In order to prevent this, you need to encrypt both incoming and outgoing mail. Passwords, user names, and messages themselves can be intercepted. When an email is sent via the internet, it goes through unprotected communication channels. Personal data is one of the key targets for hackers. We'll look at this in more detail in a section that covers various problems with performance and stability. Different types of servers use different operating systems, interfaces, etc.Īnother way to protect the server from cracking is SMTP authentication. Everything else depends on the server type. This prevents the password from being cracked via brute force, which is a universal way to bypass authentication. The first thing you need to do to avoid this is to establish strong requirements for the password used to access the server. ![]() One widespread type of attack is when a perpetrator tries to bypass the authentication procedure in order to get access to data. These best practices and problems that can arise when you don’t follow them will be the focus of the next part of this article. In order to do this, we need to stick to best practices when setting up email server security. Of course, dealing with all of them is impossible, but we can greatly reduce their number. Potential vulnerabilitiesĮvery system has vulnerabilities, so every system is at risk of a cybersecurity breach. We'll also talk about some features of certain email servers and examples of their vulnerabilities, together with general recommendations for testing. We'll show examples of security measures and various problems that can arise if you don’t adhere to them. In order to avoid data loss, problems with stability and other troubles, we need to adhere to general recommendations on how to set up an email server and monitor its security in order to detect and immediately fix any vulnerabilities. 1.3 Standard methods of software protection When a server is unstable, it can lead to the loss of customers. It's also important for a server to run stably so that users are able to access it at any time. And for businesses, in particular, loss of confidential information can result in large financial losses. Security for an email server is particularly important because email is one of the most popular means of communication and doing business. This is why servers are attractive targets for malicious attacks. Not to mention that the stability of your whole system depends on servers. While it's impossible to imagine the modern world without constant communications over networks, almost all valuable data that's a target for attacks is stored in various forms on servers. With the constant development of information technology, the role of cybersecurity is getting ever bigger.
