Dear All,
As per my project requirement i need to implement lots of security part according to the requirement. Yet am fresh to security part on linux.

So kindly help me and give me a clear idea about the security part

what is difference between /etc/security and
/etc/pam.d and how it can be used based on security.

Thanks in advance..

Regards,
Subash.

/etc/pam.d contains configuration files for various system daemons and management executables. Whenever a (PAM-aware) process tries to authenticate a user, start a session, create an account, or manage passwords, PAM wil look in /etc/pam.d for a file with the same name as that process. That file must contain instructions as to which PAM modules should be invoked to perform the action in question. If no such file exist, PAM will use the /etc/pam.d/other file if it exists.

The PAM modules can be found in /lib/security or /lib64/security (or perhaps /usr/lib/security or /usr/lib64/security, depending on your distribution). They all have man pages.

The files in /etc/security contains configuration files (and in some cases subdirectories) for various PAM modules. These files, too, have man pages.
