- Support deployment and ongoing execution of data encryption controls for sensitive data at rest and in transit, in alignment with enterprise encryption standards and data handling requirements.
- Coordinate encryption enablement activities with platform teams, data owners, and application teams, including validation, testing, and documentation of implemented controls.
- Support data classification and labeling efforts by validating detections, refining patterns/classifiers, and assisting with coverage expansion and quality improvements.
- Conduct basic investigations by correlating alert details with relevant logs/telemetry and partnering with the SOC/IR teams when additional investigative depth is needed.
- Identify when to engage key stakeholders (e.g., Legal, Privacy, Compliance, HR, business owners) and coordinate escalation pathways based on defined criteria.
- Create and maintain operational documentation, including runbooks, response playbooks, encryption validation steps, and standard operating procedures.
- Track and report operational metrics such as alert volumes, false positives, time-to-resolution, and recurring themes requiring control or policy changes.
- Participate in continuous improvement activities, including encryption coverage expansion, policy reviews, rule enhancements, and operational process improvements.
- Work effectively within an analyst team by sharing workload, coordinating priorities, maintaining coverage, and supporting a customer-focused service mindset.
- Promote a culture of accountability, collaboration, and operational excellence while supporting the broader Data Security Program's goals.
