Cloud Security protects data and applications hosted in public, private or hybrid cloud environments from cyberattacks, data breaches and system outages. It includes measures such as implementing a zero trust approach to the security of all cloud-based assets and applications, dividing cloud networks into separate independently secured “zones” to prevent data breaches or attacks from spreading across the entire infrastructure, and using encryption technology to protect sensitive data in transit and at rest in the cloud.

Many of the same cybersecurity issues that plague on-premises data centers persist in the cloud. For example, human error and a lack of visibility into the complex systems that run in the cloud can lead to misconfigurations that expose cloud data to hackers. A significant portion of breached records can be attributed to such mistakes, which underscore the importance of robust security measures and best practices.

In addition, the multi-tenancy architecture of most public clouds makes it difficult to secure individual tenant environments. This issue can leave regulated data vulnerable to hackers in the same way that unsecure data can be compromised, leading to compliance violations and hefty fines. To address this challenge, organizations should implement security solutions that can discover, classify and de-identify regulated cloud data to ensure compliance with regulations and protect intellectual property in the cloud.

Robust cloud security measures also include protecting against data breaches and cyberattacks with disaster recovery solutions that replicate data and applications in multiple locations to expedite restoration and minimize downtime. These tools can be complemented by advanced capabilities like generative AI, which enables more effective threat detection and response in multicloud environments.
