What is Serverless Security in Cybersecurity?
Cloud Security
Version 1.0 · Published April 2026 · Last verified April 2026
Serverless security covers the threats and protections specific to function-as-a-service platforms like AWS Lambda, Azure Functions, and Google Cloud Functions. Key concerns include overpermissioned execution roles, insecure function code, dependency vulnerabilities, and event injection attacks. The shared responsibility model shifts more infrastructure security to the provider, but application-layer risk stays with the customer.
Why Serverless Security Matters for Your Cybersecurity Career
Serverless adoption is growing because it reduces operational overhead. But the security model differs significantly from traditional applications. Security professionals who understand serverless-specific risks can advise development teams on secure function design, least-privilege IAM roles, and proper input validation. This specialization is still relatively rare.
