There is no security without physical security.
Glad it worked out.

mac_bsdextended
MAC_BSDEXTENDED(4) BSD Kernel Interfaces Manual MAC_BSDEXTENDED(4)
NAME
mac_bsdextended -- file system firewall policy
SYNOPSIS
To compile the file system firewall policy into your kernel, place the following lines in your kernel configuration file:
options MAC
options MAC_BSDEXTENDED
Alternately, to load the file system firewall policy module at boot time, place the following line in your kernel configuration file:
options MAC
and in loader.conf(5):
mac_bsdextended_load="YES"
DESCRIPTION
The mac_bsdextended security policy module provides an interface for the system administrator to impose mandatory rules regarding users and
some system objects. Rules are uploaded to the module (typically using ugidfw(8), or some other tool utilizing libugidfw(3)) where they are
stored internally and used to determine whether to allow or deny specific accesses (see ugidfw(8)).
IMPLEMENTATION NOTES
While the traditional mac(9) entry points are implemented, policy labels are not used; instead, access control decisions are made by iterat-
ing through the internal list of rules until a rule which denies the particular access is found, or the end of the list is reached. The
mac_bsdextended policy works similar to ipfw(8) or by using a first match semantic. This means that not all rules are applied, only the
first matched rule; thus if Rule A allows access and Rule B blocks access, Rule B will never be applied.
Sysctls
The following sysctls may be used to tweak the behavior of mac_bsdextended:
security.mac.bsdextended.enabled
Set to zero or one to toggle the policy off or on.
security.mac.bsdextended.rule_count
List the number of defined rules, the maximum rule count is current set at 256.
security.mac.bsdextended.rule_slots
List the number of rule slots currently being used.
security.mac.bsdextended.firstmatch_enabled
Toggle between the old all rules match functionality and the new first rule matches functionality. This is enabled by default.
security.mac.bsdextended.logging
Log all access violations via the AUTHPRIV syslog(3) facility.
security.mac.bsdextended.rules
Currently does nothing interesting.

HISTORY
The mac_bsdextended policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project.
The "match first case" and logging capabilities were later added by Tom Rhodes <trhodes@FreeBSD.org>.
