Formato: PDF
In the near future, cable networks will carry low-latency voice and video signals with quality rivaling or surpassing that of the Public Switched Telephone Network (PSTN). Along with the need for quality-of-service (QoS) assurance, voice- and video-over-IP services must also be protected from eavesdropping and theft of service. The PacketCable 1.2 Security Specification provides a framework for securing voice/video transmissions over cable networks. This Technology Guide addresses security in data over cable standards, summarizing the latest technical specifications outlined by CableLabs, a consortium of cable industry vendors and service providers, and introducing the security specifications outlined within DOCSIS.

Best practices for SIP NAT traversal

Traversing NAT (Network Address Translation) is one of the issues that hinder SIP communications. Some background about the problem: With an ideal Internet, all devices would be able to communicate end to end without any intermediaries except routers. This assumes each device has a routable IP address, a public reachable Internet identity. In reality, today many of the devices connected on the Internet are using a NAT function present in the border router. While this stops the Internet to initiate connections to the device (bad for IP telephony or other forms of peer-to-peer communications), it also protects the users against malicious attacks. Using NAT, one may also connect multiple devices to the Internet by only using one public IP address. So NAT has both advantages and disadvantages.
Why doesn’t SIP work by default behind NAT? The reason is that many of the communication parameters in SIP are transmitted within the SIP message; such parameters include the IP and port numbers used for signaling and media. A SIP device behind NAT does not know much about how it will be seen from the Internet, it only knows its own IP address and the ports where the SIP application runs. Once communication with the Internet starts, the NAT device translates the private IP:port combination of the SIP device connected on the private NAT interface to a temporary mapping of a public IP:port on the interface connected to the Internet.

With the increasing deployment of IP telephony systems, attacks against IT systems that threaten business operations and the privacy of corporate and personal data no longer have an impact only on the data world. Coverage of security issues tends to focus on the type of attack and the estimated loss - be it immediate financial damage, negative impact on a company's reputation or loss of customer confidence. To protect against the threats, Avaya has devised its Unified Communication Center (UCC) that provides mobile employees with speech access to relevant information on a converged infrastructure using multiple layers of security.

In the past, corporate adoption of interactive voice and video technologies over IP has fallen short of analyst expectations. The adoption of this technology has suffered from the complexities of implementing the H.323 standard, no appropriate network infrastructure, conflicting security applications, and limited management platforms for VOIP and video technologies.
This paper summarizes the network infrastructure requirements for voice and video, focusing on issues found most frequently where the public Internet and private IP networks meet. It explores numerous solutions, pointing out their shortcomings and the need for a set of building blocks that address these issues without requiring network reconfiguration or exposing corporate assets to non-secure network conditions.

The information presented in this document is technical in nature but straightforward and easy to understand. The vulnerabilities in VoIP are clearly identified and illustrated for non-technical individuals. Presenting this information in a public forum, such as this paper, does not jeopardize the security of existing VoIP systems. Most of the information presented here is already known by skilled attackers. This open discussion of vulnerabilities is intended to prompt vendors and the VoIP user community to be more diligent about their security. In the end, sharing this information will allow for a more secure and trusted environment.

Most of the benefits of IP telephony are due to architecture-enabled transformation of telephony. Such transformation is enabled by implementing telephony and other convergence applications in location independent application servers. These servers can be deployed anywhere on the IP network as long as performance requirements are satisfied and connectivity exists between the servers and their clients (other applications and end-user devices).
