Impact of Implementing Zero Trust to Secure IT Infrastructure


Share post:

Zero trust network access is a critical component of any secure IT infrastructure. It enables organizations to reduce the risk of data loss, increase productivity and improve customer experience. Implementing a zero-trust network requires a significant investment of time and financial resources. It also involves the implementation of identity-based segmentation, limiting access to certain areas and ensuring access is defined by roles.

Reduced Risk of Data Loss

By limiting access to sensitive data or resources to those who need it, zero trust network access lowers the chance of data loss. By enforcing strict identity verification for every user and device, businesses can minimize the potential for security breaches caused by mistaken trust or even employee errors.

A crucial part of zero trust security is implementing network segmentation to isolate networks with business-sensitive data and applications. For example, if a hacker tries to access a company’s HR or finance data, they would be blocked from entering the public network. The data would remain locked away in another segment that only employees or authorized vendors can access.

In addition to limiting access to specific segments, zero trust also requires monitoring and logging all traffic passing through a network. It helps organizations understand how and when to change network policies based on a zero-trust policy rule, allowing them to enforce their network security effectively.

A critical step in implementing zero trust security is to ensure that all teams within the organization understand how it works. Whether it’s a storage team that manages all the locations where business data is stored, or a security team that protects the organization from hackers, all members should know what this change means and how they can support it.

Increased Security

zero trust network access model can increase security and privacy by eliminating the need for users to re-authenticate multiple times throughout the day. It also minimizes the risk of data loss. The security model is based on user identity, device trustworthiness, and security policies rather than the network from which access originates. Ultimately, it can help prevent insider attacks and breaches by limiting access to sensitive data.

Even small companies can adopt a zero-trust approach to protect their network from threats. However, before implementing this security strategy, it’s essential to understand how it works and how it can impact your business.

A zero-trust network must initially be able to watch and examine network activity. It also needs to be able to detect and identify potential threats, including insiders and third parties.

Another essential part of a zero-trust network is the ability to restrict access to critical resources, such as customer and employee data. By preventing users from accessing these assets outside of regular business hours, businesses can reduce the chances of being exposed to data theft and malware.

Implementing a zero-trust network is an ongoing process that needs to be implemented gradually and monitored regularly. It ensures that no significant changes or alterations are made that could leave gaps in the security of your network.

Increased Productivity

Zero trust network access can be a challenge to implement for businesses, as it requires a significant amount of time and resources. It also involves figuring out how to segment your network and define access to roles for specific areas of the network. A vital part of the process is ensuring that security management does not impact workflows or performance.

For example, if an employee changes their role and needs to be given updated access to data if they receive that information quickly, they could be allowed to do their job, which would help their productivity. Using zero trust to address these issues is critical.

This approach ensures that no one can access vital information without verifying their identity and only gaining the least-privilege access they need to complete their jobs.

To enforce a zero-trust network, companies must use micro-segmentation to isolate hosts and services that hold sensitive data from those that do not. It enables granular rules to be enforced, preventing hackers from lateral movement and containing breaches.

It can also increase the availability of your network since it eliminates the need for backhauling traffic through your main security controls. It can help to improve business agility and productivity, as well as reduce your overall costs.

Enhanced Customer Experience

Zero trust network access is a modern way of securing remote users and devices. It replaces legacy VPNs by enabling a cloud-first, software-based approach to ensure access. A successful zero-trust architecture requires consistent monitoring and evaluation of user behavior, data movements, and network changes.

It also requires a scalable infrastructure and an effective policy administration strategy to prevent breaches. Security policies are based on context—the user’s role and location, device, and the data they are requesting—to block inappropriate access and lateral movement throughout an environment.

A well-tuned zero-trust architecture leads to simpler network infrastructure, a better user experience, and improved cyber threat defense. In addition to limiting and monitoring access, a zero-trust strategy relies on strict user authentication. It is essential for employees.

Because humans are frequently the weakest link in any security approach, it’s necessary to have a robust authentication process. Organizations must segment their networks into smaller zones with separate security controls to maintain the zero-trust model.

These zones enable independent access to each part of the network based on data classification and different authentication methods. It is a complex, multi-phased process that must be transparent for all employees to understand. Failure to do so could lead to various security and user experience issues and hamper business growth.
