Techniques & Countermeasures

  • CWE-385•Covert Timing Channel

    Covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information.

  • CWE-320•Key Management Errors

    Weaknesses in this category are related to errors in the management of cryptographic keys.
