CSF

Cybersecurity Framework (CSF) Summary

The Cybersecurity Framework (CSF) is a set of guidelines aimed at helping organizations better protect their critical infrastructure from cyber threats. Developed by the National Institute of Standards and Technology (NIST), this voluntary framework provides a flexible, risk-based approach to managing cybersecurity risks.

Key Components of CSF

CSF comprises three key components:

• Core - Consists of five functions, each representing a high-level cybersecurity activity:

  • Identify: Understand the organization’s cybersecurity risks.
  • Protect: Implement safeguards to protect the critical infrastructure.
  • Detect: Identify the occurrence of a potential cybersecurity event.
  • Respond: Develop and implement appropriate actions to address detected cybersecurity events.
  • Recover: Implement plans to restore systems and services after a cybersecurity incident.

• Tiers - Provide context for organizations to consider the robustness of their cybersecurity program:

  • Tier 1: Partial – Minimal cybersecurity risk management practices.
  • Tier 2: Risk Informed – Risk management practices in place, but not consistently applied.
  • Tier 3: Repeatable – Risk management practices are consistent across the organization.
  • Tier 4: Adaptive – Proactive approach to managing cybersecurity risks.

• Profiles - Organizations create profiles to align their cybersecurity activities with their organizational goals, risk tolerance, and resources. A target profile represents desired outcomes, whereas a current profile reflects the current state of cybersecurity programs.

Benefits of Implementing CSF

• Enhanced understanding of cybersecurity risks and corresponding management strategies within an organization.
• Improved ability to prioritize cybersecurity investments based on risk assessments.
• Strengthened communication between different departments and stakeholders regarding cybersecurity expectations and progress.
• Compliance with industry standards and guidelines, including support for organizations subject to regulatory requirements.

CSF offers organizations a structured approach to improving their cybersecurity posture. By following this framework, organizations can manage their cybersecurity risks more effectively, create a stronger defense against cyberattacks, and maintain the resilience of their critical infrastructure.
