How secure is your data? Are you aware of the risks involved in storing sensitive information online? In this post, we will answer a top security question like “How Zero Trust Security Is Design?” and how it protects your data.
The Design of Zero Trust Security
Zero Trust security is a way to secure the network by designing it. In a way that minimizes or eliminates any trust among users, devices, and applications.
In a Zero Trust security model, every user, device, and application is considered untrusted. This means that there is no trust placed on users or their devices.
As every user or device is untrusted, they are required to prove their identity. Before they can access the network or its resources.
Once the identity has been verified and the user/device has been authorized to access the network. Then users and their devices are only granted access. To those resources that have been explicitly assigned to them.
Principles Zero Trust Security
The following are the principles of Zero Trust security:
- Deny by Default
- Require Elevation
- Segment Everything
- Least Privilege
Let’s discuss each in detail.
Deny by Default
This is the first principle of Zero Trust security. In the Zero Trust security model, we start with the assumption that every user or device is untrusted. And, we start by denying them access to the network.
The network and its resources are off-limits to all users/devices unless they prove their identity. And, are authorized to access the network and its resources.
This principle is similar to how firewalls work. However, it is more granular than what firewalls offer.
In this scenario, firewalls block all traffic from entering the network. However, in a Zero Trust security model, we allow only authorized traffic into the network. And, block unauthorized traffic from entering the network.
Require Elevation
Once you are granted access to the network. Then you need to be granted access to other resources individually. An authenticated user/device or an authenticated application will be granted access only to those resources.
Segment Everything
The Zero Trust security model segments every resource in the network. Such that users/devices and applications can only access the resources that are explicitly assigned to them.
Least Privilege
It is the principle of least privilege. In the Zero Trust security model, it is assumed that every user/device and application is untrusted. And, granted only the minimum level of privilege to perform tasks.
How Does Zero Trust Security Work?
Zero Trust security works by denying access to all users/devices and applications. Unless they prove their identity. And, then authorize them to access the network and its resources individually.
This means that every user or device is required to authenticate before accessing the network. And, there is no trust placed on anyone or anything.
Including users or their:
- devices, or
- applications running on their devices
Also, even internal data center systems are considered untrusted.
Every device is considered untrusted in a Zero Trust security model. And, is required to prove its identity. And, then be authorized to access the network.
This includes both internal systems as well as external systems.
Also, every user and application is only granted access to resources that are explicitly assigned to them.
In a Zero Trust security model, no one is trusted. This means that even users and their devices are considered untrusted. And, every device is required to prove its identity. Before being granted access to the network or its resources.
