Before Deploying to the Cloud Think Security
Today, more organizations are deploying to the cloud, but security still remains a major concern. However, in the past couple of years security services and tactics have improved, allowing more enterprises to migrate to the cloud. Before making your final deployments to the cloud review your enterprise security architecture. Moreover, you must understand the current security posture of your compliance, its assets, and audit.
Before Making Your Transition To The Cloud, Consider These Security Measures
1. What are your data residency requirements?
Your IT department must clearly identify your operational data residency requirements and classify your transaction requirements. You must design a cloud strategy that meets these requirements. However, part of your consideration centers around the cloud providers’ being able to ensure compliance to your data residency needs.
2. Following strict standards when migrating sensitive data to the cloud
Before migrating to the cloud make sure you comply with Industry and governmental standards such as HIPPA, PCI compliance, and EU Data Protection 2.0 regulations. If your company deals with highly regulated data you have to include a stringent design and governance to follow regulations and legal mandates. This also depends on the applications your organization is considering for cloud migration. Therefore, you must have a detailed checklist of all requirements that must be developed and maintained. This ensures your organization is complying with the laws and industry regulations.
3. Your IT department needs periodical security reviews
Your IT department needs to monitor your cloud-deployed assets and do a thorough vulnerability assessment to address potential vulnerabilities. Your corporations IT assets are in constant danger of new attacks and it is essential that you constantly monitor your assets for threats. Therefore, it is recommended that your IT department use application penetration testing and periodic vulnerability analysis to monitor your assets. If your IT department discovers vulnerability you need to protect your network with WAF until they are fixed. Also, your IT department needs vulnerability tools to monitor SQL injections.
4. Define the role of your cloud service provider SLAs and their accountability
Your company has to clearly define the roles, accountability, and responsibilities for everyone involved. To facilitate your work you should consider hiring a CSB to help you define all specialized services and combine them into an integrated service. This helps your IT department define a single point of accountability. Otherwise, the multiple niche technology vendors will become too complex to manage.
5. Design a multi-tenant deployment solution for your data
Today, multi-tenant public cloud environments can use virtual machines (VMs) that can co-exists with your VM hosting other applications. Therefore, your intra-VM is exposed to potential threats. You need a clearly defined security solution to encrypt your data while in transit and at rest.
6. You must understand your network configuration and potential vulnerabilities
Your IT security team needs a complete understanding of your network security profiles for all your VMs and network traffic ports. Therefore, you must invest in a software-driven security configuration to manage your network security. The software watches your network traffic for threats and malware.
7. Your IT department must have consistent user management and access controls for your cloud services
Cloud based service providers must comply with the Cloud Data Center Security Standards ISO 27001. Your organization needs to follow the same security standards to ensure your data, users and assets are protected. Your IT department top concern is to manage users. Your systems have human interactions at different levels despite increased automation. Your cloud administrators have privileges that provide them access to your systems and user data. Your user management systems must have security measure to establish identity and access controls. You must have activity audit logs on your system to ensure tractability.
