Security and VOIP


Why and How to Secure It

Internet telecommunications via Voice over IP is a groundbreaking technology that saves companies thousands if not millions of dollars each year in their telecom costs. It is the ideal system for enterprises involved in telemarketing campaigns and Business Operation providers offering marketing services. Unfortunately, a VoIP network is vulnerable to security attacks like your data network. And the thousands of dollars saved by implementing the network is reduced to nothing if security issues are not considered. VoIP compromised security poses as an internal and external threat to sensitive data including financial and client/customer confidential information, causing an effect on the efficiency of the network and quality of calls that concludes in increased dropped calls and poor quality of conversation. You must be as vigilant in your VoIP network security as you are with your data network.

VoIP networking and server infrastructure presents security vulnerabilities that can impact the organization adversely from old hacking tricks to new threats especially designed for VoIP networks. You and your IT department’s capability to connect the network and security data is important in the prevention of attacks on the VoIP execution. Setting up a monitoring and management system that integrates flow-based system behavior analysis and event correlation to resolve security issues are the foundation for tracking down and preventing VoIP network threats.

Segmentation for Efficient VoIP Performance and Security

Separating VoIP networks from the rest of your networks and their activities is the number one advice of VoIP providers. This method has two benefits for VoIP execution. One, it ensures network traffic goes through the right channels including security devices and network paths. Two, setting up a dedicated segment solely for VoIP traffic secures dedicated bandwidth that the network needs to work properly. VoIP is bandwidth sensitive and dedicating bandwidth prevents sudden drops which causes packet loss and delays that results to dropped calls and poor call quality. Separating the VoIP is critical to ensure the quality of Internet telephony. Business applications such as peer-to-peer and databases can affect required band frequencies leading to poor call quality.

Establishing the VoIP Infrastructure as a Distinct Network

Establishing the VoIP network system including software and hardware infrastructure as distinct from other networks enables monitoring and tracking of network flow that helps distinguish the root of VoIP traffic. Defining the network as different or separate from the rest of the existing networks allows:

  • You to sieve and search on VoIP traffic flow and related security logs that can help in solving your network’s technical and security problems.
  • Observe and learn from the behavioral traffic flow of the network to establish the right policies for security issues.
  • Operation and executive level reports to be easily generated on VoIP security and network utilization.

Neutralize the Two Most Frequent Attacks in the VoIP System Through Diligent Network Analysis

Track down and easily counteract DoS attacks on your IP PBX via Network Behavior Analysis. Dedicating a separate and distinct network for VoIP enables you to make network behavior and traffic analysis to easily track down anomalies – Toll Fraud and DoS Attacks. DoS attacks come from assaulting the IP PBX with maximum volume of concurrent voice signaling requests. And when the PBX can’t catch up with the requests it shuts down access, including that of authorized users to the VoIP services. The end result is loss in revenue from lost time, opportunity and productivity. By diligently generating Network Behavior Analysis, these attacks can be detected before they wreak havoc into the system.

Securing your VoIP network by segregating it from other networks and establishing it as a distinct infrastructure offers security solutions that will prevent disruption in productivity and keep the integrity/quality of Internet telephony in check. Securing your VoIP ensures all your data including sensitive financial information and confidential customer details are protected from hackers, and internal or external security threats.
