Cloud computing is becoming increasingly popular, helping various businesses better manage their data. It offers several benefits, including accessibility, convenience, flexibility, cost savings, recovery, and maintenance. However, cyberattacks are continuing to threaten the security of cloud systems and have more than doubled in 2019. It is therefore important to consider how secure your company is on the cloud. Here are five points all company leaders must know about cloud security:
1. Shared Resources for Multi-Tenancy Cloud Customers
The shared resources that your cloud service provider will allocate to your data are referred to as multi-tenancy. Instead of having a physical infrastructure dedicated to a single application or organization, the cloud utilizes virtual servers that sit on the same box and share resources between containers. You should thus make sure that your cloud service provider secures your containers and prohibits unauthorized access to your data.
2. Data Encryption During Both Transmission and at Rest
Because you will be accessing data from remote locations, your service provider must encrypt all your company’s information, whether at rest in the virtual environment or when transmitting it over the internet. However, even if the service provider’s applications can access all your information, it should still be inaccessible to anyone else other than your company's resources. Make sure to ask your service provider about what encryption they used to secure your data to better protect valuable information.
3. Centralized Visibility of Your Cloud Infrastructure
Oftentimes, it may not be enough to trust service providers, which means you should also verify that your data remains secure in their host environments. You can use cloud workload protection (CWP) tools, which provide centralized visibility of all your information so you can gain better oversight of the environment. We also recommend asking your cloud provider for security tools like network-traffic analysis or cloud environment inspection for malicious content.
4. A Secure and Integrated Access Control Model
Access control models continue to pose a significant risk in cloud environments. Thus, your provider's cloud-based security must include a management solution for maintaining access privileges and controlling user roles.
5. Managing Vendor Sprawl Using Threat Intelligence
Lastly, if you find yourself working with multiple vendors with their own cybersecurity frameworks in complex cloud deployments, you should use threat intelligence solutions that can give you a clear picture of all your vendors, along with the most recent threats that could jeopardize your business systems. A threat intelligence tool will collect and curate data from various cybersecurity research firms to alert you of any vulnerabilities in your vendor's system. Understanding the entire threat landscape is therefore essential for any organization considering a full cloud migration.
