Final answer:
CPCON 2 is the condition where the priority focus is on critical and essential functions in response to increased cyber threat or ongoing cyber attacks, requiring additional security measures to protect vital systems.
Step-by-step explanation:
Under the Cyberspace Protection Condition (CPCON) system, CPCON 2 is the condition where the priority focus is limited to critical and essential functions. This escalated level of protection implies that there is an increased risk of cyber threat or that some form of cyber attack is occurring, so only the most important activities are maintained to ensure security and operational integrity of critical systems.
CPCON levels are part of a military or defense framework designed to provide standardized measures for the protection and defense of information systems and networks. At CPCON 2, organizations may need to implement additional security measures such as stricter access controls, increased monitoring of network traffic and information systems, and additional cybersecurity training for personnel.
