5 Must-Knows to Manage Risks
Cybersecurity breaches have become all too common, putting public health, individuals’ private information, and companies in jeopardy.
With cloud computing prevalent in business as a way to store and share data, workloads, and software, a greater amount of sensitive material is potentially at risk. Therefore, company leaders need to prioritize cloud security and know how to manage the risks.
Cloud adoption is a business model that provides convenience, cost savings, and near-permanent uptimes compared to on-premises infrastructure. But cyberattacks continue to plague organizations of every size and moving your IT infrastructure and services to cloud environments requires a different approach to traditional deployments.
A private cloud keeps all infrastructure and systems under the company’s control, while a public cloud hands over the responsibility to a third-party company. In hybrid deployments, which most organizations adopt, some services are in the public-cloud infrastructure while others remain in the company’s data center. Regardless of which cloud deployment you choose, you should know the cloud-security basics or consult with cybersecurity experts before migrating to the new environment.
Here are five points company leaders need to know about cloud security to help manage their risks.
• Shared resources for multi-tenancy cloud customers. Multi-tenancy refers to the shared resources your cloud-service provider will allocate to your information. The way the cloud and virtualization works is: instead of physical infrastructure dedicated to a single organization or application, virtual servers sit on the same box and share resources between containers. A container is a standard unit of software that packages code and helps the application run reliably from one computing environment to another. You should ensure that your cloud-service provider secures your containers and prevents other entities from accessing your information.
• Data encryption during transmission and at rest. Accessing data from a remote location requires that a company’s service provider encrypt all the business’ information — whether at rest in the virtual environment or when being transmitted via the internet. Even when the service provider’s applications access your information, it should not be readable by anyone else except your company’s resources. To protect your information, ask your service provider about what encryption they use to secure your data.
• Centralized visibility of your cloud infrastructure. It’s not enough to trust service providers; you will also want to verify that your data remains secure in their host environments. Cloud-workload protection tools provide centralized visibility of all your information so you can get adequate oversight of the environment. Ask your cloud company if it can provide you with security tools such as network-traffic analysis and inspection of cloud environments for malicious content.
• An integrated and secure-access control model. Access-control models remain a major risk in cloud environments. Your provider should have cloud-based security that includes a management solution to control user roles and maintain access privileges.
• Vendor-sprawl management with threat intelligence. In complex cloud deployments, you may end up using different vendors, each with its own cybersecurity framework. Threat-intelligence solutions can provide you with clear insight into all your vendors and the latest global threats that could put your business systems at risk. A threat-intelligence tool will gather and curate information from a variety of cybersecurity-research firms and alert you to any vulnerabilities in your vendor’s system.
For any organization that is considering a complete cloud migration, understanding the entire threat landscape is essential. A team of cybersecurity experts can assist with the planning and oversight of your cloud migration to mitigate risks and establish the necessary controls.
