by the config classification option) that may be overridden with a priority rule. Examples of each case are given below. 3.4.7.1 Format priority:<priority integer>; 3.4.7.2 Examples alert tcp any any -> any 80 (msg:"WEB-MISC phf attempt"; flags:A+; \ content:"/cgi-bin/phf"; priority:10;) alert tcp any any -> any 80 (msg:"EXPLOIT ntpdx overflow"; \ dsize:>128; classtype:attempted-admin; priority:10 ); </SNIP> On Wed, Aug 22, 2012 at 12:19 AM, mohamad hosein jafari <smhjafari68 () gmail com> wrote:
thanks But I read and did the work that you said and at last I found the links like these links : http://www.aldeid.com/wiki/Snort-alerts http://www.genome.ist.i.kyoto-u.ac.jp/snsn/130/54/21/dest130.54.21.199-all.html http://www.snort.org/search/results?limit=25&page=1&q=TCP And Also first I want to write some rules and classify alerts . but it had overlap and I think that was not complete So I read snort rules to know why snort team create these classtype . That was reson that I want to know snort classtype . also alert's name and explanation is not enough for my request . so I need more explain for each classtype that is in this link : http://manual.snort.org/node31.html#SECTION00444000000000000000 Thanks On Tue, Aug 21, 2012 at 9:08 PM, Mike Hale <eyeronic.design () gmail com> wrote:Mohamad, You're asking a really broad question. The rule alert is fairly self explanatory. A better way to obtain your answer is to do the following: - Read the documentation governing Snort rules - Understand the documentation governing Snort rules - Write some rules yourself and understand what they do - Look at the rules you have questions about and, using your newfound knowledge, understand what they do. If you still don't understand what specific rules do, then feel free to post a question; you'll likely get an answer.

Or do rule writers write more explanation than alert Msg explanation in any reference?

You need to read the manual for how the rules work and then you need to read the references found in the rules themselves. We're not going to explain 22,000+ rules. :) Thanks, but you need to read some documentation.the key factor is that there is no reference other than the one conf file... other than that, any rule writer is free to use any classification the desire for their rule... there are times that the MSG of a rule gives more information than the classification... especially considering that there are only really 3 classification numericals used...-- Joel Esler Sent from my iPad On Aug 21, 2012, at 9:01 PM, mohamad hosein jafari <smhjafari68 () gmail com <mailto:smhjafari68 () gmail com>> wrote:Yes .

For instance, non-standard-protocol, actually only has one rule that uses it. The classifications are assigned by the VRT member who writes the rule, and then when it's published it's reviewed to see if that makes sense. yes I want the things that you said . But where can I find this? In other words where rule writers put their classification's explain on? Also I want some explain about ALL snort alerts consist : Type , mechanism , effect And its resource . I have these two question . And I want reference for these. Can you help me?
