Phase 3 - Zero-Day Threats, Known Vulnerabilities and Anomaly Detection
What are the most common mechanisms used in the "Exploit" phase? Many attacks simply take advantage of known vulnerabilities or network weaknesses that have not been addressed, in which case the adversaries have no need to create custom malware. When they are employed, "zero-day" attacks are often very difficult to detect as they exploit hidden or as yet unknown vulnerabilities in applications, operating system features or user accounts, making them difficult to detect. But as these weapons are installed, become resident and establish command-and-control communications, they do create a trail of threat indicators that can be detected, followed and acted upon. This session will discuss some of the known vulnerabilities that are still most commonly exploited, and identify multiple strategies for detecting and responding to zero-day malware, as well as discuss mechanisms such as:
- Behavioral- and signature-based analysis;
- Virtualization, sandboxing and hardware/CPU-based isolation of suspicious programs and traffic;
- Malware and network anomaly detection, correlation and reporting.
