Patch Management

A lot of the time when systems are compromised in a Cyber Security Attack, it is because something that should have been updated hadn’t been! Patch Management.

So, this week we have a look at the various updates that need to be considered. Is your IT support company doing all of this!

Firstly, we will start with the Operating System.

No matter what flavour of system you are using they all need updating, this should include everything from your server, through to your mobile phone. Although manufacturers will rave about the improvements in updates, the biggest reason we think you should install these updates as soon as you can is that they patch critical security holes.

It is also worth bearing in mind that some of these may not be selected to be installed by default. Or your IT support provider may not automatically install them. On operating system updates one of the biggest things, we see is people not restarting their computer.  These updates if they require a restart, are not fully installed until the restart has happened.

Applications

Almost all applications have updates, and a good practice is to make sure these are up to date as well. Especially your web browser, a lot of attacks happen through web browsers this includes a method that bypasses MFA (2FA) So make sure you are updating all of your applications.

If you no longer need an application, then the best thing to do is to uninstall it

Lastly, something you probably have never considered is a piece of software that you won’t normally ever see.

FIRMWARE.

Firmware is software on many devices that control how the hardware operates, these should also be updated. You will find these not only on computers, and servers but switches wifi access points, telephones, printers – The list goes on, and on. You or your IT supplier should make sure these are kept up to date. They are available from the manufacturer, and the systems to keep these up to date have improved over the years. But some are still difficult to know when updates are available.

Whilst looking at the Firmware please remember that when a manufacturer stops updating the firmware this is normally because the device has reached end of life. And even if it is working properly, you should consider changing it,
