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 dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59 setsebool -P daemons_dontaudit_scheduling 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow system to run with NIS, you must turn on the
72 nis_enabled boolean. Disabled by default.
73 setsebool -P nis_enabled 1
75
79 SELinux defines port types to represent TCP and UDP ports.
80 You can see the types associated with a port by using the following
82 command:
83 semanage port -l
85 Policy governs the access confined processes have to these ports.
88 SELinux pptp policy is very flexible allowing users to setup their pptp
89 processes in as secure a method as possible.
90 The following port types are defined for pptp:
92 pptp_port_t
95 Default Defined Ports:
99 tcp 1723
100 udp 1723
101
103 The SELinux process type pptp_t can manage files labeled with the fol‐
104 lowing file types. The paths listed are the default paths for these
105 file types. Note the processes UID still need to have DAC permissions.

166 SELinux requires files to have an extended attribute to define the file
167 type.
168 You can see the context of a file using the -Z option to ls
170 Policy governs the access confined processes have to these files.
172 SELinux pptp policy is very flexible allowing users to setup their pptp
173 processes in as secure a method as possible.
174 STANDARD FILE CONTEXT
176 SELinux defines the file context types for the pptp, if you wanted to
178 store files with these types in a different paths, you need to execute
179 the semanage command to specify alternate labeling and then use re‐
180 storecon to put the labels on disk.
181 semanage fcontext -a -t pptp_exec_t '/srv/pptp/content(/.*)?'
183 restorecon -R -v /srv/mypptp_content
184 Note: SELinux often uses regular expressions to specify labels that
186 match multiple files.
187 The following file types are defined for pptp:
189 pptp_exec_t
193 - Set files with the pptp_exec_t type, if you want to transition an ex‐
195 ecutable to the pptp_t domain.
196 pptp_log_t
200 - Set files with the pptp_log_t type, if you want to treat the data as
202 pptp log data, usually stored under the /var/log directory.
203 pptp_var_run_t
207 - Set files with the pptp_var_run_t type, if you want to store the pptp
209 files under the /run or /var/run directory.
210 Note: File context can be temporarily modified with the chcon command.
214 If you want to permanently change the file context you need to use the
215 semanage fcontext command. This will modify the SELinux labeling data‐
216 base. You will need to use restorecon to apply the labels.
217
220 semanage fcontext can also be used to manipulate default file context
221 mappings.
222 semanage permissive can also be used to manipulate whether or not a
224 process type is permissive.
225 semanage module can also be used to enable/disable/install/remove pol‐
227 icy modules.
228 semanage port can also be used to manipulate the port definitions
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
