IPS signature to match usernames?

Can an IPS be used to match usernames during RDP and or RPC sessions?

We have done some wireshark captures and searched the stream content for usernames with no success.

The servers are 2003 & 2008.

Perhaps MARS is the best solution here for reporting this?

Thanks

Re: IPS signature to match usernames?

If there is no fix pattern for the username field in RPC or if its encrypted (via NTLM hash etc.) then there is no chance you can match it using regex.If the field is predictable, then a custom signature can be made as desired.

The MARS box does not do any detection or regex matching itself, it just correlates the signature events received from the IPS, so I doubt MARS would help here.
