أمن الشبكات الحاسوبية في الاتصالات المرئية

This research studies video over internet protocols, which are becoming more common. More networks and legacy systems are being connected to public networks, allowing organizations to reduce costs and improve their offerings while allowing users to enjoy a variety of new and advanced services. The research also studies security as an important consideration when implementing VOIP because each element in the infrastructure is accessible on the network like any computer and can be attacked or used as a launching point for deeper internetwork and inside-the-organization attacks. I presented a vpn solution which traverses existing infrastructures and can realize connectivity without requiring firewalls and/or NAT devices to be modified even for new protocols or revisions.
