Am I Safe from the 'Meltdown' & 'Spectre' Chip Flaws?

On the 3rd of January it was revealed that all of the major CPU manufacturers (Intel, AMD & ARM) had major security flaws in their chips. Ominously called ‘Meltdown’ & ‘Spectre’, these flaws allow a cyber criminal to gain access to the data in use by the CPU.

Today we discuss how to best protect your business and how the fallout from ‘Meltdown’ & ‘Spectre’ may affect your business.

How can I make my Network Safe?


The first step is to always keep your software fully updated. Make sure all the updates available for your server and PC’s are performed. Not only will this help secure your network; but the security updates can

sometimes affect other pieces of software. These affected pieces of software will in turn have updates to allow them to run as before.

Be aware, this issue affects the majority of CPU’s, so there will be a lot of updates.


The good news is that in order to utilise ‘Spectre’ & ‘Meltdown’ a cyber criminal must have already installed malicious software on your network. This risk can be mitigated by making sure you have correct Anti-Spam and Anti-Virus software.

For a more detailed study of how to secure your network, take a look at our previous Blogs, notably:

What happens next?


Unfortunately, because the flaws were in the CPU, some of the security patches will affect the speed of your network.

Performing different types of exercises will work different muscles in your body. In the same way, different types of software use the CPU in different ways.

There is no hard and fast rule for how much of a performance drop you may experience; as it affects different types of programs in different ways.

Initial reports thought that CPU performance could have been effected by as much as thirty percent. In the last week, more realistic, estimates place the performance drop between two and twenty percent.

If the thought of a performance drop of this magnitude makes you concerned about the stability of your network, get in contact with your support provider.

With the real impact of these updates yet to take hold, a consultative approach to your relationship with your IT support provider, will serve you well.

Not only keeping your network running well, but setting your business up for a strong 2018.
