Suresh,
Those look like alerts for custom Snort signatures (Added by AS)?
I assume then that you are not the administrator of the Snort IDS
sensors. You need to speak to whomever wrote those signatures and see
what the signatures detect on.
Looks like they were made for suspect port 80 traffic to 219.139.108.138?
What do you mean in your question, a way to decode the below messages?
Based on what I think you're asking:
1) Get the Snort rule. You'll want to locate the rules for the
sj-ids-int01 sensor, find the rule the custom rule thats triggering that
alert (probably in local.rules)
2) Get the packet that triggered it. Are you guys using any sort of
Snort monitoring tool or are you guys just sending Snort to syslog? As
you can see, the Syslog alerts don't contain the packet dump.
HTH.
