An API is hosted onsite and is using only header-based Identity Mapping.

When applications depend solely onheader-based identity mapping, attackers can attempt to bypass PingAccess by injecting headers directly into requests sent to the backend. To prevent spoofing, PingAccess should be configured to passcryptographically verifiable tokens(e.g.,ID tokens from OIDC) instead of relying on plain headers.

Exact Extract:

“Headers can be spoofed if not protected. Use signed tokens, such as ID tokens or JWTs, to provide strong identity assurance and prevent header injection attacks.”

Option A (Use ID Tokens)is correct — ID tokens are signed and verifiable, preventing spoofing.

Option B (Add Site Authenticator)protects PingAccess-to-site authentication, not client-to-API spoofing.

Option C (Require HTTPS)prevents eavesdropping but does not stop header spoofing from inside the network.

Option D (Use Target Host Header)ensures host header integrity but not user identity.
