Traditional secure remote access solutions like VPNs don’t work anymore for today’s world where users, devices, and applications are highly distributed and dynamic. We need three foundational building blocks to provide a complete solution:
1. Quantified Trust: User and device trust are no longer black or white, but rather like shades of grey where depending on the security posture the same user and device may be allowed different levels of access.
2. Continuous Authorization: The channel cannot be validated with just one-time authorization, but rather needs to be continuous authorized based on zero day attacks, unauthorized user activity.
3. Decentralized Enforcement: The access enforcement cannot be centralized to handle the large scale and security concerns of modern enterprises. We need a highly distributed architecture that scales with applications and clouds.
Access control is a fundamental component of data security that dictates who’s allowed to access and use company information and resources. Through authentication and authorization, access control policies make sure users are who they say they are and that they have appropriate access to company data. Access control can also be applied to limit physical access to campuses, buildings, rooms, and data centers.
