When I read about the NIST security framework for the first-time unfortunately the details entered one ear and promptly exited the other, I needed some way to retain the information, so its time use an anlogy…. Navigating cybersecurity in an organisation can be likened to a chef perfecting a complex recipe. The NIST Cybersecurity Framework (CSF) serves as a comprehensive cookbook, ensuring all ingredients blend harmoniously and are safeguarded from potential spoilage (cyber threats).

1. Recipe Development: The Framework’s Origin In 2014, NIST unveiled the CSF, much like publishing a master chef’s recipe book initially intended for the likes of Gordan Ramsey (and critical infrastructures). NIST, is renowned for its unbiased and expert guidance (scientific data), they later tailored this recipe book for a broader range of kitchens, from small local bistros to expansive corporate dining facilities, enhancing its versatility and applicability. One cookbook to rule them all!

2. The Chef’s Toolkit: Components of the CSF The CSF comprises three essential kitchen tools:

• Core (The Chef’s Essentials): This is the primary set of recipes and techniques – Identify, Protect, Detect, Respond, and Recover. Imagine a chef identifying key ingredients, protecting them from spoilage, detecting any signs of problems, responding to culinary challenges, and recovering from any kitchen mishaps.
• Tiers (Kitchen Skill Levels): These tiers, from 1 to 4, assess the sophistication of your kitchen and culinary skills. A Tier 1 kitchen might be just starting out, while a Tier 4 kitchen boasts advanced, well-integrated cooking practices.
• Profiles (Customised Cooking Recipes): Consider these as tailored recipes created by culinary experts, specific to the types of cuisine and conditions of your kitchen, helping to bring current culinary practices to your own kitchen.

3. Mastering the Culinary Art: Implementing the CSF Adopting the CSF is like embarking on a kitchen renovation project. It starts with assessing the current state of the kitchen (security operations), identifying which ingredients are fresh and which are at risk of spoiling, and then prioritising areas for improvement. An action plan is akin to a cooking schedule, ensuring all aspects of the kitchen function smoothly. CISA’s guidance, in this context, is akin to advice from a master chef, offering detailed steps for a successful culinary venture.

4. Diverse Cuisines: Industries Embracing the CSF Since its introduction, the CSF has evolved, much like a recipe adapting with new ingredients and cooking techniques. Its alignment with global security practices helps various industry kitchens thrive while meeting shared regulatory requirements, similar to ensuring restaurants in a community adhere to local health and safety standards.

5. Savouring the Success: Key Takeaways The NIST CSF is a versatile guide, adaptable to any organisational kitchen, whether it’s a small café or a vast gourmet restaurant. Implementing it, though challenging, ensures a healthy, resilient kitchen capable of withstanding culinary crises. Like any kitchen, staying attuned to the latest in food safety and cooking trends (risk, threat, and vulnerability trends) is crucial for success.

For a detailed guide on mastering your organisational kitchen using the CSF, explore the CISA report, which is like a special edition of a culinary guidebook for commercial kitchens.

Mnemonic for Remembering Core, Tiers, and Profiles To easily remember the components of the CSF – Core, Tiers, and Profiles – think of the mnemonic “Chef’s Top Pick”:

• Chef’s (Core): The chef’s essential recipes and techniques.
• Top (Tiers): The levels of kitchen maturity and sophistication.
• Pick (Profiles): The chef’s selected, customised culinary plans.

To remember the five functions of the NIST Cybersecurity Framework core – Identify, Protect, Detect, Respond, and Recover – you can use the mnemonic “IPDRR”:

• I for Identify: Recognising critical assets and cyber risks.
• P for Protect: Safeguarding systems against threats.
• D for Detect: Spotting potential cybersecurity events.
• R for Respond: Addressing detected cybersecurity incidents.
• R for Recover: Restoring capabilities or services impaired by a cybersecurity event.

1. Identify becomes Inspect Ingredients:
   • Like a chef inspecting ingredients before cooking, this stage involves recognising critical assets and cyber risks in your IT environment.
2. Protect transforms into Prepare Safeguards:
   • Similar to a chef preparing and safeguarding ingredients for cooking, this involves implementing measures to shield systems against cyber threats.
3. Detect is akin to Detecting Changes in Flavour:
   • Just as a chef stays alert by sampling food’s flavour or texture, this stage is about spotting potential cybersecurity events or anomalies.
4. Respond turns into Reacting to Culinary Challenges:
   • Comparable to a chef reacting to unexpected issues while cooking, this involves addressing and managing detected cybersecurity incidents effectively.
5. Recover equates to Reworking the Dish:
   • Much like a chef fixing a dish that didn’t turn out as expected, this stage focuses on restoring and improving systems or services impaired by a cybersecurity event.

Bon appetite!
