When the internet was first launched on a mass scale back in the late 80s, it is understandable that the technology industry got more than a little excited – the way we communicate and thus the entire world around us was being changed for good. But there was one problem: the internet was not designed with security in mind.
It was not long of course, before criminal minded people took advantage of this oversight and the first internet virus was circulated in 1988. Thankfully the security industry was hot on their tails, launching the first firewall in 1989. And thus began the ongoing battle between security experts and cyber hackers that has continued over the last 25 years.
Sectors that were deemed particularly vulnerable to network infiltration, such as the military and financial industry were the first to set up their defences, but the true threat of cybercrime was soon realised. These early firewalls relied on basic packet filtering using a simple rule: depending on where the packet was coming from and travelling to it was either allowed to pass or blocked at the firewall.
