What is Amazon GuardDuty?
Amazon GuardDuty is a continuous security monitoring platform that analyzes and processes VPC flow logs, AWS CloudTrail event logs and DNS logs. It uses threat intelligence feeds, such as lists of malicious IPs and domains to identify malicious activity within your AWS environment.
You can enable the GuardDuty Service through your Amazon Console. Once there, you are then presented with the GuardDuty dashboard, as shown in the example below:
Finding are rated as High, Medium or Low on the dashboard and have the following meaning:
High findings indicates that the resource in question is compromised and is actively being used for unauthorized purposes.
Medium findings indicates suspicious activity, for example, a large amount of traffic being returned to a remote host that is hiding behind the Tor network.
Low findings indicates suspicious or malicious activity that was blocked before it compromised your resource.
Integrating CloudHunter with GuardDuty
CloudHunter integrates with Amazon GuardDuty to enable customers to comprehensively manage risk across AWS and other leading cloud services such as Microsoft Azure. CloudHunter ingests Amazon GuardDuty findings and provides a centralized view on security risks, leading to more actionable alerts and incidents, and faster, automated remediation.
Key benefits of integrating Amazon GuardDuty with Sift Security CloudHunter include:
- Centralized & Enhanced Cloud Visibility: CloudHunter correlates GuardDuty findings with finding from other cloud security products such as Amazon Inspector, as well as raw cloud data such as CloudTrail and VPC Flow, and related logs such as host logs. Sift Security provides comprehensive visibility to all of this data including alerts, dashboards, search, and our innovative graph canvas visualization and investigative interface.
- Enhanced Alerts: CloudHunter pulls in findings from products like Amazon GuardDuty and Inspector, and enriches those alerts by correlating them with other risks and relevant context. For example, if we see an alert related to an instance, the score of the alert is affected by its context: (a) are there any vulnerabilities? (b) is the instance in a sensitive account? (c) does the instance have excessive permission? This context combined with our clustering algorithms enables the highest fidelity, most actionable alerts to be surfaced as possible incidents which should be investigated immediately.
- Entity Behavioral Analysis: CloudHunter identifies the riskies entities, including accounts, users, instances, and storage. These entity views are generated by combining alerts from multiple sources, anomalous activity, and business context. Analysts can easily investigate the riskiest entities by filtering all alerts associated with that entity and exploring the alerts in the graph canvas.
- Easier, Faster Investigations: Through the correlation and enrichment above, analysts start with a small number of actionable alerts, and have all the necessary context to rapidly investigate root cause and impact. These investigations include filterable alert tables, alert details, search, and graph canvas, which allows simple investigations that do not require in depth understanding of the underlying data structure and allow for seamless pivoting across entities and IOCs.
- Seamless, Automated Response: Sift Security offers a number of integrations out of the box, that allow users to take seamless manual action or create automated play-books. Additionally, our customers can easily add additional integrations to meet their needs.
