A: The challenge of finding the few meaningful security events amidst millions of benign operational logs.

A: By understanding what 'normal' looks like, the SOC can filter out standard traffic and only alert on deviations.

A: It aids in troubleshooting and operational analytics, making the SIEM valuable to IT operations and increasing their buy-in.

A: It combines multiple low-fidelity events (e.g., login fail + huge data transfer) into a single high-fidelity alert.

A: It is the only scalable way to parse and filter the massive influx of data; manual review is mathematically impossible.

A: Raw logs often lack context; enrichment adds the 'who, what, where' that allows an analyst to make a quick decision.

A: They should be investigated to determine if they are malicious or benign, and then added to the known baseline or alert logic.

A: Historical analysis looks back at stored logs to find long-term patterns (low and slow attacks) that don't trigger real-time thresholds.

A: Regulations like PCI and SOX often mandate log retention and review, providing the budget justification for the system.

A: By mapping them to business risk and asset criticality, ensuring the most dangerous threats to the most important assets are seen first.
