support for base64_decode from snort's ruleset
I'm running pfSense 2.1.5-RELEASE (amd64) on (nano) FreeBSD 8.3-RELEASE-p16 with Suricata 2.0.3 pkg v2.0.2 and snortrules-snapshot-2962.tar.gz with snort 'balanced' IPS rules. I'm seeing the following in my logs:
18/9/2014 -- 14:04:22 - <Error> -- [ERRCODE: SC_ERR_RULE_KEYWORD_UNKNOWN(102)] - unknown rule keyword 'base64_decode'.
There seem to be only a few snort rules that cough up this message.
