Patch management isn't sexy

It is VERY Important

Patch management isn’t something most business owners think about. Some will tell you they’ve turned on automatic updates. So, that’s it, you’re good right? Not so fast.

Update Command Line

Desktop, Laptops, and their software

Desktops and laptops with automatic updates turned on will receive microsoft updates on “Patch Tuesday”. The day named because Microsoft typically releases patches on a Tuesday of a month. If you have windows 10 you have more options in the name of “rings” or a distrobution track.

What about the other software on your machines? How often are they updated? At the time of this writing, Adobe Reader has no less than 100 vulnerabilities listed. That’s just one popular software program. Add in Office, java, flash, and the other software installed on your systems the time needed to managed these updates starts to add up.

Updates fail

Sometimes, updates fail. Microsoft isn’t great about making sure you realize an update has failed. Busy employees certainly don’t usually notice the little popup displayed.

WFailed Windows 10 Updatehen they fail, the vulnerability is still present on your system. Why they failed can be a number of reasons, but it is a common occurrence.

Unless you’re running a vulnerability scan on your network against your machines you wouldn’t know this information.

Why is it important?

Viruses and Hackers

Currently Petya ransomware is spreading and one of the channels is windows folder sharing flaw via an email. You may not have windows shares setup, but you’re Windows machine does. It has two that you may not even know about. C$ and Admin$. This is only an example, but petya is about to cost companies close to a Billion dollars.

System Issues

Many times those updates and patches are created because a flaw in the software. Not installing updates also means you could be susceptible to coding mistakes or conflicts. They can be costly but usually just annoying. However why take the risk when patches and hot fixes are free?

 Installting Updates Caution

Managing patches and updates on machines doesn’t have to be hard. Our customers enjoy the freedom of knowing we’re watching for failed updates, vulnerabilities, and virus intrusions. For those want to manage this you’ll need to touch every machine and check the update logs for Windows. In addition you will need to check each of the programs installed and see if they are on the latest version. Sounds tedious? That’s because it is. Even with 4-5 machines it can take a few hours out of your day.

Servers need updates too

Your business servers, on-site or VPS, also need patches. The Equifax breach was due to web server software that wasn’t updated. The patches were available that would have stopped it. I’m sure the CEO of Equifax and CIO had a very uncomfortable discussion on why they weren’t applied.

On-Site Servers

Your servers are the life blood of your network. They house your data, perform tasks, and typically run critical software. Most businesses use an on-site Window server and it needs the same patch/upgrade management that your desktops do. Server patch management typically runs on a monthly schedule because those same patches can break crucial software your business needs. They have to be applied carefully and in the event of a problem, uninstalled until Microsoft releases an updated version of that patch.

VPS or CO-LO servers

So you have a VPS server and unless it’s managed, most are not, you are probably responsible for updates and patches. Linux can feel tricky to update and some Linux distributions need a special update command for security updates and hotfixes. Other’s do not. If you’re unsure if your VPS is managed, call your provider and ask.

So if it’s managed, I’m good right? Maybe not. You’re at the mercy of your provider and when they install patches. Only a security assessment of the server will tell you if it’s vulnerable or not. We can help with that assessment. If it is vulnerable or has missing patches/updates, you can ask the provider when they will update the server. You may want to consider moving your VPS service to a new provider.

It’s boring but necessary

Patch management is boring but necessary. If you made it this far in the article, we’re impressed! It also means you have a concern about how this is being managed at your company.
