5 Costly Mistakes in Cyber Incident Response Preparation
Summary: A Dragos Principal Incident Responder describes five common preparation gaps that inflate the time, personnel, downtime, and expense of handling a cybersecurity incident. The gaps include missing current network topology and asset documentation, an undrilled Incident Response Plan that lacks separate IT and OT sections, absent or unretained security logging, no Collection Management Framework, and no incident response retainer.
What you should know: Without retained logs and a documented plan, key historical evidence is lost and can never be replaced, and responders must reconstruct the environment at consulting rates. Dragos also reports responding to incidents where inexperienced firms destroyed evidence and aggressively scanned sensitive industrial devices, which can cause almost as much damage as the adversary.
