      Simple way to hack elections: Compromise some county offices & systems. Do nothing. If election doesn’t go your way, reveal that you hacked.

      In particular, for a state actor trying to disrupt, casting legitimate doubt on election outcome is often as good as picking the winner.

      NSA report says 122 (unnamed) local gov’t election officials were sent mal email, but doesn’t discuss any forensics done on their networks.

      It looks like NSA’s investigation chiefly involved analysis of the gmail accounts used for the spearphishing, but not the targets’ systems.

      That may be due to NSA lacking authority to do investigations on US systems; I wonder if FBI/DHS/etc was also investigating.

      In any case, that leaked document is both very interesting and clearly not the full story, And county election systems REALLY need audits.

      Note that that NSA report was written only a month ago; it’s possible that the investigation continues, including audits of those systems.

      Sounds to me that post-Snowden, they have a lot more auditing installed.

      Auditing on county voting systems?

      I meant on NSA internal systems, so that they could identify who downloaded that document--but auditing voting-related systems is important.

      Is that necessarily clear? A translator is going to come through on her PKI, Snowden is going to come in as Sysadmin.

          It's the confusion about which/how many files Snowden downloaded--logs should have shown that. But you alarm differently for a sysadmin.

          Right. There are no SMP requirements that techs be auditable. On the contrary. But the ones for analysts, etc are quite stringent.

          Yup. So--do you filter at log time or audit time? Typically, you'd do the latter, unless the volume was overwhelming.

          I'm not sure I understand distinction but I admit i'm very tired.

          Logging is keeping the raw access data. Alarming tells someone about unusual patterns. Auditing is understanding why someone saw something.

          That stuff I get -- it was the filtering that threw me.

          If you're collecting too much data, discard early. It may be too much for your disk or your analytics; more likely, collection slows things.

          Wrt Snowden, or now? Wasn't that the delay in implementing the insider threat thing that might have covered Snowden?
