Description

The product's architecture contains too many - or too few - horizontal layers.

Extended Description

This issue makes it more difficult to maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. It also might make it easier to introduce vulnerabilities.

While the interpretation of "expected range" may vary for each product or developer, CISQ recommends a default minimum of 4 layers and maximum of 8 layers.

This table shows the weaknesses and high level categories that are related to this weakness. These relationships are defined to give an overview of the different insight to similar items that may exist at higher and lower levels of abstraction.
