6 certmaster_selinux - Security Enhanced Linux Policy for the certmaster
7 processes
8
10 Security-Enhanced Linux secures the certmaster processes via flexible
11 mandatory access control.
12
13 The certmaster processes execute with the certmaster_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep certmaster_t
20
21
22
24 The certmaster_t SELinux type can be entered via the certmaster_exec_t
25 file type.
26
27 The default entrypoint paths for the certmaster_t domain are the fol‐
28 lowing:
29
30 /usr/bin/certmaster
31
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 certmaster policy is very flexible allowing users to setup their cert‐
40 master processes in as secure a method as possible.
41
42 The following process types are defined for certmaster:
43
44 certmaster_t
45
46 Note: semanage permissive -a certmaster_t can be used to make the
47 process type certmaster_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. cert‐
54 master policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run certmaster 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
94
95
97 SELinux defines port types to represent TCP and UDP ports.
98
99 You can see the types associated with a port by using the following
100 command:
101
102 semanage port -l
103
104
105 Policy governs the access confined processes have to these ports.
106 SELinux certmaster policy is very flexible allowing users to setup
107 their certmaster processes in as secure a method as possible.
108
109 The following port types are defined for certmaster:
110
111
112 certmaster_port_t
113
114
115
116 Default Defined Ports:
117 tcp 51235
118
120 The SELinux process type certmaster_t can manage files labeled with the
121 following file types. The paths listed are the default paths for these
122 file types. Note the processes UID still need to have DAC permissions.

189 SELinux requires files to have an extended attribute to define the file
190 type.
191
192 You can see the context of a file using the -Z option to ls
193
194 Policy governs the access confined processes have to these files.
195 SELinux certmaster policy is very flexible allowing users to setup
196 their certmaster processes in as secure a method as possible.
197
198 STANDARD FILE CONTEXT
199
200 SELinux defines the file context types for the certmaster, if you
201 wanted to store files with these types in a diffent paths, you need to
202 execute the semanage command to sepecify alternate labeling and then
203 use restorecon to put the labels on disk.
204
205 semanage fcontext -a -t certmaster_var_run_t '/srv/mycertmaster_con‐
206 tent(/.*)?'
207 restorecon -R -v /srv/mycertmaster_content
208
209 Note: SELinux often uses regular expressions to specify labels that
210 match multiple files.
211
212 The following file types are defined for certmaster:
213
214
215
216 certmaster_etc_rw_t
217
218 - Set files with the certmaster_etc_rw_t type, if you want to treat the
219 files as certmaster etc read/write content.
220
221
222
223 certmaster_exec_t
224
225 - Set files with the certmaster_exec_t type, if you want to transition
226 an executable to the certmaster_t domain.
227
228
229
230 certmaster_initrc_exec_t
231
232 - Set files with the certmaster_initrc_exec_t type, if you want to
233 transition an executable to the certmaster_initrc_t domain.
234
235
236
237 certmaster_var_lib_t
238
239 - Set files with the certmaster_var_lib_t type, if you want to store
240 the certmaster files under the /var/lib directory.
241
242
243
244 certmaster_var_log_t
245
246 - Set files with the certmaster_var_log_t type, if you want to treat
247 the data as certmaster var log data, usually stored under the /var/log
248 directory.
249
250
251
252 certmaster_var_run_t
253
254 - Set files with the certmaster_var_run_t type, if you want to store
255 the certmaster files under the /run or /var/run directory.
256
257
258
259 Note: File context can be temporarily modified with the chcon command.
260 If you want to permanently change the file context you need to use the
261 semanage fcontext command. This will modify the SELinux labeling data‐
262 base. You will need to use restorecon to apply the labels.
263
264
266 semanage fcontext can also be used to manipulate default file context
267 mappings.
268
269 semanage permissive can also be used to manipulate whether or not a
270 process type is permissive.
271
272 semanage module can also be used to enable/disable/install/remove pol‐
273 icy modules.
274
275 semanage port can also be used to manipulate the port definitions
276
277 semanage boolean can also be used to manipulate the booleans
278
279
280 system-config-selinux is a GUI tool available to customize SELinux pol‐
281 icy settings.
