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 dontaudit all daemons scheduling requests (setsched,
74 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
75 Enabled by default.
76 setsebool -P daemons_dontaudit_scheduling 1
78 If you want to allow all domains to execute in fips_mode, you must turn
82 on the fips_mode boolean. Enabled by default.
83 setsebool -P fips_mode 1
85 If you want to allow confined applications to use nscd shared memory,
89 you must turn on the nscd_use_shm boolean. Enabled by default.
90 setsebool -P nscd_use_shm 1

96 The SELinux process type sslh_t can manage files labeled with the fol‐
97 lowing file types. The paths listed are the default paths for these
98 file types. Note the processes UID still need to have DAC permissions.

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux sslh policy is very flexible allowing users to setup their sslh
149 processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the sslh, if you wanted to
154 store files with these types in a different paths, you need to execute
155 the semanage command to specify alternate labeling and then use re‐
156 storecon to put the labels on disk.
157 semanage fcontext -a -t sslh_exec_t '/srv/sslh/content(/.*)?'
159 restorecon -R -v /srv/mysslh_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for sslh:
165 sslh_config_t
169 - Set files with the sslh_config_t type, if you want to treat the files
171 as sslh configuration data, usually stored under the /etc directory.
172 Paths:
175 /etc/sslh(/.*)?, /etc/sslh.cfg, /etc/sysconfig/sslh
176 sslh_exec_t
179 - Set files with the sslh_exec_t type, if you want to transition an ex‐
181 ecutable to the sslh_t domain.
182 Paths:
185 /usr/sbin/sslh, /usr/sbin/sslh-select
186 sslh_initrc_exec_t
189 - Set files with the sslh_initrc_exec_t type, if you want to transition
191 an executable to the sslh_initrc_t domain.
192 sslh_unit_file_t
196 - Set files with the sslh_unit_file_t type, if you want to treat the
198 files as sslh unit content.
199 sslh_var_run_t
203 - Set files with the sslh_var_run_t type, if you want to store the sslh
205 files under the /run or /var/run directory.
206 Note: File context can be temporarily modified with the chcon command.
210 If you want to permanently change the file context you need to use the
211 semanage fcontext command. This will modify the SELinux labeling data‐
212 base. You will need to use restorecon to apply the labels.
213
216 semanage fcontext can also be used to manipulate default file context
217 mappings.
218 semanage permissive can also be used to manipulate whether or not a
220 process type is permissive.
221 semanage module can also be used to enable/disable/install/remove pol‐
223 icy modules.
224 semanage boolean can also be used to manipulate the booleans
226 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
