Given the stringent core security requirements, cloud security cannot remain static and must continuously evolve to adapt to changing technologies. Outlined below are key reasons that highlight the need for dynamic cloud security: 

• Increased Data Availability: With the increased volume of data and shift towards virtualization and remote work, information is more accessible than ever, which increases the risk of data being replicated anywhere and everywhere. 
• Third Party Risks: Traditional access controls are often ineffective against privileged users, who can bypass standard protections. Enhanced security measures are required to monitor these users, ensuring that their privileged status does not become a liability.
• Securing Cross-Enterprise Collaboration: Security controls must extend beyond organizational borders, managing multiple identities and access levels across complex supply chain networks while also ensuring regional compliance.  
• Need for Automation: Manual responses to security threats have become impractical due to the compounded volume of data access and sharing risks. Automating cloud security reduces the need for manual intervention, enabling more consistent and reliable implementation of protective measures. 

Therefore, organizations require technology that can dynamically enforce cloud security measures. One such effective method would be to adopt the Zero Trust Architecture and implement a Policy Engine that makes real-time authorizations decisions based on attribute-driven policies, which surpasses traditional static methods in adapting to business, security, and compliance requirements.
