Will You Add? - 7 Common Security Issues Found in Most VOIP Implementations
To watch satellite TV on PC or internet satellite TV is the future for TV viewers like us to watch our favorite shows. This is a bold statement but from the rising popularity of PC satellite TV in American homes, it could become a reality. So how do we set up our computer to watch satellite TV on PC? Ri
3) Encrypt data to all VOIP admin interfaces
Most VOIP directory servers default to HTTP,FTP, and Telnet for Administration capabilities. ENsure that only encrypted protocols are allowed to minimize
In our previous installment on medical billing, we covered the basics of enteral nutrition and billing and how it got to be such big business. In this installment we're going to review the GE0 record, fields 1 through 8, which is the CMN that has to be sent to the carrier with each enteral bill that is
As with most technologies, we must understand the risk that VOIP may bring into the existing network. Companies must understand the technology in depth before pushing it out in any network. This article will attempt to explain the 7 most common vulnerabilities found in VOIP networks.
1) Separate VOIP and Data Networks.
Ensure that VOIP and Data networks are configured to use separate VLANs. This will not only segment broadcast domains, it will allow for in-depth quality-of-service (QoS) configurations.
2) Implement ACLs between VOIP and Data Networks
VLANs are not enough. You need to ensure that ACLs are configured between Data and Voip networks to ensure access is allowed to needed services. This will also help protect against malware attacks.

Below is an article of rambling writing tips and interesting little tid bits. I could probably write an article a week directed at these. Some will help would be writers and some wont but one thing for sure is that most of them are interesting.1. FootnoteA footnote is a complete bibliogr

It’s hard enough worrying about gigabytes and terabytes. Not to mention the incredible intricacies involved with converting your existing database management architecture to a storage area network.Indeed, the last thing you need is to waste precious time searching for missing hardcopy documents t

One of the old saws of public speaking says that you should 'Tell em what you're gonna tell 'em. Tell 'em. Then tell 'em what you told 'em.' When you want to make a point during your presentation, you can use a similar formula. You tell 'em the point, illustrate the point, then tell 'em the point again.

The first step towards building a mutual understanding between you and your prospects in MLM prospecting is to ask questions. This will make your prospects feel that you are genuinely interested in knowing more about them and not just selling your product or service. It is a great way to win the
3) Encrypt data to all VOIP admin interfaces
Most VOIP directory servers default to HTTP,FTP, and Telnet for Administration capabilities. ENsure that only encrypted protocols are allowed to minimize attackers capturing clear-text passwords.
4) Secure VOIP Phones
VOIP phones should be further secured with passwords so that users can not easily corrupt the configuration. THis will also minimize potential attackers ability to glean information out of the phones.
5) Harden VOIP Directory Servers
VOIP Directory servers are often overlooked when other servers such as WWW, EMail, and File-Servers are hardened. Companies should ensure that VOIP servers are hardened/secured with the same level of protection as other business servers/
6) Secure VOIP/Infrastructure Switches
Switch security is very important and is often overlooked. Companies need to secure switches to minimize man-in-the-middle attacks that easily reveal clear-text passwords and other information.
7) Document VOIP Systems
Companies often deploy VOIP systems without proper documentation. This may cause issues is a server is damaged or fails. Often times Administrators may not understand how the system works- especially if configured by a 3rd party.
