11. Can you explain the process of creating and managing ArcSight ESM dashboards?

Ans: In ArcSight ESM, dashboards provide visual representations of security events and metrics. To create and manage dashboards, you would define widgets with specific queries or visualizations, arrange them on the dashboard layout, and set access permissions for different users or user groups. Dashboards can be customized to display real-time or historical data as required.

12. How would you configure and manage event correlation rules in ArcSight ESM?

Ans: Event correlation rules in ArcSight ESM help identify patterns and relationships between different security events. To configure and manage these rules, you would define correlation conditions, specify the sequence of events, set thresholds, and assign appropriate actions. Regular review and fine-tuning of correlation rules based on feedback and observed events are important for effective detection and response.

13. How do you perform incident handling and response using ArcSight ESM?

Ans: ArcSight ESM provides tools and workflows to manage security incidents. When an event triggers an alarm or matches a specific correlation rule, ArcSight ESM can automatically generate alerts and initiate incident response processes. Incident handling involves investigating and analyzing events, gathering additional evidence, coordinating with relevant teams, and taking appropriate remedial actions to mitigate the threat.

14. What are the best practices for ArcSight ESM performance optimization and tuning?

Ans: Some best practices for performance optimization in ArcSight ESM include:

Regularly monitoring system performance metrics. Scaling hardware resources based on workload and data volume. Optimizing correlation rules to reduce false positives and negatives. Maintaining an appropriate log retention policy to manage storage requirements. Regularly applying software patches and updates provided by the vendor. Conducting periodic system health checks and audits.

15. How would you troubleshoot and resolve issues related to ArcSight ESM?

Ans: When troubleshooting ArcSight ESM issues, you would follow these steps:
