NAME

       sysadm_sudo_selinux - Security Enhanced Linux Policy for the sysadm_sudo processes

DESCRIPTION

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

       The  sysadm_sudo  processes execute with the sysadm_sudo_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_sudo_t

ENTRYPOINTS

       The sysadm_sudo_t SELinux type can be entered via the sudo_exec_t file type.

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

       /usr/bin/sudo(edit)?

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

       The following process types are defined for sysadm_sudo:

       sysadm_sudo_t

       Note:  semanage	permissive -a sysadm_sudo_t can be used to make the process type sysadm_sudo_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.  sysadm_sudo policy is extremely flexible  and  has  several  booleans  that
       allow you to manipulate the policy and run sysadm_sudo 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. Enabled by default.

       setsebool -P nscd_use_shm 1

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

       setsebool -P use_ecryptfs_home_dirs 1

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

       setsebool -P use_fusefs_home_dirs 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_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_sudo_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The  SELinux process type sysadm_sudo_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.

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.
