6 webadm_r - Web administrator role. - Security Enhanced Linux Policy
7
10 SELinux supports Roles Based Access Control (RBAC), some Linux roles
11 are login roles, while other roles need to be transition into.
12 Note: Examples in this man page will use the staff_u SELinux user.
14 Non login roles are usually used for administrative tasks. For example,
16 tasks that require root privileges. Roles control which types a user
17 can run processes with. Roles often have default types assigned to
18 them.
19 The default type for the webadm_r role is webadm_t.
21 The newrole program to transition directly to this role.
23 newrole -r webadm_r -t webadm_t
25 sudo is the preferred method to do transition from one role to another.
27 You setup sudo to transition to webadm_r by adding a similar line to
28 the /etc/sudoers file.
29 USERNAME ALL=(ALL) ROLE=webadm_r TYPE=webadm_t COMMAND
31 sudo will run COMMAND as staff_u:webadm_r:webadm_t:LEVEL
33 When using a a non login role, you need to setup SELinux so that your
35 SELinux user can reach webadm_r role.
36 Execute the following to see all of the assigned SELinux roles:
38 semanage user -l
40 You need to add webadm_r to the staff_u user. You could setup the
42 staff_u user to be able to use the webadm_r role with a command like:
43 $ semanage user -m -R 'staff_r system_r webadm_r' staff_u

49 SELinux policy is customizable based on least access required. webadm
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run webadm with the tightest access possible.
52 If you want to determine whether webadm can manage generic user files,
56 you must turn on the webadm_manage_user_files boolean. Disabled by
57 default.
58 setsebool -P webadm_manage_user_files 1
60 If you want to determine whether webadm can read generic user files,
64 you must turn on the webadm_read_user_files boolean. Disabled by
65 default.
66 setsebool -P webadm_read_user_files 1
68 If you want to allow users to resolve user passwd entries directly from
72 ldap rather then using a sssd server, you must turn on the authlo‐
73 gin_nsswitch_use_ldap boolean. Disabled by default.
74 setsebool -P authlogin_nsswitch_use_ldap 1
76 If you want to deny user domains applications to map a memory region as
80 both executable and writable, this is dangerous and the executable
81 should be reported in bugzilla, you must turn on the deny_execmem bool‐
82 ean. Enabled by default.
83 setsebool -P deny_execmem 1
85 If you want to deny any process from ptracing or debugging any other
89 processes, you must turn on the deny_ptrace boolean. Enabled by
90 default.
91 setsebool -P deny_ptrace 1
93 If you want to allow any process to mmap any file on system with
97 attribute file_type, you must turn on the domain_can_mmap_files bool‐
98 ean. Enabled by default.
99 setsebool -P domain_can_mmap_files 1
101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1
138 If you want to allow confined applications to run with kerberos, you
142 must turn on the kerberos_enabled boolean. Enabled by default.
143 setsebool -P kerberos_enabled 1
145 If you want to allow logging in and using the system from /dev/console,
149 you must turn on the login_console_enabled boolean. Enabled by default.
150 setsebool -P login_console_enabled 1
152 If you want to allow system to run with NIS, you must turn on the
156 nis_enabled boolean. Disabled by default.
157 setsebool -P nis_enabled 1
159 If you want to allow confined applications to use nscd shared memory,
163 you must turn on the nscd_use_shm boolean. Disabled by default.
164 setsebool -P nscd_use_shm 1
166 If you want to disallow programs, such as newrole, from transitioning
170 to administrative user domains, you must turn on the secure_mode bool‐
171 ean. Enabled by default.
172 setsebool -P secure_mode 1
174 If you want to allow unconfined executables to make their stack exe‐
178 cutable. This should never, ever be necessary. Probably indicates a
179 badly coded executable, but could indicate an attack. This executable
180 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
181 stack boolean. Enabled by default.
182 setsebool -P selinuxuser_execstack 1
184 If you want to allow ssh logins as sysadm_r:sysadm_t, you must turn on
188 the ssh_sysadm_login boolean. Disabled by default.
189 setsebool -P ssh_sysadm_login 1
191 If you want to allow the graphical login program to login directly as
195 sysadm_r:sysadm_t, you must turn on the xdm_sysadm_login boolean. Dis‐
196 abled by default.
197 setsebool -P xdm_sysadm_login 1
199
203 The SELinux process type webadm_t can manage files labeled with the
204 following file types. The paths listed are the default paths for these
205 file types. Note the processes UID still need to have DAC permissions.

340 semanage fcontext can also be used to manipulate default file context
341 mappings.
342 semanage permissive can also be used to manipulate whether or not a
344 process type is permissive.
345 semanage module can also be used to enable/disable/install/remove pol‐
347 icy modules.
348 semanage boolean can also be used to manipulate the booleans
350 system-config-selinux is a GUI tool available to customize SELinux pol‐
353 icy settings.
