Step-by-Step Data-Driven Hunting Workflow

"Machine learning models show anomalous outbound data spikes on web ports." Step 2: Data Collection and Normalization Which make up the majority of your enterprise infrastructure

The you currently collect (e.g., Sysmon, Defender for Endpoint, CrowdStrike)

You cannot hunt for what you do not log. Ensure your Security Information and Event Management (SIEM) or Extended Detection and Response (XDR) platform collects the following critical data points: Log Category Key Event IDs / Fields to Watch Windows Security Logs, Sysmon Ensure your Security Information and Event Management (SIEM)

Indicators of Compromise are pieces of forensic data that identify malicious activity. Security teams classify IoCs using David Bianco's , which ranks indicators by how difficult they are for an attacker to alter.

: Leveraging third-party reports (e.g., FireEye, Palo Alto) and open-source feeds to identify Indicators of Compromise (IOCs). Instead of focusing purely on the attacker's tools,

Instead of focusing purely on the attacker's tools, MITRE ATT&CK categorizes an adversary's actions into distinct tactics (e.g., Initial Access, Execution, Privilege Escalation, Lateral Movement, Exfiltration ). By mapping threat intelligence to these specific techniques, threat hunters can build targeted queries designed to hunt for the behaviors an attacker must exhibit to achieve their goals, regardless of the specific malware they are using. Building Your Hunting Environment

The benefits of practical threat intelligence and data-driven threat hunting include:

Many teams collect feeds but never use them. The "Data-Driven" approach changes this:
