NAME

       sulogin_selinux - Security Enhanced Linux Policy for the sulogin processes

DESCRIPTION

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

       The  sulogin  processes execute with the sulogin_t SELinux type. You can check if you have these processes running by executing the ps com-
       mand with the -Z qualifier.

       For example:

       ps -eZ | grep sulogin_t

ENTRYPOINTS

       The sulogin_t SELinux type can be entered via the sulogin_exec_t file type.

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

       /sbin/sulogin, /sbin/sushell, /usr/sbin/sulogin, /usr/sbin/sushell

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 ps

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

       The following process types are defined for sulogin:

       sulogin_t

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

BOOLEANS

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

       If  you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or debugging any other processes, you must  turn  on  the	deny_ptrace  boolean.  Enabled	by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want  to  allow  all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
       default.

       setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 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 confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

       setsebool -P nscd_use_shm 1

       If you want to allow a user to login as an unconfined domain, you must turn on the unconfined_login boolean. Enabled by default.

       setsebool -P unconfined_login 1

NSSWITCH DOMAIN

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the  sulogin_t,  you  must
       turn on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the sulogin_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The  SELinux  process  type  sulogin_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.

       security_t

	    /selinux

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 ls

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

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the sulogin, if you wanted to store files with these types in a diffent paths, you need to exe-
       cute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t sulogin_exec_t '/srv/sulogin/content(/.*)?'
       restorecon -R -v /srv/mysulogin_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for sulogin:

       sulogin_exec_t

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

       Paths:
	    /sbin/sulogin, /sbin/sushell, /usr/sbin/sulogin, /usr/sbin/sushell

       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.
