GitHub SAML SSO Disabled

Description

Detects when SAML single sign-on (SSO) is disabled for a GitHub enterprise or organization. SAML SSO delegates authentication to an external identity provider (IdP) and lets administrators enforce IdP-side controls such as MFA, conditional access, and centralized deprovisioning. Disabling it removes those controls and allows members to authenticate with GitHub credentials alone. Following an account takeover, an adversary may disable SSO to evade IdP-enforced access policies and maintain access that survives IdP-side session revocation and deprovisioning, making this a high-impact identity-control change.
