NIST CSF Core Notes

NIST Framework Components

The Cybersecurity Framework consists of three main components:

The Framework Core provides a set of desired cybersecurity activities and outcomes using common language that is easy to understand.
The Framework Implementation Tiers assist organizations by providing context on how an organization views cybersecurity risk management.
Framework Profiles are an organization’s unique alignment of their organizational requirements and objectives, risk appetite, and resources against the desired outcomes of the Framework Core.

NIST Core

NIST CSF Tiers

The NIST CSF Tiers represent how well an organization views cybersecurity risk and the processes in place to mitigate risks. This helps provide organizations a benchmark on how their current operations.

Tier 1 – Partial: Organizational cybersecurity risk is not formalized and managed in an ad hoc and sometimes reactive manner. There is also limited awareness of cybersecurity risk management.
Tier 2 – Risk-Informed: There may not be an organizational-wide policy for security risk management. Management handles cybersecurity risk management based on risks as they happen.
Tier 3 – Repeatable: A formal organizational risk management process is followed by a defined security policy.
Tier 4 – Adaptable: An organization at this stage will adapt its cybersecurity policies based on lessons learned and analytics-driven to provide insights and best practices. The organization is constantly learning from the security events that do occur in the organization and will share that information with a larger network.

You can use the NIST CSF to benchmark your current security posture. Going through each category and subcategories in the core Function can help you determine where you stand on the NIST CSF Tier scale.

NIST CSF Profiles

Profiles are an organization’s unique alignment of their organizational requirements and objectives, risk appetite, and resources against the desired outcomes of the Framework Core. Profiles can be used to identify opportunities for improving cybersecurity posture by comparing a “Current” Profile with a “Target” Profile.

Profiles are about optimizing the Cybersecurity Framework to best serve the organization. The Framework is voluntary, so there is no ‘right’ or ‘wrong’ way to do it. One way of approaching profiles is for an organization to map their cybersecurity requirements, mission objectives, and operating methodologies, along with current practices against the subcategories of the Framework Core to create a Current-State Profile. These requirements and objectives can be compared against the current operating state of the organization to gain an understanding of the gaps between the two.
