Ask five businesses in Midland what their IT infrastructure and security looks like and you’ll get five different answers. Some have a managed firewall and a documented network. Some have the router the internet provider left behind. Many aren’t sure.
This checklist covers the baseline every business should have, whatever its size or industry. Use it to check your own setup. If you can’t answer an item, count it as a no.
Quick Answers
What is IT infrastructure and security?
Infrastructure is the equipment and services your business runs on: network, internet, computers, servers, and cloud accounts. Security is the set of controls that keeps them running and protects the data on them.
What is the most important security control for a small business?
Multifactor authentication (MFA) is one of the most effective, because it blocks most attacks that rely on a stolen password.
The 18-Item Checklist
1.Network and Internet
- A business-grade firewall that is updated and monitored, not the default router from your internet provider.
- Guest Wi-Fi kept separate from the network your business systems use.
- A second internet connection if your business can’t work offline.
2. Computers and Devices
- Endpoint protection on every computer, with endpoint detection and response (EDR) on anything that holds sensitive data.
- Automatic operating system and software updates, with someone confirming they installed.
- Mobile device management for phones and tablets that access company email or files.
3. Accounts and Access
- Multifactor authentication on email, remote access, and admin accounts. Microsoft reports that accounts using MFA are more than 99.9% less likely to be compromised.
- Separate admin accounts, not everyday logins with admin rights.
- Accounts turned off the same day an employee leaves.
4. Data and Backups
- Automatic backups of servers, computers, and cloud data such as Microsoft 365.
- At least one backup copy kept offline or isolated from your network.
- Restores tested on a schedule. CISA’s guidance for small businesses notes that many ransomware victims had no backups or damaged ones.
5. People
- Phishing awareness training for everyone with a company email account.
- Dark Web monitoring for company email addresses and passwords.
- A written plan for who to call and what to do if something goes wrong.
6. Physical Infrastructure
- Organized, labeled network cabling.
- Battery backup and surge protection on servers, firewalls, and switches.
- A locked, ventilated space for network equipment. Midland summers make ventilation matter.
How Did You Score?
| Items in place | What it means |
| 16 to 18 | A solid baseline. Keep it maintained and reviewed. |
| 10 to 15 | Common gaps, usually in backups, access, or documentation. Fix the account and backup items first. |
| Under 10 | High risk of an outage or breach. Start with MFA, automatic updates, and tested backups. |
Why Layers Matter More Than Any Single Tool
No single product covers everything. A firewall doesn’t stop a phished password. MFA doesn’t restore a deleted file. Each layer covers gaps in the others. For a closer look at how the layers fit together, see what a modern cybersecurity stack looks like.
If you are filling out a cyber insurance application, expect most of these items to appear on it. We covered typical cyber insurance requirements separately.
Getting the Baseline in Place
Most businesses don’t need to replace what they have. They need someone to check it against a list like this, fix the gaps in order, and keep it maintained. Our IT infrastructure and security services cover network security, cloud backups, mobile device management, connectivity, and cabling. Under managed IT services, a Technology Alignment Manager reviews your environment on a regular schedule so the baseline keeps up as your business changes.

AI Overview
Every business in Midland should have a baseline of IT infrastructure and security across six layers: a managed firewall and separate guest Wi-Fi; endpoint protection and automatic updates on every device; multifactor authentication and prompt account removal; automatic, isolated, and tested backups; phishing training and Dark Web monitoring for staff; and organized cabling with battery backup for network equipment. Layers matter because no single tool covers every risk. Businesses below the baseline should start with MFA, updates, and tested backups.
Key Takeaways
- Check your setup across six layers: network, devices, accounts, data, people, and physical.
- If you can’t answer a checklist item, count it as a no.
- MFA, automatic updates, and tested backups come first.
- No single tool covers every risk. Layers cover each other’s gaps.
- Review the checklist whenever your business changes.
Frequently Asked Questions (FAQ)
What does IT infrastructure include?
Your network, internet connection, firewall, Wi-Fi, computers, servers, phones, cloud services such as Microsoft 365, and the cabling and power equipment they depend on.
How often should a business review its IT security?
At least once a year, and whenever something changes: new staff, a new location, new software, or a new insurance application.
Does a small business need a business-grade firewall?
Yes. The default router from an internet provider is not built to be monitored, updated, and configured for business security. A managed firewall is the first layer between your network and the internet.
Will this checklist help with cyber insurance?
Most of these items, including MFA, endpoint protection, tested backups, and security training, appear on cyber insurance applications. Having them in place and documented makes the application easier to complete accurately.
