NAME

6       sysadm_sudo_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       sysadm_sudo processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.
