NAME

6       ssh_keygen_selinux  - Security Enhanced Linux Policy for the ssh_keygen
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the ssh_keygen processes  via  flexible
11       mandatory access control.
12
13       The  ssh_keygen  processes  execute with the ssh_keygen_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 ssh_keygen_t
20
21
22

ENTRYPOINTS

24       The  ssh_keygen_t SELinux type can be entered via the ssh_keygen_exec_t
25       file type.
26
27       The default entrypoint paths for the ssh_keygen_t domain are  the  fol‐
28       lowing:
29
30       /usr/bin/ssh-keygen
31

PROCESS TYPES

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       ssh_keygen  policy  is  very  flexible  allowing  users  to setup their
40       ssh_keygen processes in as secure a method as possible.
41
42       The following process types are defined for ssh_keygen:
43
44       ssh_keygen_t
45
46       Note: semanage permissive -a ssh_keygen_t  can  be  used  to  make  the
47       process  type  ssh_keygen_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       ssh_keygen policy is extremely flexible and has several  booleans  that
55       allow you to manipulate the policy and run ssh_keygen with the tightest
56       access possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1
71

73

MANAGED FILES

75       The SELinux process type ssh_keygen_t can manage files labeled with the
76       following file types.  The paths listed are the default paths for these
77       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

141       SELinux requires files to have an extended attribute to define the file
142       type.
143
144       You can see the context of a file using the -Z option to ls
145
146       Policy  governs  the  access  confined  processes  have to these files.
147       SELinux ssh_keygen policy is very  flexible  allowing  users  to  setup
148       their ssh_keygen processes in as secure a method as possible.
149
150       STANDARD FILE CONTEXT
151
152       SELinux  defines  the  file  context  types  for the ssh_keygen, if you
153       wanted to store files with these types in a diffent paths, you need  to
154       execute  the  semanage  command to sepecify alternate labeling and then
155       use restorecon to put the labels on disk.
156
157       semanage  fcontext  -a  -t   ssh_keygen_tmp_t   '/srv/myssh_keygen_con‐
158       tent(/.*)?'
159       restorecon -R -v /srv/myssh_keygen_content
160
161       Note:  SELinux  often  uses  regular expressions to specify labels that
162       match multiple files.
163
164       The following file types are defined for ssh_keygen:
165
166
167
168       ssh_keygen_exec_t
169
170       - Set files with the ssh_keygen_exec_t type, if you want to  transition
171       an executable to the ssh_keygen_t domain.
172
173
174
175       ssh_keygen_tmp_t
176
177       -  Set  files  with the ssh_keygen_tmp_t type, if you want to store ssh
178       keygen temporary files in the /tmp directories.
179
180
181
182       Note: File context can be temporarily modified with the chcon  command.
183       If  you want to permanently change the file context you need to use the
184       semanage fcontext command.  This will modify the SELinux labeling data‐
185       base.  You will need to use restorecon to apply the labels.
186
187

COMMANDS

189       semanage  fcontext  can also be used to manipulate default file context
190       mappings.
191
192       semanage permissive can also be used to manipulate  whether  or  not  a
193       process type is permissive.
194
195       semanage  module can also be used to enable/disable/install/remove pol‐
196       icy modules.
197
198       semanage boolean can also be used to manipulate the booleans
199
200
201       system-config-selinux is a GUI tool available to customize SELinux pol‐
202       icy settings.
