Security overseers at last year’s Commonwealth Games on the Gold Coast blocked 40,000 command-and-control connection attempts and identified 39,000 distinct pieces of malware in the fortnight the Games ran.

The numbers were revealed by Glenn Maiden, a national security officer at Cisco A/NZ, on the sidelines of the annual Cisco Live! event in Melbourne last week.
“We served up just under 400 million DNS requests over the two week period, but of that 400 [million], there was about 176,000 pieces of malware that we blocked,” Maiden said.

Maiden said Cisco’s tools caught threats that he believed would otherwise have gone undetected.
“One good example was we saw a time request go to a time server so a computer could get its time - very, very normal, apart from the fact that this was a very multiple megabyte connection.

Watching flows became important because, in Maiden’s words, “one of the big eye openers for us was that almost 50 percent of the traffic that we saw on the network was encrypted.”
