6 admin_crontab_selinux - Security Enhanced Linux Policy for the
7 admin_crontab processes
8
10 Security-Enhanced Linux secures the admin_crontab processes via flexi‐
11 ble mandatory access control.
12
13 The admin_crontab processes execute with the admin_crontab_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep admin_crontab_t
20
21
22
24 The admin_crontab_t SELinux type can be entered via the crontab_exec_t
25 file type.
26
27 The default entrypoint paths for the admin_crontab_t domain are the
28 following:
29
30 /usr/bin/(f)?crontab, /usr/bin/at, /usr/sbin/fcronsighup,
31 /usr/libexec/fcronsighup
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 admin_crontab policy is very flexible allowing users to setup their
41 admin_crontab processes in as secure a method as possible.
42
43 The following process types are defined for admin_crontab:
44
45 admin_crontab_t
46
47 Note: semanage permissive -a admin_crontab_t can be used to make the
48 process type admin_crontab_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
52
54 SELinux policy is customizable based on least access required.
55 admin_crontab policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run admin_crontab with the
57 tightest access possible.

61 If you want to allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64
65 setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69 If you want to enable extra rules in the cron domain to support fcron,
70 you must turn on the fcron_crond boolean. Disabled by default.
71
72 setsebool -P fcron_crond 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to allow confined applications to run with kerberos, you
84 must turn on the kerberos_enabled boolean. Enabled by default.
85
86 setsebool -P kerberos_enabled 1
87
88
89
90 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92
93 setsebool -P nis_enabled 1
94
95
96
97 If you want to allow confined applications to use nscd shared memory,
98 you must turn on the nscd_use_shm boolean. Enabled by default.
99
100 setsebool -P nscd_use_shm 1

105 The SELinux process type admin_crontab_t can manage files labeled with
106 the following file types. The paths listed are the default paths for
107 these file types. Note the processes UID still need to have DAC per‐
108 missions.

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
172
173 system-config-selinux is a GUI tool available to customize SELinux pol‐
174 icy settings.
