With the proper configuration, policies, and services, we can assure ourselves that our conversation has been secured.
For the most part, I love my job. I love sifting through Wireshark traces trying to find needles in SIP haystacks. I get excited learning about new IP communications products, and my heart practically skips a beat when I read about another SIP service climbing out of its physical shell and going virtual.
The best part of my job, however, is when I get to walk away from my PC, IP telephones, and LAN analyzers to meet with the users of unified communications technology. It doesn’t matter if it’s a regional user’s group or a series of one-on-one meetings with IT professionals. I love solving problems and helping people understand the technology that is near and dear to my heart.
With that in mind, today I thought I’d delve into one of the session topics I will be speaking on at the upcoming International Avaya User’s Group’s (IAUG) “Converge” conference in Denver, where I hope to help users solve the problem of securing a SIP network.Building a Secure SIP Network
When you think about security in terms of SIP and VoIP, you need to consider four different areas:
- First, you want to protect the SIP signaling.
- You need to protect the media stream.
- You need to ensure that people are who they say they are.
- Lastly, you need to create a secure network edge that prevents the bad guys from sneaking into your business and compromising your VoIP network.
