For home users our general advice around IT security applies. Make sure all your devices are set, wherever possible, to automatically update. And in this case, check with your hardware supplier’s website to see if they have released a firmware update for your device.
The National Cyber Security Centre has produced a great resource for home users relating to this threat, along with links to the major manufacturers’ advice on this topic.
Will patching impact my systems?
Due to the complexity of modern IT systems there is always a risk of unexpected issues arising during patching that the vendors were not able to test for. It is generally accepted however that, particularly with regards to security flaws, these risks are far outweighed by the risk of not patching.
That being said, due to the nature of these particular flaws and the way they need to be mitigated, there is likely to be an impact on system performance following patching. This is difficult to quantify and will depend on the type of system and the workloads running. The feedback we have from our own patching, and from providers such as Microsoft and Amazon, suggests that any such performance impact will be negligible in most cases. Our advice is still that patches should be applied as soon as possible.
