While Bloomberg's findings may be a narrow view of the cyber attack landscape, it contains some positive news for system defenders, according to Michael Kaiser, executive director of the National Cyber Security Alliance in Washington, D.C.
"We've known for a long time that large enterprises have been doing a better job at defending themselves," he told PCWorld.
"So to see some of the largest brands in the world being able to resist attacks or mitigate their impact, is a good sign," he asserted.
Nevertheless, he added: "There's a huge arena of small- and medium-sized enterprises which are extremely vulnerable. Sometimes they're attacked to get a backdoor into these larger enterprises that are more defended."
