tl;dr: NIST released Cybersecurity White Paper 50, a plain-language guide aimed at the 28 million U.S. "solopreneurs" who lack dedicated IT support. It's a scoped-down update to NISTIR 7621, drawing from the NIST Cybersecurity Framework 2.0 but assuming zero prior knowledge, with actionable basics like changing default device passwords, regular backups, and software updates. The document includes worksheets and three hypothetical use cases (a lawyer, artisan, and consultant) to help solo operators build a baseline security program.
