Which tool helps incident responders perform log analysis during a web application security incident?

The correct choice for a tool that aids incident responders in performing log analysis during a web application security incident is known for its capabilities in application performance monitoring and error tracking. It collects and analyzes logs from applications, which can be invaluable when investigating security incidents, as it provides insights into application behavior, performance issues, and potential security threats. This tool’s features allow responders to get a comprehensive view of the application’s health and identify any anomalies that could indicate an attack or vulnerability being exploited.

In contrast, the other tools listed serve different purposes. Proxy Switcher is primarily used for managing and switching between multiple proxy settings, which does not directly assist in log analysis for security incidents. Atomic OSSEC is a host-based intrusion detection system (HIDS) that focuses more on intrusion detection rather than detailed log analysis specifically during web application incidents. ClamAV is an antivirus tool designed for detecting malware and does not focus on log analysis from web application events.

Thus, the choice related to application performance and log aggregation aligns best with the needs of incident responders focused on web application security incidents.
