Ascertaining Security Requirements

By Cloud Computing Outlook | Wednesday, April 24, 2019

As more organizations move to the cloud, cloud service customers are encouraged to understand how the cloud will affect their privacy, security, and compliance. Cloud service clients need to understand how their cloud service provider delivers a secure solution. Cloud service clients need to consider their new role in the security of the cloud. Some cloud service clients mistakenly believe that their cloud security responsibilities also switch when they migrate to the cloud.

While the number of services available increases, government agencies are more ready to move their data storage and computing to the cloud. Agencies should be more cautious than ever when moving to the cloud to ensure they maintain adequate levels of security. It's no secret that security issues are prompting agencies to extremely deploy private clouds for sensitive high-impact data which cannot be pushed into the public cloud. Private clouds provide agencies with full control over their data and where they reside over their lifecycle as well as control over who has sole rights to the cloud infrastructure.

Many agencies are transforming into a hybrid cloud environment for less sensitive data and workloads. In some instances, CSP security can be used for the hybrid cloud to protect data. Moreover, as the hybrid model combines on-site infrastructure with public cloud infrastructure, agencies need to ensure that security forces between infrastructures are managed seamlessly. Security must improve with them as cloud environments evolve. It is a dynamic process that needs an understanding of cloud infrastructure, the services and protection provided, the key management needed for security services, as well as the use cases and awareness of the growing threat vectors around cloud data use.

The simple reality is that a cloud model dramatically increases threat vectors. Insider threats are more likely, as more people have the authority to maintain the infrastructure of the company. Consequently, agencies must be concerned not only with threats within the company, but also within the cloud itself. This also promotes the model of shared responsibility, where the CSP is responsible for infrastructure security, but users are accountable for data security. It is both the responsibility of cloud service suppliers and cloud customers to protect data. It is also worth noting that it is possible to outsource the execution of individual security management tasks, but accountability cannot. It is always the customer's responsibility to confirm that security requirements are met.
