NAME

6       redis_selinux - Security Enhanced Linux Policy for the redis processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The redis_t SELinux type can be entered via the redis_exec_t file type.
24
25       The default entrypoint paths for the redis_t domain are the following:
26
27       /var/opt/rh/rh-redis32/redis(/.*)?, /usr/bin/redis-server
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       redis policy is very flexible allowing users to setup their redis  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for redis:
40
41       redis_t
42
43       Note:  semanage  permissive  -a redis_t can be used to make the process
44       type redis_t permissive. SELinux does not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least access  required.   redis
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run redis with the tightest access possible.
53
54
55
56       If you want to allow Redis to run redis-sentinal notification  scripts,

91       If  you  want  to deny any process from ptracing or debugging any other
92       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
93       default.
94
95       setsebool -P deny_ptrace 1
96
97
98
99       If  you  want  to  allow  any  process  to mmap any file on system with
100       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
101       ean. Enabled by default.

106
107       If  you want to allow all domains write to kmsg_device, while kernel is
108       executed with systemd.log_target=kmsg parameter, you must turn  on  the

PORT TYPES

152       SELinux defines port types to represent TCP and UDP ports.
153
154       You  can  see  the  types associated with a port by using the following
155       command:
156
157       semanage port -l
158
159
160       Policy governs the access  confined  processes  have  to  these  ports.
161       SELinux  redis  policy  is  very flexible allowing users to setup their
162       redis processes in as secure a method as possible.
163
164       The following port types are defined for redis:
165
166
167       redis_port_t
168
169
170
171       Default Defined Ports:
172                 tcp 6379,16379,26379
173

MANAGED FILES

175       The SELinux process type redis_t can manage files labeled with the fol‐
176       lowing  file  types.   The paths listed are the default paths for these
177       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

232       SELinux requires files to have an extended attribute to define the file
233       type.
234
235       You can see the context of a file using the -Z option to ls
236
237       Policy  governs  the  access  confined  processes  have to these files.
238       SELinux redis policy is very flexible allowing  users  to  setup  their
239       redis processes in as secure a method as possible.
240
241       STANDARD FILE CONTEXT
242
243       SELinux  defines the file context types for the redis, if you wanted to
244       store files with these types in a diffent paths, you  need  to  execute
245       the  semanage  command  to  sepecify  alternate  labeling  and then use
246       restorecon to put the labels on disk.
247
248       semanage fcontext -a -t redis_var_run_t '/srv/myredis_content(/.*)?'
249       restorecon -R -v /srv/myredis_content
250
251       Note: SELinux often uses regular expressions  to  specify  labels  that
252       match multiple files.
253
254       The following file types are defined for redis:
255
256
257
258       redis_conf_t
259
260       -  Set files with the redis_conf_t type, if you want to treat the files
261       as redis configuration data, usually stored under the /etc directory.
262
263
264
265       redis_exec_t
266
267       - Set files with the redis_exec_t type, if you want  to  transition  an
268       executable to the redis_t domain.
269
270
271       Paths:
272            /var/opt/rh/rh-redis32/redis(/.*)?, /usr/bin/redis-server
273
274
275       redis_initrc_exec_t
276
277       -  Set  files with the redis_initrc_exec_t type, if you want to transi‐
278       tion an executable to the redis_initrc_t domain.
279
280
281
282       redis_log_t
283
284       - Set files with the redis_log_t type, if you want to treat the data as
285       redis log data, usually stored under the /var/log directory.
286
287
288
289       redis_unit_file_t
290
291       -  Set  files with the redis_unit_file_t type, if you want to treat the
292       files as redis unit content.
293
294
295
296       redis_var_lib_t
297
298       - Set files with the redis_var_lib_t type, if you  want  to  store  the
299       redis files under the /var/lib directory.
300
301
302
303       redis_var_run_t
304
305       -  Set  files  with  the redis_var_run_t type, if you want to store the
306       redis files under the /run or /var/run directory.
307
308
309
310       Note: File context can be temporarily modified with the chcon  command.
311       If  you want to permanently change the file context you need to use the
312       semanage fcontext command.  This will modify the SELinux labeling data‐
313       base.  You will need to use restorecon to apply the labels.
314
315

COMMANDS

317       semanage  fcontext  can also be used to manipulate default file context
318       mappings.
319
320       semanage permissive can also be used to manipulate  whether  or  not  a
321       process type is permissive.
322
323       semanage  module can also be used to enable/disable/install/remove pol‐
324       icy modules.
325
326       semanage port can also be used to manipulate the port definitions
327
328       semanage boolean can also be used to manipulate the booleans
329
330
331       system-config-selinux is a GUI tool available to customize SELinux pol‐
332       icy settings.
