6 sysadm_sudo_selinux - Security Enhanced Linux Policy for the
7 sysadm_sudo processes
8
10 Security-Enhanced Linux secures the sysadm_sudo processes via flexible
11 mandatory access control.
12
13 The sysadm_sudo processes execute with the sysadm_sudo_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sysadm_sudo_t
20
21
22
24 The sysadm_sudo_t SELinux type can be entered via the sudo_exec_t file
25 type.
26
27 The default entrypoint paths for the sysadm_sudo_t domain are the fol‐
28 lowing:
29
30 /usr/bin/sudo(edit)?
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 sysadm_sudo policy is very flexible allowing users to setup their
40 sysadm_sudo processes in as secure a method as possible.
41
42 The following process types are defined for sysadm_sudo:
43
44 sysadm_sudo_t
45
46 Note: semanage permissive -a sysadm_sudo_t can be used to make the
47 process type sysadm_sudo_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 sysadm_sudo policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sysadm_sudo with the tight‐
56 est access possible.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type sysadm_sudo_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.

197 mappings.

199 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.

202 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
