Rethinking Ransomware Defense at the Filesystem Layer

Most ransomware post-mortems begin at the wrong moment, focusing on the ransom note instead of the attacker's initial access. The critical gap between the attacker's entry and the encryption phase is where defenses can succeed or fail. By implementing an access record and an append-only archive, organizations can significantly reduce their attack surface and enhance real-time detection of anomalies, shifting the focus from backup schedules to proactive monitoring.
