NAME

6       numad_selinux - Security Enhanced Linux Policy for the numad processes
7

DESCRIPTION

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

21

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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

MANAGED FILES

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.

FILE CONTEXTS

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 sepecify 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

COMMANDS

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.
