NAME

       sysadm_su_selinux - Security Enhanced Linux Policy for the sysadm_su processes

DESCRIPTION

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

       The  sysadm_su  processes  execute with the sysadm_su_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 sysadm_su_t

ENTRYPOINTS

       The sysadm_su_t SELinux type can be entered via the su_exec_t file type.

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

       /usr/(local/)?bin/ksu, /bin/su, /usr/bin/su, /usr/bin/kdesu

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

       The following process types are defined for sysadm_su:

       sysadm_su_t, sysadm_sudo_t

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

BOOLEANS

       SELinux policy is customizable based on least access required.  sysadm_su policy is extremely flexible and has several booleans that  allow
       you to manipulate the policy and run sysadm_su 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 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. Disabled by default.

       setsebool -P nscd_use_shm 1

       If you want to enable polyinstantiated directory support, you must turn on the polyinstantiation_enabled boolean. Disabled by default.

       setsebool -P polyinstantiation_enabled 1

       If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.

       setsebool -P use_nfs_home_dirs 1

       If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

       setsebool -P use_samba_home_dirs 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  sysadm_su_t,
       sysadm_sudo_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 sysadm_su_t, sysadm_sudo_t, you must turn on the kerberos_enabled
       boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The SELinux process type sysadm_su_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.

       faillog_t

	    /var/log/btmp.*
	    /var/log/faillog.*
	    /var/log/tallylog.*
	    /var/run/faillock(/.*)?

       initrc_var_run_t

	    /var/run/utmp
	    /var/run/random-seed
	    /var/run/runlevel.dir
	    /var/run/setmixer_flag

       krb5_host_rcache_t

	    /var/cache/krb5rcache(/.*)?
	    /var/tmp/nfs_0
	    /var/tmp/DNS_25
	    /var/tmp/host_0
	    /var/tmp/imap_0
	    /var/tmp/HTTP_23
	    /var/tmp/HTTP_48
	    /var/tmp/ldap_55
	    /var/tmp/ldap_487
	    /var/tmp/ldapmap1_0

       lastlog_t

	    /var/log/lastlog.*

       security_t

	    /selinux

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.
