Malware spreads among email clients mostly thanks to infected attachments. The damage that a DoS attack can do to a mail server is hard to overstate. It leads to unreceived and unsent emails, not to mention time spent trying to restore the service.
Ultimately, the reputation of the whole company suffers. To prevent such a threat, you need at least to limit the number of possible connections to the SMTP server. In order to cope with SMTP security issues, look into limiting the overall number of connections over time, as well as simultaneous connections. If your server is attacked and stops working, you need to have a plan B. In such cases, we often use a reserve server.
For email servers, in particular, this is done by having two MX records for each domain. Email servers also have an option to use SMTP authentication. It's very important to enable SMTP authentication. It allows you to protect the server from an attack consisting of numerous sent requests, ensuring continuous operation.
It's also very important to configure the mail relay. You can specify from which IP addresses the server can send mail. You can also prevent a large number of messages from being sent to destabilize the server.
Another filter for email sent from clients is Reverse DNS. It's used to compare an IP address with the domain and hostname. It also serves to protect the server from malicious mail. One of the most relevant best practices is to not store anything unnecessary on the server.
You need to carefully consider whether additional software, installed on a server can be used by a perpetrator. Check each of your open network ports to make sure that they're necessary and if not, immediately close them and protected for example, check whether authorization is required to send data via a port.
You also need to update all the software on the server. There are whole lists of software vulnerabilities that are easily accessible for malicious hackers. When new vulnerability or exploit is detected, software vendors will usually issue a fix over the course of several days. Also, you should trust a server only to people who will be responsible for it. At the start, it's necessary to design the approach that will be used to monitor mail server security.
In many cases, it's easier to look at the available solutions. Numerous companies provide cybersecurity audits. But in certain cases, it can be necessary to solve the problem yourself.
How tough and formal this process should be depended on the task at hand. First, you need to decide what you need to check, why and how. All three questions are important because you need to cover as much ground as you can with your audit without wasting your time on unnecessary details. After that, we need to make a decision on whether each entry is worth the resources necessary to run it. We need to estimate the time and money needed to buy software, train employees and execute checks.
After forming the list, you can establish the scope of work and necessary resources. Depending on the breakdown, you can also create a detailed plan that will fully cover every procedure from start to finish.
With the checklist, the process boils down to conducting the checks covered in the Products and Utilities sections of this article.
