6 checkpolicy_selinux - Security Enhanced Linux Policy for the checkpol‐
7 icy processes
8
10 Security-Enhanced Linux secures the checkpolicy processes via flexible
11 mandatory access control.
12
13 The checkpolicy processes execute with the checkpolicy_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 checkpolicy_t
20
21
22
24 The checkpolicy_t SELinux type can be entered via the checkpol‐
25 icy_exec_t file type.
26
27 The default entrypoint paths for the checkpolicy_t domain are the fol‐
28 lowing:
29
30 /usr/bin/checkpolicy
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 checkpolicy policy is very flexible allowing users to setup their
40 checkpolicy processes in as secure a method as possible.
41
42 The following process types are defined for checkpolicy:
43
44 checkpolicy_t
45
46 Note: semanage permissive -a checkpolicy_t can be used to make the
47 process type checkpolicy_t permissive. SELinux does not deny access to
48 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. check‐
54 policy policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run checkpolicy with the tightest ac‐
56 cess possible.
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
68 The SELinux process type checkpolicy_t can manage files labeled with
69 the following file types. The paths listed are the default paths for
70 these file types. Note the processes UID still need to have DAC per‐
71 missions.
72
73 semanage_store_t
74
75 /etc/selinux/([^/]*/)?policy(/.*)?
76 /etc/selinux/(minimum|mls|targeted)/active(/.*)?
77 /etc/selinux/([^/]*/)?modules/(active|tmp|previous)(/.*)?
78 /var/lib/selinux(/.*)?
79 /etc/share/selinux/mls(/.*)?
80 /etc/share/selinux/targeted(/.*)?
81
82
84 SELinux requires files to have an extended attribute to define the file
85 type.
86
87 You can see the context of a file using the -Z option to ls
88
89 Policy governs the access confined processes have to these files.
90 SELinux checkpolicy policy is very flexible allowing users to setup
91 their checkpolicy processes in as secure a method as possible.
92
93 STANDARD FILE CONTEXT
94
95 SELinux defines the file context types for the checkpolicy, if you
96 wanted to store files with these types in a different paths, you need
97 to execute the semanage command to specify alternate labeling and then
98 use restorecon to put the labels on disk.
99
100 semanage fcontext -a -t checkpolicy_exec_t '/srv/checkpolicy/con‐
101 tent(/.*)?'
102 restorecon -R -v /srv/mycheckpolicy_content
103
104 Note: SELinux often uses regular expressions to specify labels that
105 match multiple files.
106
107 The following file types are defined for checkpolicy:
108
109
110
111 checkpolicy_exec_t
112
113 - Set files with the checkpolicy_exec_t type, if you want to transition
114 an executable to the checkpolicy_t domain.
115
116
117
118 Note: File context can be temporarily modified with the chcon command.
119 If you want to permanently change the file context you need to use the
120 semanage fcontext command. This will modify the SELinux labeling data‐
121 base. You will need to use restorecon to apply the labels.
122
123
125 semanage fcontext can also be used to manipulate default file context
126 mappings.
127
128 semanage permissive can also be used to manipulate whether or not a
129 process type is permissive.
130
131 semanage module can also be used to enable/disable/install/remove pol‐
132 icy modules.
133
134 semanage boolean can also be used to manipulate the booleans
135
136
137 system-config-selinux is a GUI tool available to customize SELinux pol‐
138 icy settings.
