This function helps you understand your digital environment, pinpointing the systems, assets, and data that are crucial to your operations. It’s about making sure you have a clear map of your terrain. 

2. Protect

With your map in hand, the next step is to fortify your defences. This function focuses on implementing safeguards to ensure your critical services stay up and running, even in the face of cyber threats. It’s about building the walls and defences that keep your business safe. 

3. Detect

A strong defence is vital, but you also need to know when it’s being tested. The Detect function is your surveillance system, designed to quickly spot any signs of a cybersecurity event. It’s your lookout on the tower, keeping an eye out for trouble on the horizon. 

4. Respond

Despite your best efforts, breaches can happen. The Respond function is your action plan for when they do. It outlines how to manage and mitigate the impact of a cybersecurity incident. Think of it as your emergency response team, ready to jump into action at a moment’s notice. 

5. Recover

After a storm, it’s time to rebuild. The Recover function helps you restore any services or capabilities that were impaired during an incident. It’s about getting back on your feet, repairing the damage, and learning from the experience to come back stronger. 

6. Govern

The new kid on the block, the Govern function, ties everything together. It emphasizes the importance of leadership and governance in managing cybersecurity risks. This isn’t about adding more red tape; it’s about ensuring that everyone from the boardroom to the IT department is on the same page. Working together to safeguard the organization.
