NAME
       arpwatch_selinux - Security Enhanced Linux Policy for the arpwatch pro‐
       cesses

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

       The  arpwatch  processes	 execute with the arpwatch_t SELinux type. You
       can check if you have these processes running by executing the ps  com‐
       mand with the -Z qualifier.

       For example:

       ps -eZ | grep arpwatch_t

ENTRYPOINTS
       The arpwatch_t SELinux type can be entered via the arpwatch_exec_t file
       type.

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

       /usr/sbin/arpwatch

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
       arpwatch policy is very flexible allowing users to setup their arpwatch
       processes in as secure a method as possible.

       The following process types are defined for arpwatch:

       arpwatch_t

       Note: semanage permissive -a arpwatch_t can be used to make the process
       type  arpwatch_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.  arp‐
       watch policy is extremely flexible and has several booleans that	 allow
       you  to manipulate the policy and run arpwatch with the tightest access
       possible.

       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 arpwatch_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
       arpwatch_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The  SELinux  process type arpwatch_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.

       arpwatch_data_t

	    /var/arpwatch(/.*)?
	    /var/lib/arpwatch(/.*)?

       arpwatch_tmp_t

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	arpwatch policy is very flexible allowing users to setup their
       arpwatch processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the arpwatch, 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 arpwatch_data_t '/srv/arpwatch/content(/.*)?'
       restorecon -R -v /srv/myarpwatch_content

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

       The following file types are defined for arpwatch:

       arpwatch_data_t

       - Set files with the arpwatch_data_t type, if you  want	to  treat  the
       files as arpwatch content.

       Paths:
	    /var/arpwatch(/.*)?, /var/lib/arpwatch(/.*)?

       arpwatch_exec_t

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

       arpwatch_initrc_exec_t

       - Set files with the arpwatch_initrc_exec_t type, if you want to	 tran‐
       sition an executable to the arpwatch_initrc_t domain.

       arpwatch_tmp_t

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

       arpwatch_unit_file_t

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

       arpwatch_var_run_t

       -  Set files with the arpwatch_var_run_t type, if you want to store the
       arpwatch 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 boolean can also be used to manipulate the booleans

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