Threats To The VOIP Based Small Business Phone Systems And Their Solutions

By smallbusinessphonesystem.com.au@gmail.com : A how to tutorial about small business phone systems, IP phone, Business with step by step guide from smallbusinessphonesystem.com.au@gmail.com.

The VOIP based small business phone systems have many advantages over the other, more traditional ones. These make the telephonic communication more manageable. The people usually see at the bright side of the IP phone systems like the quality of sound, latency and the interoperability. They conveniently overlook the security aspect. Herein are listed some of the security challenges to these service systems:

1.Service Theft: This is a possibility if the specialized encryption techniques and Public Key Infrastructure are not used for the authentication process. If these are not used, then there is a danger that the authentication credentials can be falsified. Most of the modern IP services providers make use of the Ethernet Media Access Control addresses which can be easily forged.

2.Impersonation: This is yet another way in which the IP based small business phone system can be hijacked. Some element within the network can be breached to provide for the hacking of the calls. You calls will be directed to some other destination and your own destinations can be reached by the hacker pretending to be you only.


3.Eavesdropping: It refers to the listening of the telephonic communication made on the VOIP network. This is not difficult since the telephony call or the sessions details can be retrieved by the eavesdropper along with the speech packet details.


Message Integrity: One of the important features of the IP phonesystems is that these are used for the IM as well as SMS messages.

4.The attackers can alter the conversations or messages. They can also put in their own messages or speech, delay the reception and do other problematic things
The other threats like the virus attack, spam and denial of service attacks are known to computer systems for a long time. The same threats are also there for the small business phone system based on IP technology. So, how can these threats can be done away with or minimized? Some of the security features that can be incorporated are:

1.Use a number of software and applications to include access control lists.

2.Impersonation threat can be reduced by the use of the intelligent network switches rather than hubs.

3.Encrypting the different layers, for example, the network, the transport or the application layer can also enhance the security of the packets during the transmission.

4.The DOS attack can be prevented by making use of the protocol tuning between the end points and the different applications being used for the software. These can also be prevented by blocking the port with changes to the switch.

5.Inclusion of the fast failover session control service in the communication networks to make a quick backup of the server resources.

Since the VOIP based :-small business phone systems are seeing increasing use and adaptability, there is lesser focus on the security requirements of these systems. But, this perspective will change soon and there will be a need to prevent these against all types of dangers.
