<p>Forged SAML tokens can be observed as authentication attempts with valid signatures but missing expected preceding Kerberos or authentication events. Defenders may correlate SAML assertions with absent Event IDs 4769, 1200, or 1202, or tokens issued with abnormal lifetimes, issuers, or claims compared to baseline.</p>

Log sources and channels

Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.

Mutable elements

Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.

FieldDescription
TokenLifetimeThresholdDefines the maximum expected lifetime of a SAML token (e.g., >1 hour considered anomalous).
TrustedIssuerListList of approved SAML issuers and certificate thumbprints.
