I advocate for a 'shift-left' approach, embedding security practices early in the SDLC. This includes threat modeling during design, static and dynamic code analysis during development, and security testing in QA. By integrating security checks at each phase, vulnerabilities are identified and mitigated sooner, reducing risks and costs. Collaboration with development teams ensures security is a shared responsibility, fostering a culture of security awareness and proactive risk management.

I regularly follow industry resources like OWASP, SANS, and security blogs, and participate in webinars and conferences. Subscribing to threat intelligence feeds and engaging with the security community helps me stay informed about emerging threats. I also conduct regular training sessions and workshops to share knowledge with my team, ensuring we collectively stay ahead of evolving risks and adopt best practices.

In a previous role, I identified a critical SQL injection vulnerability during a code review. I immediately collaborated with the development team to patch the issue and implemented input validation and parameterized queries to prevent recurrence. Additionally, I conducted a thorough review of the codebase to identify similar vulnerabilities and provided training to developers to enhance their secure coding practices, ensuring long-term resilience.

I align security goals with business priorities by understanding the organization's risk appetite and operational needs. I prioritize risks based on their potential impact and likelihood, ensuring critical vulnerabilities are addressed first. By communicating the business value of security measures and proposing cost-effective solutions, I ensure security enhances, rather than hinders, business objectives while maintaining a robust security posture.

I use a combination of tools like SAST (e.g., SonarQube), DAST (e.g., OWASP ZAP), and SCA (e.g., Dependency-Check) to identify vulnerabilities. Manual penetration testing complements automated tools to uncover complex issues. I also employ threat modeling and risk assessment methodologies to prioritize vulnerabilities and ensure comprehensive coverage, aligning testing efforts with the application's risk profile and business context.
