6 courier_sqwebmail_selinux - Security Enhanced Linux Policy for the
7 courier_sqwebmail processes
8
10 Security-Enhanced Linux secures the courier_sqwebmail processes via
11 flexible mandatory access control.
12 The courier_sqwebmail processes execute with the courier_sqwebmail_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 For example:
18 ps -eZ | grep courier_sqwebmail_t
20
24 The courier_sqwebmail_t SELinux type can be entered via the
25 courier_sqwebmail_exec_t file type.
26 The default entrypoint paths for the courier_sqwebmail_t domain are the
28 following:
29 /usr/lib/courier/sqwebmail/cleancache.pl
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 courier_sqwebmail policy is very flexible allowing users to setup their
40 courier_sqwebmail processes in as secure a method as possible.
41 The following process types are defined for courier_sqwebmail:
43 courier_sqwebmail_t
45 Note: semanage permissive -a courier_sqwebmail_t can be used to make
47 the process type courier_sqwebmail_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
53 SELinux policy is customizable based on least access required.
54 courier_sqwebmail policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run courier_sqwebmail with
56 the tightest access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the daemons_dump_core boolean. Disabled by default.
62 setsebool -P daemons_dump_core 1
64 If you want to enable cluster mode for daemons, you must turn on the
68 daemons_enable_cluster_mode boolean. Enabled by default.
69 setsebool -P daemons_enable_cluster_mode 1
71 If you want to allow all daemons to use tcp wrappers, you must turn on
75 the daemons_use_tcp_wrapper boolean. Disabled by default.
76 setsebool -P daemons_use_tcp_wrapper 1
78 If you want to allow all daemons the ability to read/write terminals,
82 you must turn on the daemons_use_tty boolean. Disabled by default.
83 setsebool -P daemons_use_tty 1
85 If you want to deny any process from ptracing or debugging any other
89 processes, you must turn on the deny_ptrace boolean. Enabled by
90 default.
91 setsebool -P deny_ptrace 1
93 If you want to allow any process to mmap any file on system with
97 attribute file_type, you must turn on the domain_can_mmap_files bool‐
98 ean. Enabled by default.
99 setsebool -P domain_can_mmap_files 1
101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

142 The SELinux process type courier_sqwebmail_t can manage files labeled
143 with the following file types. The paths listed are the default paths
144 for these file types. Note the processes UID still need to have DAC
145 permissions.

188 SELinux requires files to have an extended attribute to define the file
189 type.
190 You can see the context of a file using the -Z option to ls
192 Policy governs the access confined processes have to these files.
194 SELinux courier_sqwebmail policy is very flexible allowing users to
195 setup their courier_sqwebmail processes in as secure a method as possi‐
196 ble.
197 The following file types are defined for courier_sqwebmail:
199 courier_sqwebmail_exec_t
203 - Set files with the courier_sqwebmail_exec_t type, if you want to
205 transition an executable to the courier_sqwebmail_t domain.
206 Note: File context can be temporarily modified with the chcon command.
210 If you want to permanently change the file context you need to use the
211 semanage fcontext command. This will modify the SELinux labeling data‐
212 base. You will need to use restorecon to apply the labels.
213
216 semanage fcontext can also be used to manipulate default file context
217 mappings.
218 semanage permissive can also be used to manipulate whether or not a
220 process type is permissive.
221 semanage module can also be used to enable/disable/install/remove pol‐
223 icy modules.
224 semanage boolean can also be used to manipulate the booleans
226 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
