Firewalls and SBCs are ineffective against DDoS and TDoS
DDoS and TDoS attacks like the ones you cite are now exceeding a terabit of bandwidth.  Firewalls and Session Border Controllers are totally unable to cope with attacks anywhere near this size.  In fact, these days, nearly all botnet driven DDoS or TDoS generates more load than any firewall or SBC can handle.  So suggesting that PSAPs rely on firewalls and SBCs is wrong, which I suspect most DarkReaders know.

Mitiigation of DDoS and TDoS is very possible.  Several mitigation services have multiple terabits of capacity available and can successfully defend against these large attacks.  That's the solution needed.

Individual PSAPs are unlikely to have networks that are designed for and capable of using a mitigation service.  Instead, their connectivity needs to be provided by an Emegency Services IP network that is built to handle such attacks, usually by employing one of the available mitigation services.

Firewalls and SBCs have a place in the security architecture for public safety, but they don't work for denial of service attacks.  Please don't spread misinformation like this.

Life Critical systems
The hack into SONY PICTURES several years ago yielded data, scripts and 5 exposed films for download and that was about it.  911 and hospital systems are, though, LIFE CRITICAL systems.  Same for failures in the payment of Medicare systems and the mess that, for example, CSC made of Englands NHS system.  LIVES DEPEND on some things and 911 is one siuch resource.  (This writer has to be careful as i am also a survivor of 9/11 for all that implies.)   Bringing such down impedes emergency services, timely calls and can involve personal death.  So these are truly critical in the highest sense of the word.  Deserve max protection and monitoring. 

i should add that letting WATSON do cancer diagnosis for patients was an equally horrorific idea.

The Promise and Reality of Cloud Security
Cloud security has been part of the cybersecurity conversation for years but has been on the sidelines for most enterprises. The shift to remote work during the COVID-19 pandemic and digital transformation projects have moved cloud infrastructure front-and-center as enterprises address the associated security risks. This report - a compilation of cutting-edge Black Hat research, in-depth Omdia analysis, and comprehensive Dark Reading reporting - explores how cloud security is rapidly evolving.
