Email security is shielding delicate data in email communication and accounts securing them against unauthorized access, loss, or compromise. The email is very likely a medium for the spread of malware, spam, and phishing attacks, using ambiguous messages to entice recipients to divulge sensitive information, open attachments, or click on hyperlinks that install malware on the victim’s device. Email is additionally a typical entry vector for attackers looking to breach valuable company data.
There are multiple ways to secure email accounts, and for enterprises, it’s a two-pronged approach encompassing employee education and comprehensive security protocols. Best practices for email security include:
Engage employees in ongoing security education around email security risks and therefore avoiding falling victim to phishing attacks over email.
1) Require employees to use strong passwords and mandate password changes periodically.
2) Utilize email encryption to protect both email content and attachments.
3) Implement security best practices for BYOD if your company allows employees to access corporate email on personal devices.
4) Implement scanners and other tools to scan messages and block emails containing malware or other malicious files before they reach your end-users.
End-User email security best practices
Arming your employees with the know-how to avoid risky behaviors can make a substantial impact on your company’s ability to reduce risks associated with email. Email security best practices for end-users/employees include:
1) Never open attachments or click on links in email messages from unknown senders.
2) Change passwords often and use best practices for creating strong passwords.
3) Never share passwords with anyone, including co-workers.
4) Plan to send as little sensitive information as possible via email, and send sensitive information only to recipients who require it.
5) Use spam filters and anti-virus software.
6) When working remotely or on a personal device, use VPN software to access corporate email.
7) Avoid accessing company email from public wi-fi connections.
8) By educating employees on email security and implementing the proper measures to protect email, enterprises can mitigate many of the risks that accompany email usage and stop sensitive data loss or malware infections via email.
