Security risks will always loom in the IT industry and, with 50% of mobile traffic to be carried by VoIP technology by 2019, the rise in cyber-attacks is inevitable. While tech experts have noted an increase in VoIP system hacks, a potentially unnerving scenario for service providers and VoIP users, there are preventative steps that can be taken. So, it’s not all doom and gloom, and a variety of countermeasures can help prevent these attacks and ensure system safety.

The future of a smooth running telecommunication network will be safeguarded by a multi-layered approach to security. This will significantly reduce the vulnerability of VoIP systems against cyber-attacks. While no measure can totally eliminate hackers disrupting VoIP lines, maintaining a tight protection protocol with the right software will be the key to keeping attackers out.

The variety of threats against VoIP include: various types of social identity fraud, such as rights and content where hackers can use captured account information to impersonate a user; eavesdropping between two or more endpoints; and interception is also a rising threat with full access between two signals being linked. Premium rate service fraud another major threat, is when attackers make subscribers call premium rate numbers. Premium rate service fraud is a growing threat and has become one of the more prevalent types of cyber-attacks, contributing about 4.73 billion dollars in losses globally. VoIP softphone applications are also vulnerable to malicious code attacks against data and voice applications.

Managing disruptions on VoIP services is crucial for smooth sailing business for vendors. Common firewalls and antivirus software will help and should be an integral part of security, filtering out abnormal signals and RTP packets. However, the next level of your security integration should be based on hardening servers and employing anti-tampering and host intrusion detection to improve your overall system safety.

To deter major cyber-attacks on VoIP routes, strong authentication systems are necessary. VoIP components need to know exactly the different signals there communicating with. And, with physical security schemes restricting areas, access control, locks, guard, physical attacks will be kept at bay.

Below is the top 9 security guidelines for VoIP networks.

  1.      Develop appropriate network architecture.
  2.      Use VoIP-ready firewalls and other appropriate protection.
  3.      Do not use a softphone system.
  4.      Tighten physical security control.
  5.      Implement power back up system.
  6.      Maintain current patch levels.
  7.      Install anti-virus system and update it regularly.
  8.      Apply encryption selectively.
  9.    Implement stringent authorization policies to prevent unauthorized access to VoIP service and account data.

Network segmentation is another method in the the multi-layered security of VoIP networks. For example, SIP phones can have their own network line, which helps restrict VoIP to permitted devices. By giving higher priority to VoIP, you segment networks and limit further movement up the VoIP line for hackers.

Improving your VoIP security will greatly reduce the chance of cyber-attacks. With the rise in security risks in VoIP networks, the last thing you want is to be spending time and money fixing VoIP problems. There are a number of measures that can enhance your security levels, but with the stringent protocols mentioned above you’ll deter major physical attacks.
