6 sysadm_su_selinux - Security Enhanced Linux Policy for the sysadm_su
7 processes
8
10 Security-Enhanced Linux secures the sysadm_su processes via flexible
11 mandatory access control.
12
13 The sysadm_su processes execute with the sysadm_su_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sysadm_su_t
20
21
22
24 The sysadm_su_t SELinux type can be entered via the su_exec_t file
25 type.
26
27 The default entrypoint paths for the sysadm_su_t domain are the follow‐
28 ing:
29
30 /usr/(local/)?bin/ksu, /bin/su, /usr/bin/su, /usr/bin/kdesu
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_su policy is very flexible allowing users to setup their
40 sysadm_su processes in as secure a method as possible.
41
42 The following process types are defined for sysadm_su:
43
44 sysadm_su_t, sysadm_sudo_t
45
46 Note: semanage permissive -a sysadm_su_t can be used to make the
47 process type sysadm_su_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_su policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sysadm_su with the tightest
56 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. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type sysadm_su_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

138 semanage fcontext can also be used to manipulate default file context
139 mappings.

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

145 icy modules.
