How Does Linux Passwd Use SUID For Secure Password Changes? Ever wondered how Linux allows regular users to change their passwords securely without granting full root access? In this video, we explain how the passwd command uses special permissions to protect sensitive system files during password updates. We'll cover how the SUID (Set User ID) bit works, enabling the passwd program to temporarily run with elevated privileges. You’ll learn why this setup is essential for maintaining system security while allowing users to manage their own passwords easily. We’ll also discuss how Linux carefully manages privilege escalation and de-escalation, ensuring that the system remains safe from potential exploits. Additionally, we’ll explore how the permissions on the passwd executable indicate the presence of the SUID bit and why programs with such attributes need to be written with extra caution. Understanding this process helps demystify how Linux balances security and usability, making system management more efficient and safer for everyone. Whether you're a beginner or an experienced user, grasping the role of SUID in password management is key to understanding Linux security mechanisms.
