FireEye detects and prevents zero-day attacks by addressing all stages of an attack lifecycle with a signature-less engine utilizing stateful attack analysis. Here’s a step-by-step breakdown of how this works:

1. Signature-less Detection: Unlike traditional antivirus solutions that rely on known signatures of malware, FireEye uses a signature-less approach. This means it doesn't need prior knowledge of the specific malware to detect it.

2. Stateful Attack Analysis: FireEye employs stateful attack analysis, which means it monitors and analyzes the state and behavior of network traffic and system activities over time. This helps in identifying suspicious patterns that could indicate an attack.

3. Lifecycle Coverage: FireEye's technology is designed to address all stages of an attack lifecycle, from initial infiltration to lateral movement within the network, and finally to data exfiltration or other malicious actions. By covering the entire lifecycle, it can detect and mitigate attacks at various stages.

4. Behavioral Analysis: The system looks for abnormal behaviors and activities that deviate from the norm. This includes unusual file modifications, unexpected network connections, and other indicators of compromise.

5. Real-time Protection: FireEye provides real-time protection by continuously monitoring and analyzing network traffic and system activities. This allows it to detect and respond to threats as they occur, rather than after the fact.

6. Advanced Threat Intelligence: FireEye leverages threat intelligence gathered from a global network of sensors and research teams. This intelligence helps in identifying new and emerging threats quickly.

By combining these advanced techniques, FireEye can effectively detect and prevent zero-day attacks, which are attacks that exploit previously unknown vulnerabilities.
