NAME

6       sshd_keygen_selinux  - Security Enhanced Linux Policy for the sshd_key‐
7       gen processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sshd_keygen processes via  flexible
11       mandatory access control.
12
13       The  sshd_keygen processes execute with the sshd_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 sshd_keygen_t
20

22

ENTRYPOINTS

24       The  sshd_keygen_t  SELinux  type  can  be  entered  via  the sshd_key‐
25       gen_exec_t file type.
26
27       The default entrypoint paths for the sshd_keygen_t domain are the  fol‐
28       lowing:
29
30       /usr/sbin/sshd-keygen, /usr/libexec/openssh/sshd-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       sshd_keygen  policy  is  very  flexible  allowing  users to setup their
40       sshd_keygen processes in as secure a method as possible.
41
42       The following process types are defined for sshd_keygen:
43
44       sshd_keygen_t
45
46       Note: semanage permissive -a sshd_keygen_t can  be  used  to  make  the
47       process  type sshd_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       sshd_keygen policy is extremely flexible and has several booleans  that
55       allow  you to manipulate the policy and run sshd_keygen with the tight‐
56       est access possible.
57
58
59
60       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
61       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
62       Enabled by default.
63
64       setsebool -P daemons_dontaudit_scheduling 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  system  to run with NIS, you must turn on the
76       nis_enabled boolean. Disabled by default.
77
78       setsebool -P nis_enabled 1

MANAGED FILES

83       The SELinux process type sshd_keygen_t can manage  files  labeled  with
84       the  following  file types.  The paths listed are the default paths for
85       these file types.  Note the processes UID still need to have  DAC  per‐
86       missions.

FILE CONTEXTS

146       SELinux requires files to have an extended attribute to define the file
147       type.
148
149       You can see the context of a file using the -Z option to ls
150
151       Policy governs the access  confined  processes  have  to  these  files.
152       SELinux  sshd_keygen  policy  is  very flexible allowing users to setup
153       their sshd_keygen processes in as secure a method as possible.
154
155       STANDARD FILE CONTEXT
156
157       SELinux defines the file context types  for  the  sshd_keygen,  if  you
158       wanted  to  store files with these types in a different paths, you need
159       to execute the semanage command to specify alternate labeling and  then
160       use restorecon to put the labels on disk.
161
162       semanage   fcontext  -a  -t  sshd_keygen_exec_t  '/srv/sshd_keygen/con‐
163       tent(/.*)?'
164       restorecon -R -v /srv/mysshd_keygen_content
165
166       Note: SELinux often uses regular expressions  to  specify  labels  that
167       match multiple files.
168
169       The following file types are defined for sshd_keygen:
170
171
172
173       sshd_keygen_exec_t
174
175       - Set files with the sshd_keygen_exec_t type, if you want to transition
176       an executable to the sshd_keygen_t domain.
177
178
179       Paths:
180            /usr/sbin/sshd-keygen, /usr/libexec/openssh/sshd-keygen
181
182
183       sshd_keygen_unit_file_t
184
185       - Set files with the sshd_keygen_unit_file_t type, if you want to treat
186       the files as sshd keygen unit content.
187
188
189
190       Note:  File context can be temporarily modified with the chcon command.
191       If you want to permanently change the file context you need to use  the
192       semanage fcontext command.  This will modify the SELinux labeling data‐
193       base.  You will need to use restorecon to apply the labels.
194
195

COMMANDS

197       semanage fcontext can also be used to manipulate default  file  context
198       mappings.
199
200       semanage  permissive  can  also  be used to manipulate whether or not a
201       process type is permissive.
202
203       semanage module can also be used to enable/disable/install/remove  pol‐
204       icy modules.
205
206       semanage boolean can also be used to manipulate the booleans
207
208
209       system-config-selinux is a GUI tool available to customize SELinux pol‐
210       icy settings.
