Thread-topic: Snort Rule Advise.

Hi,

 

Could someone kindly advise if it is possible to achieve the following within a rule.

 

I am creating rules to trigger when specific words are seen within the payload, for example the word ‘ADS’ as below:

alert tcp any any -> any any (msg :"SecureADS"; sid:1000011; content:"ADS"; nocase; rev:1;)

But currently it will trigger if it sees NADS for example which is a menu option within an SGD environment.

 

Please advise how I can restrict the rule to trigger when only ADS is seen, this can appear anywhere in the payload.

 

Kind Regards

 

Tony
