The product has an attack surface whose quantitative measurement exceeds a desirable maximum.
Originating from software security, an "attack surface" measure typically reflects the number of input points and outpoints that can be utilized by an untrusted party, i.e. a potential attacker. In some cases, this measure may reflect other aspects of quality besides security; e.g., a product with many inputs and outputs may require a large number of tests in order to improve code coverage.
