Zero-Trust Model
Why Zero-Trust?
Traditional security approaches assume that anything inside the corporate network can be trusted. The reality is that this assumption no longer holds true, thanks to mobility, BYOD (bring your own device), IoT, cloud adoption, increased collaboration, and a focus on business resiliency. A zero-trust model considers all resources to be external and continuously verifies trust before granting only the required access.
What is Zero-Trust?
Zero trust is a strategic approach to security that centers on the concept of eliminating trust from an organization's network architecture. Trust is neither binary nor permanent. We can no longer assume that internal entities are trustworthy, that they can be directly managed to reduce security risk, or that checking them one time is enough. The zero-trust model of security prompts you to question your assumptions of trust at every access attempt.
Do I need Zero-Trust?
With the increase of ransomware, supply change attacks, and the wide surface of attack vectors in todays network, the best way to defend our assets against cybercriminals, is adopting a zero-trust model where every single access must be granted. Security teams can make it harder for attackers to collect what they need (user credentials, network access, and the ability to move laterally), and users can get a consistent and more productive security experience--regardless of where they are located
