The NIST SP 800-47 document defines an interconnection as the direct connection between two or more IT systems or networks that enables the exchange of data. The document also describes the interconnection life cycle, which includes several phases that organizations must follow to ensure that the interconnection is established and maintained securely.
The answer to the question is A. Establishing the interconnection. This phase is where organizations build and execute a plan for establishing the interconnection, including executing or configuring appropriate security controls.
During this phase, the organizations involved in the interconnection develop a plan that includes the technical and administrative aspects of the interconnection. This includes defining the technical requirements for the interconnection, establishing security controls and procedures, and identifying the roles and responsibilities of each organization involved.
The plan must also include the necessary security controls and configurations to ensure the confidentiality, integrity, and availability of the information being exchanged over the interconnection. These controls may include firewalls, intrusion detection and prevention systems, access control mechanisms, and encryption.
Once the plan is developed and approved, the organizations execute it by establishing the interconnection and configuring the security controls. This may involve setting up virtual private network ( VPN) connections, configuring firewalls, and implementing access controls.
Finally, the organizations must test the interconnection and the security controls to ensure that they are functioning correctly and effectively. Any issues or vulnerabilities that are discovered during this testing must be addressed before the interconnection is considered operational.
In summary, the establishing the interconnection phase of the interconnection life cycle is where organizations build and execute a plan for establishing the interconnection, including executing or configuring appropriate security controls.
