6 checkpc_selinux - Security Enhanced Linux Policy for the checkpc pro‐
7 cesses
8
10 Security-Enhanced Linux secures the checkpc processes via flexible
11 mandatory access control.
12
13 The checkpc processes execute with the checkpc_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep checkpc_t
20
21
22
24 The checkpc_t SELinux type can be entered via the checkpc_exec_t file
25 type.
26
27 The default entrypoint paths for the checkpc_t domain are the follow‐
28 ing:
29
30 /usr/sbin/checkpc
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 checkpc policy is very flexible allowing users to setup their checkpc
40 processes in as secure a method as possible.
41
42 The following process types are defined for checkpc:
43
44 checkpc_t
45
46 Note: semanage permissive -a checkpc_t can be used to make the process
47 type checkpc_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. checkpc
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run checkpc with the tightest access possi‐
56 ble.
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 allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type checkpc_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.
78
79 print_spool_t
80
81 /var/spool/lpd(/.*)?
82 /var/spool/cups(/.*)?
83 /var/spool/cups-pdf(/.*)?
84
85
87 SELinux requires files to have an extended attribute to define the file
88 type.
89
90 You can see the context of a file using the -Z option to ls
91
92 Policy governs the access confined processes have to these files.
93 SELinux checkpc policy is very flexible allowing users to setup their
94 checkpc processes in as secure a method as possible.
95
96 STANDARD FILE CONTEXT
97
98 SELinux defines the file context types for the checkpc, if you wanted
99 to store files with these types in a diffent paths, you need to execute
100 the semanage command to specify alternate labeling and then use re‐
101 storecon to put the labels on disk.
102
103 semanage fcontext -a -t checkpc_log_t '/srv/mycheckpc_content(/.*)?'
104 restorecon -R -v /srv/mycheckpc_content
105
106 Note: SELinux often uses regular expressions to specify labels that
107 match multiple files.
108
109 The following file types are defined for checkpc:
110
111
112
113 checkpc_exec_t
114
115 - Set files with the checkpc_exec_t type, if you want to transition an
116 executable to the checkpc_t domain.
117
118
119
120 checkpc_log_t
121
122 - Set files with the checkpc_log_t type, if you want to treat the data
123 as checkpc log data, usually stored under the /var/log directory.
124
125
126
127 Note: File context can be temporarily modified with the chcon command.
128 If you want to permanently change the file context you need to use the
129 semanage fcontext command. This will modify the SELinux labeling data‐
130 base. You will need to use restorecon to apply the labels.
131
132
134 semanage fcontext can also be used to manipulate default file context
135 mappings.
136
137 semanage permissive can also be used to manipulate whether or not a
138 process type is permissive.
139
140 semanage module can also be used to enable/disable/install/remove pol‐
141 icy modules.
142
143 semanage boolean can also be used to manipulate the booleans
144
145
146 system-config-selinux is a GUI tool available to customize SELinux pol‐
147 icy settings.
