The problem is that people forget there is no reason to put anything you would not want stolen on line. There is just some things you should just do the old school way. We should mix the 40's way and how we do things now. That would make the internet secure.
I don't think the internet will ever be 100% secure. There will always be people out there trying to hack it, or figure out a new way to get into stuff they aren't supposed to. The best thing is to make sure your imprint online is minimal and to change passwords and look into your stuff on a regular basis.
As technology advances, there will always be people looking to exploit loopholes in order to profit from them. We have seen this in a number of high-profile hacking incidents in the past several years. These hackers devote their time to this pursuit and it would be very unlikely that a system that was hackerproof could be installed worldwide.
The internet will never be totally secure because it grows so fast and people are always finding was to get into where they should not. All that can be done is to try to stay one step ahead of hackers who would do harm. A balance has to be reached between security and availability.
Over the last few years, the numerous data hacks and leaks have made clear that nearly all information hosted over the Internet is liable to be hacked and stolen, regardless of its importance or sensitivity. The fact is, maintaining secure networks and computers requires a great deal of vigilance and effort, and few if any companies are willing to invest these kinds of resources, up until they are hacked, and then it is too late.
