The National Security Agency has released a guidance document on implementing Zero Trust within networks. The paper “Cybersecurity Information Sheet: Embracing a Zero Trust Security Model” explains what Zero Trust is, why it is necessary, and how to get started.
What is Zero Trust?
Traditional networks with users located inside a perimeter were usually based on a “trust but verify” security model built on everything’s implicit trust. If users had credentials to enter the perimeter, they would have visibility and access to everything assigned to their business roles. Zero Trust turns that model around and creates an environment of “never trust, always verify” build on explicit trust and restricted access. The National Institute of Standards and Technology (NIST) defines several tenets and assumptions that should form any Zero Trust use case first principles. For further review, this document is provided on our website.
What is Zero Trust Architecture?
A Zero Trust Architecture (ZTA) is the technical and operational implementation of the Zero Trust principles. The practical implication is that users will have the access they need, and security gaps will be avoided or corrected. Advanced threats are less of a risk in a ZTA network because Zero Trust Architecture requires ongoing session verification using real-time data points such as user identity, device health, workload, and device identity. ZTA also makes use of micro-segmentation, which reduces the space an intruder can traverse through the network.
Now is the time to get started with ZTA
The IT world has never been more dangerous in terms of cybercrime. Ransomeware is surging, with damages estimated at over $1 billion worldwide. In August 2020, the FBI reported that Business Email Compromise (BEC) scams cost businesses more than $26 billion worldwide between 2016 and 2019
Cyberattacks and malicious software are evolving, becoming more dangerous every day. Zero Trust Architecture protects your data, customers, employees, intellectual property, supply chain, and everything else associated with your network.
