How do you reduce scan noise to avoid tripping rate limits and IDS while still learning enough?

Problem Statement

Explanation

Use smaller port sets and slower timing. Prefer host discovery first, then targeted version checks. Use safe NSE categories. Throttle concurrency. Split scans by subnet and time. Correlate with passive data to skip low-value hosts.
