Which of the following refers to improving data integrity by removing IPS events?

Data normalization is a process that enhances data integrity by ensuring that information is organized in a way that reduces redundancy and improves consistency within a database or dataset. In the context of security, this often involves filtering out or consolidating events from Intrusion Prevention Systems (IPS) to eliminate false positives and irrelevant data. By normalizing data, analysts can focus on the most pertinent incidents, thus improving their ability to identify genuine threats and ensuring that the data they analyze is accurate and reliable.

This process plays a crucial role in cybersecurity operations. It allows security professionals to more effectively correlate events and alerts, leading to faster and more accurate incident response. When data are consistently formatted and cleaned, it enhances the quality of analyses conducted on it, ultimately contributing to a more robust security posture.

On the other hand, the other options have different purposes. Digital signing pertains to authenticating data to confirm its origin and integrity, operational cleaning typically refers to broader organization processes rather than just data integrity, and integrity validation involves checking the reliability and correctness of data rather than actively improving it through the removal of unnecessary events.
