Defensive guidance

Carnival is providing 24 months of free credit monitoring to affected individuals. The company is conducting thorough analysis of the compromised data. From a defensive standpoint, organizations should enhance resilience against social engineering by implementing phishing-resistant multi-factor authentication, stronger identity verification for internal access, conditional access policies, privileged access segmentation, continuous behavioral monitoring, and targeted red-team exercises focused on human-centric attack vectors.

Summary
