Security Recommendations for End-User

The Next Generation Low Water Cut-Off device has been tailored for boiler safety application, as such most security hardening is already in place. The following guidance provides recommendation for customers for hardening the operating environment, secure operations, account management and disposal. In the table below: Safeguard describes the security guidance, Security Context & Rationale provides overview of security features and value of the security safeguard, and References provide additional resources for further investigation for implementing the recommended safeguards

Safeguard	Security Context & Rationale	References
Restrict physical access • Ensure physical access to assets is limit‐ ed. Include physical isolation to protect the environment and equipment therein. • Ensure strict control over physical access in and out of the cus‐ tomer’s facility.	The communication channel is hardened to restrict access and ensure integrity of device operations. BLE pairing requires proximity and pressing physical button on device. This safeguard supports the ability to fur‐ ther limit exposure associated with physical threats to the device it‐ self.	ATT&CK for ICS: M0801 NIST SP 800-53 Rev. 5: AC-3 ISA/IEC 62443-3-3: SR 2.1
Each account should be tied to an individual. Or‐ ganizations should con‐ trol individual accounts through policy.	Mobile application re‐ quires registration and authentication, and se‐ curity events are logged. This safeguard ensures all activities are traceable and non-repudiable.	ATT&CK for ICS: M0801 NIST SP 800-53 Rev. 5: AC-3 (7) ISA/IEC 62443-3-3: SR 1.1
Ensure physical button is not pressed continuously / again and again, after putting device in Configuration Mode so that the device does not re-enter Configuration Mode unexpectedly and enable al‐ ternative access to your data.	Protections, such as the physical button, are put in place to make pairing deliberate and to require physical proximity to the device. This safeguard provides additional checks and ensures no fingerprinting of BLE devices takes place.	NIST SP 800-53 Rev. 5: AC-18 ISA/IEC 62443-4-2: CR.4.1, NDR.1.6
Ensure Bluetooth signal cannot be received outside the organization- controlled boundaries by employing emission security and purposefully positioning the device.	Multiple BLE pairing mechanisms are available to ensure availability of data. This safeguard reduces the liklihood of capturing or intercepting signals.	ATT&CK for ICS: M0806 NIST SP 800-53 Rev. 5: AC-18, SC-40 ISA/IEC 62443-3: SR 5.2
Implement specific inventory, logging and monitor‐ ing for hardware and report security-related incidents associated with devices to Xylem. These might include unexpected operations, confirmed tampering, or theft of the device.	Devices are hardened and Xylem provides PSIRT to help customers investigate potential security incidents. This safeguard supports the ability to track assets and recognize potential security events.	ATT&CK for ICS: M0947 NIST SP 800-53 Rev. 5: SM-8 ISA/IEC 62443-3-3:2013: SR 1.11, SR 2.8, SR 3.4
Ensure cybersecurity policies, awareness, and training to the operators, administrators and other personnel.	While the system has been hardened in many ways, this safeguard pre‐vents Social Engineering attacks and promotes awareness related to cy‐ bersecurity.	NIST SP 800-53 Rev. 5: AT-2 ISA/IEC 62443-2-4: SP.01
Before device disposal clear all paired connec‐ tions.	No data is persistent on the device, but BLE bonding is enabled for gathering of data. This safeguard ensures that no one can connect to your device using al‐ ready-paired devices.	ATT&CK for ICS ID: M0942 NIST SP 800-53 Rev5: SR-12 ISA/IEC 62443-3-3: SR 4.2
