NAME

lsassd_selinux - Security Enhanced Linux Policy for the lsassd processes

DESCRIPTION

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

NSSWITCH DOMAIN

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 lsassd policy is very flexible allowing users to setup their lsassd processes in as secure a method as possible.

The following file types are defined for lsassd:

lsassd_exec_t

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

lsassd_tmp_t

- Set files with the lsassd_tmp_t type, if you want to store lsassd temporary files in the /tmp directories.

lsassd_var_lib_t

- Set files with the lsassd_var_lib_t type, if you want to store the lsassd files under the /var/lib directory.

Paths:: /var/lib/likewise-open/krb5ccr_lsass, /var/lib/likewise-open/db/lsass-adstate.filedb, /var/lib/likewise-open/lsasd.err, /var/lib/likewise-open/db/lsass-adcache.db, /var/lib/likewise-open/db/sam.db

lsassd_var_run_t

- Set files with the lsassd_var_run_t type, if you want to store the lsassd files under the /run directory.

lsassd_var_socket_t

- Set files with the lsassd_var_socket_t type, if you want to treat the files as lsassd var socket data.

Paths:: /var/lib/likewise-open/rpc/lsass, /var/lib/likewise-open/.lsassd, /var/lib/likewise-open/.ntlmd

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.

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 lsassd policy is very flexible allowing users to setup their lsassd processes in as secure a method as possible.

The following process types are defined for lsassd:

lsassd_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

MANAGED FILES

The SELinux user type lsassd_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.
