NAMEshorewall_selinux − Security Enhanced Linux Policy for the shorewall processes

DESCRIPTIONSecurity-Enhanced Linux secures the shorewall processes via flexible mandatory access control. The shorewall processes execute with the shorewall_t SELinux type. You can check if you have these processes running by executing the ps command with the −Z qualifier. For example: ps -eZ | grep shorewall_t

ENTRYPOINTSThe shorewall_t SELinux type can be entered via the shorewall_exec_t, shorewall_var_lib_t file types. The default entrypoint paths for the shorewall_t domain are the following: /sbin/shorewall6?, /usr/sbin/shorewall6?, /sbin/shorewall-lite, /usr/sbin/shorewall-lite, /var/lib/shorewall(/.*)?, /var/lib/shorewall6(/.*)?, /var/lib/shorewall-lite(/.*)?

PROCESS TYPESSELinux defines process types (domains) for each process running on the system You can see the context of a process using the −Z option to ps Policy governs the access confined processes have to files. SELinux shorewall policy is very flexible allowing users to setup their shorewall processes in as secure a method as possible. The following process types are defined for shorewall: shorewall_tNote: semanage permissive -a shorewall_t can be used to make the process type shorewall_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANSSELinux policy is customizable based on least access required. shorewall policy is extremely flexible and has several booleans that allow you to manipulate the policy and run shorewall 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 system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default. setsebool -P nis_enabled 1

MANAGED FILESThe SELinux process type shorewall_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.

FILE CONTEXTSSELinux 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 ls Policy governs the access confined processes have to these files. SELinux shorewall policy is very flexible allowing users to setup their shorewall processes in as secure a method as possible. EQUIVALENCE DIRECTORIES shorewall policy stores data with multiple different file context types under the /var/lib/shorewall directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command: semanage fcontext -a -e /var/lib/shorewall /srv/shorewall
restorecon -R -v /srv/shorewall STANDARD FILE CONTEXT SELinux defines the file context types for the shorewall, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk. semanage fcontext -a -t shorewall_log_t '/srv/myshorewall_content(/.*)?'
restorecon -R -v /srv/myshorewall_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for shorewall: shorewall_etc_t- Set files with the shorewall_etc_t type, if you want to store shorewall files in the /etc directories.
Paths: /etc/shorewall(/.*)?, /etc/shorewall6(/.*)?, /etc/shorewall-lite(/.*)? shorewall_exec_t- Set files with the shorewall_exec_t type, if you want to transition an executable to the shorewall_t domain.
Paths: /sbin/shorewall6?, /usr/sbin/shorewall6?, /sbin/shorewall-lite, /usr/sbin/shorewall-lite shorewall_initrc_exec_t- Set files with the shorewall_initrc_exec_t type, if you want to transition an executable to the shorewall_initrc_t domain. shorewall_lock_t- Set files with the shorewall_lock_t type, if you want to treat the files as shorewall lock data, stored under the /var/lock directory shorewall_log_t- Set files with the shorewall_log_t type, if you want to treat the data as shorewall log data, usually stored under the /var/log directory. shorewall_tmp_t- Set files with the shorewall_tmp_t type, if you want to store shorewall temporary files in the /tmp directories. shorewall_var_lib_t- Set files with the shorewall_var_lib_t type, if you want to store the shorewall files under the /var/lib directory.
Paths: /var/lib/shorewall(/.*)?, /var/lib/shorewall6(/.*)?, /var/lib/shorewall-lite(/.*)? 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.

COMMANDSsemanage 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.
