Threat hunting is the proactive process of searching for and identifying potential threats within an organization's network. It involves the use of specialized tools and techniques to identify patterns of malicious activity or indicators of compromise (IOCs) that may not be detected by traditional security measures.
Here are some examples of threat hunting activities:
Analyzing network traffic: Threat hunters may examine network traffic logs to identify unusual or suspicious activity, such as traffic from known malware domains or traffic patterns that suggest an attacker is attempting to exfiltrate data.
Searching for IOCs: Threat hunters may use tools such as antivirus software or intrusion detection systems (IDS) to search for known indicators of compromise, such as specific file hashes or IP addresses associated with known malware.
Conducting system audits: Threat hunters may conduct audits of systems and servers to identify vulnerabilities or misconfigurations that could be exploited by attackers.
Analyzing system logs: Threat hunters may review system logs, such as event logs or firewall logs, to identify unusual activity or events that may indicate the presence of a threat.
Correlating data: Threat hunters may analyze data from various sources, such as network traffic logs, system logs, and user activity logs, to identify patterns or correlations that may indicate the presence of a threat.
Overall, the goal of threat hunting is to identify and mitigate potential threats before they can cause harm to an organization. By proactively searching for threats and identifying indicators of compromise, threat hunters can help to prevent data breaches and other security incidents.
