Security-Enhanced Linux secures the mongod processes via flexible mandatory access control.
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux mongod policy is very flexible allowing users to setup their mongod processes in as secure a method as possible.
The following file types are defined for mongod:
mongod_exec_t
- Set files with the mongod_exec_t type, if you want to transition an executable to the mongod_t domain.
mongod_initrc_exec_t
- Set files with the mongod_initrc_exec_t type, if you want to transition an executable to the mongod_initrc_t domain.
mongod_log_t
- Set files with the mongod_log_t type, if you want to treat the data as mongod log data, usually stored under the /var/log directory.
mongod_tmp_t
- Set files with the mongod_tmp_t type, if you want to store mongod temporary files in the /tmp directories.
mongod_var_lib_t
- Set files with the mongod_var_lib_t type, if you want to store the mongod files under the /var/lib directory.
mongod_var_run_t
- Set files with the mongod_var_run_t type, if you want to store the mongod files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux mongod policy is very flexible allowing users to setup their mongod processes in as secure a method as possible.
The following port types are defined for mongod:
Default Defined Ports: tcp 27017
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mongod policy is very flexible allowing users to setup their mongod processes in as secure a method as possible.
The following process types are defined for mongod:
mongod_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
The SELinux user type mongod_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
mongod_log_t
/var/log/mongo(/.*)?
/var/log/mongodb(/.*)?
/var/log/mongo/mongod.log.*
/var/log/aeolus-conductor/dbomatic.log.*
mongod_tmp_t
mongod_var_lib_t
/var/lib/mongodb(/.*)?
mongod_var_run_t
/var/run/mongodb(/.*)?
/var/run/aeolus/dbomatic.pid
semanage permissive can also be used to manipulate whether or not a process type is per
