Business Email Compromise (BEC) is a growing threat to businesses of all sizes, costing billions of dollars annually. In our previous post, we explored what BEC is and how it works. Now, let’s dive into the first steps to secure your business and reduce the risk of falling victim to these targeted attacks.

1. Use Multi-Factor Authentication (MFA)

Passwords alone are no longer enough to protect your email accounts. Cybercriminals can easily steal or guess them through phishing, brute force attacks, or data breaches. Multi-Factor Authentication (MFA) adds an extra layer of security by requiring users to verify their identity using a second factor, such as:

• A code sent to a mobile device.

• A biometric scan (fingerprint or face recognition).

• A hardware token.

With MFA, even if a password is compromised, the attacker cannot access your account without the second authentication factor.

2. Implement Strong Password Policies

Weak passwords are one of the most common vulnerabilities in any system. Strengthen your defenses by enforcing password policies that require:

• A minimum of 12 characters.

• A mix of uppercase, lowercase, numbers, and special characters.

• Unique passwords for each account.

Encourage employees to use password managers to securely generate and store complex passwords, eliminating the need to remember multiple credentials.

3. Enable Email Encryption

Email encryption ensures that sensitive information remains secure during transmission. Without encryption, cybercriminals can intercept and read your emails, potentially exposing confidential business information. Many email platforms, like Microsoft 365 and Google Workspace, offer built-in encryption tools that are easy to enable.

Encryption works by converting your email content into unreadable code that only the intended recipient can decrypt. This step is especially important for businesses that frequently send financial, legal, or other sensitive data via email.

4. Conduct Regular Security Audits

Evaluate your email system and overall cybersecurity posture regularly to identify potential vulnerabilities. Security audits can include:

• Checking for unused or unnecessary email accounts that could be exploited.

• Verifying that MFA is enabled across all user accounts.

• Reviewing access permissions to ensure only authorized personnel can view sensitive information.

Audits help you stay ahead of potential threats and demonstrate your commitment to securing your business.
