The security principle that is violated by running all processes as root or administrator is the "principle of least privilege".
The principle of least privilege, also known as the principle of least authority or the principle of minimal privilege, is a security principle that requires that users, processes, and systems should only be granted the minimum level of access necessary to perform their required tasks.
Running all processes as root or administrator violates this principle because it grants all processes the highest level of access to the system, which means that any process can potentially perform any action on the system. This creates a significant security risk because if a process is compromised or malicious, it can carry out any action on the system without restriction, including accessing, modifying or deleting critical system files, installing malware or accessing sensitive data.
By limiting the privileges of processes and users to the minimum level necessary to perform their required tasks, the principle of least privilege helps to mitigate the risk of unauthorized access, data breaches, and other security threats.
Therefore, it is recommended to follow the principle of least privilege by granting only the minimum required privileges to users, processes, and systems to prevent potential security breaches.
