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
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 all domains to use other domains file descriptors,
57 you must turn on the allow_domain_fd_use boolean. Enabled by default.
58 setsebool -P allow_domain_fd_use 1
60 If you want to allow confined applications to run with kerberos, you
64 must turn on the allow_kerberos boolean. Enabled by default.
65 setsebool -P allow_kerberos 1
67 If you want to allow sysadm to debug or ptrace all processes, you must
71 turn on the allow_ptrace boolean. Disabled by default.
72 setsebool -P allow_ptrace 1
74 If you want to allow system to run with NIS, you must turn on the
78 allow_ypbind boolean. Disabled by default.
79 setsebool -P allow_ypbind 1
81 If you want to allow all domains to have the kernel load modules, you
85 must turn on the domain_kernel_load_modules boolean. Disabled by
86 default.
87 setsebool -P domain_kernel_load_modules 1
89 If you want to allow all domains to execute in fips_mode, you must turn
93 on the fips_mode boolean. Enabled by default.
94 setsebool -P fips_mode 1
96 If you want to enable reading of urandom for all domains, you must turn
100 on the global_ssp boolean. Disabled by default.
101 setsebool -P global_ssp 1
103 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Enabled by default.
108 setsebool -P nscd_use_shm 1
110
114 The SELinux process type vpnc_t can manage files labeled with the fol‐
115 lowing file types. The paths listed are the default paths for these
116 file types. Note the processes UID still need to have DAC permissions.

167 SELinux requires files to have an extended attribute to define the file
168 type.
169 You can see the context of a file using the -Z option to ls
171 Policy governs the access confined processes have to these files.
173 SELinux vpnc policy is very flexible allowing users to setup their vpnc
174 processes in as secure a method as possible.
175 STANDARD FILE CONTEXT
177 SELinux defines the file context types for the vpnc, if you wanted to
179 store files with these types in a diffent paths, you need to execute
180 the semanage command to sepecify alternate labeling and then use
181 restorecon to put the labels on disk.
182 semanage fcontext -a -t vpnc_var_run_t '/srv/myvpnc_content(/.*)?'
184 restorecon -R -v /srv/myvpnc_content
185 Note: SELinux often uses regular expressions to specify labels that
187 match multiple files.
188 The following file types are defined for vpnc:
190 vpnc_exec_t
194 - Set files with the vpnc_exec_t type, if you want to transition an
196 executable to the vpnc_t domain.
197 Paths:
200 /sbin/vpnc, /usr/sbin/vpnc, /usr/bin/openconnect
201 vpnc_tmp_t
204 - Set files with the vpnc_tmp_t type, if you want to store vpnc tempo‐
206 rary files in the /tmp directories.
207 vpnc_var_run_t
211 - Set files with the vpnc_var_run_t type, if you want to store the vpnc
213 files under the /run or /var/run directory.
214 Note: File context can be temporarily modified with the chcon command.
218 If you want to permanently change the file context you need to use the
219 semanage fcontext command. This will modify the SELinux labeling data‐
220 base. You will need to use restorecon to apply the labels.
221
224 semanage fcontext can also be used to manipulate default file context
225 mappings.
226 semanage permissive can also be used to manipulate whether or not a
228 process type is permissive.
229 semanage module can also be used to enable/disable/install/remove pol‐
231 icy modules.
232 semanage boolean can also be used to manipulate the booleans
234 system-config-selinux is a GUI tool available to customize SELinux pol‐
237 icy settings.
