In order to secure cloud computing, there are several factors and steps to consider:
Identify the resources: Determine which data, services, or applications you plan to move to the cloud. This will help you assess the specific risks associated with each resource.
Assess sensitivity to risk: Evaluate the sensitivity of the resources to risks such as loss of privacy, unauthorized access, data loss, and availability interruptions. Different resources may have different levels of sensitivity and require different security measures.
Consider cloud types: Understand the different cloud deployment models (public, private, hybrid, shared community) and evaluate the associated risks for each resource. Consider where the data and functionality will be stored and maintained within the chosen cloud type.
Understand the service model: Different cloud service models (IaaS, SaaS, PaaS) have different levels of security responsibilities. Determine which model you will be using and understand the security responsibilities of both the cloud service provider and the customer at each level of the service stack.
Evaluate the cloud service provider: If you have selected a specific cloud service provider, assess their security systems and practices. Understand how data is transferred, stored, and moved in and out of the cloud. Consider the provider's certifications, credentials, and security resources.
Establish security boundaries: Define the security boundaries between the responsibilities of the cloud service provider and the customer. Understand where the provider's responsibilities end and where the customer's responsibilities begin. This helps determine the security mechanisms that need to be implemented by each party.
Map security mechanisms: Map the security features, compliance auditing, and other requirements of your specific cloud service model to the application you are deploying. Identify any missing security features that would be present in an on-premises deployment and seek replacements in the cloud computing model. Consider industry compliance standards that may apply to your organization.
Maintain accountability: Ensure that accountability for security is assigned to the appropriate parties. When contracting with a cloud service provider, make sure they remain accountable for the security measures you require.
Stay informed: Stay updated on the latest security best practices and technologies in cloud computing. Regularly review the security resources and recommendations provided by industry organizations such as the Cloud Security Alliance (CSA) and follow the guidance provided by reputable sources.
By following these steps and implementing appropriate security measures, you can enhance the security of your cloud computing deployment.
