A cybersecurity team is investigating a complex cyber threat landscape for a large financial institution. The team is aware of some potential threats due to previous encounters and security measures in place, but the evolving nature of the landscape presents new threats and challenges. What type of cyber environment is the team dealing with?
A. Fully known environment
B. Reconnaissance
C. Unknown environment
D. Partially known environment

The cybersecurity team is dealing with a Partially known environment. Due to the constantly evolving nature of cyber threats, they face new challenges alongside known ones which they aim to manage through continuous surveillance and upgrades. The correct option is D

Explanation:

The cybersecurity team at a large financial institution is dealing with a Partially known environment. This means that while they have knowledge of some threats from past encounters and have implemented security measures, the evolving nature of threats presents new challenges that are not yet fully understood. Because cybersecurity landscapes evolve and new vulnerabilities, such as zero-day attacks, can emerge at any time, no system can be considered 100% secure. With attacks becoming more common and sophisticated, continuous surveillance, system upgrades, employee education, and regulatory advancements are crucial in protecting against potential cyber threats.
