Josephine Wolff wrote for Slate about Estonia's and Ukraine's strong responses to cyberattacks:
The same countries are regularly ranked as having the greatest offensive cyber capabilities—Russia, the United States, Israel, China. But when it comes to the nations with the greatest ability to absorb, withstand, and recover from cyber security incidents, there’s a strong case to be made that we all have something to learn from Eastern Europe. The classic case is Estonia, which bounced back from aggressive denial-of-service attacks in 2007 to become a world leader in promoting international efforts for computer security. But this week’s reports of malware directed at Ukraine’s state power distributor and banks appear to offer another model for how to respond to a cybersecurity breach.
