Email Security: Protecting Your Organization from Phishing and Other Threats

The Importance of Email Security

Email security involves implementing measures to protect email communications from unauthorized access, loss, or compromise. Given that over 90% of cyber attacks begin with an email, securing this communication channel is essential for protecting sensitive information and maintaining business continuity.

Common Email Threats

• Phishing: Phishing attacks trick recipients into revealing sensitive information or downloading malware by posing as a trusted entity. These attacks are becoming increasingly sophisticated, making them harder to detect.
• Malware: Malicious software can be delivered via email attachments or links, infecting the recipient’s device and potentially spreading throughout the network.
• Business Email Compromise (BEC): BEC involves attackers gaining access to business email accounts to steal sensitive information or execute fraudulent transactions.
• Spam: While not always malicious, spam emails can clutter inboxes and make it easier for harmful emails to go unnoticed.

Best Practices for Email Security

• Email Filtering: Implement robust email filtering solutions to block spam, phishing attempts, and emails containing malware. This first line of defence can significantly reduce the volume of malicious emails that reach your employees.
• Employee Training: Educate employees about recognizing phishing emails and other email-based threats. Regular training sessions can help employees stay vigilant and avoid falling for scams.
• Multi-Factor Authentication (MFA): Enforce MFA for email accounts to add an extra layer of security. Even if credentials are compromised, MFA can prevent unauthorized access.
• Regular Updates and Patching: Keep your email systems and software up to date with the latest security patches to protect against known vulnerabilities.
