TCP Wrapper
TCP Wrapper addresses the inherent security issues with inetd.sec by providing built-in protection
against host name and host address spoofing. It is broadly similar to
inetd.sec in that is uses access
control files to prevent or allow access to services under the control of
inetd and offers additional
functionality.
TCP Wrapper is an Internet Services product available on Software Depot.
