Privacy Issues in Big Data Processing in light of Data Breaches
summary
Five high-profile breaches show the attack vectors and failed protections: third-party credentials let attackers pivot into Target and Home Depot, FireEye alerts get ignored, Chase exposes about 76 million households and 7 million businesses, Anthem loses 78.8 million records unencrypted, Ashley Madison stored weakly normalized passwords, and OPM leaks enable foreign intelligence picks. Practical mitigations include collecting less PII, using salted and format-preserving encryption, strict role-based access, behavioral analytics for insider abuse, and mandatory two-factor authentication.
