Securing VoIP
Improve the efficiency of your networks with Stonegate
For businesses, IP telephony is becoming an important asset as it enables greater
profitability and remarkably boosts business performance and effectiveness.
This means lower costs of ownership through having just one combined IT/telephony network and
by enabling higher employee productivity.
Moreover, it protects investments made in the current network by enabling new services over
the existing IT network.
Although IP telephony offers numerous new opportunities, it also creates severe security
threats. It faces the same challenges and threats that are more commonly linked with the Internet.
Viruses, worms, trojan horses, Denial-of-Service (DoS) attacks, and hijacking are all possible
threats on the VoIP network. Voice traffic can now be attacked, hacked, intercepted, re-routed, and
degraded just like any data packet on the data network.
The convergence of voice, data and video traffic to a single network also means that the
amount of traffic in the IP networks, as well as the criticality of traffic, increases the
complexity of networks.
