Should You Be Concerned About VoIP Security?
VoIP has been praised for a very long time for all the benefits it brings to businesses. Cost savings, expanded reach, easier communications – and more. But one thing that always has remained a barrier for adoption has been the worry over security. When the technology was still in its infancy this worry about whether or not it was secure or OK to let your communications pass through an Internet connection was viable. It wasn’t something many were doing yet. The internet and the technologies that make it function weren’t as reputable and respected as they are today. But now – decades later – is security still a concern when it comes to using VoIP for business communications?
Sadly, the answer is yes. That’s because no matter how sophisticated and advanced technologies are becoming – so too are the hackers and those with malicious intent working to understand and exploit the networks and systems.
The latest warning comes from Fatih Ozavci, a managing consultant at Context Information Security who told attendees at the recent Black Hat USA event that VoIP wars are a real possibility if businesses don’t take the right steps to learn about technologies and stay on the defense.
ComputerWeekly detailed some of the warnings discussed during his presentation titled, “VoIP Wars: The Phreakers Awaken.”
Everything from botnets, malware distribution, vishing, denial of service attacks and toll fraud are very real possibilities once vulnerabilities are exploited - so this is nothing to turn a blind eye to.
“By exploiting these vulnerabilities, attackers could gain unauthorized access to client systems or communication services such as conference and collaboration, voicemail, SIP trunks and instant messaging,” Ozavci was quoted as saying.
No fear. There are things companies and security teams can do to keep up with the threats. One way is with VoIP penetration testing. Viproxy and Viproy are examples of two open source tools Ozavci developed for security testing of VoIP and Unified Communications (News - Alert) services and look for a number of different exploit possibilities to keep companies protected.
Even with these extra eyes needed – VoIP and UC technologies are here to stay. The advantages they bring to business communications far outweigh the risks. The thing companies should focus on now is having the proper protections and monitoring in place so success remains possible.
