IEC 62351 - An Energy Business Necessity

IEC 62351 Security

Excellent security, but do not leave the back door open!!

Utility companies spend a lot of their resources on avoiding cyber-attacks. And rightly so! Because an intruder in a utility network can easily disrupt society, causing tremendous damage. This is why the security features of firewalls, control centers and WANs are reviewed by experts, and why intruder detection systems are installed.

But what is the purpose of installing safe locks on your front door, when you leave your back door open?

And this is exactly what most utility companies still do!  While securing the WAN and the central features, utility companies use unsecured and unencrypted protocols within their substations. With legacy protocols, 5-104 or “bare” IEC 61850, a simple protocol analyzer is able to read login ids and passwords, and all commands to substation components can be monitored and manipulated.

That is why the IEC (International Electrotechnical Commission) gave IEC 62351, the secure authentication and encrypted exchange of IEC 61850, such a high priority. With an easy add-on to the IEC 61850 protocol stack, the backdoor is now locked, making it impossible for physical intruders in the substation to manipulate the substation network management.

The Xelas Energy Software servers, clients, protocols, and mediations offer secure IEC based communication, based on the IEC61351 standard. Our software supports all the defined operations, so open interoperability is assured. And the backdoor remains locked…
