CWE-353: Missing Support for Integrity Check

Base Draft

The product uses a transmission protocol that does not include a mechanism for verifying the integrity of the data during transmission, such as a checksum.

More detail

The end-to-end philosophy of checks states that integrity checks should be performed at the lowest level that they can be completely implemented. Excluding further sanity checks and input validation performed by applications, the protocol's checksum is the most important level of checksum, since it can be performed more completely than at any previous level and takes into account entire messages, as opposed to single packets.

How to prevent it (2 mitigations)

  1. Architecture and Design

    Add an appropriately sized checksum to the protocol, ensuring that data received may be simply validated before it is parsed and used.

  2. Implementation

    Ensure that the checksums present in the protocol design are properly implemented and added to each message before it is sent.
