Our step-by-step guide to evaluating runtime security tools

Selecting the right runtime security tools is essential for safeguarding cloud-native environments, as traditional cloud audit logs fall short in providing detailed threat detection and incident response capabilities. A comprehensive evaluation using real-world attack simulations on Kubernetes clusters and Linux servers revealed that runtime security tools address these limitations by offering continuous, real-time monitoring of command executions, system calls, and network events, which enhances threat detection and incident response. The evaluation process involved developing attack scenarios, setting up infrastructure, executing attacks, and analyzing results to assess detection capabilities, log richness, and other key factors. It demonstrated that while runtime security tools are vital, they must be complemented with other logging methods, such as Kubernetes audit logs, to ensure a complete forensic analysis. The exercise not only identified gaps in detection and led to improvements in the security tool evaluated but also underscored the importance of scalable, persistent logging infrastructure to prevent loss of critical information post-attack.
