名称
Not Failing Securely ('Failing Open')
描述
When the product encounters an error condition or failure, its design requires it to fall back to a state that is less secure than other options that are available, such as selecting the weakest encryption algorithm or using the most permissive access control restrictions.
By entering a less secure state, the product inherits the weaknesses associated with that state, making it easier to compromise. At the least, it causes administrators to have a false sense of security. This weakness typically occurs as a result of wanting to "fail functional" to minimize administration and support costs, instead of "failing safe."
常见后果
范围：Access Control
影响：Bypass Protection Mechanism
注释：Intended access restrictions can be bypassed, which is often contradictory to what the product's administrator expects.
