6 memcached_selinux - Security Enhanced Linux Policy for the memcached
7 processes
8
10 Security-Enhanced Linux secures the memcached processes via flexible
11 mandatory access control.
12 The memcached processes execute with the memcached_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 memcached_t
20
24 The memcached_t SELinux type can be entered via the memcached_exec_t
25 file type.
26 The default entrypoint paths for the memcached_t domain are the follow‐
28 ing:
29 /usr/bin/memcached
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 memcached policy is very flexible allowing users to setup their mem‐
40 cached processes in as secure a method as possible.
41 The following process types are defined for memcached:
43 memcached_t
45 Note: semanage permissive -a memcached_t can be used to make the
47 process type memcached_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. mem‐
54 cached policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run memcached with the tightest access
56 possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 SELinux defines port types to represent TCP and UDP ports.
69 You can see the types associated with a port by using the following
71 command:
72 semanage port -l
74 Policy governs the access confined processes have to these ports.
77 SELinux memcached policy is very flexible allowing users to setup their
78 memcached processes in as secure a method as possible.
79 The following port types are defined for memcached:
81 memcache_port_t
84 Default Defined Ports:
88 tcp 11211
89 udp 11211
90
92 The SELinux process type memcached_t can manage files labeled with the
93 following file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.

153 SELinux requires files to have an extended attribute to define the file
154 type.
155 You can see the context of a file using the -Z option to ls
157 Policy governs the access confined processes have to these files.
159 SELinux memcached policy is very flexible allowing users to setup their
160 memcached processes in as secure a method as possible.
161 STANDARD FILE CONTEXT
163 SELinux defines the file context types for the memcached, if you wanted
165 to store files with these types in a diffent paths, you need to execute
166 the semanage command to specify alternate labeling and then use re‐
167 storecon to put the labels on disk.
168 semanage fcontext -a -t memcached_var_run_t '/srv/mymemcached_con‐
170 tent(/.*)?'
171 restorecon -R -v /srv/mymemcached_content
172 Note: SELinux often uses regular expressions to specify labels that
174 match multiple files.
175 The following file types are defined for memcached:
177 memcached_exec_t
181 - Set files with the memcached_exec_t type, if you want to transition
183 an executable to the memcached_t domain.
184 memcached_initrc_exec_t
188 - Set files with the memcached_initrc_exec_t type, if you want to tran‐
190 sition an executable to the memcached_initrc_t domain.
191 memcached_var_run_t
195 - Set files with the memcached_var_run_t type, if you want to store the
197 memcached files under the /run or /var/run directory.
198 Paths:
201 /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
202 Note: File context can be temporarily modified with the chcon command.
205 If you want to permanently change the file context you need to use the
206 semanage fcontext command. This will modify the SELinux labeling data‐
207 base. You will need to use restorecon to apply the labels.
208
211 semanage fcontext can also be used to manipulate default file context
212 mappings.
213 semanage permissive can also be used to manipulate whether or not a
215 process type is permissive.
216 semanage module can also be used to enable/disable/install/remove pol‐
218 icy modules.
219 semanage port can also be used to manipulate the port definitions
221 semanage boolean can also be used to manipulate the booleans
223 system-config-selinux is a GUI tool available to customize SELinux pol‐
226 icy settings.
