What is VoIP Security?
VoIP systems are vulnerable to many of the same threats that target other forms of computing technology: malware, network breaches, DDoS attacks, and even phishing attempts. Once compromised, your system can be used to make unauthorised, expensive calls and for other phone-related illegal activities. Quite often, the targeted organisations have no idea that a breach has occurred. Implementing VoIP Security provides strategies and mechanisms such as VPN and SBC (Session Border Controller) to defend your system from hackers. They both hide your network topology. SBC also offers active protection by detecting abnormal behavior and malicious patterns and prevents intrusions by blocking the source of attack.
