Husin Jazri, director of the Malaysia Cyber Security Agency (MCSA) said the drill reinforces collaboration among participating countries.

"The exercise illustrates the criticality in having immediate access to an effective contact point beyond physical borders across time domains," Jazri said.

"Infrastructure attacks can be mitigated given the speed and competency in dissecting and analyzing evidence and informed decisions can be made in a short time period."

The Korea Information Security Agency developed the drill scenario and initiated the drill. Mr Woo-Han Kim, head of the Korea Information Security Agency (krCERT/CC) said it was designed for international cert collaboration.

"The drill is basically intended as a cross-border incident handling scheme," Mr Woo-Han Kim said.
