Underseas cables are the lifeline for the global Internet economy and depend on legal protection

Submarine cables and pipelines are vulnerable assets in the global commons.¹⁸² Their protection from undersea attack is a real prescriptive and enforcement challenge because of our extreme reliance on this critical infrastructure; its multi-jurisdictional span beyond territorial seas; the availability of precise locational coordinates; the opaque environment below the waterline; and the accessibility to commercial-grade vehicles that can exploit this environment and inflict disproportionate harm.

The opaque environment and the accessibility to UUVs set this challenge apart from challenges above the water's surface to flagged vessels and platforms. As with cyber threats, this necessitates an effective deterrence policy to compensate for an inability to pinpoint suspected culprits. Not only do legal shortcomings in jurisdiction and security enforcement float above the surface, but arguably more sinister shortcomings lurk below. These threats also require an even more delicate balance between disclosure and secrecy, and between freedom ofnavigation and reasonable restraints for collective security.

In the end, whatever vigor is applied towards cyber security, and whatever balance is struck for internet freedoms should be matched by securing the very cables that transport this life-blood of commerce. Likewise, investment in energy independence should correspond to the security of the very arteries that enable and spur offshore energy exploration.
