6 numad_selinux - Security Enhanced Linux Policy for the numad processes
7
9 Security-Enhanced Linux secures the numad processes via flexible manda‐
10 tory access control.
11
12 The numad processes execute with the numad_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 numad_t
19
20
21
23 The numad_t SELinux type can be entered via the numad_exec_t file type.
24
25 The default entrypoint paths for the numad_t domain are the following:
26
27 /usr/bin/numad
28
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 numad policy is very flexible allowing users to setup their numad pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for numad:
40
41 numad_t
42
43 Note: semanage permissive -a numad_t can be used to make the process
44 type numad_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
50 SELinux policy is customizable based on least access required. numad
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run numad with the tightest access possible.
53
54
55
56 If you want to deny any process from ptracing or debugging any other
57 processes, you must turn on the deny_ptrace boolean. Enabled by de‐
58 fault.
59
60 setsebool -P deny_ptrace 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
72 The SELinux process type numad_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

130 SELinux requires files to have an extended attribute to define the file
131 type.
132
133 You can see the context of a file using the -Z option to ls
134
135 Policy governs the access confined processes have to these files.
136 SELinux numad policy is very flexible allowing users to setup their nu‐
137 mad processes in as secure a method as possible.
138
139 STANDARD FILE CONTEXT
140
141 SELinux defines the file context types for the numad, if you wanted to
142 store files with these types in a diffent paths, you need to execute
143 the semanage command to specify alternate labeling and then use re‐
144 storecon to put the labels on disk.
145
146 semanage fcontext -a -t numad_var_run_t '/srv/mynumad_content(/.*)?'
147 restorecon -R -v /srv/mynumad_content
148
149 Note: SELinux often uses regular expressions to specify labels that
150 match multiple files.
151
152 The following file types are defined for numad:
153
154
155
156 numad_exec_t
157
158 - Set files with the numad_exec_t type, if you want to transition an
159 executable to the numad_t domain.
160
161
162
163 numad_unit_file_t
164
165 - Set files with the numad_unit_file_t type, if you want to treat the
166 files as numad unit content.
167
168
169
170 numad_var_log_t
171
172 - Set files with the numad_var_log_t type, if you want to treat the
173 data as numad var log data, usually stored under the /var/log direc‐
174 tory.
175
176
177
178 numad_var_run_t
179
180 - Set files with the numad_var_run_t type, if you want to store the nu‐
181 mad files under the /run or /var/run directory.
182
183
184
185 Note: File context can be temporarily modified with the chcon command.
186 If you want to permanently change the file context you need to use the
187 semanage fcontext command. This will modify the SELinux labeling data‐
188 base. You will need to use restorecon to apply the labels.
189
190
192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194
195 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197
198 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200
201 semanage boolean can also be used to manipulate the booleans
202
203
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
