In many companies, email quickly becomes an important application, but the mail server must be connected to the Internet to send and receive emails. As you may know, the Internet is never safe. People who want to destroy your server are often on the internet, so one of the secrets of running an Exchange server safely is to not give those people any chance to destroy your server. This article describes some of the technologies that help you secure your Exchange server.
What am I defending?
You might want to know, usually there is no confidential data on the Exchange server, what kind of damage does a malicious user want to cause to the mail server? But there are still a lot of attacks. The most common form of attacking an Exchange server is called a Dos attack, which sends a large number of messages to the server until the server overloads and stops running.
When security is compromised, hackers can steal information. Hackers can burst into the server, access to confidential Data folder permissions, hackers may also use the package leak detection procedures and interception of packets to steal information.
Finally, we should also prevent cheating. Deception is a hacker masquerading as a legitimate user, although deception can steal information, but it can also be used to disseminate error messages. For example, it is easy for a spoof program to send mail in the name of a legitimate user, which may say, "I'm Gone", "the company's president is a big fool", "If I don't meet my requirements, 2 o'clock in the afternoon the company will explode", can be seen that the harm of deception is quite large. Fortunately, there are techniques to prevent these three kinds of damage.
Basis
Some of the most effective technologies used to protect your Exchange servers are basic, but you may find that only these basic technologies are not enough. Basic and advanced security techniques should be used in conjunction. We will review the basic technologies and discuss some of the advanced technologies.
Windows NT
The Exchange server is running in Windows NT because Exchange uses many of the security features of Windows NT, so it is important to ensure that Windows NT is as secure as possible. Windows NT is complex enough to use a book to talk about security, but with limited space, you just need to remember a few questions.
