From International Herald Tribune and AP:

Estonia's government on Thursday called for an international convention on combatting computer-based attacks like those directed against the Baltic state in late April-early May.

Global ratification of the convention would establish "a strong legal basis to fight cyber crimes," the Economic Affairs Ministry said in a statement.

Signatory countries would cooperate in preventing computer-related crimes and tracking down organizers of cyber attacks.

The Estonian government also approved a number of measures to bolster the country's defenses against such cyber attacks in the future. In the words of Estonian ministers, future attacks "could be directed against the confidentiality of information systems and integrity of data."

The European Union and NATO, of which both Estonia is a member since 2004, expressed their concern about the cyber war waged against the Baltic country.
