Let me state right away that I realize it's impossible to bulletproof your website from potential threats. But lately, hackers are getting in because the companies' website development failed to implement basic safety measures and correct the bugs that allowed the breach. The most recent example is T-mobile where all the hacker needed was user's phone number and T-mobile should have found the bug by monitoring for abuse. Another more critical example is Experian who knew about the issue, but allowed it to go on and on. Bugs are bound to happen and hackers are going to hack. What are the best practices that website developers and owners should implement?
