100 Days to CIS Benchmarks Implementation

This guide outlines a practical 100-day roadmap for implementing Center for Internet Security (CIS) Benchmarks to strengthen organizational cybersecurity and align with frameworks such as NIST SP 800-53. It explains how standardized configuration controls harden operating systems, applications, networks, and cloud services, reducing risk and improving compliance. The paper walks through preparation, scoping, baselining, automation, deployment, monitoring, and ongoing maintenance, emphasizing cross-team coordination and continuous compliance. By automating configuration management and remediation, agencies can replace months of manual effort with repeatable processes, quickly establish secure baselines, limit configuration drift, and support broader initiatives such as Zero Trust while using existing staff and resources.
