A fascinating article in the San Jose Mercury News discusses the recent expansion of public-private partnerships in the growing effort to combat cyber threats from foreign governments and criminals. These partnerships occur through formal agreements between major corporations and government-backed organizations, such as law enforcement, the military or research institutions. The agreements usually involve sharing of intelligence between the government and corporate representatives, as well as participation in threat reporting programs and security exercises. In some cases, the partnerships relate directly to research and development regarding ways to mitigate security threats.
