The organization that need to reliably prevent the exfiltration of sensitive data and want to improve their system to defend again modern cyber threats can consider a Zero Trust architecture. This Zero Trust is introduced by analyst firm Forrester Research that alternative architecture for IT security.
So Zero Trust, Zero Trust Network or Zero Trust Architecture refers to security concepts and threat model that no longer assumes that actors, systems or services operating from within the security perimeter should be automatically trusted, and instead must verify anything and everything trying to connect to its systems before granting access. The term was coined by a security analyst at Forrester Research. This Zero Trust is built upon 5 fundamental assertions:
- The network is always assumed to be hostile.
- External and internal threats exist on the network at all times.
- Network locality is not sufficient for deciding trust in a network.
- Every device, user, and network flow is authenticated and authorized.
- Policies must be dynamic and calculated from as many sources of data as possible.
Zero Trust to gain visibility and context for all traffic across user, device, location and application plus zoning capabilities for visibility into internal traffic. To gain traffic visibility and context, it needs to go through a next-generation firewall with decryption capabilities. The next-generation firewall enables micro-segmentation of perimeters and acts as border control within your organization.
While it’s necessary to secure the external perimeter border, it’s even more crucial to gain the visibility to verify traffic as it crosses between the different functions within the network. Adding two-factor authentication and other verification methods will increase your ability to verify users correctly. Leverage a Zero Trust approach to identify your business processes, users, data, data flows, and associated risks, and set policy rules that can be updated automatically, based on associated risks, with every iteration.
