##################################################################### # # SOLARIS Configuration file for samhain. # # Based on a contribution by Sean Boran (sean [at] boran d.o.t com) # # HISTORY: # 16.Aug.03 rw add plenty of comments # 24.Jun.02 rw remove linux stuff, clean up a bit # 06.Jun.02 sb <3>, add LOTS more Solaris stuff. Also and comment at bottom # of this file. # 03.Jun.02 sb Separate Linux & Solaris # 24.Apr.02 sb Use Samhain v.15 template and tune for Solaris. # # To do: logs /var/adm/messages and /var/cron/log are # pruned weekly. ##################################################################### # # -- empty lines and lines starting with '#', ';' or '//' are ignored # -- boolean options can be Yes/No or True/False or 1/0 # -- you can PGP clearsign this file -- samhain will check (if compiled # with support) or otherwise ignore the signature # -- CHECK mail address # # To each log facility, you can assign a threshold severity. Only # reports with at least the threshold severity will be logged # to the respective facility (even further below). # ##################################################################### # SETUP for file system checking: # (i) There are several policies, each has its own section. Put files # into the section for the appropriate policy (see below). # (ii) Section [EventSeverity]: # To each policy, you can assign a severity (further below). # (iii) Section [Log]: # To each log facility, you can assign a threshold severity. Only # reports with at least the threshold severity will be logged # to the respective facility (even further below). ##################################################################### ##################################################################### # # Files are defined with: file = /absolute/path # # Directories are defined with: dir = /absolute/path # or with an optional recursion depth (N <= 99): dir = N/absolute/path # # Directory inodes are checked.
