Service and the Security implication of VOIP Dissertation

Service and the Security implication of VOIP - Dissertation Example The use and importance of telecommunication in business cannot be overstressed. In some industries, it is even their source if not the most important infrastructure that drives the business processes. However, in order to use the technology efficiently and effectively, its limitations and security has to be assessed and determined. The anonymity of the internet provides an added complexity to the challenge since the prosecution and detection of perpetuators is not only hard but the detection of an actual eavesdropping is already hard in itself. This dissertation will provide the best infrastructure that is both resilient and redundant that will provide the basic security to basic security threats. As proof of concept this dissertation will also demonstrate how an actual VoIP system can be set-up and used, this dissertation has also confirmed how an actual attack on the security can be done and its potential effect on the user. This dissertation also provided a technical strategy on h ow to remediate the security vulnerabilities. However, as any technical security strategy goes, there will always be a hacker that is better at overcoming the best and the latest security system. A determined hacker will always find a way to overcome any security system thrown in front of him thus this dissertation will provide recommendation that will protect businesses from falling prey to opportunistic and disreputable shady characters.
