Linux PAM Security Administration - The Importance of PAM

The video tutorial explains the importance of Pam in the authentication process. It begins with a traditional Linux authentication method using ETC password and shadow files. The tutorial highlights the challenges of traditional methods, especially with emerging authentication schemes like RSA tokens and biometrics. Pam is introduced as a solution to avoid recompiling applications when new authentication methods are developed, ensuring compatibility and security.
