A Guide to Hybrid Cloud Security

Enterprise Security Magazine | Tuesday, September 13, 2022

A cloud security posture management (CSPM) solution focuses on detecting misconfigurations and possible risks while guaranteeing compliance across many cloud providers such as AWS, Azure, and Google Cloud.

Fremont, CA: Hybrid cloud security is data and infrastructure protection that incorporates private cloud, public cloud, and on-premises infrastructure components into a cohesive architecture. A hybrid cloud is an IT environment that combines these components. The hybrid cloud provides a high level of flexibility in swiftly transferring workloads to multiple environments while using the better capabilities available in those environments.

There are compelling reasons to employ a hybrid cloud architecture, but it also introduces new security issues, which will get covered in this paper. Let us begin with hybrid cloud use cases.

Components and Controls for Unified Infrastructure

Three components are required to create a unified infrastructure that works in harmony: networking, encryption, and authentication.

• Networking

A hybrid cloud arrangement is created by connecting several cloud infrastructures. Direct network connections between on-premises and clouds, as well as VPN tunnels, are the most prevalent methods and are typically used in tandem, with the direct connection serving as the primary way and the VPN serving as a backup.

• Encryption

Encryption allows users to encode data so only authorized people can access it. When multiple infrastructures and cloud services are interconnected, it's simple to employ an external solution for safe and encrypted communication, which may also get provided by one of the cloud providers in your hybrid cloud landscape.

• Authentication

A hybrid cloud infrastructure allows programs to use services from various cloud providers. For example, suppose the workload on cloud A (or on-premises) has to authenticate to cloud B utilizing a set of credentials.

One must handle those credentials properly, especially in terms of how they're transmitted, because disclosing such credentials might have disastrous implications. Users should also rotate them on a daily basis. As a result, there is an urgent need for hybrid cloud security architecture to connect applications running on the disparate infrastructure.

Cloud discovery and visibility are necessary to manage, configure, and monitor these components in a distributed environment.
