- Purpose of Frameworks: Frameworks are used as a starting point to develop plans that mitigate risks, threats, and vulnerabilities to sensitive data and assets.
- Global Usage: Organizations worldwide create frameworks to help security professionals develop effective plans.
- Scope: NIST frameworks support ongoing security efforts for various organizations, including for-profit, non-profit, and government agencies.
- Global Influence: Although NIST is US-based, its guidance is valuable to analysts globally.
- Nature: A voluntary framework consisting of standards, guidelines, and best practices to manage cybersecurity risk.
- Core Functions:
- Identify
- Protect
- Detect
- Respond
- Recover
- Application Example:
- Incident: High-risk notification of a compromised workstation with an unknown device.
- Steps Taken:
- Identify the compromised workstation.
- Block the unknown device remotely.
- Remove the infected workstation.
- Use tools to detect additional threats.
- Investigate the incident (who, how, what, where).
- Recover affected files or data and correct damage.
- Purpose: Provides a unified framework for protecting the security of information systems within the US federal government.
- Application: Used to maintain the CIA triad for government systems, including those provided by private companies for federal use.
- Frameworks and Controls: Work together to develop plans to handle incidents, lower risk, protect organizations, and mitigate vulnerabilities.
- NIST CSF: Widely respected and essential for maintaining security.
- NIST SP 800-53: Crucial for those interested in working with or for the US federal government.
- Core Functions: Understanding and applying the five core functions of the NIST CSF.
- Framework Integration: Recognizing how frameworks like NIST CSF and SP 800-53 work together to enhance security.
