Cloud Security protects data and applications from ever-evolving threats in the cloud. Without it, organizations can face substantial financial losses, reputational damage and legal repercussions. Fortunately, there are best practices and technologies that can help businesses implement effective cloud security solutions.

The Cloud Environment

Cloud environments offer significant benefits for businesses, including faster access to critical apps and data, improved content management, and enhanced productivity for remote users. However, these advantages come with a unique security challenge because clouds don’t have clear perimeters and have more interconnected systems than traditional on-premises networks. This makes them an attractive target for cyberattacks.

Because of this, many organizations have adopted a hybrid or multi-cloud strategy that uses a mix of public and private clouds. While most cloud providers manage the underlying infrastructure, customers take on some of the network security responsibilities, such as securing their own data and applications. This is known as the shared responsibility model.

In most cases, CSPs limit the boundaries between customer accounts to prevent one company’s data from leaking into another’s. The boundaries between the customer’s environment and the provider’s environment are also reinforced with encryption, limiting the risk of sensitive information being exposed to malicious actors.

Effective cloud security requires advanced threat detection and prevention capabilities. They should include identity and access management, which authenticates users and devices to ensure that they are who they say they are. This includes multi-factor authentication and biometrics, as well as granular authorization controls for applications and resources. These controls should be integrated with a next-generation firewall that utilizes application-aware filtering to detect and block threats.
