[EAS] Why information sharing is important for warning security

[Sean Donelan]

Information sharing between organizations is important for security, 
because there are almost always precursors. Secrecy about security 
problems often just means more victims later. Sharing lessons learned 
with other groups may not just help them, but may also help you.

Now Fort Worth officials think a similar radio signal attack occured in 
2012 and 2014 with its city-wide warning sirens.  At the time, it was 
blamed on a "software bug," but they were never able to find a specific 
software bug.

People talking about the Dallas incident on outdoor siren mailing lists 
say siren controllers malfunction for lots of reasons, i.e. animals and 
insects, equipment age, operator error, accidental co-channel 
interference, etc. Even though I used to be paid, with legal 
authorization, to break into systems; I tend to be skeptical when people 
too quickly blame "hackers." Often it takes a while to exclude other 
potential causes.
