Ensure 'Control where security restrictions on insecure origins apply' is set to 'Disabled'

AltaNivel 1Automatizadaedge

Descripción

This policy setting allows for a specified list of origins (URLs) or hostname patterns (like "*.contoso.com") for which security restrictions on insecure origins don´t apply. Allowed origins for legacy applications that can´t deploy TLS or set up a staging server for internal web development so that developers can test features requiring secure contexts without having to deploy TLS on the staging server. Rationale: Insecure contexts should always be labeled as insecure. The policy is Disabled when it is not present: the audit prints 'absent' when neither the value OverrideSecurityRestrictionsOnInsecureOrigin nor a populated list subkey OverrideSecurityRestrictionsOnInsecureOrigin exists under HKLM\SOFTWARE\Policies\Microsoft\Edge, otherwise the configured entries.
