Email is one of the most powerful tools for business communication, but it’s also one of the most common entry points for cyberattacks. Phishing scams, malware-laden attachments, and fraudulent emails can compromise sensitive information or even shut down your business.
Recognising this risk, the Australian Cyber Security Centre (ACSC) highlights Email Security as a critical focus area in its Cyber Security Checklist for Small Businesses. By implementing the protections recommended by the ACSC, you can protect your business from phishing, scams, and malware.
Why Email Security Matters
Cybercriminals frequently target email as it provides a simple method to deceive users into disclosing sensitive information or installing harmful software. One click on a phishing email or an infected attachment can result in:
- Data Breaches: Attackers obtain unauthorised access to sensitive business or customer information.
- Ransomware Attacks: Malware can encrypt your data and request payment for its release.
- Financial Fraud: Scammers pose as trusted contacts to coerce employees into transferring funds or divulging credentials.
Small businesses are especially vulnerable, as they might not have the resources for advanced cybersecurity protections. That’s why it’s crucial to implement effective email security measures.
The ACSC’s Recommendations for Email Security
The ACSC Cyber Security Checklist offers practical guidance for small businesses to safeguard their email systems. Here’s how to implement these recommendations effectively:
- Enable Email Filtering
Email filters are your first line of defence, identifying and blocking suspicious emails before they reach your inbox. Set up filters to screen for common threats, such as:- Phishing emails
- Spam
- Malicious attachments or links
- Train Employees to Recognise Phishing
Human error is often the weakest link in cybersecurity. Educate your team to identify warning signs of phishing emails, such as:- Poor spelling or grammar
- Unexpected requests for sensitive information
- Suspicious links or attachments
- Implement Multi-Factor Authentication (MFA). Even if an attacker gains access to an email account, MFA adds an extra layer of security. This ensures only authorised users can access your email systems.
- Ensure Email Accounts Have Strong Passwords
Require employees to use unique and complex passwords for their email accounts. A password manager can assist in generating and securely storing these passwords. - Employ encryption for sensitive emails. Encrypt emails containing sensitive information to safeguard the data during transit. This guarantees that even if the email is intercepted, the contents remain unreadable to potential attackers.
- Regularly update your email security tools. Make sure your email security software, plugins, and systems are kept current to protect against emerging threats.
Benefits of Strong Email Security
By implementing email security measures, you can:
- Prevent Data Breaches: Prevent attackers from accessing sensitive business or customer information.
- Safeguard Against Financial Loss: Minimise the risk of becoming a victim of scams or fraudulent transfers.
- Maintain Trust: Safeguard your reputation by making sure your communication channels are secure.
