Unlock Advanced Network Hunting with Zeek: Enhance your Hunting Experience with Layer Signals

Enrich Your Advanced Hunting Experience Using Network Layer Signals from Zeek
Introduction to Zeek Network Layer Signals
Zeek is an open source network security monitoring (NSM) and network traffic analysis (NTA) tool used by cybersecurity experts to detect malicious activity. Zeek collects logs and network layer information, such as TCP/IP traffic and DNS queries, which can be used to detect and investigate malicious activity. This information can be used to enrich advanced hunting in Microsoft Defender for Endpoint.

How Does Zeek Collect Network Layer Signals?
Zeek collects network layer signals from the network it is monitoring. It does this by passively listening to the network traffic and logging the events it detects. Zeek uses a custom parsing language, called Bro, to parse the information it collects. It is then able to create logs of the events detected, such as TCP/IP connections, DNS queries, and HTTP requests, as well as other network-related information.

How Can Zeek Network Layer Signals Help with Advanced Hunting?
Zeek network layer signals can be used to enrich advanced hunting in Microsoft Defender for Endpoint. With Zeek, security analysts can quickly identify suspicious activity and investigate further. Zeek can be used to detect various types of malicious activity, such as command and control (C2) communication, lateral movement, and data exfiltration. Zeek can also be used to detect anomalous behavior, such as unexpected ports or services being used.

Conclusion
Zeek is a powerful tool for network security monitoring and network traffic analysis. It can be used to enrich advanced hunting in Microsoft Defender for Endpoint, allowing security analysts to quickly identify suspicious activity and investigate further. With Zeek, security analysts can detect various types of malicious activity and anomalous behavior, helping to keep their organization safe from threats.
