Security-Enhanced Linux secures the zarafa_deliver processes via flexible mandatory access control.
The zarafa_deliver processes execute with the zarafa_deliver_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep zarafa_deliver_t
The zarafa_deliver_t SELinux type can be entered via the zarafa_deliver_exec_t file type.
The default entrypoint paths for the zarafa_deliver_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 zarafa_deliver policy is very flexible allowing users to setup their zarafa_deliver processes in as secure a method as possible.
The following process types are defined for zarafa_deliver:
Note: semanage permissive -a zarafa_deliver_t can be used to make the process type zarafa_deliver_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. zarafa_deliver policy is extremely flexible and has several booleans that allow you to manipulate the policy and run zarafa_deliver with the tightest access possible.
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 zarafa domains to setrlimit/sys_resource, you must turn on the zarafa_setrlimit boolean. Disabled by default.
setsebool -P zarafa_setrlimit 1
The SELinux process type zarafa_deliver_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 zarafa_deliver policy is very flexible allowing users to setup their zarafa_deliver processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the zarafa_deliver, if you wanted to store files with these types in a diffent 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 zarafa_deliver_exec_t '/srv/zarafa_deliver/content(/.*)?'
restorecon -R -v /srv/myzarafa_deliver_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for zarafa_deliver:
- Set files with the zarafa_deliver_exec_t type, if you want to transition an executable to the zarafa_deliver_t domain.
- Set files with the zarafa_deliver_log_t type, if you want to treat the data as zarafa deliver log data, usually stored under the /var/log directory.
- Set files with the zarafa_deliver_tmp_t type, if you want to store zarafa deliver temporary files in the /tmp directories.
- Set files with the zarafa_deliver_var_run_t type, if you want to store the zarafa deliver 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 boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
