Communications and Security: Email security

Email has become inevitable mode of communication in our day-to-day life. Even though there are many new technologies like chat, messenger and video chats are in the market, email still has its value. Email is preferred for both formal and informal communications. Email has its own weakness and it is prone to threats. Let us see some of the techniques we can use to have secure communication via email.

Create a Unique Password: Using same password for all the email accounts is not advisable. If one account is attacked eventually all the other accounts having same password will be attacked. In the worst case, we must have a unique password at least for the master account which has all you potential details.

Encrypt your data: Data sent through email must be encrypted. Double encryption can be done to protect sensitive data. This will help to prevent the loss of data.

Use digital certificates: Sign all your sites using digital certificates. Good practice is to save your digital certificates in routers or load balancers rather than web servers.

Spam filter on email servers: Use any spam filter to avoid spam. SpamAssassin is an Apache software which prevents unwanted email from entering your inbox.

Scan for Viruses & Malware: If something in your mail looks suspicious, run the malware and virus scanner. Virus does not affect your inbox every time but still it is safe to safe to run virus scanner every time.
