Overview

Finding ID Version Rule ID IA Controls Severity
V-235759 EDGE-00-000046 SV-235759r626523_rule High
Description
Sets the minimum supported version of SSL. If this policy is not configured, Microsoft Edge uses a default minimum version, TLS 1.0. If this policy is enabled, the minimum version can be set to one of the following values: "TLSv1", "TLSv1.1" or "TLSv1.2". When set, Microsoft Edge will not use any version of SSL/TLS lower than the specified version. Any unrecognized value is ignored. Policy options mapping: - TLSv1 (tls1) = TLS 1.0 - TLSv1.1 (tls1.1) = TLS 1.1 - TLSv1.2 (tls1.2) = TLS 1.2 NIST SP 800-52 specifies the preferred configurations for government systems.
