OfficeScan client validation
refers to the process of evaluating
an OfficeScan client’s
security posture and returning instructions for the
OfficeScan client to perform
if the Policy Server considers it to be at-risk. The Policy Server
validates
an OfficeScan client by
using configurable rules and policies.
Below is the sequence of events that occurs when an OfficeScan client attempts
to access the network:
-
The Cisco Network Access Device starts the validation
sequence by requesting the security posture of the client when it
attempts to access the network.
-
The Network Access Device then passes the security posture
to the ACS server.
-
The ACS server passes the security posture to the Policy
Server, which performs the evaluation.
-
In a separate process, the Policy Server periodically polls
the OfficeScan server for Virus
Pattern and Virus Scan Engine version information to keep its data
current. It then uses a policy you configure to perform a comparison
of this information with the OfficeScan client security
posture data.
-
Following that, the Policy Server creates a posture token,
and passes it back to the OfficeScan client.
-
The OfficeScan client performs
the actions configured in the posture token.
