Detective—your AWS security analyst

Amazon Detective serves as a robust analytical engine designed to assist security professionals in dissecting, understanding, and responding to security issues and anomalies. It acts as an extension to other AWS security services such as GuardDuty, offering advanced correlation techniques that go beyond basic alerting. By ingesting and correlating data from a multitude of AWS services, Detective provides a more nuanced and comprehensive view of your security landscape. This is particularly beneficial for complex environments where multiple AWS services are in use and the security signals are often too noisy or too subtle to catch.

Key features

Detective has the following key features:

Data aggregation and correlation: Detective is adept at pulling in data from various AWS services, including GuardDuty, AWS CloudTrail, and VPC flow logs. It then employs advanced algorithms to correlate this data, offering a unified view of security events across your AWS environment.
ML algorithms: The service uses ML to analyze data and identify patterns that could indicate a security incident. This is particularly useful for detecting sophisticated threats that might not trigger traditional security mechanisms.
Graphical visualization: One of the standout features is its ability to provide graphical representations of correlated data. This helps in understanding the relationships between different AWS resources and activities, which is crucial for incident investigation.
Grouping of related findings: A recent addition to Detective is its capability to automatically group related GuardDuty findings that may appear unrelated but can indicate a multi-stage attack when analyzed together.
MITRE ATT&CK framework integration: Detective also maps its findings to the tactics, techniques, and procedures (TTPs) outlined in the MITRE ATT&CK framework, providing a structured approach to threat detection and response.
