An article that goes over checking the PAM framework, harden the basic services that we expect to authenticate to, and look at new PAM modules that might make our systems more secure.First make sure that /etc/pam.conf doesn't exist unless this is an old system running an older version of PAM.
Next, make sure that /etc/pam.d exists, and contains PAM configuration files.
The first user to log in at the console of a Linux box can get ownership of many hardware devices, depending on how PAM is configured. Traditionally, Unix systems let the superuser (root) own the hardware, but to make it easy for desktop users to access devices such as sound cards, CD drives, and the like, the first console user can be set up to have ownership of these devices. Ownership reverts to root when the console user logs out. The device list is in /etc/security/console.perms, and ownership is changed by the PAM module pam_console.so. Only registered users can write comments. Please login or register. Powered by AkoComment 1.0 beta 2! |
