C. average score
D. least severe score
Answer
A. most severe score
Explanation
In Palo Alto Networks’ Cortex XSOAR (formerly Demisto), DBot is an AI-powered chatbot that assists security analysts in various tasks, including threat intelligence analysis. When dealing with indicators that have multiple reputation scores from different sources, DBot employs a conservative approach to ensure the highest level of security.
Here’s a detailed explanation of why DBot uses the most severe score:
- Risk mitigation: By choosing the most severe score, DBot ensures that potential threats are not underestimated. This approach aligns with the principle of erring on the side of caution in cybersecurity.
- Comprehensive threat assessment: Different reputation services may have varying levels of visibility or different scoring criteria. By considering the most severe score, DBot takes into account the worst-case scenario presented by any of the reputation sources.
- Alerting priority: Using the most severe score helps prioritize indicators that require immediate attention. This allows security teams to focus on potentially high-risk threats first.
- False positive reduction: While this method might seem to increase false positives, it actually helps reduce the risk of false negatives, which can be more dangerous in a security context.
- Consistency in threat intelligence: This approach provides a consistent method for handling conflicting reputation data, ensuring that analysts can rely on a standardized evaluation process.
- Integration with other security tools: The most severe score approach aligns well with other security tools and practices that often prioritize addressing the highest-risk threats first.
It’s important to note that while DBot uses the most severe score for initial assessment, security analysts can still view all the individual scores from different sources. This allows for a more nuanced analysis when needed, considering factors such as the reliability of each source and the context of the indicator.
Understanding this scoring mechanism is crucial for security professionals working with Cortex XSOAR, as it impacts how threats are prioritized and addressed within the platform. This knowledge is particularly relevant for those preparing for the Palo Alto Networks PSE-Cortex certification exam, as it demonstrates an understanding of how Cortex XSOAR’s AI-driven components operate in threat analysis scenarios.
