Interstitial Risk: How Combining Two Secure Systems Can Create a Vulnerability

The concept of interstitial risk examines gaps between secure components. When two hardened systems are integrated, unforeseen interactions can emerge. These interactions may expose data or functionality to attackers. The article illustrates scenarios where combined defenses weaken overall security. It stresses the importance of holistic risk assessments during integration. Organizations should test for emergent vulnerabilities beyond individual system audits. Mitigation strategies include layered monitoring and strict interface controls. Recognizing interstitial risk can prevent costly security breaches.
