What is hybrid cloud security architecture?

Hybrid cloud security begins at the hardware level, located on-premises. Here, servers and bare-metal hardware contain all enterprise data, from code to databases to storage and other resources. And since this information is made available through one or several data centers and cloud environments, it is encrypted so only valid users and applications access and use it, typically through some form of zero-trust protocol.

On the perimeter, edge cloud servers and application containers undergo microsegmentation, meaning data is divided into groups and specific workloads, effectively isolating them with specific security controls. These “demilitarized zones” limit a cyberthreat’s ability to move through a data center. Firewalls add additional layers of protection, further separating cloud environments from on-premises resources, and can be implemented at several layers, including the hypervisor and operating system.

What are the components of hybrid cloud security?

To safeguard data, apps, and infrastructure in private and public clouds, hybrid cloud security includes many critical components. These components include:

  • Identity and access management (IAM): Implementing strong IAM rules and controls to authenticate users and manage resource access independent of location or cloud environment.
  • Data encryption: Encryption methods protect data while it's being sent and stored, keeping private data safe from unauthorized interception.
  • Network security: Using firewalls, intrusion detection/prevention systems, and VPNs to safeguard on-premises and cloud communications.
  • Compliance and governance: Creating policies and processes to comply with legislation, industry standards, and governance frameworks to enforce security controls and best practices.
  • Security monitoring and incident response: Detecting and responding to security risks quickly to minimize the effect of breaches or security events.

Hybrid cloud security strategy combines components to safeguard data and applications in a hybrid environment.
