New paper: “Lessons Lost: Incident Response in the Age of Cyber Insurance and Breach Attorneys“:

Abstract: Incident Response (IR) allows victim firms to detect, contain, and recover from security incidents. It should also help the wider community avoid similar attacks in the future. In pursuit of these goals, technical practitioners are increasingly influenced by stakeholders like cyber insurers and lawyers. This paper explores these impacts via a multi-stage, mixed methods research design that involved 69 expert interviews, data on commercial relationships, and an online validation workshop.

The second stage showed that lawyers when directing incident response often: introduce legalistic contractual and communication steps that slow-down incident response; advise IR practitioners not to write down remediation steps or to produce formal reports; and restrict access to any documents produced…
