How is Windows Update for Processor Security Bugs Helpful?

Summary: Microsoft has identified two security bugs named ‘Meltdown’ and ‘Spectre’ in processors that have affected all CPUs released after 1995. Google also confirmed the issues in the processors, adding that the affected processors were of Intel, AMD, and ARM. Read this blog to get all Information about these bugs.

How is Windows Update for Processor Security Bugs Helpful?

To fix these bugs, Microsoft released security updates for supported versions of Windows on 3rd Jan 2018. The updates are thought to resolve a number of issues identified with the processors. The updates are also available for older versions of Windows like Windows 7 & 8. In Windows 10, the updates are automatically installed and users would rarely see a difference.

But, the Windows update alone is not sufficient to resolve the issue. The solution to this issue also relies on the firmware update by Intel, AMD, and others. Some anti-virus software developers will also have to introduce updates compatible with the new patch, as the changes will affect the Kernel-level accesses.

Are you protected against ‘Meltdown’ and ‘Spectre’?

Meltdown and Spectre do not just hamper the performance of your system, but it also allows hackers and attackers to utilize the JavaScript in the browser to gain access to your data through the attackers’ process. Through this terminal, the hacker can access your content that contains passwords, keystrokes, and other valuable data.

For a consumer, keeping the Windows up-to-date must be the first priority among other things like installing application Firmware update, etc.

Microsoft has released the following patch to address the Meltdown and Spectre bugs:

KB4056892 (OS Build 16299.192)
KB4056891 (OS Build 15063.850)
KB4056890 (OS Build 14393.2007)
KB4056888 (OS Build 10586.1356)
KB4056893 (OS Build 10240.17738)

PowerShell verification using the PowerShell Gallery (Windows Server 2016 or WMF 5.0/5.1)
Install the PowerShell module
PS> Install-Module SpeculationControl
Run the PowerShell module to validate the protections are enabled
PS> # Save the current execution policy so it can be reset
PS> $SaveExecutionPolicy = Get-ExecutionPolicy
PS> Set-ExecutionPolicy RemoteSigned -Scope Currentuser
PS> Import-Module SpeculationControl
PS> Get-SpeculationControlSettings
PS> # Reset the execution policy to the original state
PS> Set-ExecutionPolicy $SaveExecutionPolicy -Scope Currentuser
