Here are some ArcMc (2.0) breach rules. Hopefully the next release of ArcMc will have most of this pre-configured as standard checks.
The attached document contains "hardware form factor product" rules as noted on pg. 139 of the ArcSight Management Center 2.0 Administrator's Guide as well as a few others.
Please share additional breach rules to compile and hopefully we can all have functional System Monitoring in ArcMc .
