What is Zero Trust Security and Benefits in implementing Zero Trust Security Model

An Overview:

 The concept of Zero Trust Security was introduced by John Kindervag, during his occupancy as a vice president and principal analyst for Forrester Research in 2010.

Zero Trust Security is based on the “never trust, always verify” approach which keeps an eye on access to your DaaS(Data as a Service). According to Zero Trust Security, trust is seen as a vulnerability.

Financial services organizations are marching towards the Zero Trust approach in which the number of companies with Zero Trust plans has gone from 48% in 2020 to 94% in 2021. As a result, an increasing number of organizations are adopting Zero Trust Security as an element or a component of their network architecture and enterprise Security strategy.

Let’s have a look at what Zero Trust Security is and how to implement Zero Trust  Security in your organization to make your organization’s network more secure.

What is meant by Zero Trust Security?

Zero Trust Security is a framework for securing infrastructure and data required to address the challenges of today’s business network to authenticate, authorize, and continuously validate the security configuration of the organizations.

Zero Trust Security also uniquely addresses the modern challenges faced by organizations including securing remote workers, hybrid cloud environments, and also major cyber threats including ransomware.

Securing your network infrastructure and data for today’s modern digital transformation.

According to Zero Trust Security Strategy, organizations should not trust anything merely inside or outside its circumference. Instead, Zero Trust Security must verify anything and everything trying to connect to its systems before granting access to the IP addresses, machines, etc. until you know who that user is and whether they are authorized to your network or not.

What is Zero Trust Network Access(ZTNA)?

Zero Trust Network Access(ZTNA) is a technology with an IT security solution that provides secure remote access to an organization’s applications, data, and services based on clearly defined access control policies.

ZTNA differs from virtual private networks (VPNs) where ZTNA grants access only to a specific application, where VPNs grant access to an entire network. ZTNA serves as a private VPN for a private network.

Access to applications is restricted via a trusted broker to verify the identity, context, and policy adherence of the specified participants before allowing access. This significantly reduces the surface area for attack and exposure to cyber threats in an organization.

Principle of Zero Trust Security

The common expression for Zero Trust Security is “Never Trust, Always Verify”. Each access to the network resources by any users or devices must be authorized and encrypted based on the principle of least privilege.

In a  zero-trust network(ZTN), perimeters are defined around each of the company’s valuable assets through a micro-segmentation process where it is possible to enforce access controls to block the lateral movement of threats through the network and isolate a potential breach.

Multi-factor authentication (MFA) is one of the core values of Zero Trust security. It requires at least two forms of evidence to authenticate a user which is known as 2-factor authorization(2FA) that is usually used on online platforms like Facebook and Google.

Real-time monitoring via Zero Trust Security System minimizes the time between an initial breach and enables detection, investigation, and remediation, immediately closing the window of opportunity for attackers.

Benefits of Zero Trust Security

Implementing the Zero Trust Security System offers many benefits to any organization. The significant benefits mentioned below are what you get when you implement Zero Trust Security.

User Identification and Access

The Zero Trust Security system uses multi-factor authentication (MFA) to access resources that are more secure than two-factor authentication. By making it mandatory that only authorized users can access the resources.

Enhanced Data Protection

Zero Trust Security provides better protection against unauthorized access by employees or malware from gaining access to large portions of your network. If access to your network is restricted to only a limited dataset the Zero Trust Security reduces the impact of a breach.

Provides improved monitoring and alerting

Zero Trust Security systems resources use a combination of log and event analysis to identify when security issues occur and then provide insights into how to remediate them. This provides the administrators the ability to rapidly detect and respond to cybersecurity threats.

Secures Cloud adoption

Organizations using Zero Trust Security can adapt to remote work and cloud environments and have a greater security position. Zero Trust Security enables the classification of all assets on the cloud so that the right protections and access controls can be established.

Secure Your Remote Workforce

In recent years, one of the biggest challenges faced by IT organizations is the sudden shift to the remote working ecosystem. Zero Trust Security offers robust protection for workers and data in any location.

How to implement Zero Trust Security to your organization’s network:

Here are the steps on how to implement Zero Trust Security System in your organization.

Identity Verification

Firstly, monitor who needs to access your digital resources based on the identity of the humans and their devices, along with other conditions such as time, date, geolocation, etc. The attack surface is always expanding, making it difficult to define by determining your protected surface. 

The protected surface encompasses the critical data, application, assets, and services which are included in DaaS(Data as a Service) which is most valuable to enhance the security of your organization.

Do not allow or permit access to unauthorized entry to your digital resources present in your DaaS.

Segmentation

Zero Trust Security segments various subsets of resources such as data assets, servers, and applications to remove the ability for users to directly access the network without first going through a tightly controlled gateway. This is referred to as “network isolation.”

Microsegmentation takes this concept further by breaking up security perimeters into small zones to maintain separate access for separate parts of the network.

A person or program with access to one of those networks will not be able to access any of the other parts of the network without separate authorization.

Once you have implemented the Zero Trust Security identity-based segmentation method, move on to extend a zero-trust approach throughout your technology infrastructure.

Access Control

Zero Trust Security systems need to monitor whether users are only able to access the information and resources that are appropriate for their respective roles.

Role-based access control (RBAC) is a critical component of your access management. Only when you have a “definite” knowledge of who a user is, you will be able to grant   access to users/devices based on their role such as a user is an employee, guest, or contractor

Ensure each segment of the network is authorized to minimize the attack surface of the network.

Visibility

Zero Trust Security should continuously monitor, inspect and log all traffic to ensure that users are only accessing systems that they’re permitted to access.

This visibility is also applicable to cloud platforms or third-party networks from which our data is accessed. Zero Trust Security should also identify abnormal behaviors that could be malicious activity.

Conclusion

The best way to provide maximum security is to implement the Zero Trust Security systems in organizations, to ensure greater trust within the organization and add an additional security layer outside the organization.

Manier organizations are quickly adopting the Zero Trust Security System that makes more sense to verify users with an authentication rather than to merely trust their unauthorized entry into the network.

Having Zero Trust Security Systems in our organizations helps us to toughen the network defense system and provide stronger security for our data floating on our network.
