NAME
       apcupsd_selinux	-  Security Enhanced Linux Policy for the apcupsd pro‐
       cesses

DESCRIPTION
       Security-Enhanced Linux secures	the  apcupsd  processes	 via  flexible
       mandatory access control.

       The  apcupsd processes execute with the apcupsd_t SELinux type. You can
       check if you have these processes running by executing the  ps  command
       with the -Z qualifier.

       For example:

       ps -eZ | grep apcupsd_t

ENTRYPOINTS
       The  apcupsd_t  SELinux type can be entered via the apcupsd_exec_t file
       type.

       The default entrypoint paths for the apcupsd_t domain are  the  follow‐
       ing:

       /sbin/apcupsd, /usr/sbin/apcupsd

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have  to  files.   SELinux
       apcupsd	policy	is very flexible allowing users to setup their apcupsd
       processes in as secure a method as possible.

       The following process types are defined for apcupsd:

       apcupsd_t

       Note: semanage permissive -a apcupsd_t can be used to make the  process
       type  apcupsd_t	permissive. SELinux does not deny access to permissive
       process types, but the AVC (SELinux denials) messages are still	gener‐
       ated.

BOOLEANS
       SELinux policy is customizable based on least access required.  apcupsd
       policy is extremely flexible and has several booleans that allow you to
       manipulate  the	policy and run apcupsd with the tightest access possi‐
       ble.

       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons to write corefiles to /, you must turn
       on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If  you	want  to enable cluster mode for daemons, you must turn on the
       daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn  on
       the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If  you	want to allow all daemons the ability to read/write terminals,
       you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn
       on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If  you	want  to allow confined applications to run with kerberos, you
       must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with	NIS,  you  must	 turn  on  the
       nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If  you	want to allow confined applications to use nscd shared memory,
       you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then using a sssd server for the apcupsd_t, you must turn
       on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the
       apcupsd_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

PORT TYPES
       SELinux defines port types to represent TCP and UDP ports.

       You  can	 see  the  types associated with a port by using the following
       command:

       semanage port -l

       Policy governs the access  confined  processes  have  to	 these	ports.
       SELinux	apcupsd	 policy is very flexible allowing users to setup their
       apcupsd processes in as secure a method as possible.

       The following port types are defined for apcupsd:

       apcupsd_port_t

       Default Defined Ports:
		 tcp 3551
		 udp 3551

MANAGED FILES
       The SELinux process type apcupsd_t can manage files  labeled  with  the
       following file types.  The paths listed are the default paths for these
       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy  governs	the  access  confined  processes  have to these files.
       SELinux apcupsd policy is very flexible allowing users to  setup	 their
       apcupsd processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines	 the file context types for the apcupsd, if you wanted
       to store files with these types in a diffent paths, you need to execute
       the  semanage  command  to  sepecify  alternate	labeling  and then use
       restorecon to put the labels on disk.

       semanage fcontext -a -t apcupsd_exec_t '/srv/apcupsd/content(/.*)?'
       restorecon -R -v /srv/myapcupsd_content

       Note: SELinux often uses regular expressions  to	 specify  labels  that
       match multiple files.

       The following file types are defined for apcupsd:

       apcupsd_exec_t

       -  Set files with the apcupsd_exec_t type, if you want to transition an
       executable to the apcupsd_t domain.

       Paths:
	    /sbin/apcupsd, /usr/sbin/apcupsd

       apcupsd_initrc_exec_t

       - Set files with the apcupsd_initrc_exec_t type, if you want to transi‐
       tion an executable to the apcupsd_initrc_t domain.

       apcupsd_lock_t

       -  Set  files  with  the	 apcupsd_lock_t type, if you want to treat the
       files as apcupsd lock data, stored under the /var/lock directory

       Paths:
	    /var/lock/LCK.., /var/lock/subsys/apcupsd

       apcupsd_log_t

       - Set files with the apcupsd_log_t type, if you want to treat the  data
       as apcupsd log data, usually stored under the /var/log directory.

       Paths:
	    /var/log/apcupsd.events.*, /var/log/apcupsd.status.*

       apcupsd_power_t

       -  Set  files  with  the apcupsd_power_t type, if you want to treat the
       files as apcupsd power data.

       apcupsd_tmp_t

       - Set files with the apcupsd_tmp_t type, if you want to	store  apcupsd
       temporary files in the /tmp directories.

       apcupsd_unit_file_t

       - Set files with the apcupsd_unit_file_t type, if you want to treat the
       files as apcupsd unit content.

       apcupsd_var_run_t

       - Set files with the apcupsd_var_run_t type, if you want to  store  the
       apcupsd files under the /run or /var/run directory.

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanently change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

COMMANDS
       semanage fcontext can also be used to manipulate default	 file  context
       mappings.

       semanage	 permissive  can  also	be used to manipulate whether or not a
       process type is permissive.

       semanage module can also be used to enable/disable/install/remove  pol‐
       icy modules.

       semanage port can also be used to manipulate the port definitions

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
