INTRODUCTION

E-mail is a method of exchanging messages ("mail") between people who use electronic devices. In the 1960s, email first entered limited use, but users could only send to others using the same device, and some early email systems also allowed both the sender and the recipient to be online simultaneously, similar to instant messaging. Ray Tomlinson is credited as the inventor of email, as in 1971 he developed the first system able to send mail between users on different hosts across the ARPANET, using the @ sign to link the user name with a destination server. By the mid-1970s this had taken the form now recognized as email.

Email is a popular vector for cyber attacks because of its ubiquity and inherent vulnerabilities,. These attacks can include:

Malware: such as viruses, worms, Trojan horses, and spyware. When attacks using these vectors succeed, an attacker can take control of workstations or servers. This access can then be exploited to compromise otherwise secure information.
Spam: which can be disruptive to worker productivity, and can also serve as a transportation method for malware.
Phishing: which entails the use of computer or social engineering tricks to convince victims to disclose sensitive information, or to provide access to sensitive systems.

Email security is the set of methods used for keeping email correspondence and accounts safe from these attacks.

NSDC Rationale

It’s important that users and organizations take measures to guarantee the security of their email accounts against known attacks, and it’s especially important that a proper infrastructure is in place to stop any unauthorized attempts at accessing accounts or communications. Users are especially susceptible to phishing attacks against businesses, because they sidestep technical security protections, and instead lean into users themselves to expose weaknesses. This is why email security solutions should start with proper techniques like encryption, spyware detection, and login security. But it’s equally important that employees are educated on the proper steps that should be taken to protect email.

With email remaining as the leading threat vector for ransomware, phishing, data theft, and other advanced threats, you can't afford to be left unprotected. Hence I am choosing Barracuda Email Security Gateway to implement on my recent employed organization to mitigate spam emails and email threat issues.
