NAME

snort_selinux - Security Enhanced Linux Policy for the snort processes

DESCRIPTION

SELinux Linux secures snort (Snort network intrusion detection system) processes via flexible mandatory access control.

FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux snort policy is very flexible allowing users to setup their snort processes in as secure a method as possible.

The following file types are defined for snort:

snort_etc_t

- Set files with the snort_etc_t type, if you want to store snort files in the /etc directories.

snort_exec_t

- Set files with the snort_exec_t type, if you want to transition an executable to the snort_t domain.

Paths:: /usr/sbin/snort-plain, /usr/s?bin/snort

snort_initrc_exec_t

- Set files with the snort_initrc_exec_t type, if you want to transition an executable to the snort_initrc_t domain.

snort_log_t

- Set files with the snort_log_t type, if you want to treat the data as snort log data, usually stored under the /var/log directory.

snort_tmp_t

- Set files with the snort_tmp_t type, if you want to store snort temporary files in the /tmp directories.

snort_var_run_t

- Set files with the snort_var_run_t type, if you want to store the snort files under the /run directory.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

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 psP Policy governs the access confined processes have to files. SELinux snort policy is very flexible allowing users to setup their snort processes in as secure a method as possible.

The following process types are defined for snort:

snort_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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.

system-config-selinux is a GUI tool available to customize SELinux policy settings.
