The Risk of Exposed Cloud Functions and How to Harden

Publicly exposed serverless applications are often found to be vulnerable to attacks, which can lead to full control over the underlying container instance. This can serve as a foothold for further attacks on the cloud environment. To mitigate this risk, hardening strategies should be implemented to secure serverless environments. These principles apply universally to any public serverless deployment. Engineers should prioritize securing serverless applications, especially with the growth of generative AI adoption.
