Quick Cybersecurity Wins for SMBs: 10 Easy Tweaks

Last Updated on February 24, 2025

Cybersecurity can be challenging for small and medium-sized businesses (SMBs). With limited budgets, fewer IT resources, and increasing threats, it’s easy to feel overwhelmed. However, keeping your business safe doesn’t have to involve expensive tools or complex strategies. Implementing a few simple, high-impact security tweaks can significantly reduce your risk of falling victim to cyberattacks.

This guide provides a detailed roadmap for SMBs to improve their cybersecurity posture with practical, easy-to-implement solutions. These “quick wins” are designed to offer maximum protection with minimal effort and cost.

Key Takeaways:

---

1. Enable Automatic Updates

One of the simplest and most effective ways to protect your business is by keeping all software up to date. Cybercriminals often exploit known vulnerabilities in outdated software to gain access to systems. Automatic updates ensure that you’re always running the latest versions of your operating system, applications, and firmware, which include critical security patches.

How to Implement:

• Operating Systems: Enable automatic updates for Windows, macOS, or Linux. For example, Windows Update can be configured to install patches during off-hours to avoid disruptions.
• Applications: Regularly update business-critical software like Microsoft Office, Adobe Acrobat, and web browsers such as Chrome or Firefox.
• Firmware: Don’t forget hardware like routers and printers—check with manufacturers for firmware updates.

Pro Tip:

Use centralized patch management tools if you have multiple devices in your organization. This ensures consistent updates across all endpoints.

2. Use Strong, Unique Passwords

Weak or reused passwords are one of the most common ways hackers gain access to accounts. A strong password policy is essential for protecting your business systems and data.

Best Practices:

• Length and Complexity: Require passwords that are at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special characters.
• Avoid Reuse: Each account should have its own unique password. Reusing passwords across platforms increases vulnerability if one account is compromised.
• Password Managers: Tools like Proton Pass or Bitwarden can generate strong passwords and store them securely so employees don’t have to remember them all.

Pro Tip:

Consider implementing passphrases instead of traditional passwords. For example, “Fridays$Are@Great123” is easier to remember but still highly secure.

3. Turn On Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA) adds an extra layer of security by requiring a second form of verification beyond just a password. Even if an attacker steals a password, they won’t be able to access the account without the second factor.

How It Works:

MFA typically involves something you know (a password) and something you have (a code sent to your phone or generated by an app). Some advanced systems also include biometric verification like fingerprints or facial recognition.

Where to Enable MFA:

• Email accounts (e.g., Gmail or Microsoft 365).
• Cloud storage services (e.g., Dropbox or Google Drive).
• Financial platforms like online banking or accounting software (e.g., QuickBooks).

Pro Tip:

Use authenticator apps like Google Authenticator or Microsoft Authenticator instead of SMS-based codes for better security against SIM-swapping attacks.

4. Secure Your Wi-Fi Network

Your business’s Wi-Fi network is a critical entry point that hackers can exploit if it’s not properly secured. A compromised network can lead to data breaches or malware infections.

Steps to Secure Wi-Fi:

1. Encryption: Use WPA3 encryption for the highest level of security; if unavailable, WPA2 is the minimum standard you should use.
2. Change Default Settings: Update default router usernames and passwords immediately after installation—these are often publicly available online for specific models.
3. Guest Networks: Create a separate guest network for visitors or clients so they don’t have access to your main business network.

Pro Tip:

Disable SSID broadcasting for your main network so it doesn’t appear in public Wi-Fi lists, making it harder for unauthorized users to find.

---

5. Limit Administrator Privileges

Not every employee needs administrative access to your systems. Limiting admin privileges reduces the risk of accidental changes or malware spreading through elevated permissions.

How to Implement:

• Assign standard user accounts for daily tasks and reserve admin accounts only for IT staff or trusted personnel who need them.
• Use role-based access control (RBAC) to grant permissions based on job responsibilities.
• Regularly review user accounts and remove access for former employees immediately after they leave the company.

Pro Tip:

Use tools like Microsoft’s Local Administrator Password Solution (LAPS) to manage local admin passwords securely.

---

6. Back Up Your Data Regularly

Ransomware attacks often target SMBs by encrypting critical data and demanding payment for its release. Regular backups are your best defense against such scenarios.

Backup Best Practices:

1. Frequency: Schedule daily backups for critical files and weekly backups for less sensitive data.
2. Storage Options:
   • Use cloud backup services like Backblaze or AWS S3.
   • Maintain offline backups on external hard drives stored in secure locations.
3. Testing: Periodically test your backups by restoring files to ensure they work as expected.

Pro Tip:

Follow the “3-2-1 Rule”: Keep three copies of your data on two different types of storage media, with one copy stored offsite.

---

7. Install Antivirus and Anti-Malware Software

Antivirus software is a foundational layer of defense against malware infections that can compromise sensitive data or disrupt operations.

What to Look For in Antivirus Software:

• Real-time scanning capabilities.
• Behavioral analysis to detect unknown threats.
• Centralized management dashboards for monitoring multiple devices.

Popular options include Windows Defender (built into Windows), Bitdefender GravityZone, and Malwarebytes for Business.

Pro Tip:

Set up regular scans during non-business hours so they don’t interfere with productivity.

8. Educate Employees About Phishing

Human error remains one of the biggest cybersecurity risks for SMBs. Phishing emails trick employees into clicking malicious links or sharing sensitive information.

How to Train Employees:

1. Conduct quarterly training sessions on recognizing phishing attempts.
2. Simulate phishing attacks using tools like KnowBe4 or PhishMe to test employee awareness.
3. Teach employees not to click on unexpected links or attachments—even if they appear legitimate—and verify requests through alternate communication channels.

Pro Tip:

Create a reporting process where employees can flag suspicious emails without fear of repercussions if they make a mistake.

---

9. Disable Unnecessary Features

Unused features and services can become vulnerabilities if left enabled on your systems.

Features to Disable:

• Remote Desktop Protocol (RDP): Unless absolutely necessary, disable RDP as it’s a common target for hackers.
• Legacy Protocols: Turn off outdated protocols like SMBv1 that are no longer secure.
• Auto-run Features: Disable auto-run settings on USB drives and other removable media to prevent malware infections from external devices.

Pro Tip:

Regularly audit system configurations using tools like Microsoft Baseline Security Analyzer (MBSA) or Nessus Essentials.

---

10. Monitor and Audit Your Systems

Regular monitoring helps detect unusual activity before it escalates into a full-blown breach.

How To Monitor:

• Use built-in tools like Windows Event Viewer or Syslog servers for basic log analysis.
• Invest in Security Information and Event Management (SIEM) tools like Splunk or SolarWinds if your budget allows.
• Set up alerts for suspicious activities such as multiple failed login attempts or unauthorized file access.

Pro Tip:

Schedule monthly audits of user activity logs and system configurations as part of your routine maintenance plan.
