6 pptp_selinux - Security Enhanced Linux Policy for the pptp processes
7
9 Security-Enhanced Linux secures the pptp processes via flexible manda‐
10 tory access control.
11 The pptp processes execute with the pptp_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 pptp_t
19
23 The pptp_t SELinux type can be entered via the pptp_exec_t file type.
24 The default entrypoint paths for the pptp_t domain are the following:
26 /usr/sbin/pptp
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 pptp policy is very flexible allowing users to setup their pptp pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for pptp:
40 pptp_t
42 Note: semanage permissive -a pptp_t can be used to make the process
44 type pptp_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. pptp
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run pptp with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.

139 on the global_ssp boolean. Disabled by default.
140 setsebool -P global_ssp 1
142 If you want to allow confined applications to run with kerberos, you
146 must turn on the kerberos_enabled boolean. Enabled by default.
147 setsebool -P kerberos_enabled 1
149 If you want to allow system to run with NIS, you must turn on the
153 nis_enabled boolean. Disabled by default.
154 setsebool -P nis_enabled 1
156 If you want to allow confined applications to use nscd shared memory,
160 you must turn on the nscd_use_shm boolean. Disabled by default.
161 setsebool -P nscd_use_shm 1

167 SELinux defines port types to represent TCP and UDP ports.
168 You can see the types associated with a port by using the following
170 command:
171 semanage port -l
173 Policy governs the access confined processes have to these ports.
176 SELinux pptp policy is very flexible allowing users to setup their pptp
177 processes in as secure a method as possible.
178 The following port types are defined for pptp:
180 pptp_port_t
183 Default Defined Ports:
187 tcp 1723
188 udp 1723
189
191 The SELinux process type pptp_t can manage files labeled with the fol‐
192 lowing file types. The paths listed are the default paths for these
193 file types. Note the processes UID still need to have DAC permissions.

239 SELinux requires files to have an extended attribute to define the file
240 type.
241 You can see the context of a file using the -Z option to ls
243 Policy governs the access confined processes have to these files.
245 SELinux pptp policy is very flexible allowing users to setup their pptp
246 processes in as secure a method as possible.
247 STANDARD FILE CONTEXT
249 SELinux defines the file context types for the pptp, if you wanted to
251 store files with these types in a diffent paths, you need to execute
252 the semanage command to sepecify alternate labeling and then use
253 restorecon to put the labels on disk.
254 semanage fcontext -a -t pptp_var_run_t '/srv/mypptp_content(/.*)?'
256 restorecon -R -v /srv/mypptp_content
257 Note: SELinux often uses regular expressions to specify labels that
259 match multiple files.
260 The following file types are defined for pptp:
262 pptp_exec_t
266 - Set files with the pptp_exec_t type, if you want to transition an
268 executable to the pptp_t domain.
269 pptp_log_t
273 - Set files with the pptp_log_t type, if you want to treat the data as
275 pptp log data, usually stored under the /var/log directory.
276 pptp_var_run_t
280 - Set files with the pptp_var_run_t type, if you want to store the pptp
282 files under the /run or /var/run directory.
283 Note: File context can be temporarily modified with the chcon command.
287 If you want to permanently change the file context you need to use the
288 semanage fcontext command. This will modify the SELinux labeling data‐
289 base. You will need to use restorecon to apply the labels.
290
293 semanage fcontext can also be used to manipulate default file context
294 mappings.
295 semanage permissive can also be used to manipulate whether or not a
297 process type is permissive.
298 semanage module can also be used to enable/disable/install/remove pol‐
300 icy modules.
301 semanage port can also be used to manipulate the port definitions
303 semanage boolean can also be used to manipulate the booleans
305 system-config-selinux is a GUI tool available to customize SELinux pol‐
308 icy settings.
