6 gssproxy_selinux - Security Enhanced Linux Policy for the gssproxy pro‐
7 cesses
8
10 Security-Enhanced Linux secures the gssproxy processes via flexible
11 mandatory access control.
12 The gssproxy processes execute with the gssproxy_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep gssproxy_t
20
24 The gssproxy_t SELinux type can be entered via the gssproxy_exec_t file
25 type.
26 The default entrypoint paths for the gssproxy_t domain are the follow‐
28 ing:
29 /usr/sbin/gssproxy
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 gssproxy policy is very flexible allowing users to setup their gssproxy
40 processes in as secure a method as possible.
41 The following process types are defined for gssproxy:
43 gssproxy_t
45 Note: semanage permissive -a gssproxy_t can be used to make the process
47 type gssproxy_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required.
54 gssproxy policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run gssproxy with the tightest
56 access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1

97 The SELinux process type gssproxy_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

190 SELinux requires files to have an extended attribute to define the file
191 type.
192 You can see the context of a file using the -Z option to ls
194 Policy governs the access confined processes have to these files.
196 SELinux gssproxy policy is very flexible allowing users to setup their
197 gssproxy processes in as secure a method as possible.
198 STANDARD FILE CONTEXT
200 SELinux defines the file context types for the gssproxy, if you wanted
202 to store files with these types in a diffent paths, you need to execute
203 the semanage command to sepecify alternate labeling and then use
204 restorecon to put the labels on disk.
205 semanage fcontext -a -t gssproxy_unit_file_t '/srv/mygssproxy_con‐
207 tent(/.*)?'
208 restorecon -R -v /srv/mygssproxy_content
209 Note: SELinux often uses regular expressions to specify labels that
211 match multiple files.
212 The following file types are defined for gssproxy:
214 gssproxy_exec_t
218 - Set files with the gssproxy_exec_t type, if you want to transition an
220 executable to the gssproxy_t domain.
221 gssproxy_unit_file_t
225 - Set files with the gssproxy_unit_file_t type, if you want to treat
227 the files as gssproxy unit content.
228 gssproxy_var_lib_t
232 - Set files with the gssproxy_var_lib_t type, if you want to store the
234 gssproxy files under the /var/lib directory.
235 gssproxy_var_run_t
239 - Set files with the gssproxy_var_run_t type, if you want to store the
241 gssproxy files under the /run or /var/run directory.
242 Paths:
245 /var/run/gssproxy.pid, /var/run/gssproxy.sock
246 Note: File context can be temporarily modified with the chcon command.
249 If you want to permanently change the file context you need to use the
250 semanage fcontext command. This will modify the SELinux labeling data‐
251 base. You will need to use restorecon to apply the labels.
252
255 semanage fcontext can also be used to manipulate default file context
256 mappings.
257 semanage permissive can also be used to manipulate whether or not a
259 process type is permissive.
260 semanage module can also be used to enable/disable/install/remove pol‐
262 icy modules.
263 semanage boolean can also be used to manipulate the booleans
265 system-config-selinux is a GUI tool available to customize SELinux pol‐
268 icy settings.
