6 vpnc_selinux - Security Enhanced Linux Policy for the vpnc processes
7
9 Security-Enhanced Linux secures the vpnc processes via flexible manda‐
10 tory access control.
11 The vpnc processes execute with the vpnc_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 vpnc_t
19
23 The vpnc_t SELinux type can be entered via the vpnc_exec_t file type.
24 The default entrypoint paths for the vpnc_t domain are the following:
26 /sbin/vpnc, /usr/sbin/vpnc, /usr/bin/openconnect, /usr/sbin/openconnect
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 vpnc policy is very flexible allowing users to setup their vpnc pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for vpnc:
40 vpnc_t
42 Note: semanage permissive -a vpnc_t can be used to make the process
44 type vpnc_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. vpnc
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run vpnc 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. Enabled 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. Enabled by default.
87 setsebool -P nscd_use_shm 1

93 The SELinux process type vpnc_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux vpnc policy is very flexible allowing users to setup their vpnc
145 processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the vpnc, if you wanted to
150 store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use
152 restorecon to put the labels on disk.
153 semanage fcontext -a -t vpnc_var_run_t '/srv/myvpnc_content(/.*)?'
155 restorecon -R -v /srv/myvpnc_content
156 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159 The following file types are defined for vpnc:
161 vpnc_exec_t
165 - Set files with the vpnc_exec_t type, if you want to transition an
167 executable to the vpnc_t domain.
168 Paths:
171 /sbin/vpnc, /usr/sbin/vpnc, /usr/bin/openconnect, /usr/sbin/open‐
172 connect
173 vpnc_tmp_t
176 - Set files with the vpnc_tmp_t type, if you want to store vpnc tempo‐
178 rary files in the /tmp directories.
179 vpnc_var_run_t
183 - Set files with the vpnc_var_run_t type, if you want to store the vpnc
185 files under the /run or /var/run directory.
186 Note: File context can be temporarily modified with the chcon command.
190 If you want to permanently change the file context you need to use the
191 semanage fcontext command. This will modify the SELinux labeling data‐
192 base. You will need to use restorecon to apply the labels.
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage boolean can also be used to manipulate the booleans
206 system-config-selinux is a GUI tool available to customize SELinux pol‐
209 icy settings.
