Passive DNS replication and analysis provide a practical alternative for studying live DNS behavior without requiring full authoritative control. This survey examines state-of-the-art implemented systems using passive DNS for malicious behavior detection, comparing strengths, weaknesses, collected datasets, and detection outcomes. The review highlights shared incremental patterns and widespread supervised machine learning usage, and shows potential near real-time gains using big-data analytics prototypes.","cbCaihshjqnftlIu","https://ap.wps.com/l/cbCaihshjqnftlIu","pdf",5411774,1,27,"English","en","# Introduction\n## DNS as an Attack Vector\n## Challenges of Live DNS Monitoring\n## Passive DNS Analysis and Survey Scope","[{\"question\":\"Why is DNS considered important for both normal operations and attacks?\",\"answer\":\"DNS enables domain-to-IP resolution that supports services like email and web.
