Removing access means revoking the contractor's permissions to access the project data, systems, and devices
after the project is closed. This is a crucial security measure to prevent unauthorized access, misuse, or theft of
sensitive data by external parties. Closing contracts, project sign-off, and project evaluation are important steps
in the project closure process, but they do not necessarily prevent data theft by themselves. They may involve
formal agreements, documentation, and feedback, but they do not address the technical aspects of data
security. References = CompTIA Project+ Study Guide: Exam PK0-005, Third Edition, Chapter 14: Closing
