The greatest threats of attacks for voice over internet protocol providers and enterprises are those which may impair the quality of the voice, thus ceased to be mentioned the service useless. The easiest way to achieve a deterioration in the quality of the voice through denial of service (DoS) and Distributed Denial of Service attacks (DDoS).
VoIP communication brings another dimension to the security challenges of the introduction of a control (signalling) and content (voice) parallel channels, which together form the business voip phone service. The dependence of these channels on each other dramatically increases the risk that may be damaged, VoIP service, channels, each of them has its own mistakes. It doesn't matter that the error is to exploit, because the attack renders the service useless.
Hosted VoIP PBX services phone calling, how the world communicates, individuals and businesses are embracing the capabilities and the use of the power of the Internet. Despite the voice over IP is a big technological breakthrough, the ip office manager, security is still of great concern, and yet with the suitable measures should be.
Most of the users of the introduction of VoIP these days are primarily concerned about the quality of the voice, latency, and interoperability. However, we should not overlook the security risks that you can crop up when worlds converge voice and data, users and analysts say.
VoIP hackers may have tens of thousands of additional fees
VoIP solutions for small businesses is carried over packet-switched data transmission of voice over the IP network. VoIP network can be considered as another form of data, voice, but use sophisticated compression algorithms ensure the use of voice, optimum bandwidth. As a result, VoIP network are able to carry many more calls than a traditional switched circuit network. Small business voip solutions also enable advanced services, such as unified communications.
Security of transmissions of voice in these networks is not very different from ensuring the transmission of data in an IP network. In the world, private VoIP PBX is replaced by the Branch Office IP telephony-based server running on Windows NT or vendor proprietary operating system. Such a call control boxes, which are used for both the voip call center solutions serving the business and the logging information, are prone to viruses and hackers. Breaking of these servers would result in the loss or compromise of potentially sensitive data. As a result, it is important to properly locked managed voip solutions such as firewalls, placed before the corrected errors and often monitored using intrusion detection systems.
The University of Houston went a step further and made sure that his call to the administrator and his whole VoIP network are not directly accessible from the Internet. The school has its branch office IP phone to a different domain than its other servers and Administration has limited access to servers.
VoIP gateway technologies are also a potential weak spot. VoIP for businesses, it is used externally, data packets from the gateway technology transfer network IP voice before it is sent over the public switched telephone network. When VoIP is used internally, the gateway to route the packetized data essentially voice between the source and destination.
Here the concern is that these gateways can be hacked into by attackers to free small business pbx phone calls. The trick to this is with strict access control lists and make sure that the gateway is configured in such a way that only the people on this list is enabled and VoIP calls.
As in traditional telephony, eavesdropping on your concern for organizations using the VoIP-and the consequences may be greater. Because voice travels in packets over a data network, hackers can use data analysis and other hack tools, how to identify, modify, store, and play voice traffic through the network.
Finally, it is important to bear in mind that securing the VoIP infrastructure includes anything that is drastically different from those corporations have always protect their data. In short, there are several simple things any company can take to protect their voip call plans and VoIP network, both the Department and the isolation of voice transmissions on virtual LAN is one way to mitigate the risk of unauthorized access. Second, using access lists that define exactly and who is entitled to access to the network will be eradicated by external threats. Finally, you should use the encryption of sensitive data, adds another layer to your secure communications.
