DESCRIPTION

10       SELinux  supports  Roles  Based Access Control (RBAC), some Linux roles
11       are login roles, while other roles need to be transition into.
12
13       Note: Examples in this man page will use the staff_u SELinux user.
14
15       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
20       The default type for the secadm_r role is secadm_t.
21
22       The newrole program to transition directly to this role.
23
24       newrole -r secadm_r -t secadm_t
25
26       sudo is the preferred method to do transition from one role to another.
27       You setup sudo to transition to secadm_r by adding a  similar  line  to
28       the /etc/sudoers file.
29
30       USERNAME ALL=(ALL) ROLE=secadm_r TYPE=secadm_t COMMAND
31
32       sudo will run COMMAND as staff_u:secadm_r:secadm_t:LEVEL
33
34       When  using  a  non  login role, you need to setup SELinux so that your
35       SELinux user can reach secadm_r role.
36
37       Execute the following to see all of the assigned SELinux roles:
38
39       semanage user -l
40
41       You need to add secadm_r to the staff_u  user.   You  could  setup  the
42       staff_u user to be able to use the secadm_r role with a command like:
43
44       $ semanage user -m -R 'staff_r system_r secadm_r' staff_u
45
46
47
48       SELinux  policy also controls which roles can transition to a different
49       role.  You can list these rules using the following command.
50
51       search --role_allow
52
53       SELinux policy allows the sysadm_r, staff_r, auditadm_r roles can tran‐
54       sition to the secadm_r role.

BOOLEANS

59       SELinux  policy is customizable based on least access required.  secadm
60       policy is extremely flexible and has several booleans that allow you to
61       manipulate the policy and run secadm with the tightest access possible.
62
63
64
65       If you want to deny user domains applications to map a memory region as
66       both executable and writable, this  is  dangerous  and  the  executable
67       should be reported in bugzilla, you must turn on the deny_execmem bool‐
68       ean. Enabled by default.
69
70       setsebool -P deny_execmem 1
71
72
73
74       If you want to deny any process from ptracing or  debugging  any  other
75       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
76       default.
77
78       setsebool -P deny_ptrace 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If  you  want  to  allow  system  to run with NIS, you must turn on the
90       nis_enabled boolean. Disabled by default.
91
92       setsebool -P nis_enabled 1
93
94
95
96       If you want to allow unconfined executables to make  their  stack  exe‐
97       cutable.   This  should  never, ever be necessary. Probably indicates a
98       badly coded executable, but could indicate an attack.  This  executable
99       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
100       stack boolean. Disabled by default.
101
102       setsebool -P selinuxuser_execstack 1

MANAGED FILES

COMMANDS

161       semanage fcontext can also be used to manipulate default  file  context
162       mappings.
163
164       semanage  permissive  can  also  be used to manipulate whether or not a
165       process type is permissive.
166
167       semanage module can also be used to enable/disable/install/remove  pol‐
168       icy modules.
169
170       semanage boolean can also be used to manipulate the booleans
171
