I have spent the past 6 years of my life running incidents of one flavor or another, whether it was a government or private sector system intrusion, a product vulnerability, or an infrastructure vulnerability or attack. Over the past two weeks I have participated in an incident and the response to the incident that was very different than anything I have personally dealt with before. This incident had two parts to handle: one, the protection offered by the security product RSA SecurID; two, the intrusion itself. This incident demonstrated a deliberate and responsible response by the company, RSA. RSA coordinated a collaborative effort involving the RSA customer community (both U.S. and International), the security community as a whole, law enforcement, and US-CERT.
