Security Technical Implementation Guides (STIGS).
http://iase.disa.mil/stigs/index.html
These are official guides used by the DoD to securely configure (harden) DoD IT assets. At the moment DISA/FSO (the office that develops and releases these) had not posted an updated STIG for SEP. Due to this we will have to apply the previous SAV 10 STIGS to the SEP product to the extent that the particular setting or configuration option still exists. I was looking for an official Symantec "secure configuration" type document for SEP to help augment our efforts.
In our particular environment we can only deploy SEP as an AV/ASW un-managed client; however, if the only Symantec documentation is for managed clients, it is likely we could extrapolate the un-managed configuration from that.
