Automated Incident Investigation Together, HPE ArcSight ESM, and Hexadite AIRS provide near real-time investigation of security alerts to help close the gap between detection and response. Hexadite leverages the ArcSight Data Platform to collect, query, and investigate additional contextual information to help determine if an alert is a true positive or if it can be closed without the need for manual review. Through automation, false positives can be ruled out more quickly, and large scale events that combine multiple alerts can be managed more efficiently. Efficiencies result in the need for fewer security analysts, and experienced analysts can spend more time on validated alerts.
Remediation Hexadite AIRS analyzes security events and can perform targeted mitigation actions to take place such as closing a connection, killing a process, quarantining a file, changing a firewall rule, etc. In semi-automated mode, once Hexadite AIRS validates a threat and determines the best course of mitigation action, Hexadite AIRS sends a notification to HPE ArcSight ESM, bringing the event to the attention of an analyst who reviews the information and makes a call back to Hexadite AIRS to approve the remediation execution. Once a team is comfortable with the remediation recommendations, the solution can be deployed in fully automatic mode performing the full investigation and remediation automatically.
Reporting The proliferation of security tools deployed throughout an organization’s environment makes it important that there be one place for all security information. Once an event is analyzed and any necessary remediation is completed, Hexadite sends back its analysis and closes the loop with HPE ArcSight. Case and alert management in HPE ArcSight provide users with a complete history of alerts, analysis, and status until closure. With the insights from Hexadite, HPE ArcSight correlation rules can be fine-tuned to continuously reduce false positives resulting in ongoing improvements.
