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 unauthorized and expensive calls as well as all sort of phone related illegal activities. Quite often, the targeted organizations have no idea that a breach has occurred. VoIP security means the implementation of strategies and mechanisms such as VPN and SBC (Session Border Controllers) to defend your system from hackers. They both hide your network topology. SBC also offer an active protection by detecting abnormal behavior and malicious patterns and prevent intrusions by blocking the source of attack.
