NAME

6       fail2ban_selinux - Security Enhanced Linux Policy for the fail2ban pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  fail2ban  processes  via  flexible
11       mandatory access control.
12
13       The  fail2ban  processes  execute with the fail2ban_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep fail2ban_t
20
21
22

ENTRYPOINTS

24       The fail2ban_t SELinux type can be entered via the fail2ban_exec_t file
25       type.
26
27       The default entrypoint paths for the fail2ban_t domain are the  follow‐
28       ing:
29
30       /usr/bin/fail2ban, /usr/bin/fail2ban-server
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       fail2ban policy is very flexible allowing users to setup their fail2ban
40       processes in as secure a method as possible.
41
42       The following process types are defined for fail2ban:
43
44       fail2ban_t, fail2ban_client_t
45
46       Note: semanage permissive -a fail2ban_t can be used to make the process
47       type  fail2ban_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       fail2ban policy is extremely flexible and  has  several  booleans  that
55       allow  you  to manipulate the policy and run fail2ban with the tightest
56       access possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Enabled by default.
91
92       setsebool -P nscd_use_shm 1
93

95

MANAGED FILES

97       The SELinux process type fail2ban_t can manage files labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

169       SELinux requires files to have an extended attribute to define the file
170       type.
171
172       You can see the context of a file using the -Z option to ls
173
174       Policy  governs  the  access  confined  processes  have to these files.
175       SELinux fail2ban policy is very flexible allowing users to setup  their
176       fail2ban processes in as secure a method as possible.
177
178       STANDARD FILE CONTEXT
179
180       SELinux  defines the file context types for the fail2ban, if you wanted
181       to store files with these types in a diffent paths, you need to execute
182       the  semanage  command  to  sepecify  alternate  labeling  and then use
183       restorecon to put the labels on disk.
184
185       semanage fcontext -a -t fail2ban_tmp_t '/srv/myfail2ban_content(/.*)?'
186       restorecon -R -v /srv/myfail2ban_content
187
188       Note: SELinux often uses regular expressions  to  specify  labels  that
189       match multiple files.
190
191       The following file types are defined for fail2ban:
192
193
194
195       fail2ban_client_exec_t
196
197       -  Set files with the fail2ban_client_exec_t type, if you want to tran‐
198       sition an executable to the fail2ban_client_t domain.
199
200
201
202       fail2ban_exec_t
203
204       - Set files with the fail2ban_exec_t type, if you want to transition an
205       executable to the fail2ban_t domain.
206
207
208       Paths:
209            /usr/bin/fail2ban, /usr/bin/fail2ban-server
210
211
212       fail2ban_initrc_exec_t
213
214       -  Set files with the fail2ban_initrc_exec_t type, if you want to tran‐
215       sition an executable to the fail2ban_initrc_t domain.
216
217
218
219       fail2ban_log_t
220
221       - Set files with the fail2ban_log_t type, if you want to treat the data
222       as fail2ban log data, usually stored under the /var/log directory.
223
224
225
226       fail2ban_tmp_t
227
228       - Set files with the fail2ban_tmp_t type, if you want to store fail2ban
229       temporary files in the /tmp directories.
230
231
232
233       fail2ban_var_lib_t
234
235       - Set files with the fail2ban_var_lib_t type, if you want to store  the
236       fail2ban files under the /var/lib directory.
237
238
239
240       fail2ban_var_run_t
241
242       -  Set files with the fail2ban_var_run_t type, if you want to store the
243       fail2ban files under the /run or /var/run directory.
244
245
246
247       Note: File context can be temporarily modified with the chcon  command.
248       If  you want to permanently change the file context you need to use the
249       semanage fcontext command.  This will modify the SELinux labeling data‐
250       base.  You will need to use restorecon to apply the labels.
251
252

COMMANDS

254       semanage  fcontext  can also be used to manipulate default file context
255       mappings.
256
257       semanage permissive can also be used to manipulate  whether  or  not  a
258       process type is permissive.
259
260       semanage  module can also be used to enable/disable/install/remove pol‐
261       icy modules.
262
263       semanage boolean can also be used to manipulate the booleans
264
265
266       system-config-selinux is a GUI tool available to customize SELinux pol‐
267       icy settings.
