- Dynamic Application Security Testing (DAST)
- Open-source and dependency vulnerability scanning
- Tune tools and rules to balance coverage, accuracy, and developer experience.
- Ensure security testing is integrated early in the pipeline to enable remediation prior to final build and deployment.
Vulnerability Management & Remediation- Partner with engineering and application teams to ensure findings from SAST, DAST, and open-source scans are incorporated into the Risk Operation function and:
- Clearly triaged and prioritized
- Assigned appropriate ownership
- Remediated within agreed SLAs and timelines
- Track remediation progress and escalate systemic or repeated issues.
- Validate remediation and support secure release decisions.
Collaboration & Enablement- Act as a trusted security partner to development and other relevant teams.
- Provide guidance on secure coding practices, vulnerability remediation, and threat patterns.
- Support application security reviews, threat modeling, and design discussions as needed.
- Contribute to continuous improvement of application security tooling, processes, and metrics.
