NAME

       webadm_r - Web administrator role. - Security Enhanced Linux Policy

DESCRIPTION

       SELinux supports Roles Based Access Control (RBAC), some Linux roles are login roles, while other roles need to be transition into.

       Note: Examples in this man page will use the staff_u SELinux user.

       Non  login  roles  are usually used for administrative tasks. For example, tasks that require root privileges.  Roles control which types a
       user can run processes with. Roles often have default types assigned to them.

       The default type for the webadm_r role is webadm_t.

       The newrole program to transition directly to this role.

       newrole -r webadm_r -t webadm_t

       sudo is the preferred method to do transition from one role to another.	You setup sudo to transition to webadm_r by adding a similar  line
       to the /etc/sudoers file.

       USERNAME ALL=(ALL) ROLE=webadm_r TYPE=webadm_t COMMAND

       sudo will run COMMAND as staff_u:webadm_r:webadm_t:LEVEL

       When using a a non login role, you need to setup SELinux so that your SELinux user can reach webadm_r role.

       Execute the following to see all of the assigned SELinux roles:

       semanage user -l

       You need to add webadm_r to the staff_u user.  You could setup the staff_u user to be able to use the webadm_r role with a command like:

       $ semanage user -m -R 'staff_r system_r webadm_r' staff_u

BOOLEANS

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

       If you want to determine whether webadm can manage generic user files, you must turn on the webadm_manage_user_files boolean.  Disabled	by
       default.

       setsebool -P webadm_manage_user_files 1

       If  you	want  to  determine  whether  webadm can read generic user files, you must turn on the webadm_read_user_files boolean. Disabled by
       default.

       setsebool -P webadm_read_user_files 1

       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 user domains applications to map a memory region as both executable and writable, this is dangerous and the executable
       should be reported in bugzilla, you must turn on the deny_execmem boolean. Enabled by default.

       setsebool -P deny_execmem 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 logging in and using the system from /dev/console, you must turn on  the  login_console_enabled  boolean.  Enabled	by
       default.

       setsebool -P login_console_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  disallow  programs, such as newrole, from transitioning to administrative user domains, you must turn on the secure_mode
       boolean. Enabled by default.

       setsebool -P secure_mode 1

       If you want to allow unconfined executables to make their stack executable.  This should never, ever be	necessary.  Probably  indicates  a
       badly  coded  executable,  but  could  indicate	an  attack.  This  executable  should be reported in bugzilla, you must turn on the selin-
       uxuser_execstack boolean. Enabled by default.

       setsebool -P selinuxuser_execstack 1

       If you want to allow ssh logins as sysadm_r:sysadm_t, you must turn on the ssh_sysadm_login boolean. Disabled by default.

       setsebool -P ssh_sysadm_login 1

       If you want to allow the graphical login program to login directly as sysadm_r:sysadm_t, you must turn  on  the	xdm_sysadm_login  boolean.
       Disabled by default.

       setsebool -P xdm_sysadm_login 1

MANAGED FILES

       The SELinux process type webadm_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.
