7 Small Business Network Security Best Practices

Whether you are just starting a small business or have been running one for years, taking the necessary steps to protect your network from potential threats is vital. 

Network security is an essential component of any successful business and there are several best practices that every small business should be aware of. 

In this article, we will discuss seven small business network security best practices that will help ensure the security of your data and systems.


Use Strong Passwords

Many people use the same password across multiple accounts, which can be a major security risk. 

If one account is hacked, all other accounts with the same password are also at risk. It is recommended that each account has a unique and complex password.


A strong password typically consists of at least 12 characters, including a mix of uppercase and lowercase letters, numbers, and special characters such as @ or !. 

Avoid using dictionary words or common phrases that hackers could easily guess. Using passphrases instead can make it easier to remember but harder to crack.


To create and manage strong passwords effectively, consider using a password manager tool that generates long and complex passwords while securely storing them for you. 

Additionally, enable two-factor authentication (2FA) whenever possible as an added layer of security beyond just your username and password combination. 

These simple tips can help protect your small business’s sensitive information from cybersecurity threats. 


Keep Software Up-to-Date

Regularly checking for software updates is one of the most important practices any business can do to keep its networks secure. 

It is essential to understand that outdated software poses a security risk, as new vulnerabilities and exploits are constantly being discovered by hackers. 

If left unpatched, attackers can exploit these vulnerabilities to gain unauthorized access or steal sensitive data.


To stay up-to-date with software updates and patches, businesses should immediately prioritize fixing critical security flaws when vendors release them. 

Businesses should also enable automatic updates and ensure their IT staff stays informed about any new updates available for their systems. 

Also, it is crucial to ensure that all devices connected to the network have the latest security patches installed.


Implement Firewalls

Having a firewall in place is crucial for small businesses that are looking to protect their network from cyber-attacks. 

A firewall acts as a barrier between your internal and external networks, controlling access to your system and monitoring incoming traffic. 

Blocking suspicious traffic can prevent unauthorized access, virus infections, or malware downloads.


When it comes to choosing and setting up a firewall, there are some tips that small business owners should keep in mind. 

Choosing a firewall solution that suits your specific needs and requirements is essential. This could be either software or hardware-based firewalls or a combination of both, depending on the organization’s size. 

Secondly, ensure that you configure the firewall correctly with appropriate settings, such as blocking all inbound traffic unless specifically authorized by an admin (default-deny rule). 

Lastly, regularly update firmware/software versions and maintain logs to identify threats.


Train Employees on Security Best Practices

It is not enough to simply have robust security measures in place. 

Employee training on security best practices is equally important to prevent data breaches and keep sensitive information safe. 


Practical employee training can be challenging for small businesses with limited resources or expertise. 

One tip is to create a comprehensive training program that covers all aspects of network security, including password management, email phishing attacks, social engineering scams, and malware prevention. 

Another tip is to use real-life examples and case studies to make the material more relatable and engaging for employees.


In addition, it’s important to make employee training an ongoing process rather than a one-time event. 

Regularly reminding employees about best practices and conducting refresher courses can help reinforce the importance of network security and reduce the likelihood of human error leading to a breach. 

Small businesses can better protect themselves against cyber threats and safeguard their customers’ personal information by prioritizing employee education on network security best practices. 


Use Encryption

Encrypting sensitive data is one of the most critical steps in securing a small business network.

Encryption refers to converting plain text into encoded text, which can only be read by authorized individuals who possess the decryption keys. 

This ensures that even if hackers gain unauthorized access to your network, they cannot easily read or steal sensitive information such as credit card numbers, passwords, and personal identification details.


To implement encryption on company devices and networks, it is recommended to use strong encryption algorithms such as Advanced Encryption Standard (AES) 256-bit encryption. 

It is also essential to ensure that all devices and applications used within the business are updated with the latest security patches and protocols. 

Additionally, businesses must educate their employees on adequately handling sensitive information, including encrypting files and emails.


Encryption is critical in protecting a small business network from cyber threats. 


Regularly Back Up Data

Having a backup plan in case of data loss or theft is essential for small businesses. 

Backing up data is important for network security because it ensures that sensitive information such as financial records, customer data, and business plans are not lost forever in case of cyber-attacks, natural disasters, or accidental deletion.


To back up data regularly, small businesses can use cloud-based services that automatically sync data to secure servers. 

Another option is to create regular manual backups on external hard drives and store them offsite. 

Small businesses should also consider using encryption software to protect confidential information.


Monitor Network Activity

Monitoring network activity is crucial to maintaining the security of any small business. 

It enables network administrators to detect suspicious behavior that could harm their organization. 

By monitoring network activity, administrators can quickly identify any unauthorized access or data breaches and take immediate action to prevent further damage. 

And responding quickly to any suspicious activity is critical in preventing data loss or theft.


One effective way of monitoring network activity is by using network monitoring tools. 

These tools are designed to provide real-time visibility into the activities happening within your organization’s network.

They can help you identify potential threats, such as malware infections or unauthorized access attempts before they cause significant damage. 

Setting up these tools requires a basic understanding of networking concepts and protocols.


When setting up network monitoring tools, configure them correctly so that they provide accurate and useful information about your network traffic. 

This involves determining which devices and applications on your networks need to be monitored, setting up alerts for suspicious activities, and configuring reports to analyze your network traffic patterns regularly. 


In conclusion, network security is one of the most critical aspects of running a small business. 

As more and more companies rely on technology for their daily operations, they become increasingly vulnerable to cyber attacks that can lead to data breaches and other types of security incidents. 

Small business owners must proactively protect their networks from these threats.


Several options are available if you’re looking for additional resources or the next steps to improve your network security. 

Consider working with a managed IT services provider specializing in cybersecurity, investing in training programs for your employees on recognizing and preventing cyber threats or implementing multi-factor authentication protocols across all devices.
