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.

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 users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Disabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

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

FILE CONTEXTS

145       SELinux requires files to have an extended attribute to define the file
146       type.
147
148       You can see the context of a file using the -Z option to ls
149
150       Policy  governs  the  access  confined  processes  have to these files.
151       SELinux ssh_keygen policy is very  flexible  allowing  users  to  setup
152       their ssh_keygen processes in as secure a method as possible.
153
154       STANDARD FILE CONTEXT
155
156       SELinux  defines  the  file  context  types  for the ssh_keygen, if you
157       wanted to store files with these types in a diffent paths, you need  to
158       execute  the  semanage  command to sepecify alternate labeling and then
159       use restorecon to put the labels on disk.
160
161       semanage  fcontext  -a  -t   ssh_keygen_tmp_t   '/srv/myssh_keygen_con‐
162       tent(/.*)?'
163       restorecon -R -v /srv/myssh_keygen_content
164
165       Note:  SELinux  often  uses  regular expressions to specify labels that
166       match multiple files.
167
168       The following file types are defined for ssh_keygen:
169
170
171
172       ssh_keygen_exec_t
173
174       - Set files with the ssh_keygen_exec_t type, if you want to  transition
175       an executable to the ssh_keygen_t domain.
176
177
178
179       ssh_keygen_tmp_t
180
181       -  Set  files  with the ssh_keygen_tmp_t type, if you want to store ssh
182       keygen temporary files in the /tmp directories.
183
184
185
186       Note: File context can be temporarily modified with the chcon  command.
187       If  you want to permanently change the file context you need to use the
188       semanage fcontext command.  This will modify the SELinux labeling data‐
189       base.  You will need to use restorecon to apply the labels.
190
191

COMMANDS

193       semanage  fcontext  can also be used to manipulate default file context
194       mappings.
195
196       semanage permissive can also be used to manipulate  whether  or  not  a
197       process type is permissive.
198
199       semanage  module can also be used to enable/disable/install/remove pol‐
200       icy modules.
201
202       semanage boolean can also be used to manipulate the booleans
203
204
205       system-config-selinux is a GUI tool available to customize SELinux pol‐
206       icy settings.
