Various strategies implemented within an IT infrastructure to protect Voice over Internet Protocol (VoIP) communication services from potential network threats. These preventative tactics offer security and added performance to a company or VoIP provider when business-critical voice communications are transmitted over a VoIP network.
Organizations using VoIP communications need to understand that while the service is convenient and makes efficient use of under-utilized network resources, without proper security measures in place problems can arise. VoIP network security works to preserve optimal communication performance within a business's network by preventing possible threats such as viruses, Denial of Service (DoS) attacks and Distributed Denial of Service (DDoS) attacks. When a VoIP network encounters harmful traffic, it is deprived of the vital resources and services it requires to provide efficient communications. This can result in transmissions that degrade voice quality, making it unintelligible and rendering the system useless. Fixing these problems can cost businesses both time and money. With these reasons, it is easy to see why implementing proper VoIP network security is so important. With an efficient communications security strategy in place, companies can improve VoIP functionality and drive overall business performance.
