What is the main reason for tuning a building block?
Tuning a building block in IBM QRadar SIEM V7.5 is primarily aimed at reducing the number of false positives. This process involves adjusting the rules and logic within the building block to better differentiate between normal and suspicious activity. Here's the detailed explanation:
False Positives: High numbers of false positives can overwhelm analysts and obscure genuine threats. Tuning helps in refining detection criteria to reduce these false alarms.
Rule Adjustments: Modifying the thresholds, conditions, and filters within the building block rules to ensure they more accurately reflect the environment's typical behavior.
Improved Accuracy: Enhanced precision in detecting true security incidents, thus improving the overall effectiveness of the SIEM solution.
Reference IBM QRadar SIEM administration guides and best practice documents emphasize the importance of tuning to minimize false positives, ensuring more actionable alerts.
