Getting Cloud Right: The 4 Crucial Aspects of Cloud Security
The 4 Crucial Aspects of Cloud Security
1. Data Security
As data moves from a company’s secure perimeter to the cloud, organizations must move to a layered model that ensures the proper isolation of data in the shared, multitenant cloud. The data must be encrypted using methodologies such as cryptography and tokenization and secured by controls like multi-factor authentication and digital certificates. Monitoring tools must also be deployed to reinforce security tools such as intrusion detection, Denial-of-Service (Dos) attack monitoring, and network traceability tools. It’s imperative for organizations to stay abreast and adopt security innovations to gain complete visibility of their data and information.2. Compute-level Security
Organizations must employ compute-level security for end systems, managed services, and various workloads and applications in the cloud environment. The first component of compute-based security is automated vulnerability management, which involves identifying and preventing security loopholes across the entire application lifecycle. The second component is providing operational security for anything considered to be a compute system or compute workload. Robust cloud security requires automatic and continuous inspection and monitoring for detecting any anomalous or malicious activity.3. Network Security
Securing networks in the cloud are different from securing a traditional network. Network security in cloud computing involves four principles:- Micro-segmentation or isolation of zones, workloads, and applications using layers of firewall
- Network controls for traffic flow down to the user level
- Applications should use end-to-end transport-level encryption
- Using encapsulation protocols such as SSH, IPSEC, SSL while deploying a virtual private cloud
