What is Patch Management?

In this video, you will learn how to manage patches.
In this video, we’re going to be taking a look at best practises for patch management. Now when it comes to patching, an out of date OS or operating system is a compromised operating system. It doesn’t matter if you’re running Windows, Linux, or OS X. Every operating system should be patched on a regular basis. These updates are designed to address critical flaws, update services and features. Now I hear this a lot, “It’s OK because I run Linux. It’s OK, I run an Apple.” The truth is, as things become more popular for Apple and Linux, more and more vulnerabilities are going to be found, are being found, and are being exploited.
So again, it doesn’t matter if you’re running Windows, Linux, or OS X, you need to patch your system on a regular basis. Now let me show you real quick how to patch a Windows computer. Now if you’re in Windows 10 already, it’s already going to be set to auto update. But if you want to go ahead and check anyways, you can hit the Windows key, and this will actually work on Windows 8 and Windows 10. And when the search bar comes up, type in “update” and go ahead and go to “Check for Updates”.
Now as you see up here, my Windows is already up to date.
I checked it today at 3:42 PM. But if you want to go ahead and check anyway, you can click on “Check for Updates”. They’ll go go out and force it to take a look for updates. Now let me show you how to update Linux machines. I’m going to just tab over to my Linux machine here and clear the screen here. So this is a Buscador. Buscador is based off of Debian Linux. So if you’re running Debian Linux Buscador, Kali Linux, Ubuntu, Linux Mint, the command is going to be the same. What you want to type in is “Sudo,” and “Sudo” means that you’re running that command as administrator– “space, APT-get update.”
And if you run that, it’s going to go ahead and go through and look for updates. And if there’s an update, it is going to go ahead and update it for you. If there’s no update, then it’ll just clear out like that. So, pretty easy to update a Linux machine, one of the reasons I like Linux a lot. So let’s go back here. Now to update a Mac machine– I don’t have a Mac virtualized here, so I’m going to show you images of it. If you go up in the corner here, you can click on the Apple and go to Software Update. And you could update your operating system from there.
So again, it’s really easy to update, whether you’re on Windows, you’re on an Apple, you’re on Linux. So there’s really no excuse not to update. Now let’s review. Every operating system should be updated on a regular basis. Again, this is going to take care of critical flaws, zero day exploits are found, bugs, and feature updates. It’s going to make your operating system a lot more stable. If your computer’s part of a network, you want to make sure you have some sort of patch management in place. Oftentimes, this is going to be a server that’s going to check all the computers on the network and make sure that they’re up to date.
If they’re not up to date, that’s going to send an update to those computers. Now there’s different programmes for different systems. If you’re on a Windows network, you’re probably going to run a Windows Server and send it through the Windows Update service. If you’re on a Linux machine, there’s various programmes out there to do patch management. And same thing with Apple. If it’s a home computer, make sure you have auto updates on. Again, if you’re running Windows 10, your auto updates is going to be enabled automatically. If you’re on Windows 8 or 8.1, there is an option actually set to auto update.
So you do want to go and do that, if you’re not going to check on a regular basis. And again, if you’re on Linux or Apple, make sure that you manually go in there– I would say every week– and just click that button, see if there’s update, and go ahead and update it. Again, absolutely important to make sure your operating system is up to date. So that was about patch management. Next, we’re going to be exploring what makes a good password. Thanks for watching. I’ll see you in the next video.

In this video, you will learn how to manage patches. Patches are designed to address bugs or flaws and update services and features on your system. Out-of-date software may be a cybersecurity risk.
