NAME

6       unconfined_cronjob_selinux - Security Enhanced Linux Policy for the un‐
7       confined_cronjob processes
8

DESCRIPTION

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

PROCESS TYPES

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.

BOOLEANS

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.

50
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 control the ability to mmap a low area of the address
61       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
62       the mmap_low_allowed boolean. Disabled by default.
63
64       setsebool -P mmap_low_allowed 1
65
66
67
68       If  you want to disable kernel module loading, you must turn on the se‐
69       cure_mode_insmod boolean. Enabled by default.
70
71       setsebool -P secure_mode_insmod 1
72
73
74
75       If you want to allow unconfined executables to make their  heap  memory
76       executable.   Doing  this  is  a  really bad idea. Probably indicates a
77       badly coded executable, but could indicate an attack.  This  executable
78       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
79       echeap boolean. Disabled by default.
80
81       setsebool -P selinuxuser_execheap 1
82
83
84
85       If you want to allow unconfined executables to make  their  stack  exe‐
86       cutable.   This  should  never, ever be necessary. Probably indicates a
87       badly coded executable, but could indicate an attack.  This  executable
88       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
89       stack boolean. Enabled by default.
90
91       setsebool -P selinuxuser_execstack 1

MANAGED FILES

96       The SELinux process type unconfined_cronjob_t can manage files  labeled
97       with  the following file types.  The paths listed are the default paths
98       for these file types.  Note the processes UID still need  to  have  DAC
99       permissions.
100
101       file_type
102
103            all files on the system
104
105

COMMANDS

107       semanage  fcontext  can also be used to manipulate default file context
108       mappings.
109
110       semanage permissive can also be used to manipulate  whether  or  not  a
111       process type is permissive.
112
113       semanage  module can also be used to enable/disable/install/remove pol‐
114       icy modules.
115
116       semanage boolean can also be used to manipulate the booleans
117
118
119       system-config-selinux is a GUI tool available to customize SELinux pol‐
120       icy settings.
