History of Network Security and Why We Need it.

Updated on January 27, 2016

Why do we need network security? When the idea of network systems and packet distributions began in the 1960s, the idea of hackers and viruses was non-existing. As time and technology advanced it became clear that these threats were becoming more and more common and something needed to be done.

A hacker named Kevin Mitnick, who had been infiltrating companies and their computers for financial gain since 1979, finally served 5 years in prison for wire and computer fraud in 1995. Since then, the Information Technology market has been filling up with network management and network security software to patch and prevent breeches. Some of the most popular Network Management Configuration softwares that help deter hackers and viruses are:

McAfee Preventsys Risk Analyzer

GFI LanGuard


My Digital Shield Network Management Configuration

Spiceworks IT Desktop

But even Kevin Mitnick might still be able to hack his way through a Network Security Software. So, Mitnick had a better idea after he got out of jail. He decided to create his own network security consulting company and started using his hacking skills to point out flaws in business infrastructures and make them better.


Another hacker, named Jonathan James, was able to hack into NASA and downloaded enough information to understand how the International Space Station worked. This caused NASA to shut down for weeks to find the breech and cost them thousands.

Albert Gonzalez used his hacking skills to steal millions of credit card numbers, insurance cards, and birth certificates and sold them online for millions of dollars.

Hacking goes way back to 1903 when Nevil Maskelyne changed the Morse code for Guglielmo Marconi’s secure wireless telegraphy technology during a demonstration to make it appear as though the invention was not secure.

So, these are just some of the reasons why Network Security has become so important in our day-to-day life. Network Security is there to protect us from identity theft, stolen credit card numbers, and much more


Since the beginning of the Internet, anyone who got on it could potentially do some harm and after Mitnick’s crimes, Network Security has come a long way.

Network Security started as early as 1930 when Alan Turing broke the code for the Enigma Machine. In the 1960s the Department of Defense created the ARPANet, which would eventually become available to the public as the Internet in the 1990s. In the 1980s hacker related crimes started popping up all over the place so the Government created the Computer Fraud and Abuse Act of 1986 and the Computer Emergency Response Team to help avoid hackers and inform users of potential threats. Now, there are as much as 255 security breaches in one given day.

To become more secure, businesses began using an Intranet to exchange electronic information within the business. This allowed the business information to be isolated away from the public Internet. There is even a group called Internet Engineering Task Force (IETF) that helped build the security mechanisms that are layered into IPv4 and IPv6. However, some attacks cannot be prevented by these mechanisms. So, companies are forced to add extra security to their networks, such as a network security software and network anti-virus.

With all of the hackers and threats out there today even a personal computer should have security software. Doing any kind of business these days should always come equipped with some security.
