Voip Security

Conference calls make it possible to speak to multiple people simultaneously. This is extremely useful when the people required to be involved in the call are based all around the country.

When it comes to VoIP phone systems, the "Vo" part refers to voice over, and the IP part stands for having your phone calls routed over the Internet. Many business owners have opted for these phone systems because they are cheaper than having numerous and separate phones in the office. You do not have to use the network or telephone service to make phone calls, which lowers the overall cost. At the same time, there are advantages of using IP technology for telecommunication.

PSTN is the world 's collection of interconnected voice oriented public telephone networks, both commercial and government-owned. It 's also referred to as the Plain Old Telephone Service (POTS) CITATION Lin05 \l 1033 (Lin, 2005).

The California plant appears to have a possible upgrade from what was most likely a similar structure to the New Jersey Plant to a Nortex Digital Phone System with VoIP. This system allows the California Plant to leverage the existing network used to communicate data across the Ethernet (and ultimately across the Internet) to additionally manage voice communications. The VoIP could additionally (although not documented as such) utilize a Public Switch Telephone Network (PSTN) gateway to send digital signals (voice) allowing the company to make local calls outside of the LATA where the plants reside.

They would only need a microphone, speakers, or a telephone that is VOIP enabled. Even though there are up-front cost involved with the IP phone system, it will reduced the communication and network management cost by 20 to 30 percent. This is a chart example of how VOIP works.

The Department of Defense networked systems are large. According to one article in the National Defense Magazine the total number is 15,000 (Erwin, 2013). With this amount of networks to defend, it is remarkable to not hear of more intrusions. However, though this argument is focused for those whom are echelons above the battalion and brigade level, network consolidation should be moved at a much faster pace. Currently there are over five separate networks being utilized by the Army alone. Each network is managed differently and by different security managers. Without proper communication, an attack on one network might go unnoticed by the security managers on other networks. Though convergence is underway, the 9th Mission Support Command took a slight step backwards when the command brought the Army Reserve Network online in 2015, after spending the past six years utilizing the United States Pacific Command’s network.

It is known that SIP has no security system, which means it has no authentication techniques which makes it more exposed to getting attacked. The need of having such a technique becomes more crucial nowadays. A practical method to sort out this issue is using an encryption scheme that helps SIP traffic to be encrypted. Another issue of SIP authentication is having no integrity level. This issue could be addressed by using an integrity mechanism such as TLS (transport layer security). TLS provides high level of secured traffic by using key-management, which is very secured [security analysis].

The Department of Defense (DoD) is America 's oldest and largest government agency, with military traces dating way back to pre-Revolutionary times. The Department of Defense has since grown and evolved with the nation, hence becoming the national’s largest employer with over 1.4 million active duty soldiers, 1.1 million National Guard and Reserve forces, and 718,000 civilian personnel. With such a huge organization does come with a huge network, and security infrastructure network, and the burden to protect the information transferred or stored on that network. This means information is a strategic asset to the Department of Defense; it’s therefor the goal of this security policy to provide guidelines of implementing

The U.S. Army is witting in soldier’s trafficking of sensitive but unclassified (SBU) information across unsecured networks, and it should better manage this information flow. This data, whether it accountability data, location services, or speech communications, is most often trafficked across personal mobile devices, possessed by soldiers, and useful in the accomplishment of their daily duties. These mobile devices also accompany the soldier to work, where not specifically restricted. Mobile devices, such as cellular telephones and tablet computers can, and do, transfer information outside of the Army network. They are vulnerable because they rely on unsecured networks to communicate. It would be more advantageous to the soldier, and more

I would also request that active monitoring of the VoIP network be assigned to a member of the IT team to ensure no unauthorized devices were linked to the network. Additionally, this IT member would be required to run intrusion and antimalware detection software on the system and ensure that it is maintained at the highest state of readiness. This involves running checks of the system constantly to ensure no unauthorized devices have been linked into the system, verification of the integrity of the VoIP tunnel and monitoring the system to verify connectivity, and software integrity. The easiest layer to add for mitigating risk over the VoIP network is the users themselves. Sure we have given the users access Tokens allowing them to choose a complex password that only they know, but we also must educate the users. Through education we can teach the

The act of using voIP over the internet opens the window for many internet attacks and security and protocol issues. Protocol vulnerabilities include numerous attacks all at once, security vulnerabilities, and attacks exploiting private and crucial information. VoIP is a freely opened environment, therefore, there is a large window of opportunity to the hacking world. What this means is that the internet is easily assessable to a multitude of people, some with good intent and some with malicious intent. Because this is made to be so easily accessed, it is easy for a person to act in a criminal manor and disrupt the flow of private conversations. To help eliminate some of these issues SIP has evolved as the signaling protocol to recognize and handle mass media sessions for the internet and its extremities. These vulnerabilities are so severe because attackers can exhaust and misuse available resources, create false responses to malicious requests, or discover more security vulnerabilities.

One of the largest obstacles VoIP needs to overcome is the issue of security. Just taking a look into the email of any person can show why this is the case. Spam is rampant in email and VoIP phones would be subject to the same spam problems. Scripts could be written to call numbers and speak or play the ad on the user’s cell phone. This could wreak havoc without proper laws and measures implemented to prevent this. There is also the issue of hackers gaining access to calls over the Internet. “VoIP devices such as IP phones, Call Manager, Gateways, and Proxy servers inherit the same vulnerabilities of the operating system or firmware they run on top of.” (Intrusion

A simulation model is presented to analyze and evaluate the performance of VoIP based integrated wireless LAN/WAN with taking into account various voice encoding schemes. The network model was simulated using OPNET Modeler software. Different parameters that indicate the QoS like MOS, jitter, end to end delay, traffic send and traffic received are calculated and analyzed in Wireless LAN/WAN scenarios. Depending on this evaluation, Selection codecs G.729A consider the best choice for VoIP.

One important concept to understand about VoIP is that unlike its forefathers (lets call them

30. Providing toll-free numbers to attract and simplify the way customers or prospects reach a business is a great use of marketing dollars. With Hosted VoIP providers, obtaining, managing and reporting toll-free numbers is cost effective and simple.
