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.

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

124       SELinux requires files to have an extended attribute to define the file
125       type.
126
127       You can see the context of a file using the -Z option to ls
128
129       Policy  governs  the  access  confined  processes  have to these files.
130       SELinux ssh_keygen policy is very  flexible  allowing  users  to  setup
131       their ssh_keygen processes in as secure a method as possible.
132
133       STANDARD FILE CONTEXT
134
135       SELinux  defines  the  file  context  types  for the ssh_keygen, if you
136       wanted to store files with these types in a diffent paths, you need  to
137       execute  the  semanage  command to sepecify alternate labeling and then
138       use restorecon to put the labels on disk.
139
140       semanage  fcontext  -a  -t   ssh_keygen_tmp_t   '/srv/myssh_keygen_con‐
141       tent(/.*)?'
142       restorecon -R -v /srv/myssh_keygen_content
143
144       Note:  SELinux  often  uses  regular expressions to specify labels that
145       match multiple files.
146
147       The following file types are defined for ssh_keygen:
148
149
150
151       ssh_keygen_exec_t
152
153       - Set files with the ssh_keygen_exec_t type, if you want to  transition
154       an executable to the ssh_keygen_t domain.
155
156
157
158       ssh_keygen_tmp_t
159
160       -  Set  files  with the ssh_keygen_tmp_t type, if you want to store ssh
161       keygen temporary files in the /tmp directories.
162
163
164
165       Note: File context can be temporarily modified with the chcon  command.
166       If  you want to permanently change the file context you need to use the
167       semanage fcontext command.  This will modify the SELinux labeling data‐
168       base.  You will need to use restorecon to apply the labels.

COMMANDS

172       semanage  fcontext  can also be used to manipulate default file context
173       mappings.
174
175       semanage permissive can also be used to manipulate  whether  or  not  a
176       process type is permissive.
177
178       semanage  module can also be used to enable/disable/install/remove pol‐
179       icy modules.
180
181       semanage boolean can also be used to manipulate the booleans
182
183
184       system-config-selinux is a GUI tool available to customize SELinux pol‐
185       icy settings.
