Merck's 10-K describes its cybersecurity program as led by a dedicated CISO group, with the person currently in that seat holding it on an interim basis.

"The Company's interim CISO has over 22 years of experience in cybersecurity and national security, including distinguished service in the U.S. Army and the National Security Agency," the filing states, adding that the interim CISO holds a master's degree in Cyber Intelligence Studies and a bachelor's degree.

The filing describes the CISO's group as responsible for leading enterprise-wide cybersecurity risk management, strategy, policy, standards, architecture and processes, but does not name the interim CISO, say when the interim appointment began, or say whether a permanent CISO search is underway.
