Cloud Security refers to the tools and services used by IT teams to protect data, applications and systems that reside in the cloud. The four central pillars are visibility, access control, threat prevention and compliance.

Cloud security is increasingly crucial for businesses of all sizes as they continue to move their operations into the cloud. With sensitive business content such as customer orders and secret design documents being stored in the cloud, preventing leaks and cyber threats is essential for businesses looking to preserve trust, reduce risk of reputational damage and improve ongoing business productivity.

The most common and effective cloud security strategies include encryption in both communication channels and permanent storage. It’s also important to educate employees not to use unauthorized software or shadow IT for work purposes as this can expose company networks and devices to malicious actors.

In addition to this, cloud users should be implementing policies and monitoring solutions such as firewalls, CASBs, identity management, file integrity monitoring, anomaly detection and malware prevention systems to protect their data and system from the multitude of different attacks. Finally, a good cloud security strategy must always be backed up with a disaster recovery plan in case of a server or data center failure.

In the context of the NSA scandal, it is also crucial to remind all cloud users that their data may be stored on servers in the USA and therefore subject to American laws, which provide less protection for user privacy than European law. This is why choosing a cloud service provider with strict policies and solid governance practices is essential.
