Common Cybersecurity Threats Faced by Small Businesses

By /

Introduction

Nowadays, small businesses are increasingly becoming targets for cybercriminals. Understanding and mitigating common cybersecurity threats is essential to safeguard your business. Here, we delve into these threats and provide practical steps for protection.

Common Cybersecurity Threats

  • Phishing Attacks: Phishing is a deceptive practice where cybercriminals send emails or messages posing as legitimate entities to steal sensitive data. Zscaler reported a 47.2% increase in phishing attacks in 2023 compared to the previous year, highlighting the growing sophistication of these attacks.

  • Ransomware: This malware type encrypts your data, demanding a ransom for its release. In 2023, a study found that 88% of organizations that reported a ‘significant’ increase in email threats were victimized by ransomware.

  • Malware Attacks: Malware can disrupt operations, steal data, and even destroy hardware (computers or computer-operated machines)

  • Unsecured Wi-Fi Networks: An unsecured network can be an easy entry point for attackers.

  • Default Router Configuration: Default settings on routers can be vulnerable. Attackers scan the internet for routers with default login credentials to take control and use them in their cybercrimes.

  • Data Loss: Data loss can occur due to data storage failure, file corruption, user error, or malware. The consequences of losing your and your customer’s data can be catastrophic to a business.

  • Poor Password Management: Weak passwords, shared passwords, or insecure storage of passwords are easy to fix but remain a common security flaw.

Mitigation of Cybersecurity Threats

We have collected recommendations from multiple sources on how you can protect yourself from cyber threats. Some are easy and inexpensive; others will require an investment of time and money. When you read it, remember that paying for prevention is always better and cheaper than paying for recovery from a cyber attack.

Phishing Attacks

  • Training and Awareness: Conduct regular employee training sessions to identify phishing emails and suspicious links.
  • Use Email Filters: Implement advanced email filtering solutions to block phishing emails.
  • Verify Suspicious Communications: Encourage verification of any unusual requests via a separate communication channel.
  • Regular Updates: Keep your systems and security software up to date.
