CentrAlert Products Lead the Way with Security Provisions

Thursday, May 4th, 2017

In the aftermath of the emergency siren system hacking in Dallas, Texas, CentrAlert advises that emergency managers make sure their emergency alert systems are equipped to prevent hacking.


“The Dallas incident serves as a crucial reminder for emergency managers across the country to update their systems to remove vulnerabilities to attacks by unauthorized users,” Jeff Whattam, CEO of CentrAlert, said. “With proper safety and security, citizens can rest assured that alarms are always prepared to function properly if an emergency occurs.”

The Safety of C-DAC

CentrAlert’s Crisis-Driven Alert & Control (C-DAC) product has been equipped with Secure Communication Network (SCN) protocol with integrated, time-based encryption and synchronized algorithms for more than a decade and has never had a reported breach or unauthorized activation.

Each time the operator initiates C-DAC, the Guardian interface sends a unique SCN code to those sirens equipped with CentrAlert’s Remote Terminal Unit. That means the sirens will never go off without the proper SCN code, and a hacker cannot duplicate the codes because they change with each transmission. Additionally, C-DAC’s Hardware Authentication prevents people from using unauthorized software with the system.

Dallas Shutdown

Ultimately, the Dallas emergency management team shut down the entire emergency system to turn off the sirens, leaving the city temporarily without a functioning system. CentrAlert products, on the other hand, require every user to be an authenticated Microsoft Windows user. Therefore, an offending account can be disabled or removed without preventing other users from activating the system should an emergency occur. Whether the hacker is activating the system internally or externally, disabling the account in question will immediately stop the hacker from tampering with the alerts.
