Objet : Re: [Snort-users] Detecting administrative share access

Hello. I have been trying to detect administrative share access on my network. I have read that the dcerpc2 processor can detect administrative share access and seems to be enabled by default in the snort.conf but I do not get any alerts when testing it by accessing \\192.168.1.10\C$ of \\192.168.1.10\ADMIN$.

I have also created a custom rule to detect administrative access:

alert any any -> $HOME_NET 445 (msg:"Admin share access"; pcre:"/(ADMIN\$)|(C\$)/i"; sid:1000200; rev:001; classtype:misc-activity;)

However, no alerts are triggered. What could the issue be?
