Evidence Vallum Produces
Timestamped audit receipts, evidence packages with cryptographic integrity, signed audit summaries, and retention-compliant archives
Evidence Vallum Does NOT Produce
Application-level business logic logs, third-party system audit trails, or infrastructure monitoring data
Known Limitations
Vallum produces evidence relevant to this control but does not enforce the control at the infrastructure, network, or operating-system level. Evidence covers Vallum-managed operations only. Customer systems, third-party integrations, and infrastructure controls require separate evidence sources.
Your Responsibilities
Configure retention periods, integrate Vallum audit data with organizational SIEM, establish review procedures, and maintain audit infrastructure
External Controls Required
Identity provider (IdP), network firewall and segmentation, infrastructure monitoring, endpoint protection, and organizational security policies
Residual Risk
Vallum evidence covers authorization and evidence-layer operations. Gaps exist at infrastructure, network, and physical layers that require complementary controls. Time-of-check to time-of-use windows exist between evidence capture and verification.
