"I think these cyber exercises are incredibly useful and important, mainly because they uncover gaps and coordination issues in organizational processes," Litan said.
Often, functional silos are major impediments to fast response in cyberattack situations, especially in large organizations, Litan said.
"Several divisions have to coordinate their response in a very timely fashion. This involves, for example, working across divisions for threat intelligence, security operations, network operations and also some hosting service providers."
Exercises like Quantum Dawn 2 allow "organizations to flesh out their internal processes as well as test the technologies and management processes they have for dealing with the attacks," she said.
Simulated cyberattacks are useful given the proliferation of cloud technologies and an increasingly dispersed workforce, said Narsi Kodukula, vice president of product strategy at security vendor CipherCloud. "Given the complexity and rapid nature of the tech evolution, simulations that help identify weaknesses as well as foster information sharing," are vital, he said.
