Network Security Tips for small businesses
Step 1: Use Strong and Unique Passwords
Over 60% of security incidents are linked to weak or reused passwords.
To boost password security:
- Choose a cost-effective password manager.
- Enable multi-factor authentication (MFA) using biometrics or security keys.
- Check new passwords against databases of compromised credentials.
Once you’ve established strong passwords, make sure to implement update protocols for continued protection.
Set Password Change Schedules
Creating strong passwords is just the start. To maintain security, you’ll need a smart approach to updates. Traditional 30-, 60-, or 90-day password rotation policies are now considered outdated. The Cybersecurity & Infrastructure Security Agency recommends avoiding mandatory periodic changes since they often lead to predictable, minor modifications.
Instead, use an event-driven approach for password updates:
- Security incidents: Reset passwords immediately after suspicious login attempts or unusual activity.
- Role changes: Update credentials when employees switch roles or leave the organization.
- Breach notifications: Change passwords right away if a data breach affects your accounts.
For high-level accounts, automated password rotation tools can help minimize risk. Research shows that employees reuse the same password an average of 13 times across different accounts, making automated tools even more critical.
Step 2: Install and Configure Firewalls
A firewall is one of the most critical defenses for protecting a small business network. It acts as a barrier between your internal systems and external threats. Setting up a firewall is a critical step in protecting your network from cyber threats, and pairing it with properly deployed business antivirus solutions creates a stronger, layered defense.
Choose the Right Type of Firewall
Choosing between different types of firewalls depends on your specific needs. Small businesses can benefit from several firewall options:
- Hardware firewalls: Physical devices placed between your network and the internet, ideal for protecting multiple systems at once.
- Software firewalls: Installed on individual computers or servers to provide device-level protection.
- Cloud-based firewalls: Managed online and scalable, suitable for businesses using cloud services or remote teams.
Selecting the right option depends on your network size, budget, and security needs.
For many small businesses, combining both types works well. A hardware firewall can safeguard the entire network, while software firewalls add an extra layer of protection to individual devices.
Basic Firewall Setup Steps
Follow these steps to configure your firewall effectively:
- Initial Security Configuration
Start by updating the firmware, disabling default accounts, setting strong admin passwords, and enabling automatic updates. - Network Zone Configuration
Define separate zones for different purposes, such as public-facing services, internal applications, guest access, and administrative functions. This segmentation helps control access. - Access Control Implementation
Set firewall rules to allow only approved IP addresses, ports, and protocols. Include authentication levels where needed. Document changes, audit configurations regularly, and enable logging with automatic alerts for suspicious activity.
To maintain security, back up your firewall settings, review logs often, and test updates in a safe environment. Consider integrating a SIEM tool to analyze logs and detect potential threats.
Step 3: Set Up VPN Access
A virtual private network (VPN) is essential for protecting business data, especially with the rise in remote work. With 43% of cyber attacks targeting small businesses, a VPN creates a secure, encrypted tunnel between your devices and the internet, making sensitive data much harder to intercept.
Why Small Businesses Need VPNs
Here’s how a VPN can benefit your business:
- Data Protection: Encrypts sensitive information during online activity
- Remote Access: Allows employees to securely connect to company systems from anywhere
- Compliance: Supports adherence to regulations like HIPAA
- Low Overhead: Eliminates the need for physical infrastructure
- Device Compatibility: Works across multiple devices with a single account
Research shows that 80% of users rely on VPNs for security, and half use them on public Wi-Fi. Like firewalls, a VPN is an important part of a layered security approach.
With these advantages, it’s worth exploring providers to find one that fits your needs.
Choose a reliable VPN Service
To select the right VPN, look for a provider that offers strong features within your budget:

- Rates of incident reporting
- Compliance with security policies
Tailor training to specific roles. For example, accounting teams should focus on preventing financial fraud, while sales teams need to prioritize protecting client data. By addressing these unique needs, you can strengthen your overall security posture while reducing human error.
Step 6: Set Up Data Backups
Losing data can seriously disrupt a small business. Having reliable backups in place ensures your operations can continue smoothly, and professional data recovery support can further reduce downtime.
The 3-2-1 Backup Method
The 3-2-1 rule is a simple and effective way to protect your data:
| Backup Component | Implementation | Best Practice |
|---|---|---|
| 3 Copies | Original data + 2 backups | Keep daily backups of critical files |
| 2 Different Media | Use multiple storage types | Combine local drives with cloud storage |
| 1 Offsite Copy | Store one copy in a remote location | Use cloud services or an offsite facility |
For instance, a retail business might:
- Back up daily to an external hard drive
- Sync data automatically to Microsoft Azure cloud storage
- Keep weekly backups on a separate drive stored offsite
Once your backup strategy is in place, evaluate your options to ensure the best fit for your business.
Cloud vs. Local Backup Options
Here’s a quick comparison of cloud and local backups:
| Feature | Cloud Backup | Local Backup |
|---|---|---|
| Cost Structure | Monthly subscription | One-time hardware investment |
| Recovery Speed | Depends on internet speed | Faster, since it’s local |
| Scalability | Virtually unlimited | Limited by hardware capacity |
| Remote Access | Accessible from anywhere | Limited to physical location |
| Security Control | Managed by the provider | Fully controlled by you |
A hybrid approach often works best. For example, you can store sensitive data locally to meet compliance requirements while backing up operational files to the cloud for easy access. Automate daily backups for both systems to save time and reduce risks.
Plan your backup schedule based on the type of data:
- Daily: Critical files
- Weekly: System configurations
- Monthly: Full system images
This ensures you’re prepared for anything, from small hiccups to major disruptions.
Step 7: Lock Down Wi-Fi Networks
Securing your Wi-Fi network is a crucial step in protecting your business from potential cyberattacks. Hackers often target Wi-Fi networks to gain unauthorized access, so taking precautions is non-negotiable.

Start by accessing your router’s administration panel, either through its IP address or the manufacturer’s app.
| Setting | Recommended Configuration | Why It Matters |
|---|---|---|
| Admin Password | Use a strong, unique password | Blocks unauthorized access to your router |
| Network Name (SSID) | Choose a custom, non-identifiable name | Makes your network less of a target |
| Guest Network | Set up a separate network with limited access | Keeps visitor traffic isolated from your main network |
| Remote Management | Turn it off | Prevents external configuration attempts |
| Firmware | Keep it updated | Fixes known security vulnerabilities |
“Manufacturers appreciate the importance of router security and reliability more than ever, so the products are much more user‐friendly than they used to be. They now handle a lot of the key security settings for you”.
Here are a few actions to further secure your router:
- Change default credentials by using tools like www.routerpasswords.com.
- Enable the router’s firewall for extra protection.
- Turn off Wi-Fi Protected Setup (WPS), as it’s prone to vulnerabilities.
- Regularly check connected devices through the admin interface to spot and block unauthorized users.
Once your router is secure, it’s time to move to WPA3 encryption for even better protection.
Set Up WPA3 Security
Since July 1, 2020, all new Wi-Fi CERTIFIED devices are required to support WPA3.
| Feature | WPA2 | WPA3 |
|---|---|---|
| Password Protection | Shared encryption key | Individual encryption for each device |
| Offline Attack Defense | Vulnerable to multiple guesses | Limits attackers to one guess per attempt |
| Forward Secrecy | No | Yes – generates a unique key for every session |
| Open Network Security | None | Encrypts traffic even on open networks |
If your hardware is older, make sure you’re at least using WPA2-PSK with AES encryption. When upgrading, look for the Wi-Fi CERTIFIED label to ensure WPA3 compatibility.
To get the most out of WPA3:
