Cloud hosting differs from traditional hosting in that information is stored in a network of virtual and physical servers versus a single, physical server onsite. The methods to secure cloud hosting has shifted as the popularity of cloud computing has grown.
Preference for computing in the cloud saw a slow build over the years as originally enterprises didn’t trust the security of it. Today, the cloud is the predominant method for computing as it is cost-effective, scalable, flexible, and more secure than traditional networking. The cloud is more guarded than traditional computing; “by distributing server data across redundant servers, information hosted in the cloud is protected against hardware failure.” However, hosting in the cloud still possesses vulnerabilities, such as malware and ransomware. View the steps to secure cloud hosting in the list below.
Steps to Secure Cloud Hosting
- The Cloud Council advises for enterprises to verify that their “applications and data hosted in cloud services are secured in accordance with their security and compliance policies to verify that the cloud service agreement between the customer and the provider, along with associated documents such as the service level agreement (SLA), contain all their requirements.”
- Maintain government regulations, such as the European Union’s General Data Protection Regulation (GDPR), and protect users’ data and privacy.
- Implement Network Performance Management, Application Performance Management, and/or Unified Performance Management tools to monitor the cloud network for any suspicious activities or traffic roadblocks.
- Use multi-factor authentication.
- Encrypt data.
- Add both physical and virtual firewalls to secure cloud hosting.
- Use key management and key rotation.
- Apply tokenization as an alternative to or along with key management.
- Install a Cloud Access Security Broker (CASB). Gartner defines CASBs as “on-premises, or cloud-based security policy enforcement points, placed between cloud service consumers and cloud service providers to combine and interject enterprise security policies as the cloud-based resources are accessed.”
