Mitigation
Phase: Architecture and Design
Description:
- Choose a language that provides automatic memory management.
Mitigation
Phase: Implementation
Description:
- When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
