6 ssh_keygen_selinux - Security Enhanced Linux Policy for the ssh_keygen
7 processes
8
10 Security-Enhanced Linux secures the ssh_keygen processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep ssh_keygen_t
20
24 The ssh_keygen_t SELinux type can be entered via the ssh_keygen_exec_t
25 file type.
26 The default entrypoint paths for the ssh_keygen_t domain are the fol‐
28 lowing:
29 /usr/bin/ssh-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 ssh_keygen policy is very flexible allowing users to setup their
40 ssh_keygen processes in as secure a method as possible.
41 The following process types are defined for ssh_keygen:
43 ssh_keygen_t
45 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.
50
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 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 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.

141 SELinux requires files to have an extended attribute to define the file
142 type.
143 You can see the context of a file using the -Z option to ls
145 Policy governs the access confined processes have to these files.
147 SELinux ssh_keygen policy is very flexible allowing users to setup
148 their ssh_keygen processes in as secure a method as possible.
149 STANDARD FILE CONTEXT
151 SELinux defines the file context types for the ssh_keygen, if you
153 wanted to store files with these types in a diffent paths, you need to
154 execute the semanage command to sepecify alternate labeling and then
155 use restorecon to put the labels on disk.
156 semanage fcontext -a -t ssh_keygen_tmp_t '/srv/myssh_keygen_con‐
158 tent(/.*)?'
159 restorecon -R -v /srv/myssh_keygen_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for ssh_keygen:
165 ssh_keygen_exec_t
169 - Set files with the ssh_keygen_exec_t type, if you want to transition
171 an executable to the ssh_keygen_t domain.
172 ssh_keygen_tmp_t
176 - Set files with the ssh_keygen_tmp_t type, if you want to store ssh
178 keygen temporary files in the /tmp directories.
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.
