6 postfix_postqueue_selinux - Security Enhanced Linux Policy for the
7 postfix_postqueue processes
8
10 Security-Enhanced Linux secures the postfix_postqueue processes via
11 flexible mandatory access control.
12
13 The postfix_postqueue processes execute with the postfix_postqueue_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 postfix_postqueue_t
20
21
22
24 The postfix_postqueue_t SELinux type can be entered via the post‐
25 fix_postqueue_exec_t file type.
26
27 The default entrypoint paths for the postfix_postqueue_t domain are the
28 following:
29
30 /usr/sbin/postqueue
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 postfix_postqueue policy is very flexible allowing users to setup their
40 postfix_postqueue processes in as secure a method as possible.
41
42 The following process types are defined for postfix_postqueue:
43
44 postfix_postqueue_t
45
46 Note: semanage permissive -a postfix_postqueue_t can be used to make
47 the process type postfix_postqueue_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required. post‐
54 fix_postqueue policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run postfix_postqueue with
56 the tightest access 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
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 postfix_postqueue_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.
79
80 anon_inodefs_t
81
82
83 postfix_var_run_t
84
85 /var/spool/postfix/pid/.*
86
87
89 SELinux requires files to have an extended attribute to define the file
90 type.
91
92 You can see the context of a file using the -Z option to ls
93
94 Policy governs the access confined processes have to these files.
95 SELinux postfix_postqueue policy is very flexible allowing users to
96 setup their postfix_postqueue processes in as secure a method as possi‐
97 ble.
98
99 The following file types are defined for postfix_postqueue:
100
101
102
103 postfix_postqueue_exec_t
104
105 - Set files with the postfix_postqueue_exec_t type, if you want to
106 transition an executable to the postfix_postqueue_t domain.
107
108
109
110 Note: File context can be temporarily modified with the chcon command.
111 If you want to permanently change the file context you need to use the
112 semanage fcontext command. This will modify the SELinux labeling data‐
113 base. You will need to use restorecon to apply the labels.
114
115
117 semanage fcontext can also be used to manipulate default file context
118 mappings.
119
120 semanage permissive can also be used to manipulate whether or not a
121 process type is permissive.
122
123 semanage module can also be used to enable/disable/install/remove pol‐
124 icy modules.
125
126 semanage boolean can also be used to manipulate the booleans
127
128
129 system-config-selinux is a GUI tool available to customize SELinux pol‐
130 icy settings.
