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
58 default.
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.

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