Small Business Cybersecurity Checklist: How to Know Your Business Is Secure

Having cybersecurity measures in place is critical for protecting your business. Especially for small businesses, where a cyberattack can disrupt operations even more and create significant financial losses. But simply having a few security measures is not enough. The bigger question is whether your current cybersecurity plans actually protect your business’s systems and data effectively.

So how do you know that your business is properly secure?

Why Cybersecurity Is Important

Cybersecurity protects computers, networks, applications, data, and other digital assets from theft, disruption, unauthorized access, and other cybersecurity threats. Even small businesses have important information that needs to be protected. If online data and networks are unprotected and compromised, it could result in financial losses, reputation damages, and downtime.

Cybersecurity helps protect businesses from these threats by protecting sensitive data and information. Strong cybersecurity doesn’t just respond to cyber attacks. It should reduce the risk of data breaches, control who can access systems, detect suspicious activity, and resort operations.

Cybersecurity Best Practices for Small Businesses

So what should small businesses look for when checking if their business is secure? This small business cybersecurity checklist can help you review your current security position and identify areas that may need more attention:

Access Control

• Enable Multi-Factor Authentication
  • Use multi-factor authentication wherever possible, especially for:
    • Email accounts
    • Financial systems
    • Cloud software
    • Remote access tools
    • Administrative accounts
  • Authentication apps and hardware security keys generally provide stronger protection than SMS alone.
• Require Strong, Unique Passwords
  • Require strong, unique passwords for important systems and accounts.
  • Using a business password manager can also help employees create, store, and securely share credentials without relying on reused or easily guessed passwords.
• Limit Administrative Access
  • Only give administrative privileges to employees who need them.
  • Make sure to review permissions regularly, and remove or update access immediately when employees leave the company or change roles.

Software and Network Security

• Automate Software Updates
  • Keep operating systems, browsers, applications, routers, and other devices updated with the latest security patches.
  • Enabling automatic software updates where appropriate can reduce exposure to known vulnerabilities.

• Protect Endpoints
  • Use reputable antivirus software or endpoint protection tools on devices that access company systems.
  • For businesses with more advanced cybersecurity needs, endpoint detection and response tools can provide additional monitoring and protection against suspicious activity.
• Secure Your Business Network
  • Protect your Wi-Fi and network infrastructure by:
    • Changing default router and administrator passwords
    • Using WPA3 or WPA2 encryption
    • Keeping router and firewall firmware updated
    • Separating guest devices from the primary business network
    • Blocking unauthorized devices when appropriate

Data Protection

• Encrypt Sensitive Data
  • Sensitive data should be encrypted both at rest and in transit.
  • This is especially important for customer information, employee records, financial data, and other confidential business information.
• Back Up Important Data
  • Automate regular backups of critical systems and files.
  • Backups should be stored separately from the live network so ransomware attacks or other cyber threats cannot easily compromise both the original data and its backup.
• Test Your Backups
  • Do not assume a backup works simply because it exists.
  • Test restores regularly to confirm that important information can be recovered successfully when needed.

Employee Training and Security Policies

• Provide Security Awareness Training
  • Employees are often targeted through phishing emails, fake login pages, malicious links, and other social engineering tactics.
  • Regular security awareness training can help employees identify suspicious activity before it becomes a larger problem. Phishing simulations can also help reinforce what employees learn.
• Create an Incident Response Plan
  • Every business should have a basic incident response plan.
  • Document:
    • Who employees should contact
    • What actions should be taken
    • How affected systems should be isolated
    • How customers or partners should be notified when required
    • How operations will be restored
• Employees should also understand their responsibilities during a cybersecurity incident.

Choose the Right Cybersecurity Provider

For many small businesses, maintaining the right level of cyber security requires outside expertise. When evaluating a provider, look for more than basic technical support.

• Compliance
  • Your provider should understand and meet the data protection regulations and industry requirements that apply to your business.
• Protection and Prevention
  • Look for proactive protection of devices, networks, applications, and sensitive information, including patch management and vulnerability reduction.
• Access Control
  • The provider should support multi-factor authentication, secure account management, and proper access controls.
• Detection
  • Continuous monitoring can help identify cybersecurity threats and suspicious activity before they cause greater damage.
• Response and Recovery
  • Your provider should have a clear process for containing incidents, recovering affected systems, and restoring normal business operations.

Protecting Your Business Starts With Knowing Where You Stand

Cybersecurity is not a one-time setup. As your business grows, your systems, employees, and security risks change. Reviewing your cybersecurity plans regularly can help identify security gaps before they lead to a data breach. Strong cybersecurity practices should protect sensitive information, reduce risk, and make it easier to recover if and when problems occur.
