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 allow webadm to manage files in users home directories,
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 allow webadm to read files in users home directories,
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 direct login to the console device. Required for
72 System 390, you must turn on the allow_console_login boolean. Enabled
73 by default.
74 setsebool -P allow_console_login 1
76 If you want to allow all domains to use other domains file descriptors,
80 you must turn on the allow_domain_fd_use boolean. Enabled by default.
81 setsebool -P allow_domain_fd_use 1
83 If you want to allow unconfined executables to map a memory region as
87 both executable and writable, this is dangerous and the executable
88 should be reported in bugzilla), you must turn on the allow_execmem
89 boolean. Enabled by default.
90 setsebool -P allow_execmem 1
92 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla), you must turn on the allow_execstack
99 boolean. Enabled by default.
100 setsebool -P allow_execstack 1
102 If you want to allow confined applications to run with kerberos, you
106 must turn on the allow_kerberos boolean. Enabled by default.
107 setsebool -P allow_kerberos 1
109 If you want to allow sysadm to debug or ptrace all processes, you must
113 turn on the allow_ptrace boolean. Disabled by default.
114 setsebool -P allow_ptrace 1
116 If you want to allow system to run with NIS, you must turn on the
120 allow_ypbind boolean. Disabled by default.
121 setsebool -P allow_ypbind 1
123 If you want to allow all domains to have the kernel load modules, you
127 must turn on the domain_kernel_load_modules boolean. Disabled by
128 default.
129 setsebool -P domain_kernel_load_modules 1
131 If you want to allow all domains to execute in fips_mode, you must turn
135 on the fips_mode boolean. Enabled by default.
136 setsebool -P fips_mode 1
138 If you want to enable reading of urandom for all domains, you must turn
142 on the global_ssp boolean. Disabled by default.
143 setsebool -P global_ssp 1
145 If you want to allow confined applications to use nscd shared memory,
149 you must turn on the nscd_use_shm boolean. Enabled by default.
150 setsebool -P nscd_use_shm 1
152 If you want to enabling secure mode disallows programs, such as new‐
156 role, from transitioning to administrative user domains, you must turn
157 on the secure_mode boolean. Disabled by default.
158 setsebool -P secure_mode 1
160 If you want to allow ssh logins as sysadm_r:sysadm_t, you must turn on
164 the ssh_sysadm_login boolean. Disabled by default.
165 setsebool -P ssh_sysadm_login 1
167 If you want to allow xdm logins as sysadm, you must turn on the
171 xdm_sysadm_login boolean. Disabled by default.
172 setsebool -P xdm_sysadm_login 1

178 The SELinux process type webadm_t can manage files labeled with the
179 following file types. The paths listed are the default paths for these
180 file types. Note the processes UID still need to have DAC permissions.

300 semanage fcontext can also be used to manipulate default file context
301 mappings.
302 semanage permissive can also be used to manipulate whether or not a
304 process type is permissive.
305 semanage module can also be used to enable/disable/install/remove pol‐
307 icy modules.
308 semanage boolean can also be used to manipulate the booleans
310 system-config-selinux is a GUI tool available to customize SELinux pol‐
313 icy settings.
