What tool helps incident responders detect data exfiltration attempts?

The correct answer highlights the role of Infoblox in detecting data exfiltration attempts within networks. Infoblox provides advanced DNS services, including security features that can monitor for unusual DNS queries that may indicate data leakage or exfiltration. By analyzing DNS traffic, Infoblox can identify anomalies that suggest sensitive data is being sent outside the organization’s network.

This focus on DNS activity is crucial because many data exfiltration methods utilize DNS as a covert channel to transmit stolen data. Therefore, Infoblox's capabilities in monitoring and analyzing DNS traffic make it particularly effective in identifying and mitigating potential data exfiltration.

Other tools mentioned, like Wireshark, primarily function as network protocol analyzers, which can capture and display data packets for analysis but do not specifically focus on detecting exfiltration attempts. Nuix Adaptive Security is geared more towards analyzing and managing data within organizations rather than real-time detection of exfiltration. DataRobot is a machine learning platform that aids in predictive analytics, rather than serving as a direct tool for detecting security incidents like data exfiltration.
