Explain what are the External Threats

External security threats are the most problematic ones. Till date the greatest threat was the virus menace. Now, with the sophisticated technology, a number of new threats have developed. It becomes difficult to know when an outsider will attempt to hack the systems or who the intruder maybe. There are a number of examples in the past, the recent being hacking of the government's servers by certain terrorists and foreign nationals.

Some people go to great extremes to gain access to the systems and information. If the Intranet is connected with the outside world via the Internet, it will discover a whole new set of potential problems and subject to a number of attacks. Internal & external threats are shown by Figure1, where one Internal person in Intranet is trying to break the Internal security and one external person is also trying to enter in the Intranet of the organisation.
