Definition • Information Warfare (my definition) • “The use of digital technologies to damage the critical infrastructure of a state” • So, • Damage – destruction, demolition, devastation. • Critical infrastructure - no more Web sites breaking • State - no more photo sending “analyzers”. • But, yes, still digital technologies – but not too much. • And, yes, politics – but not today.

Introduction to IW How is information warfare different from your every day Attack?
Targets • Who? • Infrastructure Companies, including power, water and communication. • Financial institutions. • Government & Army. • What? • Destruction of equipments • Destruction of control systems • How? • Time bombs.
Attacker Capabilities • Financial resources • Technical expertise • Intelligence • Legal flexibility Section: Introduction to IW
Financial & Technical Resources • Hundreds, thousands… of man-years per project. • Duplication of any system at target. • Ability to actively seek vulnerabilities, especially in lesser known systems. • Usage of custom attack code per target. Security by obscurity is no longer an option
Intelligence & legal issues • Human intelligence …. Spies • Best of bread “social engineering”: pay, blackmail, steal. • Operate spies to access internal systems. • Signal intelligence … Communication interception • A global sniffer: clear text password. • Intelligence about systems and topology. • Legal immunity to attacker. License to crack

Examples Is it all for real?
Model Case Studies • Shutting down communication switches, thus preventing phone services. • Destroying power generators. • Derailing trains. • Exploding refineries and other chemical plants. • Crashing air-planes.
Solutions So, What can I do to avoid such disasters?
Solutions • Use layered security. • Deploy stronger intra-organization security mechanisms. • Strengthen complementary security mechanisms such as physical security and employees assurance. • Allocate independent security resources to operational networks. • Strive for world peace.
