Updating Your IT – Part 3 – Security

 

In the final instalment this week, we’ll look at how keeping your IT updated affects your security.

Viruses, Worms, Trojans, Malware, Phishing – all different kinds of cyber-attacks, all out to steal valuable information or cause destruction or inconvenience in one way or another, and you could be putting your information at increased risk from these if your IT is outdated. You may have antivirus software on your computer, and assume that you’re protected. But when was it last updated? What year is it from? Do you tell Windows to shut down without installing its updates, or have Windows Update turned off? Are your machines, servers or network too slow to run up to date security software effectively? These are all things that could compromise your security.

While there are methods of making your hardware more secure, most of the real threats to security come from out of date software interacting with the internet. Slower hardware may struggle to run some of the security software available and necessary for businesses today, and if that’s the case, you may need to consider some hardware upgrades as well.

So what can you do? Well, there are some steps you can take right now:

  • Make sure Windows Update is turned on if you’re running a PC, or MacUpdate if you’re running a Mac.
  • Make sure you have up-to-date antivirus software.
  • Set your passwords to something that’s not easy to guess. A combination of upper and lower case letters, numbers and symbols is best.
  • Check that you have the most recent version of your chosen browser.
  • Check that all of your important software is up to date.

Out-of-date software can leave serious security holes open to potential hackers, (not to mention a variety of bugs,) so always use the tools provided by the vendor to update your software whenever an update is available.

Often, in larger organisations,  things like updating software and virus definitions is something that is also done by a network administrator or IT support technician, but with standalone machines or some small business networks, this may not be the case.

Unless you understand your IT fully, things like updating firmware for routers and checking network settings are something that’s best left to the professionals, and something that should be included in your IT support package.

Recently in the news, large companies like Sony have come under fire for not fixing security holes in their systems, or not having strict enough policies and allowing details to get out. No one wants this to happen, especially with very sensitive data that some businesses store, and one of the first steps you can take toward security is to keep everything up to date.
