6 ejabberd_selinux - Security Enhanced Linux Policy for the ejabberd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ejabberd processes via flexible
11 mandatory access control.
12 The ejabberd processes execute with the ejabberd_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 ejabberd_t
20
24 The ejabberd_t SELinux type can be entered via the ejabberd_exec_t file
25 type.
26 The default entrypoint paths for the ejabberd_t domain are the follow‐
28 ing:
29 /usr/bin/ejabberdctl
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 ejabberd policy is very flexible allowing users to setup their ejabberd
40 processes in as secure a method as possible.
41 The following process types are defined for ejabberd:
43 ejabberd_t
45 Note: semanage permissive -a ejabberd_t can be used to make the process
47 type ejabberd_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. ejab‐
54 berd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run ejabberd with the tightest access
56 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. Enabled 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. Enabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type ejabberd_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.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 Policy governs the access confined processes have to these files.
152 SELinux ejabberd policy is very flexible allowing users to setup their
153 ejabberd processes in as secure a method as possible.
154 STANDARD FILE CONTEXT
156 SELinux defines the file context types for the ejabberd, if you wanted
158 to store files with these types in a diffent paths, you need to execute
159 the semanage command to sepecify alternate labeling and then use
160 restorecon to put the labels on disk.
161 semanage fcontext -a -t ejabberd_var_log_t '/srv/myejabberd_con‐
163 tent(/.*)?'
164 restorecon -R -v /srv/myejabberd_content
165 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168 The following file types are defined for ejabberd:
170 ejabberd_exec_t
174 - Set files with the ejabberd_exec_t type, if you want to transition an
176 executable to the ejabberd_t domain.
177 ejabberd_unit_t
181 - Set files with the ejabberd_unit_t type, if you want to treat the
183 files as ejabberd unit data.
184 ejabberd_var_lib_t
188 - Set files with the ejabberd_var_lib_t type, if you want to store the
190 ejabberd files under the /var/lib directory.
191 ejabberd_var_log_t
195 - Set files with the ejabberd_var_log_t type, if you want to treat the
197 data as ejabberd var log data, usually stored under the /var/log direc‐
198 tory.
199 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217 semanage boolean can also be used to manipulate the booleans
219 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
