NAME

cdrecord_selinux - Security Enhanced Linux Policy for the cdrecord processes  

DESCRIPTION

Security-Enhanced Linux secures the cdrecord processes via flexible mandatory access control.

The cdrecord processes execute with the cdrecord_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 cdrecord_t

 

ENTRYPOINTS

The cdrecord_t SELinux type can be entered via the cdrecord_exec_t file type.

The default entrypoint paths for the cdrecord_t domain are the following:

/usr/bin/wodim, /usr/bin/cdrecord, /usr/bin/growisofs  

PROCESS TYPES

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 psP Policy governs the access confined processes have to files. SELinux cdrecord policy is very flexible allowing users to setup their cdrecord processes in as secure a method as possible.

The following process types are defined for cdrecord:

cdrecord_t

Note: semanage permissive -a cdrecord_t can be used to make the process type cdrecord_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

 

BOOLEANS

SELinux policy is customizable based on least access required. cdrecord policy is extremely flexible and has several booleans that allow you to manipulate the policy and run cdrecord with the tightest access possible.

If you want to determine whether cdrecord can read various content. nfs, samba, removable devices, user temp and untrusted content files, you must turn on the cdrecord_read_content boolean. Disabled by default.

setsebool -P cdrecord_read_content 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

 

MANAGED FILES

The SELinux process type cdrecord_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.


cifs_t


ecryptfs_t

        /home/[^/]+/.Private(/.*)?

       /home/[^/]+/.ecryptfs(/.*)?


fusefs_t

        /var/run/user/[^/]*/gvfs


nfs_t

 

FILE CONTEXTS

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 lsP Policy governs the access confined processes have to these files. SELinux cdrecord policy is very flexible allowing users to setup their cdrecord processes in as secure a method as possible.

The following file types are defined for cdrecord:

cdrecord_exec_t

- Set files with the cdrecord_exec_t type, if you want to transition an executable to the cdrecord_t domain.


Paths:
/usr/bin/wodim, /usr/bin/cdrecord, /usr/bin/growisofs

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.

 

COMMANDS

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.
