About this interactive

A cybersecurity framework is a blueprint for a security program: it arrives with standards and controls already laid out, so nothing important is missed, and you fill in the details for your organization. The NIST Cybersecurity Framework (CSF) is the simpler of the two the lesson opens. CSF 2.0 groups its outcomes under six functions: Govern, Identify, Protect, Detect, Respond and Recover; Govern was added in version 2.0. Under the functions sit categories (the CSF says categories, not families) and then outcome statements such as "inventories of hardware managed by the organization are maintained." It is voluntary, was first written for critical infrastructure and is now aimed at any organization, and it is often where a smaller organization starts. NIST SP 800-53 is the comprehensive one: a catalog of security and privacy controls organized into families, 20 of them in Revision 5, such as access control (AC), audit and accountability (AU), identification and authentication (IA) and incident response (IR). Each control has a code such as AC-2. Organizations choose their controls with the low, moderate and high baselines, and many controls have assignment or selection blanks to fill in, such as an organization-defined frequency, or whether multi-factor authentication covers local, network or remote access. It is required for U.S. federal information systems and widely adopted beyond them. If a card describes outcomes, functions or a simple starting point, it is the CSF. If it describes control families, codes, baselines or blanks to fill in, it is 800-53.

Key terms

NIST Cybersecurity Framework
NIST CSF
A voluntary framework developed by NIST that provides organizations with a policy framework of computer security guidance for identifying, protecting, detecting, responding to, and recovering from cyberattacks. Originally created for critical infrastructure, CSF 2.0 expanded to address organizations of all sizes and sectors and added a Govern function.
NIST 800-53
A NIST Special Publication that provides a comprehensive catalog of security and privacy controls for federal information systems, organized into control families such as access control, audit, and incident response. It is widely adopted beyond the federal sector as a baseline for security programs.
Cybersecurity Framework
A structured blueprint of standards, controls, and guidance used as a baseline for developing an organization's security policies, procedures, and controls.
Baseline
A documented set of minimum security standards or performance metrics used as a reference point.
