Voice Over IP: Is It Risk-Free? Essay

Of the grounds suggested for implementing VoIP. the point that appears to be most important is economic ground of salvaging money. In the instance of private webs. finishing calls over a packet-switched web allows an organisation to avoid paying expensive long distance telephone charges. a map known as toll beltway. While in theory utilizing VoIP makes the voice transmittal appear to be “free” since it is going on the Internet. the world is that the capacity of the web and the dependability of the Internet are non sufficient at this clip to vouch the quality of service that most people expect on voice transmittals.

There are benefits in sharing a individual web. traveling from proprietary voice system to standards-based waiters. and the flexibleness to link about anyplace in the universe through an bing web. Obviously. VoIP is non immune to the dangers normally related with IP webs. Proposed solutions for VoIP security are already in the market. but these solutions must take into history the real-time restraint of voice service and their mechanisms should turn to possible onslaughts and operating expense associated with it.

Although VoIP engineering have made the larceny of telecommunications services less moneymaking. VoIP engineering has opened the door to new sorts of offenses. The U. S. Department of Justice has gone on record as being concerned about the fast growing of VoIP communications services because they make surveillance and wiretapping hard and can ease “drug trafficking. organized offense and terrorism” ( Keegan. 24 September 1994 ) .

Laura Parsky. a deputy helper lawyer general in the U. S. Department of Justice. told research workers at a June 2004 Senate hearing that “ [ I ] f legal loopholes allow felons to utilize new engineerings to avoid jurisprudence enforcement sensing. they would utilize these engineerings to organize terrorist onslaughts. to sell drugs throughout the United States and to go through along national security secrets to our enemies. ” The hearing was held to see alterations to the proposed VoIP Regulatory Freedom Act. which. if passed. might necessitate telecommunications suppliers to construct “back doors” into VoIP webs that would let for court-ordered wiretaps to be successfully enforced.

In fact. the cardinal paradigm shift—voice as merely another service running on a shared. IP-based infrastructure—calls into inquiry our basic outlooks of the security of voice.

The characteristics of the engineering employed frequently subtly. or non so subtly. colour security outlooks and concerns. For illustration. the authoritative onslaught on confidentiality prior to the electronic age was “steaming” an envelope unfastened ; hazards were to be expected and countermeasures were developed with this peculiarly in head. But this onslaught and its countermeasures are clearly irrelevant to a telephone conversation.
