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 ac‐
56 cess possible.
57
58
59
60 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63
64 setsebool -P daemons_dontaudit_scheduling 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 system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77
78 setsebool -P nis_enabled 1
79
80
81
83 SELinux defines port types to represent TCP and UDP ports.
84
85 You can see the types associated with a port by using the following
86 command:
87
88 semanage port -l
89
90
91 Policy governs the access confined processes have to these ports.
92 SELinux certmaster policy is very flexible allowing users to setup
93 their certmaster processes in as secure a method as possible.
94
95 The following port types are defined for certmaster:
96
97
98 certmaster_port_t
99
100
101
102 Default Defined Ports:
103 tcp 51235
104
106 The SELinux process type certmaster_t can manage files labeled with the
107 following file types. The paths listed are the default paths for these
108 file types. Note the processes UID still need to have DAC permissions.

174 SELinux requires files to have an extended attribute to define the file
175 type.
176
177 You can see the context of a file using the -Z option to ls
178
179 Policy governs the access confined processes have to these files.
180 SELinux certmaster policy is very flexible allowing users to setup
181 their certmaster processes in as secure a method as possible.
182
183 STANDARD FILE CONTEXT
184
185 SELinux defines the file context types for the certmaster, if you
186 wanted to store files with these types in a different paths, you need
187 to execute the semanage command to specify alternate labeling and then
188 use restorecon to put the labels on disk.
189
190 semanage fcontext -a -t certmaster_exec_t '/srv/certmaster/con‐
191 tent(/.*)?'
192 restorecon -R -v /srv/mycertmaster_content
193
194 Note: SELinux often uses regular expressions to specify labels that
195 match multiple files.
196
197 The following file types are defined for certmaster:
198
199
200
201 certmaster_etc_rw_t
202
203 - Set files with the certmaster_etc_rw_t type, if you want to treat the
204 files as certmaster etc read/write content.
205
206
207
208 certmaster_exec_t
209
210 - Set files with the certmaster_exec_t type, if you want to transition
211 an executable to the certmaster_t domain.
212
213
214
215 certmaster_initrc_exec_t
216
217 - Set files with the certmaster_initrc_exec_t type, if you want to
218 transition an executable to the certmaster_initrc_t domain.
219
220
221
222 certmaster_var_lib_t
223
224 - Set files with the certmaster_var_lib_t type, if you want to store
225 the certmaster files under the /var/lib directory.
226
227
228
229 certmaster_var_log_t
230
231 - Set files with the certmaster_var_log_t type, if you want to treat
232 the data as certmaster var log data, usually stored under the /var/log
233 directory.
234
235
236
237 certmaster_var_run_t
238
239 - Set files with the certmaster_var_run_t type, if you want to store
240 the certmaster files under the /run or /var/run directory.
241
242
243
244 Note: File context can be temporarily modified with the chcon command.
245 If you want to permanently change the file context you need to use the
246 semanage fcontext command. This will modify the SELinux labeling data‐
247 base. You will need to use restorecon to apply the labels.
248
249
251 semanage fcontext can also be used to manipulate default file context
252 mappings.
253
254 semanage permissive can also be used to manipulate whether or not a
255 process type is permissive.
256
257 semanage module can also be used to enable/disable/install/remove pol‐
258 icy modules.
259
260 semanage port can also be used to manipulate the port definitions
261
262 semanage boolean can also be used to manipulate the booleans
263
264
265 system-config-selinux is a GUI tool available to customize SELinux pol‐
266 icy settings.
