• Detection and Threat Hunting Handoffs: Partner with Security Detections, Threat Intelligence, and Threat Hunting teams to ensure ASM findings inform detection engineering, hunt development, and intelligence-driven security priorities.
• Program Maturity: Develop and maintain repeatable processes, SOPs, playbooks, reporting standards, and quality expectations for ASM workflows. Identify opportunities to improve consistency, scalability, and operational maturity across the function.
• Incident Response Support: Support the incident response team by providing insight into potential attack paths, exploitable vulnerabilities, exposed assets, and adversary techniques that may be relevant during a cyber incident.
• Written Documentation: Create, review, and update documentation related to attack surface management processes, findings, reports, remediation recommendations, playbooks, and security controls.
• Communication: Provide clear and concise written and verbal communication, including technical reporting, long-form documentation, stakeholder updates, and executive presentations. Translate technical detail into language appropriate for the intended audience.
