1.5. Summary

When you apply patch management techniques to your Linux computers, you can keep them secure, up to date with the latest services, and nearly bug-free.

In this chapter, you learned to configure repositories and apply patches and updates on RHEL, SUSE, and some other Linux distributions. Subscriptions are required in some cases, which entitle you to keep your systems up to date with the latest patches from specific vendor repositories. As patches can easily run into hundreds of megabytes, it can be helpful to configure a patch management repository on one or more computers on your LAN so that you do not have to pay for an Internet connection where all your computers download updates individually from remote locations.

In the following chapters, you'll learn how to configure and manage local patch repositories on your network.
