AUDIT2ALLOW(1)                        NSA                       AUDIT2ALLOW(1)



NAME
       audit2allow - generate policy allow rules from logs of denied operations

SYNOPSIS
       audit2allow [options]

OPTIONS
       --help Print a short usage message

       -d     Read  input  from  output  of  /bin/dmesg.  Note that audit messages are not
              available via dmesg when auditd is running; use -i  /var/log/audit/audit.log
              instead.

       -v     Turn on verbose output

       -l     read input only after last policy reload

       -i <inputfile>
              read input from <inputfile>

       -o <outputfile>
              append output to <outputfile>

DESCRIPTION
       This  utility  scans the logs for messages logged when the system denied permission
       for operations, and generates a snippet of policy rules which, if loaded into  pol-
       icy,  might  have  allowed  those operations to succeed. However, this utility only
       generates Type Enforcement  (TE)  allow  rules.   Certain  permission  denials  may
       require  other kinds of policy changes, e.g. adding an attribute to a type declara-
       tion to satisfy an existing constraint, adding a role allow rule,  or  modifying  a
       constraint.  The audit2why(8) utility may be used to diagnose the reason when it is
       unclear.

       Care must be exercised while acting on the output of this utility  to  ensure  that
       the operations being permitted do not pose a security threat. Often it is better to
       define new domains and/or types, or make other structural changes to narrowly allow
       an  optimal  set  of  operations to succeed, as opposed to blindly implementing the
       sometimes broad changes recommended by this utility.   Certain  permission  denials
       are not fatal to the application, in which case it may be preferable to simply sup-
       press logging of the denial via a ’dontaudit’ rule rather than an ’allow’ rule.


EXAMPLE
       $ cd /etc/selinux/$(SELINUXTYPE)/src/policy
       $ /usr/bin/audit2allow -i < /var/log/audit/audit.log >> domains/misc/local.te
       <review domains/misc/local.te and customize as desired>
       $ make load
