Based on that location, the Endpoint Security Client does the following: Implements policy-based filtering for all incoming and outgoing network traffic. Implements policy-based control over hardware use (such as WLAN network adapters’ ad hocconnections). Launches nominated applications in policy-defined situations (for example, if a policy is set torequire a VPN program in order to access the network, that program is launched).If the network environment is not recognized, the Endpoint Security Client sets the location to adefault Unknown location, and applies the Unknown security policy. Security policies arecompletely configurable by the Endpoint Security Management Administrator. For EndpointSecurity Client operating instructions, see the ZENworks Endpoint Security Client 3.5 User Guideand ZENworks Endpoint Security Client 4.0 User Guide.All Endpoint Security Client security functionality is determined by the security policy.
