As a company that values its online reputation, you need to take measures to secure this vital channel of communicating with your stakeholders. If you do not take this security concern seriously, you may end up on the wrong side of the law or losing your corporate reputation. This post will bring you to date with practical ideas that will help you to safeguard your email network from hackers.

But why should you care?

Before delving into the details of how to protect your email servers, let us take a brief look at why you need to do it in the first place. Here are the reasons why you need to keep hackers at bay:

  • It will cut off spamming, which(spamming) can lead to unnecessary complaints against your domains and IP addresses
  • It will stop hackers from hijacking your email accounts and using them to spam other people aiming at reducing your subscription since you will be deemed a spammer
  • It will protect you from being blacklisted by your subscribers
  • It will keep away hackers from using your email addresses to spam or even harass people, and hence, you will not end up in blacklists

Keep your email username and password confidential

To keep your servers secure, you should be careful how your employees handle the usernames and access codes of the company. They should never disclose such information to anyone because doing so will open a door for hackers to access your email accounts and do their dirty work.

Be careful how you change your security questions and answers

Another way of indemnifying your system is taking care of how you select and answer your security questions. You should ensure that your answers are easy to remember, do not or cannot change along the way, and someone cannot guess or research them. For instance, it will be suicidal if a public figure used their wedding date, the school they attended, or their mother’s name because such information is in public domain.

Encryption

As you secure your email servers, it is necessary to use secure connections. You should encrypt the POP3 and IMAP verifications and take advantage of Exchange server SSL certificates to indemnify your network.

Limit and control default settings

Another way of keeping your email server secure is taking care of your system’s default settings. You need to disable unnecessary server functionalities by deactivating all unnecessary default settings that can compromise your server’s safety.

Safeguard your computers

If you want to complete the equation of securing your email servers, you have to protect your computers. The reason is that computers are the important media of accessing email servers and failure to indemnify them exposes your entire system to hackers. To achieve security at this level, you ought to install a credible antivirus and update it regularly. Therefore, we strongly recommend you install a paid antivirus because most free versions are limited and they lack features that can protect you from hacking.

Control access

Alongside the installation of an Exchange Server SSL, controlling access to your server is another way of securing it. You have to guard your server against unauthorized access by ensuring that every person who wants to send emails from your system does so using a controlled and authorized username and access code. Additionally, you should restrict such access to a few trustworthy persons.

Prevent abuse

Do you still want to indemnify your email on Exchange Server? Then you need to pay attention to blacklists based on DSNs. You should check all the domains and IPs contained in these blacklists and reject any message that emanates from them. To secure your servers further, use outbound filters and CAPTCHA on all your online forms.

Complicated your email address

As much as possible, you should use email addresses that are not too easy to guess. For instance, using David576@gmail.com is safer than using david@hotmail.com. Alternatively, you can use a name you have coined yourself. For instance, if you are Hassan Patel Young, you can coin a name out of it like: Haspatung@yahoo.com. In this example, you have created a name that no one can guess, and more so, there is no creature under the sun with such a name.

Use secure passwords

To keep your email servers safe from hackers, you need to pay attention to the security of your email passwords because they are the entry points for them. When choosing a password for your business’s email accounts, you should do so with tact so that it becomes difficult for the bad boys to guess them. First, you need to ensure that the password is not a name of a person, place, or anything is in public domain. For example, choosing a password like “Saint Peter” only exposes you to easy hacking.

Therefore, you need to choose a complicated password with both figures and letters. Moreover, you can mix small and capital letters. A good password could read something like this: ttH5mtc#. By integrating figures and symbols into the access code, you make it difficult for hackers to crack your system through guesswork.
