EMAIL SECURITY

Email security is a term for describing different procedures and techniques for protecting email accounts, content, and communication against unauthorized access, loss or compromise. Email is often used to spread malware, spam and phishing attacks. Attackers use deceptive messages to entice recipients to part with sensitive information, open attachments or click on hyperlinks that install malware on the victim’s device. Email is also a common entry point for attackers looking to gain a foothold in an enterprise network and obtain valuable data.

Types of firewalls

There are software and hardware firewalls. Each format serves a different but important purpose. A hardware firewall is physical, like a broadband router — stored between your network and gateway. A software firewall is internal — a program on your computer that works through port numbers and applications.

Use strong passwords and mandate frequent password changes. This helps to ensure that, even if a password is compromised, its use can be limited.

Ensure that webmail applications use encryption. This is standard functionality, but critical to prevent emails from being intercepted by malicious actors.

Implement scanners and other tools to scan messages and block emails containing malware or other malicious files before they reach end users. 

A robust cybersecurity program or a dedicated spyware removal service that can dispose of malicious email attachments and repair altered files/settings.

Encryption technologies such as OpenPGP let users encrypt emails between sender and recipient. This is a necessity for businesses where sensitive information is shared frequently via communication platforms like email.

This is a software program scans each incoming and outgoing email for malicious content and blocks their entry or exit, as the case may be.
