Blog Post Shout Out: Meltdown , Spectre Article and WPA3

I wish to provide a respectful shout out to the following articles for providing useful information on emerging vulnerabilities and technologies.

With the large media coverage of the Meltdown and Spectre CPU hardware vulnerabilities (including this blog!) the following Ars Technica article is particularly useful since it describes in detail (but still in an easy to understand manner) how two CPU instructions present in modern CPUs help to alleviate the performance impact.

The article also describes (all in one place) the 3 mitigations Intel have added to their CPUs using a microcode update. AMD CPUs meanwhile added 2 mitigations (the difference in numbers is also explained).

=======================

With the announcement of the new wireless security protocol WPA3 at CES earlier this month; it was relatively easy to learn of the security changes the new WiFi standard will introduce. These changes are very welcome with the publication of the KRACK vulnerability for WPA2 last year. However the questions I wanted to know the answers for were not as straightforward:

  1. While devices with WPA3 are set to be made available in 2018; will they arrive late or earlier this year?
  2. Are the WPA2 devices I have now likely to work with a new WPA3 router?
  3. Will it be pointless to have a WPA3 router if all or most of my devices are WPA2 since it cannot provide both standards of security at the same time?

All of the above questions are addressed in this How to Geek article. I hope you find these articles helpful. Thank you.
