A Look at the Security of Your Email Server

As we’ve witnessed in the 2016 presidential campaign, email server security is not a subject to be taken lightly. Studies show on average businesses have a 1 in 3 chance of getting hacked.

With hackers becoming increasingly smarter and skillful by the day, it’s important to maintain your email server security and follow best practices. Here’s what you need to know when it comes to email server security:

The Dangers Your Email Server Faces

If a hacker gets into your email server and takes hold of your company files, there’s little you can do to protect yourself at that point. Attackers can use your information against you to do a variety of things. Such as controlling your company, accessing confidential information or threatening you with ransom.

For example, last year, the vehicle hire company MNH Platinum fell victim to a virus that encrypted over 12,000 of their files, threatening their entire business. A ransom threat followed demanding more than £3,000 for their files back.

The largest target for these types of attacks are small/medium businesses (SMBs). According to the latest statistics from Symantec, more than half (52.4%) of the phishing attacks carried out last year were against SMBs.

Email is a frequent target of malicious attacks for many reasons. It’s been around for a while, so hackers have had a lot of time to understand how it works. It’s also widely used and always available to attack. And it’s typically used to communicate with untrusted, external organizations.

Here are some of the most common threats to email servers that SMBs should know about:

Malware and Viruses

Possibly the most well-known way hackers attempt to get into your emails is by sending malicious software full of viruses, worms, Trojan horses, and spyware to your inbox. When you open the emails, the danger releases onto your email server and computer, giving the hacker control over your workstation and server.

From there, they can monitor and control your activity and access your sensitive information.


Phishing is when you get an email that looks very, very similar to a trusted source, such as your boss or coworker. The intent of this practice is to convince the receiver to reveal personal information, such as passwords or financial numbers and secrets.


As discussed earlier, ransomware is when a hacker has a hold of all of your data, encrypts it, and demands a ransom from you in exchange for the decryption key.

Social Engineering

Social engineering is different from the previous methods because it doesn’t attempt to hack into your system. Instead, the attacker tracks your email and your activity with it to gather sensitive information such as address or phone number.

Once they have enough information, they may attempt to get into your email by correctly answering security questions, for example.

How to Protect Against These Dangers

Cyber security expert Sarah Green says that one of the most dangerous mentalities for a small business to adopt is: “It’ll never happen to us.” It’s never safe to assume that your network and email server are safe from harm. You should always at least adopt the basics. In fact, around 80% of cyber breaches can be stopped from simple, security basics, such as:

Educate Your Employees

The first step is to train your employees on basic email knowledge. Conduct awareness and training activities to educate your employees on how to effectively recognize malicious and suspicious messages, and how to handle them so they don’t fall victim.

Set Control Settings

As an administrator, it’s important to control your overall network environment and its settings as well. For example, limit the access your employees have to certain controls. Allow them enough authority on programs to just do their job. Give them all different passwords as well. These precautions will prevent human error mistakes such as wiping out the email server, or putting important access and information in the wrong hands.

Other security measures to take could also involve risk assessments, configuration management and change control, malware scanning and spam filtering tools, firewalls, and intrusion detection and prevention systems.

Constantly Update

Updates will keep hackers on their toes. How? Well, if you have the same email server system for a while, that gives them a lot of time to learn how it works and how to better hack it. If you constantly upgrade it, your security just gets tighter and tighter. Updates will also be better at detecting spam emails, which is always a good thing.

Frequently Test Your Security Strength

It’s always a smart idea to periodically test your security measures to assess its strengths and weaknesses. You can do this through periodic vulnerability scanning.

Encryption, Encryption, Encryption

Encryption is the process of converting information into a code to prevent unauthorized access. With encrypted data, only the intended receiver will have the authority to view this data. This protects your information from outside hackers who don’t have the right credentials. Encryption should be implemented as a very minimum in any company’s email server security practices.
