Countermeasure Techniques

Distributed capability for isolating and neutralizing attacks:

• Countermeasure via restriction: a defensive measure to restrict amount of resources available to an attacker
• Countermeasure via defection: provide an "off-ramp" for an attacker's traffic via coordinated shutdown of interfaces
• Countermeasure via isolation: provide active re-routing to provide isolation at coarse-level (e.g. autonomous systems)
• Countermeasure via counterattack: automated backtracing and offensive attack suppression
