When implementing zero trust security, how should vulnerability scans for a cloud-based infrastructure be conducted?

When implementing zero trust security, conducting vulnerability scans for a cloud-based infrastructure automatically is essential. Zero trust is a security model that requires strict identity verification for every person and device trying to access resources on a private network, regardless of whether they are inside or outside the network perimeter. Automatic vulnerability scans align with this principle by ensuring that the security posture is continually assessed without reliance on human intervention.

In a cloud environment, where assets can frequently change, automated scans can be scheduled to run at regular intervals and can quickly identify new vulnerabilities as they arise. This allows organizations to respond promptly to emerging threats. Furthermore, automated scans can be integrated into continuous integration and deployment pipelines, ensuring that security is considered throughout the entire software development lifecycle.

The other approaches, such as manual scans, annual assessments, or scans conducted only as needed, may not provide adequate protection in a fast-paced cloud environment where vulnerabilities can proliferate rapidly. Manual scans might overlook critical issues due to human error or oversight, and annual scans would leave the system vulnerable for long periods without updates on its security status. Similarly, only conducting scans as needed might lead to significant gaps in threat detection. Automated scans enable organizations to maintain a proactive security posture throughout their cloud infrastructure, consistent with zero trust principles.
