Zero Trust Security

What Is Zero Trust Security?

Zero trust network security places more emphasis on protecting data and users who access the system rather than the device they use to do it. It takes into account no user, device, or request should be given immediate trust but instead should be verified before being granted access to only what they require. It requires various components like authentication, authorization, micro-segmentation and encryption as well as least privilege access management to further strengthen protection against potential malicious actors. By employing such an approach to network protection organizations can make sure their sensitive data remains safe from potential risks.

How Does Zero Trust Work?

Zero trust works by verifying every user, device and request before authorizing access. This model relies on least privilege access: giving only what is necessary to perform their jobs effectively without giving access to unnecessary sites or people. Zero trust includes components like authentication, authorization, micro-segmentation and encryption to prevent malicious actors from accessing sensitive data as well as identity management to verify whether users are who they say they are - so organizations using zero trust security models can rest easy knowing their sensitive information remains safe from prying eyes.

Do I Need Zero Trust?

Organizations of all sizes can gain from adopting a zero trust security model. It is particularly beneficial for organizations that employ remote workers who require access to sensitive data while away from the office, or those dealing with customer or financial data that is especially valuable - thus protecting it against malicious actors. Businesses using zero trust network access and other components of zero trust architecture to safeguard data protection ensure they can effectively shield their valuable customer and financial data assets from attack.

What are Zero Trust Security Benefits?

Least privilege access

By verifying every user, device and request before granting access, zero trust helps eliminate security threats by granting minimal access necessary to get the job done.

Improved authentication

Zero trust relies on identity management to ensure that users are who they say they are. This helps prevent malicious actors from accessing sensitive data.

Increased visibility and control

By utilizing zero trust network access and other components of the zero trust architecture, businesses can gain visibility and control over their network activity. This increases security as any suspicious activity can be identified quickly.

Micro-segmentation

Organizations can ensure that different parts of their network are completely isolated from one another with micro-segmentation. This keeps outsiders from moving laterally across the network and gaining valuable data.

What are the Principles of the Zero Trust Model?

The Zero Trust Model encompasses six principles. These principles include:
1

Assume breach

Always assume that malicious actors have already gained entry to the network, and design systems accordingly.

2

Verify explicitly

Before providing access, thoroughly research every individual, device and request before authorizing access.

3

Limit access

Only grant the minimum level of privilege needed for completion of tasks.

4

Microsegmentation

Isolate different parts of your network from each other to prevent any unwanted lateral movement across it.

5

Limit access lifetimes

Always assume that malicious actors have already gained entry to the network, and design systems accordingly.

6

Examine All Communications for Potential Threats

Utilize tools like zero trust network access to monitor communications for any suspicious activities or signs of danger.
