Small Business Email Security: Stop & Think Before You Act on That Email!

Did you know that hastily responding to an email could cost your business thousands of pounds? The culprit is a ‘Business Email Compromise (BEC)’ attack, and it’s on the rise among small businesses.

In Small Business Email Security, it’s vital to understand the risks of BEC attacks. Cybercriminals impersonate a senior figure in your company, exploiting the trust between employees to pilfer money or sensitive information. Though it might seem like an issue for big corporations, small and medium-sized businesses are equally in the line of fire.hands typing on a keyboard. next to keyboard pad and pen, coffee cup 'Small Business Email Security'

The Enormity of Business Email Compromise Attacks

  • According to the FBI, BEC attacks have drained businesses of over £20 billion in the past few years.
  • Microsoft reports that BEC attacks are evolving, becoming more destructive and trickier to detect.
  • Small local businesses, such as yours, are particularly vulnerable as they often lack comprehensive IT support.

“But I use antivirus and antispam software; isn’t that enough?”

Unfortunately, no. The sophistication of these attacks has surpassed basic email protections. It’s high time to get serious about your small business email security.

How to Defend Your Business Against BEC Attacks

  1. Educate Your Employees: Your employees are the frontline against BEC attacks. Empower them with knowledge on:
    • Spotting phishing emails and fake invoices
    • Cybersecurity best practices like strong passwords, multi-factor authentication, and secure file sharing

      Employee training isn’t just an investment in security – it’s an investment in your business.

  2. Implement Advanced Email Security Solutions: Employ cutting-edge technology to detect and fend off BEC attacks. Find a provider that offers:
    • Domain-based Message Authentication, Reporting & Conformance (DMARC)
    • Sender Policy Framework (SPF)
    • DomainKeys Identified Mail (DKIM)
  3. Establish Transaction Verification Procedures: Before approving transactions or sharing sensitive information, verify requests through phone calls or video conferences. Don’t solely rely on email confirmations.
  4. Monitor Email Traffic: Stay vigilant. Regularly review email traffic for anomalies, like unknown senders or unusual login locations. Have a clear protocol for reporting and responding to suspicious activities.
  5. Keep Software Up-to-date: Regularly update your operating system, email software, and applications. These updates often come with security patches that seal known vulnerabilities.

Time waits for no one. Take these preventive measures today and protect your business from costly compromises.

Deep Dive into Small Business Email Security Measures

Let’s deep dive into practical tips that your small business can employ to fortify its email security.

Craft a Strong Email Policy

  • Having a well-defined email policy sets the foundation for robust small business email security.
  • Outline the dos and don’ts for your employees, clearly stating the kind of information that should not be shared via email.

Pro Tip: Make it a practice to include a standard legal disclaimer at the end of all company emails. This might not prevent attacks, but it could protect you legally.

Train Employees on Recognizing Phishing Scams

  1. Check Email Addresses: Train your staff to hover over email addresses to check for any discrepancies.
  2. Analyze Email Content: Poor grammar, vague content, or an urgent request are red flags.
  3. Be Wary of Attachments and Links: Teach them not to open any suspicious attachments or links.

Implement Two-Factor Authentication (2FA)

  • Use 2FA for all email accounts. This adds an extra layer of security, as attackers would need both the password and a second piece of information.

Keep Communication Lines Open

  • Foster an environment where employees can freely communicate any unusual email or requests they receive.
  • Hold regular meetings to discuss and share experiences regarding email security.

Work with Vendors and Partners

  • Communicate your security policies with your vendors and partners.
  • Encourage them to implement similar security measures, creating a fortified network of protection.

Regularly Audit and Monitor

  • Conduct regular audits of your email system.
  • Use monitoring tools to track login attempts, mailbox rules, and forwarding rules.

Pro Tip: Set up email alerts for suspicious activity.

Employ Email Encryption

  • Encryption ensures that only the intended recipient can read the email.
  • Several email providers offer built-in encryption, make sure to activate it.

Develop an Incident Response Plan

  • In case of a BEC attack, an incident response plan is essential.
  • Ensure your plan includes steps on how to contain the attack, eradicate the threat, recover, and learn from the incident.

  • Regularly evaluate the effectiveness of your security measures and be willing to make changes as needed.
