The memo states: “Less than 0.1 percent of the 30 million known
malicious intrusions on DoD networks between September 2014 and June
2015 compromised a cyber system.” Any way you slice it, the DoD cyber
numbers do not paint a pretty picture.
First, there were “30 million known malicious intrusions on DoD
networks.” That’s 30 million cyber attacks over ten months. That
translates to 3 million attacks per month or 100,000 attacks per day.
Every day.
The “good news” in all this is that 99.9% of those attacks were
thwarted or failed. On the other hand, because of the sheer number of
attacks, there were tens of thousands of successful intrusions. Though
the memo is not clear, less than 0.1 percent of 30 million is less
than 30,000. Thus, in the ten month period ending on June 30, 2015,
there were up to 30,000 cyber attacks on DoD networks that
successfully compromised a cyber system.
