6 sslh_selinux - Security Enhanced Linux Policy for the sslh processes
7
9 Security-Enhanced Linux secures the sslh processes via flexible manda‐
10 tory access control.
11 The sslh processes execute with the sslh_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep sslh_t
19
23 The sslh_t SELinux type can be entered via the sslh_exec_t file type.
24 The default entrypoint paths for the sslh_t domain are the following:
26 /usr/sbin/sslh, /usr/sbin/sslh-select
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 sslh policy is very flexible allowing users to setup their sslh pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for sslh:
40 sslh_t
42 Note: semanage permissive -a sslh_t can be used to make the process
44 type sslh_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. sslh
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run sslh with the tightest access possible.
53 If you want to determine whether sslh can listen on any tcp port or if
57 it is restricted to the standard http, you must turn on the
58 sslh_can_bind_any_port boolean. Disabled by default.
59 setsebool -P sslh_can_bind_any_port 1
61 If you want to determine whether sslh can connect to any tcp port or if
65 it is restricted to the standard http, openvpn and jabber ports, you
66 must turn on the sslh_can_connect_any_port boolean. Disabled by de‐
67 fault.
68 setsebool -P sslh_can_connect_any_port 1
70 If you want to allow all domains to execute in fips_mode, you must turn
74 on the fips_mode boolean. Enabled by default.
75 setsebool -P fips_mode 1
77 If you want to allow confined applications to use nscd shared memory,
81 you must turn on the nscd_use_shm boolean. Enabled by default.
82 setsebool -P nscd_use_shm 1
84
88 The SELinux process type sslh_t can manage files labeled with the fol‐
89 lowing file types. The paths listed are the default paths for these
90 file types. Note the processes UID still need to have DAC permissions.

134 SELinux requires files to have an extended attribute to define the file
135 type.
136 You can see the context of a file using the -Z option to ls
138 Policy governs the access confined processes have to these files.
140 SELinux sslh policy is very flexible allowing users to setup their sslh
141 processes in as secure a method as possible.
142 STANDARD FILE CONTEXT
144 SELinux defines the file context types for the sslh, if you wanted to
146 store files with these types in a diffent paths, you need to execute
147 the semanage command to sepecify alternate labeling and then use re‐
148 storecon to put the labels on disk.
149 semanage fcontext -a -t sslh_unit_file_t '/srv/mysslh_content(/.*)?'
151 restorecon -R -v /srv/mysslh_content
152 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155 The following file types are defined for sslh:
157 sslh_config_t
161 - Set files with the sslh_config_t type, if you want to treat the files
163 as sslh configuration data, usually stored under the /etc directory.
164 Paths:
167 /etc/sslh(/.*)?, /etc/sslh.cfg, /etc/sysconfig/sslh
168 sslh_exec_t
171 - Set files with the sslh_exec_t type, if you want to transition an ex‐
173 ecutable to the sslh_t domain.
174 Paths:
177 /usr/sbin/sslh, /usr/sbin/sslh-select
178 sslh_initrc_exec_t
181 - Set files with the sslh_initrc_exec_t type, if you want to transition
183 an executable to the sslh_initrc_t domain.
184 sslh_unit_file_t
188 - Set files with the sslh_unit_file_t type, if you want to treat the
190 files as sslh unit content.
191 sslh_var_run_t
195 - Set files with the sslh_var_run_t type, if you want to store the sslh
197 files under the /run or /var/run directory.
198 Note: File context can be temporarily modified with the chcon command.
202 If you want to permanently change the file context you need to use the
203 semanage fcontext command. This will modify the SELinux labeling data‐
204 base. You will need to use restorecon to apply the labels.
205
208 semanage fcontext can also be used to manipulate default file context
209 mappings.
210 semanage permissive can also be used to manipulate whether or not a
212 process type is permissive.
213 semanage module can also be used to enable/disable/install/remove pol‐
215 icy modules.
216 semanage boolean can also be used to manipulate the booleans
218 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
