Spotting the Difference: Targeted Intrusion vs Automated Scan

A recent SANS diary entry detailed a week‑long investigation where security analysts initially flagged dozens of inbound connection attempts as possible breaches. By correlating source IP reputation, timing, payload consistency, and the presence of known threat‑actor tooling, the team identified a small subset of events that matched a sophisticated, purpose‑built intrusion campaign, while the majority were low‑effort, automated scans probing for exposed services.

Understanding these contextual clues cuts down false‑positive workload, shortens response times, and prevents attackers from slipping through unnoticed. Defenders who can quickly separate noisy background traffic from genuine, targeted activity can allocate resources to contain real threats, improve threat‑intel enrichment, and strengthen overall detection hygiene.
