Volume 20 February 2018 Edition MassAlert™ employs a credential hierarchy to ensure users and administrators only have access to appropri- ate functions. No one security scheme is appropriate for all possible communication backbones, but ATI can work with cus- tomers to maximize security for their system. Also, storage of critical system data is encrypted and ATI’s remote unit controller hardware includes watchdogs on program operation and Cyclical Redundancy Checks on stored program code. False Alarms Caused by Human Errors Finally, newer ATI sirens have an updated IP stack that in- cludes modern security options, such as Transport Layer Security (TLS) for protection of communication running over IP links such as Ethernet, fiber optics, Wi-Fi, or satellite. Many newer modems and radios include their own security and encryption options which run all the way to military grade in higher To avoid false alarms or catastrophic human errors, ATI’s MassAlert® software adopts a “two-point” validation concept. This design is to prevent accidental system activations by a single individual. ATI developed a unique solution to be able to provide a clear, intelligible direction to the public to protect them in an emergency situation, such as active shooter, a weather emergency or a manmade disaster. end units. 11
