Serverless architecture shifts more responsibility for the underlying infrastructure to the cloud provider. The customer generally focuses on securing application code, permissions, data, and configurations, while the provider handles host maintenance, infrastructure management, and much of the system patching.

Secure Real-Time Transport Protocol (SRTP) is a security protocol used to encrypt and authenticate the streaming of audio and video over IP networks. It ensures that the video streams from the IP cameras are both encrypted to prevent unauthorized access and authenticated to verify the integrity of the stream, making it the ideal choice for securing video surveillance.

Sanitization is the process of removing sensitive data from a storage device in a manner that ensures the data cannot be recovered while allowing device to be reused. This involves methods like overwriting the data with zeros or other patterns multiple times.

Rescanning the server after applying a security patch confirms whether the vulnerability has been successfully remediated and is no longer detected.
