Weakness (CWE)

CWE-331: Insufficient Entropy

Base Draft

The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

How to prevent it (1 mitigation)
  1. Implementation

    Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
