meltdown and spectreIf you use modern PCs, they should have been patched against the Meltdown and Spectre security flaws by now.  Many businesses, however, still use older computers which, while running Windows 10, have not yet had a BIOS update to protect them from the newly found flaws.

How to protect PCs from Meltdown and Spectre

Many clients have asked if there are risks with continuing to run their older PCs with this known critical vulnerability unpatched? Is there an alternative way to mitigate it? Or must they replace their computers with new ones?

In all honesty, it is still too soon to say. Remember that there are still no known exploits for the Meltdown and Spectre vulnerabilities, so the current risk level is low. In the long run, every PC and computing devices will eventually need to be replaced. That would be the case even if Spectre and Meltdown had not been discovered. So, if your devices are approaching the end of their life, it may make sense to replace them sooner rather than later and remove the risk entirely.

What to do to protect against Meltdown and Spectre

Intel says that it has issued firmware updates for nine out of ten of its CPUs from the past five years, but they acknowledge there is more work to do, and there have been reports of strange behaviour in patched PCs, such as a drop in performance and spontaneous reboots.

We recommend that you:

  • update your operating system, web browsers and other software with the latest security patches to defend against threats.
  • If an update is available, update your PC’s BIOS or UEFI.

Only if these are not possible should you consult with your Hull IT Support provider to see if you need to replace your processors or motherboards – or if it is more cost effective to buy new custom-built business PCs.
