Proactively Detecting Lateral Movement to Mitigate Cybersecurity Risks

This guide outlines the critical stages of lateral movement in cybersecurity, detailing how attackers exploit networks after gaining initial access. It describes the reconnaissance phase, where adversaries gather intelligence about their targets, followed by credential theft and privilege escalation, which enable them to move laterally within the network. The guide presents various techniques attackers use to remain undetected, such as internal spear phishing and exploiting remote services. It also discusses the limitations of current solutions in detecting lateral movement, including insufficient network visibility and inadequate detection of stealthy techniques. Furthermore, it lists indicators of lateral movement that organizations should monitor, such as suspicious network connections and abnormal access patterns. Finally, the guide suggests strategies for detecting lateral movement, including implementing security information and event management (SIEM) systems, endpoint detection and response (EDR), and user entity and behavior analytics (UEBA) capabilities to enhance threat detection and response capabilities.
