To ensure that sensitive data, such as Personally Identifiable Information (PII), is not modified, the bank should implement file integrity monitoring (FIM). FIM tracks changes to files and provides alerts if unauthorized modifications are detected, ensuring data integrity.
* Full disk encryption protects data at rest but does not prevent or monitor modifications.
* Network access control (NAC) manages access to the network but doesn't monitor file changes.
* User behavior analytics (UBA) detects suspicious user activities but is not focused on file integrity.

A tabletop exercise is the most effective way to quickly assess a cybersecurity team's readiness to respond to a threat scenario. CompTIA Security+ SY0-701 describes tabletop exercises as discussion-based simulations where incident response team members walk through a realistic scenario to evaluate procedures, decision- making, communication, and coordination. These exercises are specifically designed to be conducted in a short timeframe while still providing meaningful insight into preparedness.
Executing a tabletop exercise allows management to observe how the team identifies threats, escalates incidents, assigns roles, and follows the incident response plan. Documenting performance results helps formalize findings, identify gaps, and improve playbooks and procedures without the complexity of a live incident or full-scale simulation.
Option A is informal and does not test real-time decision-making. Option B focuses on vulnerability discovery, not response readiness. Option D can be effective but is time-consuming and not suited for rapid assessment.
Therefore, C: Execute a tabletop exercise and document the performance results is the correct answer.

Detailed Explanation:
Daily vulnerability scans help identify missing patches or updates across endpoints, allowing security teams to ensure compliance with patch management policies. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Vulnerability Management".

Detailed Explanation:
Baseline enforcement ensures that all systems adhere to predefined security configurations, such as approved OS versions and patch levels, improving compliance and reducing vulnerabilities.
