Have you not read anything? Yes, they had security, but all of your personal info was sent in plain text, unencrypted. And yes, no security is unbreachable, but certain securities are just not worth breaching, as brute forcing (i know this is not the only method) them would take billions of years, even with all our computing power. The fact is, they screwed up by not properly encrypting the info as it was transferred between consoles and servers, end of story.
As to your post about PSN and it's security, are you high? It hasn't been put back up because they screwed up big time, and now even governments agencies are investigating them. They stated they are rebuilding the PSN, meaning, since they screwed up, now they have to secure it the RIGHT WAY. You honestly made no sense by stating that.
