6 unconfined_cronjob_selinux - Security Enhanced Linux Policy for the
7 unconfined_cronjob processes
8
10 Security-Enhanced Linux secures the unconfined_cronjob processes via
11 flexible mandatory access control.
12
13 The unconfined_cronjob processes execute with the unconfined_cronjob_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep unconfined_cronjob_t
20
21
22
24 SELinux defines process types (domains) for each process running on the
25 system
26
27 You can see the context of a process using the -Z option to ps
28
29 Policy governs the access confined processes have to files. SELinux
30 unconfined_cronjob policy is very flexible allowing users to setup
31 their unconfined_cronjob processes in as secure a method as possible.
32
33 The following process types are defined for unconfined_cronjob:
34
35 unconfined_cronjob_t
36
37 Note: semanage permissive -a unconfined_cronjob_t can be used to make
38 the process type unconfined_cronjob_t permissive. SELinux does not deny
39 access to permissive process types, but the AVC (SELinux denials) mes‐
40 sages are still generated.
41
42
44 SELinux policy is customizable based on least access required. uncon‐
45 fined_cronjob policy is extremely flexible and has several booleans
46 that allow you to manipulate the policy and run unconfined_cronjob with
47 the tightest access possible.

51 If you want to deny user domains applications to map a memory region as
52 both executable and writable, this is dangerous and the executable
53 should be reported in bugzilla, you must turn on the deny_execmem bool‐
54 ean. Enabled by default.
55
56 setsebool -P deny_execmem 1
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to control the ability to mmap a low area of the address
68 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
69 the mmap_low_allowed boolean. Disabled by default.
70
71 setsebool -P mmap_low_allowed 1
72
73
74
75 If you want to disable kernel module loading, you must turn on the
76 secure_mode_insmod boolean. Enabled by default.
77
78 setsebool -P secure_mode_insmod 1
79
80
81
82 If you want to allow unconfined executables to make their heap memory
83 executable. Doing this is a really bad idea. Probably indicates a
84 badly coded executable, but could indicate an attack. This executable
85 should be reported in bugzilla, you must turn on the selin‐
86 uxuser_execheap boolean. Disabled by default.
87
88 setsebool -P selinuxuser_execheap 1
89
90
91
92 If you want to allow unconfined executables to make their stack exe‐
93 cutable. This should never, ever be necessary. Probably indicates a
94 badly coded executable, but could indicate an attack. This executable
95 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
96 stack boolean. Enabled by default.
97
98 setsebool -P selinuxuser_execstack 1

103 The SELinux process type unconfined_cronjob_t can manage files labeled
104 with the following file types. The paths listed are the default paths
105 for these file types. Note the processes UID still need to have DAC
106 permissions.
107
108 file_type
109
110 all files on the system
111
112
114 semanage fcontext can also be used to manipulate default file context
115 mappings.
116
117 semanage permissive can also be used to manipulate whether or not a
118 process type is permissive.
119
120 semanage module can also be used to enable/disable/install/remove pol‐
121 icy modules.
122
123 semanage boolean can also be used to manipulate the booleans
124
125
126 system-config-selinux is a GUI tool available to customize SELinux pol‐
127 icy settings.
