4 Steps To Build A Resilient Network Infrastructure

April 14, 2023 No Comments

by Jack Donovan

Network infrastructure is the backbone of any organization’s IT system. It supports device communication and enables employees to access critical data and applications. However, building a resilient network infrastructure requires much effort and planning.

A robust network infrastructure is imperative for seamlessly executing an organization’s day-to-day activities in today’s constantly evolving business environment. With it, businesses may avoid network outages, which can cause significant losses in revenue and productivity. 

Fortunately, managed IT services, such as IT services in Denver, offer a comprehensive range of network infrastructure solutions to help organizations achieve their desired level of resiliency.

If you’re considering where to start when building a resilient network infrastructure as a business owner, read further to learn the essential steps.

1. Conduct A Network Assessment

You must first understand your existing network infrastructure to build a resilient one. This step entails closely examining your network components, devices, and software to pinpoint areas that require improvement. 

Conducting a network assessment can provide insight into your network’s current state and what actions are necessary to enhance its resiliency.

The initial step in conducting a network assessment is identifying potential weak points. It involves scrutinizing various network aspects like hardware, software, security, and bandwidth to determine potential areas of concern. 

For instance, outdated hardware or software can cause network disruptions, while insufficient bandwidth can result in sluggish network performance.

Once you’ve identified potential weak points, the subsequent step is to conduct a risk analysis. This step involves evaluating the probability and impact of each possible failure and ranking them based on severity.

2. Develop A Network Architecture Plan

Another essential strategy is developing a network architecture plan that suits your business needs. A network architecture plan is a blueprint that outlines the structure, design, and components of your network infrastructure. 

Consider your organization’s objectives, requirements, and budget while providing a framework for building a robust and resilient network.

The appropriate network components and technology are crucial when creating a network architecture plan. This step involves choosing the proper hardware, software, and networking protocols to meet your business requirements. By selecting the right components, you can guarantee that your network infrastructure is dependable, scalable, and capable of supporting your business’s growth.

Another critical element is devising a redundancy plan to reduce downtime. Redundancy involves having multiple systems or components in place to ensure another can take over smoothly if one fails. You can achieve this by implementing backup power supplies, redundant network links, and redundant storage systems.

3. Implement Network Security Measures

Ensuring your networks and data are protected against security threats to prevent unauthorized access and fend off malicious attacks is crucial to building a resilient network infrastructure.

It’s essential to establish security policies and protocols with meticulous attention to ensure the confidentiality, integrity, and accessibility of your data. It requires identifying the individuals who may enter your network, the particular data they’re permitted to retrieve, and the method by which they can enter. 

Additionally, it’d best to create a framework for addressing security incidents and safeguarding your network against internal and external threats.

Furthermore, security technologies, such as firewalls and intrusion detection and prevention systems, can efficiently strengthen your network’s defenses. Firewalls, for instance, enable you to regulate access to your network, thwarting any unsanctioned attempts at entry. 

Meanwhile, intrusion detection and prevention systems can instantly identify and obstruct malicious attacks. Implementing these technologies can significantly reduce the dangers and susceptibilities of your network infrastructure.

Regularly conducting security audits and assessments is essential in identifying and addressing network vulnerabilities before attackers exploit them. Conduct these audits regularly to ensure your network infrastructure’s continued security and resilience.

4. Implement Disaster Recovery And Business Continuity Plans

Building a robust network infrastructure requires the implementation of disaster recovery and business continuity plans. These plans are crucial in guaranteeing the smooth running of your business and quick recovery from unexpected occurrences, such as cyber-attacks, hardware failures, or natural disasters.

A disaster recovery plan contains a set of guidelines that can restore network operations in the event of a catastrophic occurrence. This plan should incorporate data backup and storage procedures, recovery processes, and a strategy for restoring critical systems and applications.

Similarly, a business continuity plan ensures uninterrupted business operations before and after an unexpected event. It should contain procedures for relocating your processes, creating communication channels, and identifying crucial business functions that require priority.

With that in mind, testing and updating disaster recovery and business continuity plans is imperative to ensure their efficiency. You can conduct frequent simulations and tests to identify plan gaps and make the necessary updates.


Building a resilient network infrastructure is essential for any business that relies on technology. A resilient network infrastructure can help you avoid downtime, protect data, and ensure uninterrupted business operations.
