6 syslogd_selinux - Security Enhanced Linux Policy for the syslogd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the syslogd processes via flexible
11 mandatory access control.
12
13 The syslogd processes execute with the syslogd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep syslogd_t
20
21
22
24 The syslogd_t SELinux type can be entered via the syslogd_exec_t file
25 type.
26
27 The default entrypoint paths for the syslogd_t domain are the follow‐
28 ing:
29
30 /sbin/syslogd, /sbin/minilogd, /sbin/rsyslogd, /sbin/syslog-ng,
31 /usr/sbin/metalog, /usr/sbin/syslogd, /usr/sbin/minilogd,
32 /usr/sbin/rsyslogd, /usr/sbin/syslog-ng, /usr/lib/systemd/systemd-jour‐
33 nald, /usr/lib/systemd/systemd-kmsg-syslogd
34
36 SELinux defines process types (domains) for each process running on the
37 system
38
39 You can see the context of a process using the -Z option to ps
40
41 Policy governs the access confined processes have to files. SELinux
42 syslogd policy is very flexible allowing users to setup their syslogd
43 processes in as secure a method as possible.
44
45 The following process types are defined for syslogd:
46
47 syslogd_t
48
49 Note: semanage permissive -a syslogd_t can be used to make the process
50 type syslogd_t permissive. SELinux does not deny access to permissive
51 process types, but the AVC (SELinux denials) messages are still gener‐
52 ated.
53
54
56 SELinux policy is customizable based on least access required. syslogd
57 policy is extremely flexible and has several booleans that allow you to
58 manipulate the policy and run syslogd with the tightest access possi‐
59 ble.
60
61
62
63 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65
66 setsebool -P fips_mode 1
67
68
69
70 If you want to allow confined applications to run with kerberos, you
71 must turn on the kerberos_enabled boolean. Enabled by default.
72
73 setsebool -P kerberos_enabled 1
74
75
76
77 If you want to allow syslogd daemon append public content files, you
78 must turn on the logging_syslogd_append_public_content boolean. Dis‐
79 abled by default.
80
81 setsebool -P logging_syslogd_append_public_content 1
82
83
84
85 If you want to allow syslogd daemon to send mail, you must turn on the
86 logging_syslogd_can_sendmail boolean. Disabled by default.
87
88 setsebool -P logging_syslogd_can_sendmail 1
89
90
91
92 If you want to allow syslogd daemon list non security directories, you
93 must turn on the logging_syslogd_list_non_security_dirs boolean. Dis‐
94 abled by default.
95
96 setsebool -P logging_syslogd_list_non_security_dirs 1
97
98
99
100 If you want to allow syslogd the ability to call nagios plugins. It is
101 turned on by omprog rsyslog plugin, you must turn on the logging_sys‐
102 logd_run_nagios_plugins boolean. Disabled by default.
103
104 setsebool -P logging_syslogd_run_nagios_plugins 1
105
106
107
108 If you want to allow syslogd the ability to read/write terminals, you
109 must turn on the logging_syslogd_use_tty boolean. Enabled by default.
110
111 setsebool -P logging_syslogd_use_tty 1
112
113
114
116 SELinux defines port types to represent TCP and UDP ports.
117
118 You can see the types associated with a port by using the following
119 command:
120
121 semanage port -l
122
123
124 Policy governs the access confined processes have to these ports.
125 SELinux syslogd policy is very flexible allowing users to setup their
126 syslogd processes in as secure a method as possible.
127
128 The following port types are defined for syslogd:
129
130
131 syslog_tls_port_t
132
133
134
135 Default Defined Ports:
136 tcp 6514,10514
137 udp 6514,10514
138
139
140 syslogd_port_t
141
142
143
144 Default Defined Ports:
145 tcp 601,20514
146 udp 514,601,20514
147
149 The SELinux process type syslogd_t can manage files labeled with the
150 following file types. The paths listed are the default paths for these
151 file types. Note the processes UID still need to have DAC permissions.

241 SELinux requires files to have an extended attribute to define the file
242 type.
243
244 You can see the context of a file using the -Z option to ls
245
246 Policy governs the access confined processes have to these files.
247 SELinux syslogd policy is very flexible allowing users to setup their
248 syslogd processes in as secure a method as possible.
249
250 EQUIVALENCE DIRECTORIES
251
252
253 syslogd policy stores data with multiple different file context types
254 under the /var/lib/syslog-ng directory. If you would like to store the
255 data in a different directory you can use the semanage command to cre‐
256 ate an equivalence mapping. If you wanted to store this data under the
257 /srv directory you would execute the following command:
258
259 semanage fcontext -a -e /var/lib/syslog-ng /srv/syslog-ng
260 restorecon -R -v /srv/syslog-ng
261
262 syslogd policy stores data with multiple different file context types
263 under the /var/run/syslog-ng directory. If you would like to store the
264 data in a different directory you can use the semanage command to cre‐
265 ate an equivalence mapping. If you wanted to store this data under the
266 /srv directory you would execute the following command:
267
268 semanage fcontext -a -e /var/run/syslog-ng /srv/syslog-ng
269 restorecon -R -v /srv/syslog-ng
270
271 STANDARD FILE CONTEXT
272
273 SELinux defines the file context types for the syslogd, if you wanted
274 to store files with these types in a diffent paths, you need to execute
275 the semanage command to specify alternate labeling and then use re‐
276 storecon to put the labels on disk.
277
278 semanage fcontext -a -t syslogd_unit_file_t '/srv/mysyslogd_con‐
279 tent(/.*)?'
280 restorecon -R -v /srv/mysyslogd_content
281
282 Note: SELinux often uses regular expressions to specify labels that
283 match multiple files.
284
285 The following file types are defined for syslogd:
286
287
288
289 syslogd_exec_t
290
291 - Set files with the syslogd_exec_t type, if you want to transition an
292 executable to the syslogd_t domain.
293
294
295 Paths:
296 /sbin/syslogd, /sbin/minilogd, /sbin/rsyslogd, /sbin/syslog-ng,
297 /usr/sbin/metalog, /usr/sbin/syslogd, /usr/sbin/minilogd,
298 /usr/sbin/rsyslogd, /usr/sbin/syslog-ng, /usr/lib/systemd/systemd-
299 journald, /usr/lib/systemd/systemd-kmsg-syslogd
300
301
302 syslogd_initrc_exec_t
303
304 - Set files with the syslogd_initrc_exec_t type, if you want to transi‐
305 tion an executable to the syslogd_initrc_t domain.
306
307
308
309 syslogd_tmp_t
310
311 - Set files with the syslogd_tmp_t type, if you want to store syslogd
312 temporary files in the /tmp directories.
313
314
315
316 syslogd_tmpfs_t
317
318 - Set files with the syslogd_tmpfs_t type, if you want to store syslogd
319 files on a tmpfs file system.
320
321
322
323 syslogd_unit_file_t
324
325 - Set files with the syslogd_unit_file_t type, if you want to treat the
326 files as syslogd unit content.
327
328
329
330 syslogd_var_lib_t
331
332 - Set files with the syslogd_var_lib_t type, if you want to store the
333 syslogd files under the /var/lib directory.
334
335
336 Paths:
337 /var/lib/r?syslog(/.*)?, /var/lib/syslog-ng(/.*)?, /var/lib/sys‐
338 log-ng.persist, /var/lib/misc/syslog-ng.persist-?
339
340
341 syslogd_var_run_t
342
343 - Set files with the syslogd_var_run_t type, if you want to store the
344 syslogd files under the /run or /var/run directory.
345
346
347 Paths:
348 /var/run/log(/.*)?, /var/run/syslog-ng.ctl, /var/run/syslog-
349 ng(/.*)?, /var/run/systemd/journal(/.*)?, /var/run/metalog.pid,
350 /var/run/syslogd.pid
351
352
353 Note: File context can be temporarily modified with the chcon command.
354 If you want to permanently change the file context you need to use the
355 semanage fcontext command. This will modify the SELinux labeling data‐
356 base. You will need to use restorecon to apply the labels.
357
358
360 semanage fcontext can also be used to manipulate default file context
361 mappings.
362
363 semanage permissive can also be used to manipulate whether or not a
364 process type is permissive.
365
366 semanage module can also be used to enable/disable/install/remove pol‐
367 icy modules.
368
369 semanage port can also be used to manipulate the port definitions
370
371 semanage boolean can also be used to manipulate the booleans
372
373
374 system-config-selinux is a GUI tool available to customize SELinux pol‐
375 icy settings.
