Running a Data Breach Response: A Practitioner's Guide to Forensics, Privilege, Notification, and Regulators
By Casey Scott McKay ·
This guide runs a data breach from the first phone call to the post-incident review. It opens with the four hours in which containment, preservation, and the privilege structure are decided, then covers forensic engagement through counsel and how privilege is preserved or lost. It works through the data-element inventory that every legal question depends on, the residence map, and the deadline calendar built backward from the shortest applicable obligation. Later stages cover the risk-of-harm determination and its documentation, the encryption safe harbor, drafting individual and regulator notices across inconsistent state requirements, attorney general and credit agency filings, call center scripting, and the securities and sector obligations that run on their own clocks. It closes with ransomware and sanctions, the litigation that follows, and what to fix before the next one.
