Cloud Computing Security: Addressing Data Protection Challenges
Despite its many benefits, cloud computing also raises significant concerns, particularly related to data security. As organizations store more sensitive data in the cloud, protecting this data from cyber threats becomes a top priority. The shared responsibility model, where the cloud provider secures the infrastructure and the customer is responsible for securing data and applications, requires businesses to implement robust security measures.
1. Zero-Trust Security Model
One of the most promising solutions for improving cloud security is the Zero-Trust security model. A Zero-Trust model assumes no user, device, or application is trustworthy by default, regardless of their origin. This model requires continuous verification of users and devices before granting access to data or systems, reducing the risk of unauthorized access.
Zero-Trust is gaining traction among cloud providers as businesses look to protect their cloud environments from evolving cyber threats. With this model, organizations are less likely to be exposed to internal or external threats, and sensitive data remains more secure.
