As polls close & *unofficial* results post, it's prime time for the 4 Ds of Election Night Reporting (ENR) disruption:
Demand - legit overdemand causes outage
Defacement - changing website content
Denial of Service - bad guys cause outage
Disinfo - fake news abt results
Keep in mind that results posted on ENR systems are unofficial and don't touch your vote, the count, or certification process! So if you see any of the 4Ds, Keep Calm! Let em' count.
I also want to thank @CISAgov's federal partners at @FBI@NSAGov@US_CYBERCOM@ODNIgov@EACgov for all the hard work, preparation, planning, and support over the last 3.5 yrs. An honor to be a part of this team defending democracy.
Yesterday, I issued an emergency directive to US civilian agencies requiring immediate actions to protect Federal information systems from ongoing DNS hijacking and tampering activities. This activity was first raised to CISA by partners in the internet security community. 1/7
We are aware of a number of agencies affected by the tampering activities and have notified them. In part, by issuing the directive, CISA seeks to work with agencies to detect and prevent additional impacts on agencies and systems. 2/7
The directive lays out a set of risk-informed, straightforward, and high impact/low burden actions that agencies must take to harden systems and improve awareness and trustworthiness of key security processes. 3/7
