We have updated the Speculative Execution Side-Channel Vulnerabilities Configuration Baseline. The updated baseline now includes support for verifying the protections for CVE-2018-3620 (L1 Terminal Fault) in addition to the previously supported CVE-2017-5715, CVE-2017-5754 and CVE-2018-3639.
This Compliance Settings configuration baseline is used to confirm whether a system has enabled the mitigations needed to protect against the speculative-execution side-channel vulnerabilities as described in the Microsoft Security Advisories ADV180002, ADV180012 and ADV180018. It is based on the functionality in the PowerShell module Get_SpeculationControlSettings. It requires at least PowerShell 3.0.
