6 sshd_keygen_selinux - Security Enhanced Linux Policy for the sshd_key‐
7 gen processes
8
10 Security-Enhanced Linux secures the sshd_keygen processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep sshd_keygen_t
20
24 The sshd_keygen_t SELinux type can be entered via the sshd_key‐
25 gen_exec_t file type.
26 The default entrypoint paths for the sshd_keygen_t domain are the fol‐
28 lowing:
29 /usr/sbin/sshd-keygen, /usr/libexec/openssh/sshd-keygen
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for sshd_keygen:
43 sshd_keygen_t
45 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.
50
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 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 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type sshd_keygen_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux sshd_keygen policy is very flexible allowing users to setup
145 their sshd_keygen processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the sshd_keygen, if you
150 wanted to store files with these types in a diffent paths, you need to
151 execute the semanage command to specify alternate labeling and then use
152 restorecon to put the labels on disk.
153 semanage fcontext -a -t sshd_keygen_unit_file_t '/srv/mysshd_key‐
155 gen_content(/.*)?'
156 restorecon -R -v /srv/mysshd_keygen_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for sshd_keygen:
162 sshd_keygen_exec_t
166 - Set files with the sshd_keygen_exec_t type, if you want to transition
168 an executable to the sshd_keygen_t domain.
169 Paths:
172 /usr/sbin/sshd-keygen, /usr/libexec/openssh/sshd-keygen
173 sshd_keygen_unit_file_t
176 - Set files with the sshd_keygen_unit_file_t type, if you want to treat
178 the files as sshd keygen unit content.
179 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
189 semanage fcontext can also be used to manipulate default file context
190 mappings.
191 semanage permissive can also be used to manipulate whether or not a
193 process type is permissive.
194 semanage module can also be used to enable/disable/install/remove pol‐
196 icy modules.
197 semanage boolean can also be used to manipulate the booleans
199 system-config-selinux is a GUI tool available to customize SELinux pol‐
202 icy settings.
