Centralization of Multi-Cloud Security

By Cloud Computing Outlook | Wednesday, May 29, 2019

FREMONT, CA – Centralization has emerged as a primary factor to be considered when adopting a multi-cloud security strategy. It can alleviate the flaws in fragmented security access and monitor controls. Piecemeal solutions can prove challenging for the security teams to execute, especially if the security solution is designed and executed by distinct providers.

Many cloud operation teams seek the assistance of multi-cloud dealers in centralizing the cloud management, whereas, some adopt a single platform to integrate all tools and solutions, thus facilitating centralized control of security policy and access management.

The security teams have to assess the available controls for cloud management before adopting a multi-cloud security strategy. Most of the endpoint security tools such as malware and endpoint detection can work across multiple cloud environments.

The centralization of cloud workload image building may increase its dependency on infrastructure as code definitions than traditional imaging tools. The consistency of the deployed solutions can be achieved through configuration management platforms such as Puppet, Chef, and Ansible.

Since most of the enterprise vulnerability scanners posses integration capabilities with major cloud platforms, there is no need for adopting a fragmented solution. Several cloud scanning and assessment tools such as Redlock, DivyCloud, and CloudCheckr can monitor configurations of cloud accounts and environments.

The major providers of security information and event management (SIEM) and analytics have made it possible to integrate their solutions with the premier cloud providers. It has opened the doors for new security-as-a-service offering, facilitating the integration of the cloud environment to a central source for evaluation. The utilization of infrastructure-as-code tools such as Terraform can facilitate seamless integration with cloud-native template technology such as AWS CloudFormation and Azure Resource Manager Templates.

However, not every tool is easy to integrate. When it comes to encryption, many organizations opt for essential management tools from a specific cloud provider. Also, it will prove challenging to integrate identity and access management.

Organizations have to choose cross-platform solution providers for seamless integration. Priority needs to be given for providers offering better coverage across multi-cloud environments. Security teams also need to establish controls on multi-cloud layers and consider the applications in different situations.
