Zero trust security framework

What is Zero Trust Security Framework?

As businesses increasingly go digital, the need for robust security measures becomes more critical. The zero trust security framework provides a comprehensive approach to security that can help your business stay safe in a constantly-changing online world.

In this guide, we’ll discuss zero trust security and how you can put it into practice in your organization. Let’s get started!

Zero Trust Security Framework

The Zero Trust concept is about end-to-end security, which builds trust between individual devices in the enterprise network and the cloud. The Zero Trust Security Framework is a set of practices and recommendations. This addresses security challenges in a zero-trust environment that can be applied to any organization regardless of size or industry.

A Zero Trust framework is an approach to security that assumes that any entities accessing a network or system are untrusted. Thus, must be treated accordingly. The Zero Trust Security Framework approach has been developed with an emphasis on cloud and mobile computing.

However, it applies to any environment where users are granted access to information via a network they do not control. The name of the concept comes from the idea of “zero trust” as opposed to “trust but verify”. So, there is no reliance on predetermined rules, roles, relationships, or other factors that denote trustworthiness.

SaaS or MAPP Application Platform

SaaS and MAPP are also good options for Zero Trust hosting cloud-based services. These are such email, search, and collaboration platforms. Also, SaaS and MAPP provide not only the application itself but also its operating system.

Thus, it makes it easier to update and patch their software than if you were running it on your server. This concept includes several practices for implementation:

1. Ongoing monitoring of network traffic to detect and prevent unauthorized access.

2. Ongoing assessment of security configuration settings. So, to ensure that they are consistent with current corporate policies and risk tolerance.

3. Strong authentication and authorization controls, this includes multifactor authentication, to ensure that only authorized users access the network.

4. Enforcement of least privilege at every level of the network.

5. Automated responses to detected incidents designed to contain breaches. Also, to mitigate their impact and facilitate timely recovery.

Access Authentication Control

Conventional network security solutions use static policies. These are such as firewalls, intrusion prevention systems (IPS), and virtual private networks (VPN). Hence, it determines what traffic to allow or block.

But this approach does not work against new cyber threats. These security risks are advanced persistent threats (APT), advanced malware, and data breaches caused by employees. In addition, this approach is ineffective when organizations adopt cloud-first strategies for their critical applications and sensitive data.

This authentication process can be implemented through several methods including:

1. User/device authentication using passwords or other authentication mechanisms.

2. Authentication of devices through digital certificates

3. Authentication of users through various risk-based authentication models

4. Authentication of users through social media entities into the system.

Context-Aware Access Control

Access decisions should be driven by context. Based on context, different security controls are applied to enforce policies for different entities based on their identity and risk profile. For example, an employee should have access to his/her files.

However, it does not have access to proprietary information (such as intellectual property) of the organization that he/she doesn’t own personally. In addition, security controls should be applied based on both static and dynamic contexts. Thus, it includes location, time of day, and application being accessed with application to optimal zero-trust protection.
