Pointer to an article on Protecting VoIP
Colleague Dave Piscatello has a very nice article on VoIP security that's up on Network World
Dave does a nice job of delineating some base threats of identity and information theft and toll fraud. These threats aren't new. They carry from the traditional telephone network. He clearly articulates the SPAM problem, and the roo of that problem, which is really spyware (or other malware).How to protect your VoIP network
Beware of phreakers, fraudsters, sniffers, RATS, SPIT, men in the middle, broadcast storms, Wi-Fi jamming.
VoIP has finally arrived as a mainstream application. IP PBX equipment sales topped $1 billion in 2005, for the first time outpacing traditional TDM PBXs, according to Dell' Oro Group.
In fact, analysts predict that IP PBXs will account for more than 90% of the market by 2009. Before you deploy VoIP, however, you need to be aware of the security risks and the countermeasures that you can take.
Security is important in every context, but especially when you're replacing the world's oldest, largest and most resilient and available communications network. While no individual security measure will eliminate attacks against VoIP deployments entirely, a layered approach can meaningfully reduce the probability that attacks will succeed.
I think Dave did a very nice job of highlighting the keys around risk assessment and outlining some of the primary countermeasures needed to protect VoIP services.
If you're a manager considering VoIP deployment, or a technical person trying to articulate the security needs to support VoIP to your management team, this is a great short article that summarizes the key issues quite nicely.
