These organizations are also highly educated and possess the resources necessary to breach even secure networks, although they would rather focus their efforts on those networks that are just too easy to breach and require little effort or resources. When you look at the types of breaches being realized, you quickly learn that the attacks could have been prevented through some very simple measures. For example, a young man on the West Coast was sentenced just this year for hacking into thousands of computer systems looking for platforms that still had their default passwords intact. He would then scan the systems looking for open ports that could be used for pumping his own traffic, or he would open up ports himself. Armed with the IP addresses of the systems he hacked and reconfigured, he worked with his partner (who actually perpetrated the whole business) to sell routes to legitimate telephone companies at cheap rates. They routed millions of telephone calls through application servers sitting in businesses and universities across the U.S., charging telephone companies for access to their network and pocketing millions in profits. The main perpetrator has fled the country and cannot be found. I bring this incident up as an example of how telephone companies (and in this case even well-established VoIP operators) can be defrauded of millions of dollars by even small operations. The hacker was later quoted as saying how easy it was to break into the computers and systems and change their configurations. What was the most surprising aspect of this That established service providers had deployed VoIP servers without changing the factory default passwords! The most rudimentary security measure had been skipped in these networks. In the many lectures I have done on the topic, I am always amazed at how many people do not change their passwords on a regular basis. But passwords are only one measure. Changing passwords regularly is certainly one way of slowing down hackers and fraudsters, but there are many more measures that should be taken to further protect any SIP network. Why is it then that we know security is important, and yet no one seems to be concerned about it (or at least not concerned enough to implement robust security measures) Security can be very inconvenient not only for the operator, but for the subscriber as well.

There are many different forms of network breaches, but here we will talk about those that occur the most often. In fact, these are the types of attacks that are seen repeatedly not only in VoIP networks, but the Internet as well. The Internet can serve as an excellent model of what could go wrong given its wideopen nature. Nothing can be trusted in today s Internet, and fraud and Denial of Service (DoS) attacks are rampant. Anyone who spends any time following security alerts and law enforcement activities in this area quickly understands the Internet is a risky place to do business unless you are prepared to lose a large portion of profits to fraudsters.

That is not to say that the Internet is a losing proposition; certainly there are many businesses thriving on the Internet. But they are also losing a lot of money from fraud, and they could be making a lot more if they didn t have to deal with security issues. A case in point is the current concerns over Web sites and e-commerce. Certainly there have been numerous reports of sites being compromised, sensitive information being stolen from online sites, and consumers attacked with spam and phishing attacks on a regular basis. Since SIP is a derivative of HTTP and SMTP, both Internet protocols that are exploited on a daily basis, it only makes sense to understand the vulnerabilities these protocols experience today to better understand the potential threats within a SIP implementation. The 3GPP and the IETF are also actively adding new procedures and enhancements to the protocol to further harden the protocol against network attacks. Let s look at the various types of network issues, how they work, and how they impact the network operator and the subscriber. Then we will look at ways in a SIP network to prevent these attacks from happening (or at least some good measures to decrease the probability of their occurring). Understanding how hackers approach a network is important to understanding how attacks begin, and what one should look for. Hackers approach attacks in stages, beginning with probing of the network. Hackers first look for networks with easy access. This means a network with open gateways and platforms with default passwords still in use. They then begin looking for vulnerabilities in those platforms by scanning the platforms. Once a vulnerability is found, it is recorded for later use. Many security breaches can be found at the scanning stage. In fact, you could use this approach on your personal computer to find possible viruses and bots that are scanning ports for open access (this is done through software utilities that provide information regarding the activities on your computer platform). This is the same technique used for network elements. There are distinct characteristics to probing activities that you can look for to determine if there is pre-attack activity going on in the network for example, multiple requests to the same server from the same UA, or maybe many requests from one UA to multiple servers and proxies. Once a vulnerability has been identified and validated, it is used later for a larger attack. It is a combination of vulnerabilities that allows hackers to reach through many different networks, traverse through all of these networks unnoticed, and launch largescale DoS attacks on unsuspecting networks. Here are some common methods used when attacking a SIP-based network.
