CWE-1044: Architecture with Number of Horizontal Layers Outside of Expected Range
Learn about CWE-1044 (Architecture with Number of Horizontal Layers Outside of Expected Range), its security impact, exploitation methods, and prevention guidelines.
What is Architecture with Number of Horizontal Layers Outside of Expected Range?
• Overview: Architecture with Number of Horizontal Layers Outside of Expected Range (CWE-1044) occurs when a software product's architecture has too many or too few horizontal layers, which can complicate maintenance and indirectly affect security.
• Exploitation Methods:
- Attackers can exploit complex architectures by identifying and leveraging unmaintained or poorly understood layers.
- Common attack patterns include targeting less monitored or outdated layers that may have vulnerabilities.
• Security Impact:
- Direct consequences include increased difficulty in patching or updating the system, leading to prolonged exposure to known vulnerabilities.
- Potential cascading effects involve introducing new vulnerabilities during maintenance or updates due to the complex architecture.
- Business impact includes increased costs in development and maintenance, as well as potential reputation damage if vulnerabilities are exploited.
• Prevention Guidelines:
- Specific code-level fixes involve refactoring the architecture to ensure a manageable number of layers, ideally between 4 and 8.
- Security best practices include regular architecture reviews and maintaining clear documentation to understand and manage layers effectively.
- Recommended tools and frameworks include using architecture analysis tools to assess and optimize the number of layers and employing modular frameworks that encourage layered architecture.
