In this series, we will highlight what cyberspace is and the Coast Guard’s role in cyberspace, generating the service’s first cyberspace operating forces, and modernizing the Coast Guard’s information systems and networks.

Cyberspace is an operational domain for the Coast Guard, and we operate within it just like we do at sea, in the air and on land.
We frequently describe cyberspace as an operational domain, but we don’t always define it. A new video series by Rear Adm. Kevin Lunday, commander, Coast Guard Cyber Command, answers the question, so what is cyberspace?
Think of three layers that stack on top of each other: the physical layer, the logical layer, and the cyber-persona layer:
- The physical layer is the terrain, people and physical network components, like computer and network hardware, routers, telecommunication towers, industrial control systems, and fiber optic cable.
- The logical layer is where data resides in digital format. We can’t see or touch it directly, but we know it’s there.
- The cyber persona layer is the most complex. People are at the physical layer, but each person or entity has many cyber personas. Think of how many email or addresses or logins you have on every website or app that you use.
What makes cyber an operational domain? It’s not the technology; it’s the fact that humans interact, cooperate and engage in competition and conflict in this domain. The result of operations in cyberspace, just like the other domains, ensures that Coast Guard women and men can get the mission done and return safely.
Watch the “Coast Guard Cyber Program 101: Cyberspace is an Operational Domain” video above for more information on the three layers of Cyberspace. The video is also available on: https://www.dvidshub.net/video/531804/cyberspace-operational-domain-coast-guard
Over the next few weeks more episodes of the video series will be released focusing on the Coast Guard’s role in cyberspace, generating the service’s first cyberspace operating forces, and modernizing the Coast Guard’s information systems and networks.
