Secure Sockets Layer (SSL) is a technology that encrypts data sent between a user's browser and a website or application on a server. The purpose of SSL is to secure the information preventing eavesdropping and tampering. Originally released in 1995, SSLv2 is a protocol used to encrypt data sent over the internet, ensuring that the information remains private and secure.

As businesses continue to embrace the flexibility and scalability of cloud-native applications managed by Azure Kubernetes Service (AKS), ensuring robust data protection for them across diverse locations, including edge environments, becomes paramount. For organizations leveraging Kubernetes at the edge with Azure Arc, the need for a comprehensive and easily managed backup and disaster recovery solution is crucial.

Admission control is a crucial part of the Kubernetes security, enabling the approval or modification of API objects as they are submitted to the server. It allows administrators to enforce business logic or policies on what objects can be admitted into a cluster. Kubernetes RBAC is a scalable authorization mechanism, but lacks the fine grained control over different Kubernetes objects. This creates the need for another layer of control which is Admission Policies.

Application security is the combination of tools, practices, and policies that are used to protect the application layer of software from threat actors. Once something of an afterthought, application security is now widely and rightfully recognized as a vital part of the software development life cycle (SDLC). As the complexity of technology increases, considering application security early and often in the SDLC is imperative to keeping data and resources from falling into the wrong hands.
