NIST Cybersecurity Framework Checklist and CTEM Overview

This document is a checklist and overview of the NIST Cybersecurity Framework (CSF) and the Continuous Threat Exposure Management (CTEM) framework. It outlines the importance of the NIST CSF as a guide for organizations to assess and improve their cybersecurity posture through five core functions: Identify, Protect, Detect, Respond, and Recover. The checklist includes steps such as compiling an inventory of devices and establishing cybersecurity guidelines. It also discusses the CTEM framework, introduced by Gartner in 2022, which enhances NIST CSF maturity by providing continuous visibility into an organization's attack surface. The document details the five stages of CTEM, including scoping, discovery, prioritization, validation, and mobilization, emphasizing its role in proactive threat management and incident response. Additionally, it highlights how CTEM supports the CSF's functions by improving detection, response, and recovery processes, thereby strengthening overall cybersecurity management.
