Ethernet Security, Safety Relies on Common Sense Networking Ethernet Security, Safety Relies on Common Sense Networking Ethernet-based and other networks face security challenges from external, internal, intentional, and accidental sources, but users are adopting solutions that can protect against intrusions and mishaps. A little less freedom. More users are seeking to gain Ethernet s interoperability and flexibility. However, the relatively greater openness of Ethernet can mean increased network vulnerability, especially when networks are linked via the Internet.
Hazards range from internal data traffic accidents to external hacker attacks.
To prevent potential problems, users can perform several basic precautions as they design, install, and operate their Ethernet-based networks. The good news is that, because Ethernet has been used in other settings for 15 to 20 years, many security measures exist that manufacturing can use as well. Manufacturing had been accustomed to generally closed networks, but many engineers are now becoming enamoured of the information they can get from more open systems. Restricting access probably just seems counterintuitive when you re trying to open a system up. Ethernet aids interoperability by eliminating former barriers, but it also reduces isolation and some of the security that used to be taken for granted.
