6 postfix_showq_selinux - Security Enhanced Linux Policy for the post‐
7 fix_showq processes
8
10 Security-Enhanced Linux secures the postfix_showq processes via flexi‐
11 ble mandatory access control.
12 The postfix_showq processes execute with the postfix_showq_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep postfix_showq_t
20
24 The postfix_showq_t SELinux type can be entered via the post‐
25 fix_showq_exec_t file type.
26 The default entrypoint paths for the postfix_showq_t domain are the
28 following:
29 /usr/libexec/postfix/showq
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 postfix_showq policy is very flexible allowing users to setup their
40 postfix_showq processes in as secure a method as possible.
41 The following process types are defined for postfix_showq:
43 postfix_showq_t
45 Note: semanage permissive -a postfix_showq_t can be used to make the
47 process type postfix_showq_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. post‐
54 fix_showq policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run postfix_showq with the
56 tightest access possible.
57 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 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type postfix_showq_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.
79 anon_inodefs_t
81 postfix_var_run_t
84 /var/spool/postfix/pid/.*
86
89 SELinux requires files to have an extended attribute to define the file
90 type.
91 You can see the context of a file using the -Z option to ls
93 Policy governs the access confined processes have to these files.
95 SELinux postfix_showq policy is very flexible allowing users to setup
96 their postfix_showq processes in as secure a method as possible.
97 The following file types are defined for postfix_showq:
99 postfix_showq_exec_t
103 - Set files with the postfix_showq_exec_t type, if you want to transi‐
105 tion an executable to the postfix_showq_t domain.
106 Note: File context can be temporarily modified with the chcon command.
110 If you want to permanently change the file context you need to use the
111 semanage fcontext command. This will modify the SELinux labeling data‐
112 base. You will need to use restorecon to apply the labels.
113
116 semanage fcontext can also be used to manipulate default file context
117 mappings.
118 semanage permissive can also be used to manipulate whether or not a
120 process type is permissive.
121 semanage module can also be used to enable/disable/install/remove pol‐
123 icy modules.
124 semanage boolean can also be used to manipulate the booleans
126 system-config-selinux is a GUI tool available to customize SELinux pol‐
129 icy settings.
