Secure Design with Exploit Infusion

User passwords were first introduced to allow time sharing on large mainframes. Mainframes at the time were large systems within a controlled environment. Passwords were stored in plain text file with no perceived need to secure user passwords. The first documented password breach occurred when a user wanted to gain additional time on a mainframe than the allotted four hours limit. The user simply printed the password file giving birth to the first documented password breach. Developers are continuing to develop new ways to protect user passwords.
