# # Policy file for FreeBSD # # $FreeBSD$ # This file originally was repocopied from: ports/security/tripwire/files/twpol.txt,v 1.3 2005/08/09 18:24:15 cy Exp # # This is the example Tripwire Policy file. It is intended as a place to # start creating your own custom Tripwire Policy file. Referring to it as # well as the Tripwire Policy Guide should give you enough information to # make a good custom Tripwire Policy file that better covers your # configuration and security needs. A text version of this policy file is # called twpol.txt. # # Note that this file is tuned to an install of FreeBSD using # buildworld. If run unmodified, this file should create no errors on # database creation, or violations on a subsiquent integrity check. # However it is impossible for there to be one policy file for all machines, # so this existing one errs on the side of security. Your FreeBSD # configuration will most likey differ from the one our policy file was # tuned to, and will therefore require some editing of the default # Tripwire Policy file. # # The example policy file is best run with 'Loose Directory Checking' # enabled. Set LOOSEDIRECTORYCHECKING=TRUE in the Tripwire Configuration # file. # # Email support is not included and must be added to this file. # Add the 'emailto=' to the rule directive section of each rule (add a comma # after the 'severity=' line and add an 'emailto=' and include the email # addresses you want the violation reports to go to). Addresses are # semi-colon delimited. # # # Global Variable Definitions # # These are defined at install time by the installation script. You may # Manually edit these if you are using this file directly and not from the # installation script itself. # @@section GLOBAL TWROOT=; TWBIN=; TWPOL=; TWDB=; TWSKEY=; TWLKEY=; TWREPORT=; HOSTNAME=; @@section FS SEC_CRIT = $(IgnoreNone)-SHa ; # Critical files that cannot change SEC_SUID = $(IgnoreNone)-SHa ; # Binaries with the SUID or SGID flags set SEC_BIN = $(ReadOnly) ; # Binaries that should not change SEC_CONFIG = $(Dynamic) ; # Config files that are changed infrequently but accessed often SEC_TTY = $(Dynamic)-ugp ; # Tty files that change ownership at login SEC_LOG = $(Growing) ; # Files that grow, but that should never change ownership SEC_INVARIANT = +tpug ; # Directories that should never change permission or ownership SIG_LOW = 33 ; # Non-critical files that are of minimal security impact SIG_MED = 66 ; # Non-critical files that are of significant security impact SIG_HI = 100 ; # Critical files that are significant points of vulnerability # Tripwire Binaries ( rulename = "Tripwire Binaries", severity = $(SIG_HI) ) { $(TWBIN)/siggen -> $(SEC_BIN) ; $(TWBIN)/tripwire -> $(SEC_BIN) ; $(TWBIN)/twadmin -> $(SEC_BIN) ; $(TWBIN)/twprint -> $(SEC_BIN) ; } # Tripwire Data Files - Configuration Files, Policy Files, Keys, Reports, Databases ( rulename = "Tripwire Data Files", severity = $(SIG_HI) ) { # NOTE: We remove the inode attribute because when Tripwire creates a backup, # it does so by renaming the old file and creating a new one (which will # have a new inode number).
