about the steps to Ethernet security, which provides advice on good security practices. The trend toward using Ethernet as the sole communications network for business and industry has raised concerns about security. While proprietary networks for building or factory automation have major drawbacks in terms of limiting information flow and higher cost, their separation from other systems provides a measure of protection against unauthorized access.

So how do you take advantage of the benefits of Ethernet connectivity within a secure environment? A comprehensive security plan must protect against unauthorized access from both internal and external sources. Methods of security can range from technologies based within the infrastructure itself such as physical connection paths and Virtual Local Area Networks (VLANs) to hardware and software-based devices such as firewalls and security management servers.
