What condition requires increased monitoring of network activities due to a higher risk of attack?

The correct answer is associated with INFOCON 2, which indicates a heightened state of readiness and reflects an increased potential for a cyber attack. Under INFOCON 2, organizations are advised to intensify monitoring activities across their networks to detect any suspicious behaviors or anomalies that could indicate an impending attack. This is crucial for implementing proactive measures to safeguard systems and data.

INFOCON 3 represents a more routine posture where surveillance is maintained but not at the elevated level necessary to counteract a credible threat. Conversely, INFOCON 4 and INFOCON 5 are conditions that indicate lower levels of threat, where the emphasis may shift towards routine operations and less intense monitoring than that required during heightened threat scenarios. Therefore, the increased vigilance and monitoring required at INFOCON 2 demonstrate a clear and immediate need to protect network assets from potential intrusions or compromises.
