Log data analysis for threat hunting
Log data analysis is a critical component of threat hunting. It involves inspecting and retrieving useful information from log files generated by various systems, applications, and devices. Traditional security methods may miss suspicious patterns or events, but threat hunters can detect them through constant monitoring and analysis of logs. Threat hunters examine log data in search of certain Indicators of Compromise (IOCs). These IOCs could be domain names, IP addresses, file hashes, or other identifiers linked to known security risks. The problem is that not all logs are the same. Depending on the source of the logs you want to gather, you may need to create a tailored Wazuh decoder. In this section, we will review the following:
