An introduction to network security management.
Network security management is equivalent to managing a computerised network against security threads, unauthorised access, misuse and modifications. In today’s interconnected society the protection of confidential data, business continuity, availability and integrity became of great importance to any organisation. This document aims to provide you with a better understanding of network security in terms of history, network security policies, prevention systems and detection systems available on the market that may help secure your computer network.
The history of network security management.
After a lot of research and designs, in 1969 the first interconnected network was a fact also known under the name ARPANET1. The ARPANET is the predecessor of the currently known Internet. Even before the Internet was introduced, the first computer virus was detected on the ARPANET in 19712 and was known as ‘The Creeper’, which was not much later removed by the removal tool known as ‘The Reaper’.
We can conclude the introduction to network security started here, in 1971. In the years after, the technology of internetworking been through an evolution and is still changing every day. Today’s security threads to a network are not limited to viruses.
Today’s security threats.
Today’s security threats are much more sophisticated and harder to detect than ever before. Especially with the upcoming collaboration platforms such as cloud computing, social networking, mobile payments we are more sensible and exposed to new security threats. Ever since we started using these technologies, social engineering became a clear definition. “Social engineering is generally a hacker’s clever manipulation of the natural human tendency to trust”. .
An example of social engineering may be a person who calls your company and pretends to be a travel insurance company that provides travel
