Hello Everyone,
I changed community rules with my own rules and I realize that SNORT just
prints alert messages maximum 5 times to console if it finds more than 5
alerts. For instance, I inspect one packet's payload with WireShark and
wrote one rule which matches with packet's payload. I wrote this rule 20
times to rule file and I ran Snort. Snort gave me just 5 alert messages.
How can I increase this alert count ? I am working on a Project and I am a
beginner. I am very pleased if you can help me.
Example:
Rule File:
alert tcp any any -> any any (msg:"Feature1"; content:"#JN1"; nocase; sid:1)
alert tcp any any -> any any (msg:"Feature2"; content:"#JN1"; nocase;
sid:2)
alert tcp any any -> any any (msg:"Feature3"; content:"#JN1"; nocase;
sid:3)
.
.
.
alert tcp any any -> any any (msg:"Feature20"; content:"#JN1"; nocase;
sid:20)
Snort Output:
