What is the focus of an Interconnection Security Agreement?

• A. Responsibilities.
• B. How interconnected systems will be secured.
• C. Procurement terms.
• D. Financial penalties.

Answer: (B)

An Interconnection Security Agreement centers on the security measures for linking two or more information systems. It lays out how the interconnected systems will be secured, specifying the security controls at the boundary, how data is protected in transit, authentication and access requirements, incident response coordination, and the distribution of responsibilities between parties. This focus on the security safeguards across the connection is what makes it the best answer, as procurement terms, penalties, or broad responsibilities belong to other kinds of agreements and contracts rather than the security-specific interconnection plan.
