Version control is the systematic management of changes to documents, source code, configurations and other digital assets, maintaining a complete history of all modifications with full traceability. Modern version control systems such as Git enable teams to track who changed what, when and why, whilst supporting parallel development through branching and merging. Beyond software development, version control is increasingly applied to policy documents, infrastructure configurations and compliance artefacts.
In a compliance and security context, version control provides an essential audit trail that demonstrates when changes were made and by whom. It supports change management processes by enabling reviews, approvals and rollbacks of modifications. Organisations that apply version control to their policies, procedures and security configurations can respond more quickly to incidents and demonstrate accountability to auditors and regulators.
