Let's go a decade back, at that time also computers were used but very less in comparison with today. And as same many programmers have lifted many security loops on their programs. Hope you remind about the internet's biggest vulnerability "HeartBleed". About HeartBleed it was said that the vulnerability resides for 15 years on the software. So there may be a chance of more bugs on different products.
Here I am posting a [Infograph] (posted by Dell) which is very much informative, and give a lot of information about the history of bugs and computer threats. The infographic covers all the major threats that was been occur till yet.
We like to hear from our readers about the above infographics and ask them to share their reviews on this.
