Building Systems Secure From The Start

Filed under

Default operating system installs on a server are almost always wrong. Unfortunate, but true. In an attempt to build a generic system that appeals to as many situations as possible, the default install is often overloaded with software that is not necessary, and a filesystem layout that would allow one rogue daemon to fill up the entire drive. This is wrong, but easily remedied. A little extra care during the installation and initial setup of the server will result in a system that is smaller, cleaner, easier to maintain, and more secure than what ships on a default install.

FIlesystem Layout

I’ve mentioned before how to setup a filesystem to allow for maximum control and flexibility, so I won’t dive into the details here. Suffice to say that the basic idea is to put as much as possible into a volume manager like LVM, and then give each partition only as much as it needs.

Learning The Linux File System

Before we get started, let’s avoid any confusion. There are two meanings to the term “File System” in the wonderful world of computing: First, there is the system of files and the directory structure that all of your data is stored in. Second, is the format scheme that is used to write data on mass storage devices like hard drives and SSD’s. We are going to be talking about the first kind of file system here because the average user will interact with his or her file system every time they use a computer, the format that data is written in on their storage devices is usually of little concern to them. The many different file systems that can be used on storage is really only interesting to hardware geeks and is best saved for another discussion. Now that that’s cleared up, we can press on.
