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 dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 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 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

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.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 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 STANDARD FILE CONTEXT
156 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 semanage fcontext -a -t sshd_keygen_exec_t '/srv/sshd_keygen/con‐
163 tent(/.*)?'
164 restorecon -R -v /srv/mysshd_keygen_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for sshd_keygen:
170 sshd_keygen_exec_t
174 - Set files with the sshd_keygen_exec_t type, if you want to transition
176 an executable to the sshd_keygen_t domain.
177 Paths:
180 /usr/sbin/sshd-keygen, /usr/libexec/openssh/sshd-keygen
181 sshd_keygen_unit_file_t
184 - Set files with the sshd_keygen_unit_file_t type, if you want to treat
186 the files as sshd keygen unit content.
187 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
197 semanage fcontext can also be used to manipulate default file context
198 mappings.
199 semanage permissive can also be used to manipulate whether or not a
201 process type is permissive.
202 semanage module can also be used to enable/disable/install/remove pol‐
204 icy modules.
205 semanage boolean can also be used to manipulate the booleans
207 system-config-selinux is a GUI tool available to customize SELinux pol‐
210 icy settings.
