Building Your Security Foundation

Building Your Security Foundation is Book 2 of the Next-Gen Cybersecurity Playbooks series and the practical follow-on to Book 1 (Cybersecurity Basics for Everyone). Written for the person actually responsible for enterprise security at a growing 40-to-400-person organization - the owner, IT lead, ops director, or first security hire - with a small team, a modest budget, and a long list of other responsibilities. Follow the fictional Sentinel Ridge advisory team through ten chapters covering how to move from awareness to action (what a security program actually is, the three-question north star, a program on one page, the quarterly rhythm), sizing the problem (honest asset inventory, data classification in plain English, the crown-jewel map, likelihood impact, your first risk register), identity as the new perimeter (SSO in one picture, the MFA ladder for small teams, least privilege by role, joiner-mover-leaver loop, quarterly access review), endpoint basics (managed vs personal devices, the endpoint protection trio, patch cadence, encryption and screen locks, the lost-laptop playbook), data protection made practical (data-flow sketch, labels people will actually use, retention discipline, the one-page data-handling policy), backups that actually work (the 3-2-1-1-0 rule, test-restore calendar, immutable and air-gapped copies, RTO and RPO), incident response basics (the two-page runbook, first sixty seconds, who owns which decision, first-call tree, tabletop drill), policies people will read (the six that matter, anatomy of a readable policy, approvals without bottlenecks, living policies), building a security culture (ten-minute onboarding, awareness without fear, the reporting culture), and the credible next 90 days (a phased build plan you can actually ship). Written for the practitioner who needs a real program, not a compliance checklist.
