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 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. Disabled 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 sshd_keygen_t can manage  files  labeled  with
98       the  following  file types.  The paths listed are the default paths for
99       these file types.  Note the processes UID still need to have  DAC  per‐
100       missions.

104            /etc/cluster(/.*)?

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  sshd_keygen  policy  is  very flexible allowing users to setup
152       their sshd_keygen processes in as secure a method as possible.
153
154       STANDARD FILE CONTEXT
155
156       SELinux defines the file context types  for  the  sshd_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  sshd_keygen_unit_file_t  '/srv/mysshd_key‐
162       gen_content(/.*)?'
163       restorecon -R -v /srv/mysshd_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 sshd_keygen:
169
170
171
172       sshd_keygen_exec_t
173
174       - Set files with the sshd_keygen_exec_t type, if you want to transition
175       an executable to the sshd_keygen_t domain.
176
177
178       Paths:
179            /usr/sbin/sshd-keygen, /usr/libexec/openssh/sshd-keygen
180
181
182       sshd_keygen_unit_file_t
183
184       - Set files with the sshd_keygen_unit_file_t type, if you want to treat
185       the files as sshd keygen unit content.
186
187
188
189       Note:  File context can be temporarily modified with the chcon command.
190       If you want to permanently change the file context you need to use  the
191       semanage fcontext command.  This will modify the SELinux labeling data‐
192       base.  You will need to use restorecon to apply the labels.
193
194

COMMANDS

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