Version Management
Start course

This course covers section three of CSSLP Domain Four: Secure Coding Operations. You'll learn about code analysis, code reviews, secure build environments, anti-tampering techniques, and version management.

Learning Objectives

  • Learn how to analyze code and review it
  • Understand how to ensure that build environments are secure
  • Understand the importance of anti-tampering techniques and version control when building software

Intended Audience

This course is intended for anyone looking to develop secure software as well as those studying for the CSSLP certification.


Any experience relating to information security would be advantageous, but not essential. All topics discussed are thoroughly explained and presented in a way allowing the information to be absorbed by everyone, regardless of experience within the security field.


Now, none of this will come to much unless we have proper versioning and configuration management. So we have version control that ensures that the development team is working with the current correct version of code and versioning provides the ability to track ownership and changes of that code. It also enables rollback to a previous version if that should become required. Doing this can reduce the instances of a condition known as regenerative bugs, and this occurs when bug fixes are overwritten when incorrect versions are used.

We want to be sure that the bugs we've killed stay dead. So we use this as a method of making sure of that. Now version control configuration management has become increasingly important and continues to be more important as software projects grow in complexity and size. Like so many of our practices, it needs to be done at all unit levels, unit stream, module, subsystem all the way through the complete end-to-end system. And it needs to be coordinated to ensure that all the units are tracking to the same master stage to ensure that we're not getting things confused or out of sequence.
