A cybersecurity framework gives a business a shared language for identifying risk and deciding what to fix first. The three below are the ones organizations most often compare when they want coverage for both financial and internal data.
NIST Cybersecurity Framework
NIST CSF is a voluntary framework from the National Institute of Standards and Technology. It helps organizations define, manage, and reduce cybersecurity risk without pretending every company can follow the same checklist. Implementation can take weeks or years depending on size and risk tolerance. It should be used outside IT as well as inside it.
The framework has three parts: the Core, Implementation Tiers, and Profiles. NIST publishes implementation guides, case studies, and example profiles in plain language.
CIS Controls
The Center for Internet Security Critical Security Controls are a prioritized set of defensive actions. They are designed to stay consistent, stay simple, and stay aligned with other frameworks as threats change. They can be used on their own or alongside NIST CSF.
Typical controls include inventory of software assets, malware defenses, data recovery, application security, and incident response. CIS also publishes implementation material.
ISO/IEC 27001
ISO/IEC 27001 is a certifiable information security management system. It covers information assets such as financial details, intellectual property, employee data, and third-party information. Unlike NIST CSF and CIS Controls, the standard itself is not free. Related: how to get an ISO 27001 certification.
Company size and industry still matter, but these three are a solid starting set. For help choosing and implementing a framework, contact Cyber Security Resource.
