VectraGPT Introduction
VectraGPT is designed as a specialized AI-driven assistant for analyzing and addressing alerts from Vectra systems and related security incidents, specifically those involving Packet Capture (PCAP) files. With a focus on network security, it integrates seamlessly with Endpoint Detection and Response (EDR) systems, such as Microsoft Sentinel, to provide a comprehensive analysis of network threats. VectraGPT's core purpose is to assist users in identifying, investigating, and resolving security alerts and incidents, enhancing the security posture of organizations. Through its capabilities, VectraGPT offers tailored advice based on the nature of the alert, correlating incidents with MITRE ATT&CK Technique IDs, analyzing PCAP files for malicious activities, and recommending remediation actions grounded in cybersecurity best practices. Its functionality extends to providing detailed steps for further investigation and resolution of Vectra alerts and incidents, making it an essential tool for cybersecurity professionals. Powered by ChatGPT-4o。
Main Functions of VectraGPT
Analysis of Vectra Alerts
Example
Upon receiving a Vectra alert indicating a potential command and control (C&C) activity, VectraGPT analyzes the alert details and the associated network traffic to identify the specific nature of the threat, such as external remote access or hidden tunnels.
Scenario
A cybersecurity analyst receives a high-severity alert from Vectra indicating suspicious C&C behavior. Using VectraGPT, the analyst is able to quickly identify the alert as related to hidden HTTPS tunneling, correlating it to MITRE ATT&CK techniques T1071 (Application Layer Protocol) and T1572 (Protocol Tunneling), and receives guidance on investigating the alert further.
PCAP File Analysis
Example
VectraGPT examines PCAP files to detect anomalies or signs of malicious activities, such as malware communication or data exfiltration attempts, offering insights into the methods and protocols used by attackers.
Scenario
In the case of a suspicious file transfer detected by Vectra, a security professional uses VectraGPT to analyze the corresponding PCAP file. VectraGPT identifies the transfer as a data exfiltration attempt using a hidden HTTP tunnel, provides a detailed breakdown of the malicious traffic, and suggests steps for containment and further analysis.
Integration with EDR Systems
Example
VectraGPT provides recommendations for leveraging integrated EDR systems, like Microsoft Sentinel, to correlate Vectra alerts with endpoint data, enabling a more comprehensive understanding of an incident's impact and scope.
Scenario
Following a Vectra alert about lateral movement within the network, a user employs VectraGPT to integrate findings with Microsoft Sentinel. VectraGPT guides the user in correlating network and endpoint data to identify affected systems and user accounts, facilitating a targeted response to the incident.
