Most of the Netherlands lies below sea level. This risk has been recognized and measures have been taken to protect us against the water. The Netherlands is divided into a number of areas, and dikes have been built around all of them. In a few cases, concerning vulnerable areas and/or very expensive contents, an extra dike has been added.
None of the dikes are of equal height. In determining the height, the local risk was taken into account. In fact, a risk analysis has been prepared for all parts of our country and measures have been taken based on that analysis. If a dike breaches, the damage will remain limited to that one part.
In IT security, we call these areas ‘security zone segments’. The extent of the protection of a segment depends on its vulnerability and the value of the data in that segment. Just as with the dikes, it’s all about having a proper analysis and a well-thought-out strategy.
