1- Physical Security: While a server’s physical security may not be the first thing that comes to mind, it is a critical issue. Any unauthorized party gaining access to a machine, or even a hard drive, is a serious risk. One way to help minimize this risk, even in the event of an intrusion, is by configuring the system to only boot from an internal hard drive. Naturally, a strong password is always a good idea as well.
2- Encrypt Drives: Encrypting drives keeps files secure. Servers using a Trusted Platform Module (TPM) and drives that have been encrypted make it easy for server administrators to access and maintain the appropriate information without jeopardizing server security.
3- Remote Access: Logging into a server locally is no longer the norm. Many webmasters and systems administrators use servers all around the globe, making remote access a common practice. Restricting remote access by IP, using security tokens and using private connections are ways to log in via remote access without putting a server’s security into harm’s way.
4- Verify Software: One of the greatest threats to server security is out-of-date software. One of the primary reasons software providers update products as frequently as they do is to account for potential security threats. Making sure that all software is up-to-date is a critical step in ensuring that your servers are secure. It’s also important to make sure that a server is not using any unnecessary software. The more programs the server is running, the more difficult it is to maintain the server – and the more likely a server administrator is to miss a software update.
5- Use Linux: Linux servers have been historically more secure than their Windows counterparts. Regardless of which operating system a server uses, though, it is important that webmasters and systems administrators are always knowledgeable of the most recent potential threats to their servers. Linux, an open-source platform with a huge global community, tends to offer quicker responses to any potential viruses or attacks because there are so many skilled programmers working together to develop an appropriate security measure.
6- Establish Firewalls: Firewalls serve as distinct barriers that prevent the general public from accessing a server. They serve as guards monitoring both incoming and outgoing traffic to/from a server and determine if the data that traffic requests is appropriate. Users determine what data the firewall should deem appropriate during the initial configuration process.
