RESTORING TRUST IN EMAIL COMMUNICATIONS, ONE COMPANY AT A TIME
Today’s Business Email Scenario:
There is no doubt that in today’s world of unified communication, there are many platforms available to convey, communicate with your end users, vendors, partners, and any external business entities. However when it comes to formal communications, Email is the most widely used communication channel.
Any formal business communications are done over email undoubtedly. While it is a critical communication channel mostly used for official or formal communication, Simple Mail Transfer Protocol (SMTP), which guides how email is sent from one computer to another, allows for a computer to identify any domain as its sending domain and/or from address. This vulnerability is one way email is being exploited massively. It has become the primary channel of target, exploited by cybercriminals to lure, attract and even defame an organization or its users.
Initially, the authentication methods available were few and simple, SPF being one of them; however, as technology advanced, so did the authentication methods and the protection levels they provided. DKIM was developed next and then DMARC. By utilizing the sending domain’s DNS (Domain Name System) as the base for authenticating a sender’s credentials, receivers can verify the incoming mail is truly being sent and authorized by the domain the sender is identifying as.
