How to set Solaris 8 adminstrative settings?

Hi Experts,

       I am new to Solaris 8 and need help on a few outstanding issues on administrative settings:
1. The audit file located in drwxr-xr-x 3 root root 512 Sep 11 09:27 /security1  and audit file  drwxr-xr-x 3 root root 512 Sep 7 09:09 /security2 needs to be locked down to only admins.

2. Ensure access to exported filesystems is restricted to local hosts via the export config file. Files /etc/exports and /etc/dfs/dfstab need to be protected against unauthorized modifications.  The two file systems will be owned by root and will not beworld or group writable.

3. Use nosuid and nosgif option to mount filesystems from a server to prevent setuid and setguid executables of dubious origin from gaining root access on the client system.

Also, any suggestions on web sites or books on learning Solaris 8?

Thank You, Missymadi
