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.
59 setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Disabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87 setsebool -P nscd_use_shm 1
89
93 SELinux defines port types to represent TCP and UDP ports.
94 You can see the types associated with a port by using the following
96 command:
97 semanage port -l
99 Policy governs the access confined processes have to these ports.
102 SELinux pptp policy is very flexible allowing users to setup their pptp
103 processes in as secure a method as possible.
104 The following port types are defined for pptp:
106 pptp_port_t
109 Default Defined Ports:
113 tcp 1723
114 udp 1723
115
117 The SELinux process type pptp_t can manage files labeled with the fol‐
118 lowing file types. The paths listed are the default paths for these
119 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167 You can see the context of a file using the -Z option to ls
169 Policy governs the access confined processes have to these files.
171 SELinux pptp policy is very flexible allowing users to setup their pptp
172 processes in as secure a method as possible.
173 STANDARD FILE CONTEXT
175 SELinux defines the file context types for the pptp, if you wanted to
177 store files with these types in a diffent paths, you need to execute
178 the semanage command to sepecify alternate labeling and then use
179 restorecon to put the labels on disk.
180 semanage fcontext -a -t pptp_var_run_t '/srv/mypptp_content(/.*)?'
182 restorecon -R -v /srv/mypptp_content
183 Note: SELinux often uses regular expressions to specify labels that
185 match multiple files.
186 The following file types are defined for pptp:
188 pptp_exec_t
192 - Set files with the pptp_exec_t type, if you want to transition an
194 executable to the pptp_t domain.
195 pptp_log_t
199 - Set files with the pptp_log_t type, if you want to treat the data as
201 pptp log data, usually stored under the /var/log directory.
202 pptp_var_run_t
206 - Set files with the pptp_var_run_t type, if you want to store the pptp
208 files under the /run or /var/run directory.
209 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227 semanage port can also be used to manipulate the port definitions
229 semanage boolean can also be used to manipulate the booleans
231 system-config-selinux is a GUI tool available to customize SELinux pol‐
234 icy settings.
