Phosphorus Password Management for xIoT Devices is a credential management solution focused on IoT, OT, and IIoT (collectively referred to as xIoT) environments. It addresses the widespread issue of default and weak credentials on xIoT devices by automating credential discovery, enrollment, and rotation. Key functions include: - Automated identification of devices using default or weak credentials - Continuous, scheduled rotation of passwords across xIoT device fleets - Enrollment of discovered devices into a built-in Password Vault - Integration with external Privileged Access Management (PAM) platforms for centralized credential storage and management The solution targets common attack vectors such as botnet exploitation (e.g., Mirai) that leverage default credentials on networked devices. It also supports regulatory compliance requirements by enforcing strong authentication policies across IoT and OT environments. Phosphorus positions this capability as part of a broader Cyber-Physical System (CPS) security platform that includes vulnerability management and device hardening. The password management module applies credential hygiene practices to xIoT devices in a manner analogous to how traditional IT asset management tools handle credential rotation for servers and workstations.
