Cloud storage services store data in “the cloud,” a collection of servers connected by and to the Internet. Instead of storing data on local servers, companies upload that data to cloud servers where it can be accessed by multiple users from multiple locations.
Data stored in the cloud needs to be at least as secure as data stored on-premises. Just as cloud storage is an outsourced solution for storing digital data, cloud security is an outsourced solution for securing that data.
Cloud security involves several technologies and processes designed to ensure that only authorized users have access to the specific data stored in the cloud. These best practices include file-level encryption, advanced firewalls, intrusion detection, and physical security that provides 24/7 monitoring of cloud data centers.
