NAME
       fail2ban_selinux - Security Enhanced Linux Policy for the fail2ban pro‐
       cesses

DESCRIPTION
       Security-Enhanced Linux secures the  fail2ban  processes	 via  flexible
       mandatory access control.

       The  fail2ban  processes	 execute with the fail2ban_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 fail2ban_t

ENTRYPOINTS
       The fail2ban_t SELinux type can be entered via the fail2ban_exec_t file
       type.

       The default entrypoint paths for the fail2ban_t domain are the  follow‐
       ing:

       /usr/bin/fail2ban, /usr/bin/fail2ban-server

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
       fail2ban policy is very flexible allowing users to setup their fail2ban
       processes in as secure a method as possible.

       The following process types are defined for fail2ban:

       fail2ban_client_t, fail2ban_t

       Note: semanage permissive -a fail2ban_t can be used to make the process
       type  fail2ban_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.
       fail2ban policy is extremely flexible and  has  several	booleans  that
       allow  you  to manipulate the policy and run fail2ban 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 fail2ban_client_t,
       fail2ban_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
       fail2ban_client_t,  fail2ban_t,	you  must turn on the kerberos_enabled
       boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The SELinux process type fail2ban_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 fail2ban policy is very flexible allowing users to setup	 their
       fail2ban processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the fail2ban, 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  fail2ban_client_exec_t  '/srv/fail2ban/con‐
       tent(/.*)?'
       restorecon -R -v /srv/myfail2ban_content

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

       The following file types are defined for fail2ban:

       fail2ban_client_exec_t

       - Set files with the fail2ban_client_exec_t type, if you want to	 tran‐
       sition an executable to the fail2ban_client_t domain.

       fail2ban_exec_t

       - Set files with the fail2ban_exec_t type, if you want to transition an
       executable to the fail2ban_t domain.

       Paths:
	    /usr/bin/fail2ban, /usr/bin/fail2ban-server

       fail2ban_initrc_exec_t

       - Set files with the fail2ban_initrc_exec_t type, if you want to	 tran‐
       sition an executable to the fail2ban_initrc_t domain.

       fail2ban_log_t

       - Set files with the fail2ban_log_t type, if you want to treat the data
       as fail2ban log data, usually stored under the /var/log directory.

       fail2ban_tmp_t

       - Set files with the fail2ban_tmp_t type, if you want to store fail2ban
       temporary files in the /tmp directories.

       fail2ban_var_lib_t

       -  Set files with the fail2ban_var_lib_t type, if you want to store the
       fail2ban files under the /var/lib directory.

       fail2ban_var_run_t

       - Set files with the fail2ban_var_run_t type, if you want to store  the
       fail2ban 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.
