Location Awareness
Protecting Computers from Web-based Threats
In many organizations, employees use both desktop and notebook computers to
perform their tasks. Since notebook computers connect to multiple networks and
employees physically carry them past the organization's premises, OfficeScan needs to
extend protection to these computers when they disconnect from the network. Web
Reputation Policies ensure client computers are protected regardless of location.
A client's location ("internal" or "external") dictates the policy applied to the computer.
You need to specify whether location is based on the client computer's gateway IP
address or the client's connection status with the OfficeScan server or any reference
server.
To configure location awareness settings, see Computer Location on page 9-2.
Web Reputation Policies
Web reputation policies dictate whether OfficeScan will block or allow access to a Web
site. To determine the appropriate policy to use, OfficeScan checks the client's location.
Location is based on either the client computer's gateway IP address or the client's
connection status with the OfficeScan server or any reference server.
A client's location is "internal" if:
• The client’s gateway IP address matches any of the gateway IP addresses specified
on the Computer Location screen
• If the client can connect to the OfficeScan server or any of the reference servers.
Otherwise, a client's location is "external".
