Security Enhanced Linux Policy for the couchdb processes
Security-Enhanced Linux secures the couchdb processes via flexible mandatory access control.
The couchdb processes execute with the couchdb_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep couchdb_t
The couchdb_t SELinux type can be entered via the couchdb_exec_t file type.
The default entrypoint paths for the couchdb_t domain are the following:
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psbP
Policy governs the access confined processes have to files. SELinux couchdb policy is very flexible allowing users to setup their couchdb processes in as secure a method as possible.
The following process types are defined for couchdb:
Note: semanage permissive -a couchdb_t can be used to make the process type couchdb_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. couchdb policy is extremely flexible and has several booleans that allow you to manipulate the policy and run couchdb with the tightest access possible.
If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.
setsebool -P daemons_dontaudit_scheduling 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
SELinux defines port types to represent TCP and UDP ports.
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 couchdb policy is very flexible allowing users to setup their couchdb processes in as secure a method as possible.
The following port types are defined for couchdb:
Default Defined Ports: tcp 5984,6984 udp 5984,6984
The SELinux process type couchdb_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.
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsbP
Policy governs the access confined processes have to these files. SELinux couchdb policy is very flexible allowing users to setup their couchdb processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the couchdb, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t couchdb_exec_t '/srv/couchdb/content(/.*)?'
restorecon -R -v /srv/mycouchdb_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for couchdb:
- Set files with the couchdb_conf_t type, if you want to treat the files as couchdb configuration data, usually stored under the /etc directory.
- Set files with the couchdb_exec_t type, if you want to transition an executable to the couchdb_t domain.
- Set files with the couchdb_initrc_exec_t type, if you want to transition an executable to the couchdb_initrc_t domain.
- Set files with the couchdb_log_t type, if you want to treat the data as couchdb log data, usually stored under the /var/log directory.
- Set files with the couchdb_tmp_t type, if you want to store couchdb temporary files in the /tmp directories.
- Set files with the couchdb_unit_file_t type, if you want to treat the files as couchdb unit content.
- Set files with the couchdb_var_lib_t type, if you want to store the couchdb files under the /var/lib directory.
- Set files with the couchdb_var_run_t type, if you want to store the couchdb files under the /run or /var/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.
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
