Hi,
Thank you for posting in Symantec community.
I would be glad to answer your query.
SEP for Linux clients can now be managed by RU5 SEPM, or later. Configuration enhancements have been made to the SEPM to allow policy creation for managed Linux clients. This includes AV policy settings, centralized exceptions, and LiveUpdate settings. The SEPM also features enhanced reporting for Linux clients, including the SEP client version, host OS details, and hardware details.
To install SEP on linux I would encourage to go through this article: https://www-secure.symantec.com/connect/articles/how-install-symantec-endpoint-protection-1215-ru5-linux-operating-system
Latest version can be downloaded here
But Linux clients cannot get updates from the default management server. For Linux clients, you must specify an internal or external LiveUpdate server.
To find configuration check this thread: https://www-secure.symantec.com/connect/forums/lua-linux-definitions#comment-10744651
