Episode 54 — Control third-party access and high-risk integrations

This episode covers third-party access and integrations as a high-risk area because the ISA exam often tests whether you can spot hidden access paths and unclear responsibility boundaries that undermine otherwise strong controls. You’ll define what “third-party access” includes in real environments, such as vendors with remote support tools, outsourced administrators, managed security services, payment gateways, SaaS platforms, and API-based integrations that exchange transaction data or influence payment workflows. We’ll discuss how to design strong controls, including scoped access, MFA enforcement, time-bound approvals, dedicated vendor accounts, strong logging, and clear offboarding procedures when contracts change or staff rotate. You’ll learn how to validate third-party controls through evidence such as access request records, identity provider policies, session logs, and contracts that clearly assign responsibilities for patching, monitoring, and incident response. Troubleshooting scenarios will include vendors using shared credentials, persistent “temporary” access that never gets removed, integrations that bypass WAF controls, and missing logs for vendor activity, along with practical remediation steps that preserve business service levels without sacrificing governance.
