In an effort to boost the resiliency of vessels and facilities, the U.S. Coast Guard is urging owners and operators of these structures to fortify their cyber defenses.
The U.S. Coast Guard’s July 8 marine safety alert comes with cybersecurity best practices for vessels. Among them: segment networks into “subnetworks” to make it more challenging for an attacker to gain access; create network profiles for all employees; and be careful of external media, including USB drives.
