Security-Enhanced Linux secures the zarafa_ical processes via flexible mandatory access control.
The zarafa_ical processes execute with the zarafa_ical_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_ical_t
The zarafa_ical_t SELinux type can be entered via the zarafa_ical_exec_t file type.
The default entrypoint paths for the zarafa_ical_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_ical policy is very flexible allowing users to setup their zarafa_ical processes in as secure a method as possible.
The following process types are defined for zarafa_ical:
Note: semanage permissive -a zarafa_ical_t can be used to make the process type zarafa_ical_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_ical policy is extremely flexible and has several booleans that allow you to manipulate the policy and run zarafa_ical 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
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_ical_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_ical policy is very flexible allowing users to setup their zarafa_ical processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the zarafa_ical, 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 zarafa_ical_exec_t '/srv/zarafa_ical/content(/.*)?'
restorecon -R -v /srv/myzarafa_ical_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for zarafa_ical:
- Set files with the zarafa_ical_exec_t type, if you want to transition an executable to the zarafa_ical_t domain.
- Set files with the zarafa_ical_log_t type, if you want to treat the data as zarafa ical log data, usually stored under the /var/log directory.
- Set files with the zarafa_ical_var_run_t type, if you want to store the zarafa ical 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.
