The main advantage of taking a zero-trust approach is that it protects businesses from all sides, especially from within.
FREMONT, CA: Zero-trust is a security model that combines tight identity verification and explicit authorization for every person or thing attempting to access or utilize network resources, regardless of whether the person or entity is inside or outside an enterprise's network perimeter.
The Advantages of a Zero-Trust Model
The main advantage of taking a zero-trust approach is that it protects businesses from all sides, especially from within. Traditional security methods, such as defense-in-depth, have traditionally focused on network perimeter protection. Many of today's breaches originate from within, whether by workers or threats that have infiltrated the network via email, browsers, VPN connections, and other means. For someone who already has network access, data exfiltration can be simple. To address this, zero trust disables access to anybody and everything until the network can verify the identity. Then it keeps track of how one is utilizing data and, if necessary, revokes the authorization to transfer it elsewhere.
The Foundations of a Zero-Trust Network
As its name implies, zero trust is based on the idea that nothing should be taken at face value and that everything should be double-checked. A zero-trust approach is made up of numerous technologies and best practices that fall under this umbrella. Here are some of the most important principles:
Continuous monitoring looks at how people and things interact with data and other systems. This instance allows risk-adaptive security controls to automatically customize enforcement based on people's actions, ensuring that people are who they say they are.
