Cloud security is about securing your cloud services and your data hosted in cloud environments, and comprises a multitude of individual measures that protect against risks such as data loss, service failure or unauthorized access while using cloud services. A consistent implementation of cloud security will minimize the risk of failures, data loss, hacker attacks or unauthorized access to data by considering:
- the access to the data
- the physical security of the data center
the logical security of the servers
- the security of the network structures and access
the security of the platform and the applications
- Data security
- the secure management of keys and access codes
One of the biggest factors in carrying out successful cloud security operations is ensuring everyone is on the same page. When deploying cloud security, it is crucial that your organization and the cloud solution provider you’ve chosen to move forward with, understand each other’s needs, responsibilities, and respective roles in the process.
Looking at our data protection example above, this would require your cloud provider to prove that they fulfill the data protection requirements and have appropriate emergency and recovery processes in place. In addition, you must have a documented process that controls user rights and change management. Contractually agreed regulations can be, for example, Service Level Agreements (SLAs), which assure customers of certain availabilities and, in the event of malfunctions, define response times, recovery times and alarm chains or escalation levels. In addition, agreements can be made about regular exercises to be carried out on security-related events. Making the right choice of a cloud service provider depends up on aligning strategies for compliance, security and in the worst case ensuring your data is available and recoverable, even if the provider goes out of business.
