        Team,

         

        Are the new rule names new or are the replacing old name rulesets?  I ask due to:

        Oct 24 15:25:31 10.10.254.110 snort[6176]: /opt/etc/snort/rules/VRT-shellcode.rules(11) GID 1 SID 14986 
duplicates previous rule. Using higher revision.

        Oct 24 15:25:31 10.10.254.110 snort[6176]: /opt/etc/snort/rules/VRT-shellcode.rules(63) GID 1 SID 23236 
duplicates previous rule. Using higher revision.

         

        VRT-indicator-shellcode.rules:alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"INDICATOR-SHELLCODE x86 fldz 
get eip shellcode"; content:"|D9 EE D9|t|24 F4|X"; metadata:policy balanced-ips drop, policy security-ips drop; 
classtype:shellcode-detect; sid:14986; rev:5;)

         

        VRT-shellcode.rules:alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"SHELLCODE x86 fldz get eip shellcode"; 
content:"|D9 EE D9|t|24 F4|X"; metadata:policy balanced-ips drop, policy security-ips drop; classtype:shellcode-detect; 
sid:14986; rev:4;)

         

        Should I remove shellcode.rules and just use indicator-shellcode.rules?  Thanks all.
