The open source movement makes Source Code available to everyone in an effort to continue to build and improve the functionality of open source software.
What is Open Source software?
A piece of software that is open source is one whose source code is available for anyone to review, edit, and improve.
Most computer users never see the "source code," which is the code that computer programmers can update to alter how a piece of software—a "program" or "application"—works. Programmers can improve a computer program by adding new features or fixing any problematic sections when they have access to the source code.

About Principle of least privilegeIn information security , computer science and other fields, the principle of most privilege ( PoLP ), also known as the principle of minimum privilege or the principle of least authority, requires that within a certain layer of abstraction of the computing environment, every module (such as a process, user, or program , depending on the subject) must be able to access only the necessary information and resources for legitimate purposes.
In principle it means granting a user account or processing only the privileges necessary to perform its intended function. For example, a user account for the sole purpose of creating backups does not need to install software: therefore, it only has rights to run backups and backup-related applications. Other privileges, such as installing new software, are blocked. This principle also applies to users of personal computers who normally work in normal user accounts, and open password-protected accounts only when the situation really demands it.
