Access was controlled and maintained with the use of ID’s, keys and restricting access to only authorized staff, as measures against theft of info and equipment. As time passed and greater levels of security were needed, many technological and complex systems were developed. 1960’s- As more mainframes were put into use during the war, it became obvious that a more convenient method of communication between computer centers was needed. As a result, Larry Roberts, hailed as the internet’s founder, designed the ARPANET(Advanced Research Projects Agency Network), which is called the internet’s predecessor. 1970’s/80’s- While ARPANET grew in popularity, and use during this time, so did the likelihood of it being wrongly used. Robert M. Metcalfe pointed out many flaws with its security features, such as password vulnerability, lack of authorization for system access and zero safety procedures for dial up connections.This lack of security was addressed by the Department of Defence in 1967 and was placed in researchers hands to develop security measures beyond merely safeguarding physical locations. 1990’s- The need for networks to be connected became more and more necessary as computers became more common. The internet was born from this. Originally strictly government property, it was made available to the public, allowing practically all computers with access to a phone line to connect. In the internet’s early days, security in any form or mail encryption or authentication wasn’t seen as
