Open Design: This principle suggests that the design should be open for public scrutiny, which can improve security but doesn't specifically aim to minimize the attack surface. 

Economy of Mechanism: This principle emphasizes that simplicity in design reduces the number of potential errors and, by extension, the attack surface. 

Least Privilege: While this principle restricts what each actor can do to the minimum necessary, thereby potentially reducing the impact of an attack, it doesn't directly aim to minimize the attack surface. 

Defense in Depth: This principle focuses on using multiple layers of security controls. While it enhances security, it doesn't specifically aim to minimize the attack surface.
