Mitigation MIT-56
Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation
Requirements

Select a programming language that is not susceptible to these issues.

Mitigation
Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation
Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation
Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
