NAME
courier_sqwebmail_selinux - Security Enhanced Linux Policy for the courier_sqwebmail processes
DESCRIPTION
Security-Enhanced Linux secures the courier_sqwebmail processes via flexible mandatory access control.
The courier_sqwebmail processes execute with the courier_sqwebmail_t SELinux type. You can check if you have these processes running by
executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep courier_sqwebmail_t
ENTRYPOINTS
The courier_sqwebmail_t SELinux type can be entered via the courier_sqwebmail_exec_t file type.
The default entrypoint paths for the courier_sqwebmail_t domain are the following:
PROCESS TYPES
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux courier_sqwebmail policy is very flexible allowing users to setup
their courier_sqwebmail processes in as secure a method as possible.
The following process types are defined for courier_sqwebmail:
courier_sqwebmail_t
Note: semanage permissive -a courier_sqwebmail_t can be used to make the process type courier_sqwebmail_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. courier_sqwebmail policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run courier_sqwebmail with the tightest access possible.
If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1

paths for these file types. Note the processes UID still need to have DAC permissions.

COMMANDS
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
