Central Processing Unit (CPU) Vulnerabilities

Computer code

Many of you have recently read of the Meltdown and Spectre vulnerabilities in the news. Below is information regarding the vulnerabilities and what you can do to keep you and your local devices safe.

What are the Meltdown and Spectre vulnerabilities that have been in the news?

These vulnerabilities are design flaws identified in the Central Processing Unit (CPU) of most computers. Certain features of the CPUs can be abused to allow a malicious program running on a computer to access data in the memory of the computer that it shouldn't be able to access. For example, a malicious program could access information in the operating system's memory such as a password, encryption key or other sensitive data. A malicious program could also access information in memory that belongs to another program or user.

What do I need to do?

Everyone's IT situation is different, so it is important to ensure that you are taking the necessary steps to protect your computer from these vulnerabilities. A few practices that you can utilize are listed below.


Ultimately, these vulnerabilities can only be exploited by malicious code being run on your systems. Training yourself to be aware of security issues and how to properly handle email and web browsing goes a long way toward protecting yourself from not only this but future vulnerabilities as well.
