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
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 admin_crontab policy is very flexible allowing users to setup their
40 admin_crontab processes in as secure a method as possible.
41
42 The following process types are defined for admin_crontab:
43
44 admin_crontab_t
45
46 Note: semanage permissive -a admin_crontab_t can be used to make the
47 process type admin_crontab_t permissive. SELinux does not deny access
48 to 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 admin_crontab policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run admin_crontab with the
56 tightest access possible.

59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69
70 setsebool -P allow_kerberos 1
71
72
73
74 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76
77 setsebool -P allow_ptrace 1
78
79
80
81 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83
84 setsebool -P allow_ypbind 1
85
86
87
88 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91
92 setsebool -P domain_kernel_load_modules 1
93
94
95
96 If you want to enable extra rules in the cron domain to support fcron,
97 you must turn on the fcron_crond boolean. Disabled by default.
98
99 setsebool -P fcron_crond 1
100
101
102
103 If you want to allow all domains to execute in fips_mode, you must turn
104 on the fips_mode boolean. Enabled by default.
105
106 setsebool -P fips_mode 1
107
108
109
110 If you want to enable reading of urandom for all domains, you must turn
111 on the global_ssp boolean. Disabled by default.
112
113 setsebool -P global_ssp 1
114
115
116
117 If you want to allow confined applications to use nscd shared memory,
118 you must turn on the nscd_use_shm boolean. Enabled by default.
119
120 setsebool -P nscd_use_shm 1
121
122
123
124 If you want to support NFS home directories, you must turn on the
125 use_nfs_home_dirs boolean. Disabled by default.
126
127 setsebool -P use_nfs_home_dirs 1
128
129
130
131 If you want to support SAMBA home directories, you must turn on the
132 use_samba_home_dirs boolean. Disabled by default.
133
134 setsebool -P use_samba_home_dirs 1

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