What will you do?

Key responsibilities include:

• Conduct proactive threat hunting using the HMM-4 approach and Mitre ATT&CK framework.
• Develop and refine hypotheses for targeted threat hunts based on threat intelligence, internal data, and analysis of attacker tactics, techniques, and procedures (TTPs).
• Collaborate with internal teams to collect and analyze security event data from various sources, such as logs, alerts, network traffic, and endpoint telemetry.
• Utilize cutting-edge tools and technologies to identify indicators of compromise (IOCs) and anomalies that may indicate potential threats.
• Perform in-depth analysis of identified threats, assess their impact, and recommend appropriate mitigation and response strategies.
• Document investigative objectives and progress throughout threat hunt. Produce detailed reports and provide clear and concise communication on findings, to include root cause analysis and recommendations for remediation and risk mitigation.
