IT Infrastructure Audit: Checklist, Network & System Assessment

The business’s IT systems are not merely the support function but the backbone of the business’s routine operations. Every aspect of the business today depends on a well-functioning IT ecosystem, whether it is managing customer data, team collaboration, or anything else. Still, most businesses pay attention to IT only when something breaks and not otherwise. 

This is where the IT infrastructure audit plays a crucial role and helps businesses avoid chaos. It is due to the rising cyberthreats, downtime, and technology that IT infrastructure audit has become key for businesses. This is what helps businesses to uncover vulnerabilities, optimize performance, and align their IT with the business goals.

But before that, it is crucial to understand how to conduct a proper IT infrastructure audit to get the desired outcome. This blog discusses in depth how to audit the business IT infrastructure to leverage it for your business. 

IT Infrastructure Audit

It is a process by which businesses come to know about their IT infrastructure, such as whether everything is working properly or not, before it turns severe. In this, businesses review everything like hardware, software, networks, security systems, and processes. 

The businesses can get answers to the critical questions with the IT infrastructure audit, which includes the following. 

• Are your systems secure from cyber threats?
• Is your network optimized for performance?
• Are you overpaying for unused resources?
• Can your infrastructure scale with your growth?

Also, most businesses confuse the terms IT audit, network audit, and IT system assessment. All these are different. An IT audit is an evaluation of a business’s policies, governance, and compliance, a network audit focuses on network performance, connectivity, and security, and an IT system assessment checks the effectiveness and efficiency of your systems. 

Why Business Needs to Do an IT Infrastructure Audit?

Admit it or not, but most businesses wait for their IT systems to break and then do an IT infrastructure audit, which causes harm. Instead, it is crucial to do an audit beforehand to help you stay ahead. Here are the reasons businesses need to get the audit done. 

Identify the inefficiencies 

Most businesses continue to keep working with outdated hardware, redundant software, or underutilized cloud services. But the reality is that these are nothing but the inefficiencies hidden in your business. This makes it vital to get the audit done to identify these, as they do not add value and simply drain your budget. 

Strengthens cybersecurity 

The next reason businesses need an IT infrastructure audit is that it strengthens the cybersecurity posture. The businesses might not realize this, but even small vulnerabilities can lead to significant losses due to ransomware and data breaches. But what happens is that businesses can conduct the audit to know about the gaps in firewalls, access controls, and endpoint protection.

Improves performance 

The IT infrastructure audit also improves performance. The slow systems, lagging networks, and frequent downtime hamper the business’s performance, reduce the overall productivity, and lead to poor customer experience. The only alternative to this is to conduct an IT infrastructure audit to optimize your IT infrastructure.  

Compliance with regulations 

Another reason to get the IT infrastructure audit done is compliance with regulations. Businesses must ensure compliance if they come from a regulated industry, and also to reduce the legal risks that result in informed decisions about the upgrades, investments, and scaling.

When to Get an IT Infrastructure Audit? 

Most businesses are unsure whether they need an IT infrastructure audit for their business, or not, which costs them downtime, security breaches, and operational inefficiencies. This results in the delay and turns the issues severe. But not anymore. 

Here are the key signs to take note of that indicate it’s time for you to get an IT infrastructure audit done. 

Frequent Downtime and System Slowdowns

The frequent downtime and system slowdowns are the foremost and most significant signs you need to take note of. This is a major red flag and happens due to overloaded servers, outdated hardware, or poorly configured systems.

You never know when the minor slowdowns turn into severe productivity losses. This makes employees spend more time on the tasks, which in turn impacts the efficiency and output. This requires a detailed audit to ensure that the systems are optimized. 

Cybersecurity incidents 

The next sign to take note of is the cybersecurity incidents. Most businesses think that phishing attempts, malware infections, or unauthorized access are normal. But the reality? These indicate deeper vulnerabilities within your IT environment.

The cyberthreats keep on evolving. This means that if a business still relies on outdated security measures, then they make their business prone to attacks. The only alternative to this is to get the audit. 

The audit evaluates your firewalls, endpoint protection, access controls, and patch management processes to let you know the gaps that can turn severe anytime and can lead to a breach happening. 

Outdated Hardware and Software

The outdated hardware and software are another notable sign for businesses to take note of. Businesses think it is safe to rely on the outdated systems, but in reality, these can hinder their operations. These might not support modern applications. Also, the unsupported software lacks critical security updates. 

All this does not just hamper the performance but also increases the risk of cyberattacks. With an audit, the businesses can identify the upgrades which ensures your technology stays secure. 

Lack of Visibility and Documentation

The next comes the lack of visibility and documentation. Its infrastructure management sounds challenging to most businesses because they have no clear record of IT assets, licenses, and configurations. 

This then results in troubleshooting issues, planning an upgrade, or ensuring compliance, as there’s no proper documentation. This requires an IT audit checklist to ensure everything in your IT Infrastructure is documented and organized well to make it easy to manage.

Rising IT costs 

If your IT costs are high but are not bringing any return on investment, then this also indicates the need to conduct an audit. This shows that your resources are not being used properly. The rising costs would mean paying more for the unused software licenses, redundant tools, or inefficient cloud services.

But you can reduce your IT costs with the IT system assessment. The assessment brings you a flexible and scalable infrastructure that adapts to the changing needs of your business without any disruptions. 

Compliance concerns 

Another significant sign is compliance. This is especially for the businesses in the regulated industries like healthcare, real estate, finance, and others. If these industries fail to meet the compliance, then this can result in penalties and reputational damage.

This indicates gaps in your IT policies and systems. You can fix this with an infrastructure review to ensure that the systems meet the regulatory requirements and that the practices are secure. 

Step-by-Step Process to do an IT Infrastructure Audit 

The IT infrastructure audit is not to be done randomly but strategically. Businesses must follow a proper process for doing an audit. Have a look at the detailed IT infrastructure audit checklist to get started with the audit. 

Asset Inventory and Documentation

The asset inventory and documentation are the first steps businesses need to take to create a comprehensive inventory of all their IT assets. The IT assets include servers, desktops, laptops, networking devices, software applications, and cloud resources.

Then you need to have the complete details of your documents, which include the following documents. 

• Device specifications
• Software versions
• Licensing information
• Warranty and lifecycle status

Doing so gives visibility to businesses and helps them identify the outdated assets. Otherwise, it becomes guesswork for the businesses to manage the IT systems without the proper documentation. 

Network Audit and Performance Review

The next step is the network audit and performance review. A network audit is crucial as it tells a business whether its network supports the routine operations or not. Here are the things businesses need to assess during the network audit. 

• Routers, switches, and firewalls configuration. 
• Bandwidth usage and internet speed.
• Network segmentation and security.
• Coverage and reliability of wifi.

You need to look into the bottlenecks, latency issues, and potential security gaps in your network. Otherwise, a poorly configured network risks slowing down your entire business and making you prone to cyber threats. 

Security Assessment

Security is the most important in IT infrastructure. The security assessment must cover the following things. 

• Patch management and updates
• Antivirus & endpoint protection
• Intrusion detection systems
• Firewall settings
• User access controls
• Authentication methods

Besides this, the businesses also need to conduct vulnerability scans to identify weaknesses so that the sensitive data is encrypted and only the authorized users have access to the data. 

Backup and Disaster Recovery Review

The backup and disaster recovery review is the next essential step in an IT infrastructure review. Today, every business runs on data, meaning that the entire business can halt if it loses its data. This makes it vital to review the backup and disaster recovery. 

In this, the businesses need to evaluate the number of times the backup takes place, storage locations of the backup, recovery time goals, and planning and testing of the disaster recovery. The backups must be automated, secure, and regularly tested to minimize downtime and ensure business continuity.

Software and System Evaluation

Your software system should be such that it supports efficiency and not hinder it. When conducting the software and system evaluation, the businesses need to assess operating systems and application performance, compatibility between tools, and software updates and patching. 

This is because the outdated software can result in security risks or performance issues. This comes under the IT system assessment and ensures that the tools you use are reliable and up-to-date. 

Compliance and Regulatory Check

Then comes the compliance and regulatory check. The businesses that come from the regulated industry, such as healthcare, finance, and others, need to comply with industry regulations and standards like HIPAA, PCI, and others. 

Without this, the businesses make themselves prone to the heavy penalties and ruin their reputation in the market. An IT infrastructure audit ensures your systems meet the regulatory requirements. 

Cloud Infrastructure Review

The dependency on cloud services is real, which makes it vital to review the cloud environment. You need to evaluate how resources are being utilized, security configurations, and cost optimization during the cloud infrastructure review. 

This saves you from unnecessary expenses and can also improve the scalability and performance in the long run.
