Leveraging DNS Logs for Endpoint Defense

If I had to choose only a single point of focus for cyber visibility and cyber defense, I would, without a doubt, choose the Domain Name System (DNS) protocol. DNS is a basic protocol, but one of the most important of all computer science and network technologies. DNS logs play a pivotal role in fortifying cybersecurity defenses by serving as a critical intelligence source to detect and thwart malicious activities. As the fundamental translator between user-friendly domain names and machine-readable IP addresses, DNS is an indispensable component of internet communication. Analyzing DNS logs provides a granular view of network traffic, enabling the identification of anomalous patterns and suspicious domain resolutions. This invaluable insight allows cybersecurity professionals to uncover signs of malware infections, Command-and-Control (C2) communications, and other nefarious activities. By scrutinizing DNS logs, organizations can proactively...
