Thanks to a rapid shift to remote work, Zero Trust is finally garnering the attention it deserves. With its tailored controls, micro-perimeters and trust-nothing approach to access, Zero Trust gives CISOs confidence that their security program can secure their remote workforce and meet regulatory compliance requirements.
Built on an identity-centric framework for security, Zero Trust completely transforms both current and legacy IT models. My experience implementing Zero Trust has shown me that, while the process to implement a complete architecture takes time, the transformation is worth the effort and the benefits will be realized throughout the journey.
What is Zero Trust?
The Zero Trust framework verifies that only trusted identities have access to systems, networks, applications and data at every step, based on an identity's role or operational need. Trusted identities are separate authentication and authorization planes that make up the overall trust of a user, their devices, and their access. Examples of identity types are the user, device, applications, data, network traffic and behaviors.
Zero Trust can help companies prevent and contain an incident before suffering a catastrophic breach. If one identity type is compromised, the others will not be affected. This framework has been essential in securing remote workforces that transitioned seemingly overnight due to the need to protect employees, the business systems and applications, and data no matter where it is or where they are.
Building a Strategy for Implementation
Zero Trust is the next evolution of the security model, and charting a strategy is essential to successfully making the transition. When building a strategy, there are five key components to consider:
Begin Your Zero Trust Journey Today
Transforming your technology infrastructure can be long, tedious work, and you will operate in a hybrid Zero Trust/legacy mode for a time. Begin by implementing Zero Trust principles, process changes and solutions for the highest-value data assets. Do not discount the incremental gains. Simply implementing identity and access management (IAM) or MFA, for example, are invaluable and important steps in protecting your business today and towards achieving your ZT goals and objectives. While it could be a challenging journey, the risk reduction for the overall business will give CISOs peace of mind that their workforce is properly secured no matter where they are.
