The security architecture design in cloud computing involves multiple layers of security measures to ensure the protection of data and resources. The layers of security architecture design are as follows:
Physical layer: This layer deals with the physical security of the data centers where the cloud infrastructure is housed. It involves physical access controls, monitoring, and surveillance to protect the hardware, network infrastructure, and data centers from physical threats.
Network layer: This layer is responsible for securing the cloud network infrastructure, including firewalls, switches, routers, and other network devices. Network security measures like intrusion detection and prevention, encryption, and virtual private networks (VPNs) are implemented at this layer.
Host layer: This layer involves securing the virtual machines and servers that host the cloud services. It includes measures like access control, encryption, patch management, and antivirus software.
Application layer: This layer is responsible for securing the cloud applications and software. Application security measures like input validation, authentication, and authorization are implemented at this layer.
Data layer: This layer is responsible for securing the data stored in the cloud. Data security measures like encryption, access control, and backup and recovery are implemented at this layer.
Identity and access management (IAM) layer: This layer involves securing the cloud resources by managing user identities and access controls. IAM systems are used to authenticate and authorize user access to cloud resources and data.
By implementing security measures at each of these layers, a comprehensive security architecture design can be achieved to protect cloud resources and data from security threats.
