Your complete network audit checklist: 7 things you should include

Reports show that security and network breaches account for at least 8+ hours’ downtime per incident. This can be catastrophic for small and medium-sized businesses.

You certainly can’t stop every possible threat from affecting your network. But there are many steps you can take to protect your infrastructure and your confidential business information from cybercrime. It all begins with a network audit.

What is a network audit?

The network audit tells you how healthy your network is. It shows you if there are any weaknesses in the network that leave you vulnerable to cybercrime and system downtime. Audits are commonly performed by managed IT service providers for the most comprehensive and reliable results.

But there are steps you can take yourself to check your own network’s health.

What the network audit looks for

Put simply, the network audit compares your existing network performance against a predetermined “ideal” network standard. You’re looking to see if your network falls short of your expectations of its performance and security strength.

Namely, then, you’re checking things like:

  • Routers
  • Servers
  • Firewalls
  • End devices
  • Switches

You should audit your network frequently as standard. But there are a few occasions when you should definitely audit your existing network architecture:

  • The network is slow or crashes frequently
  • You’re planning a system upgrade, or you’re adding numerous devices to the network
  • You want to find inefficiencies in your network and improve its overall performance
  • New regulations come into force which your organization must comply with

It is true that a network audit is mainly about drawing comparisons between what the network currently looks like and how you need it to look. But you still need to know how to perform it properly. That’s where a checklist comes in. 

The stages to a great network audit – design your checklist

With a network audit checklist, you can quickly perform your audit and lay the results out clearly. If you don’t already have a checklist template, or you’re unsure how comprehensive it is, here’s what the audit should include.

Number 1

Your network cybersecurity vulnerabilities

Chances are, your network is more vulnerable to cyberattack than you realize. Cybercrime is extremely lucrative, with monetary gain motivating nearly 3/4 of cyberattacks, and AI replacing the need for human involvement in the phishing process.

Your audit should assess:

  • Connected devices
  • Passwords
  • Third-party application access
  • Patches
  • Whether external devices, such as employee remote devices, can access your main WiFi network, or if they can only access a separate “public” WiFi



Number 2

Network bandwidth demands and challenges

Any network only has a finite amount of bandwidth it distributes among connected users. Unless you know how your network distributes this bandwidth, you can’t assess whether you need more or less bandwidth to handle business needs.

Check your overall bandwidth usage and look for any slow points throughout the system. See if any users, or any hardware, consume more bandwidth than others.

Number 3

Data and file security

How you collect, store, process, and distribute data is incredibly important. When you’re assessing data and file security, check for:

  • Password protections
  • Access rights
  • Whether users can edit or otherwise modify files containing sensitive information
  • Encryption strength
  • The anti-malware and security software you’re using, and whether it needs updating
Number 4

Your BYOD policy

If you let your employees bring their own devices – including cell phones – to work, which most organizations do, these devices bring unique security and bandwidth problems. What you should have is an effective BYOD policy.

Check the following:

  • If there’s any BYOD policy in operation
  • If employees know how to safely connect their own device to the network
  • How these external devices interact with the business network
  • Whether you need network monitoring software to constantly monitor the effects of external devices connecting to the network
Number 5

Any existing weaknesses in the network infrastructure

Your network infrastructure includes:

  • Operating systems
  • Firewalls
  • Software and other applications
  • Hardware
  • Access points
  • Cables, switches, and other relevant accessories

It doesn’t usually include personal devices or servers.

The best way to assess your network infrastructure, or architecture, is by designing a network map. This highlights problems such as forgotten firewalls and other inefficiencies.

For the best results, consult an IT professional for mapping techniques.

Number 6

If any upgrades are needed

Upgrades are often necessary when it’s time to bring in more hardware or update outdated software. You should be looking for whether you need:

  • Software patches
  • An improved automatic or manual software updating procedure
  • Increased firewall protection
  • New cables or other hardware to accommodate higher-tech equipment or additions to your network

When you’re a growing business, scaling your network to suit business needs is only possible with a proper network auditing technique.

Number 7

Future steps and outcomes

Once you’ve completed your audit, it’s important to assess your findings. Remember, the audit is only part of your overall cybersecurity management plan – don’t simply check off boxes on your list and forget about the results.

Perhaps you’ve identified hardware that needs upgrading, or maybe your employees need additional training on the BYOD policy. Whatever issues the audit raises, discuss these issues promptly so you can decide on an action plan moving forward.

If you aren’t sure how to action the results of your audit or improve the results for next time, it might be best to ask an IT services provider for help.

As cyber hackers become more sophisticated and threats evolve all the time, network security is more important than ever. While it’s impossible to prepare for every eventuality, with the right network audit checklist, you can mitigate the risk of cyber threats affecting your business.
