Being a blue teamer is not an easy thing to do. You need to constantly keep up with the evolving threat landscape and stay up to date. While a red teamer needs to find just one single vulnerability to be successful, a blue teamer needs to watch for everything, as one little error already means that your network could be compromised.

Blue teamers not only need to configure and manage their systems but also analyze large amounts of data and coordinate with other teams. They need to ensure compliance with regulations and standards. And while they do all that, they need to keep the right balance between security and usability, ensuring that their users don’t get overwhelmed with all the security measures and try to bypass them by themselves.

To help keep track of everything that needs to be taken into account, categorizing tasks into protect, detect, and respond types can help. This is an approach to secure your organization’s systems, as...
