Virtualization - Novell LINUX ENTERPRISE DESKTOP 10 SP2 - DEPLOYMENT GUIDE 08-05-2008 Deployment Manual

If you select Nobody, any user can find only the paths in the database that can be
seen by any other (unprivileged) user. If root is selected, all local files are indexed,
because the user root, as superuser, may access all directories. Make sure that
the options Current Directory in root's Path and Current Directory in Path of
Regular Users are deactivated. Only advanced users should consider using these
options because these settings may pose a significant security risk if used incorrectly.
To have some control over the system even if it crashes, click Enable Magic SysRq
Keys.
Click Finish to complete your security configuration.

it with Security and Users > Firewall. Find detailed information about SuSEfirewall2

network interface. Start this module only if you want to reconfigure the firewall
with custom settings or deactivate it.
