Novell ZENworks Endpoint Security Management 3.5 Manuale Utente

ZENworks® ESM 3.5

Administrator’s Manual

The Client Location Assurance Service 
(CLAS) is an optional feature that provides a 
cryptographically-hardened verification that a 
pre-defined network environment, identified 
by the ZENworks Security Client's location 
verification process, is correct. This service is 
only reliable in network environments that are 
completely and exclusively under the control 
of the ESM Administrator. CLAS should 
always be installed behind the enterprise 
firewall, yet be accessible to any endpoint.

The ZENworks Security Client uses a fixed port to send a challenge to CLAS. CLAS decrypts the 
packet and responds to the challenge, proving that it has the private key matching the public key 
forming the heart of the digital certificate.

Please refer to the Installation and Quick Start guide for selection and installation instructions.

It is recommended that regular Disk Cleanup tasks be configured to run on this server to remove 
temporary files out of the Windows\temp folder.  Under extreme load conditions windows can 
generate an inordinate amount of temporary files that needlessly take up disk space.

The CLAS software can be upgraded by running the new installation software.

To uninstall CLAS, use the Add/Remove Programs function in the Windows Control Panel.
