• Evaluate and support the integration of telecom-specific security tools and technologies (e.g., firewalls, IDS/IPS, signaling protection), ensuring alignment with network architecture standards.
• Perform telecom-focused risk assessments and support penetration testing of RAN, Core, and Transport domains, providing findings and recommendations to the central Information Security team.
• Collaborate with network engineering teams to secure SDN/NFV-based transport networks, ensuring compliance with Zero Trust security models and cloud-native security practices.
• Contribute to incident response activities by supporting containment and remediation within the telecom infrastructure, in coordination with the primary Information Security Incident Response team.
• Guide the selection and implementation of AI-driven telecom-specific security automation tools, enhancing ADC’s ability to detect and respond to emerging network security threats in real time.
• Define and document network security requirements, technical guidelines, and configuration baselines for the 4G/5G telecom network infrastructure, ensuring they align with broader security governance frameworks and with best practices.
• Provide domain-specific reporting on telecom infrastructure risks and compliance status, feeding into organization-wide cybersecurity dashboards and executive reviews.
