چکیده

In recent years, IP telephone has achieved remarkable progress on the Internet through "low price ", "continuous connection", and "high speed communication band". However, it is not easy to use IP telephone over firewall and NAT because of its restrictions of the communication. We have proposed the system called SoFW (SIP over Firewall) that suppresses the problem. In this paper, detailed functions and its implementation method of SoFW are described.

Securing Voice over Internet Protocol ( Ip ) Networks

Voice over IP (VOIP) the transmis­ sion of voice over traditional packetswitched IP networks is one of the hottest trends in telecommunications. As with any new technology, VOIP introduces both opportunities and security challenges. Lower cost and greater flexibility are among the prom­ ises of VOIP for the enterprise, but security administrators will face signif­ icant issues. Administrators m...

On the Design and Use of Internet Sinks for Network Abuse Monitoring

Monitoring unused or dark IP addresses offers opportunities to significantly improve and expand knowledge of abuse activity without many of the problems associated with typical network intrusion detection and firewall systems. In this paper, we address the problem of designing and deploying a system for monitoring large unused address spaces such as class A telescopes with 16M IP addresses. We ...

Security testing of session initiation protocol implementations

The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...
