Telecoms offering network virtualization

With virtualization yet to make its way into the lexicon of common tech phrases, many business owners are still trying to decipher the full extent of its value. Various aspects of the service have evolved over time, and we can probably expect more to come. For now, however, one of its existing functions is getting a boost from the likes of AT&T and Verizon. Virtualized network services are complex and often difficult to understand, but their value is unquestionable. Let’s delve a little deeper.

The overarching theme of virtualization is combining hardware and software resources into one large, communal pool where individual servers and workstations can pull as much as they need, rather than allocating them inefficient individual puddles that either go dry, or unused. In a workstation model, this is realized in the form of minimally equipped endpoints that access much more powerful software and hardware resource pools via web browser.

When it comes to network virtualization, it’s quite similar to virtual private networks, or VPNs. Developments in cloud and software functionalities allow administrators to eliminate time-consuming and micromanaged VPNs while achieving the same swift and secure connections between servers, workstations, and other network-enabled devices residing in physically separate networks. VPNs are like pumps between each of your network ‘puddles,’ individual pieces that require individual maintenance. Network virtualization is like installing one pump with on/off switches on each outbound pipe.

This means that setting up a VPN for the addition of a satellite office is as simple as inputting a few simple pieces of information to gain a world of seemingly local network possibilities. In another example, rather than recabling your office when one department becomes too cumbersome to fit on one switch or hub, connections and protocols can be expanded and redefined by a software client.

With the increasing popularity of any service with the word ‘virtualized’ in it, telecom carriers Verizon and AT&T have begun offering this service to clients. Whether it's because your business has a growing list of locations, or because your local network needs the flexibility to grow swiftly without waiting for costly hardware and software expansions, these services have you covered.

Both Verizon and AT&T will offer three ways to manage your virtualized network: locally, from the cloud, or a hybrid combination of the two. Once you’ve decided on a framework and deployment strategy, make sure to take time with the transition. Established networks are complex and messy ordeals, and it’s better to start migrating those puddles over time rather than all at once. Instead, move them one-by-one so any problems that arise can also be dealt with one-by-one.

Although consumer-level companies like AT&T and Verizon are offering this service, not just anyone can hop on and start getting the most out of a virtualized network. It takes expert configuration, deployment, and most importantly maintenance. With 24/7 coverage of your network, we eat, sleep, and breathe cutting-edge technology. Call us today and we’ll bring your SMB into the age of virtualization.

VoIP: 5 security tips for SMBs

As SMBs continue their steady transition away from traditional telephony services in favor of VoIP, threats of cybercrime and fraud are more common than ever before. Risks to VoIP systems are distinctly unique from those posed to your other networks and understanding how to combat them is critical. Here are 5 tips for securing your organization’s internet-based communication devices and services.

Types of threats

The majority of VoIP services involve live communications, which often seem far more innocuous than stored data. Unfortunately, your business has just as much valuable information moving across VoIP networks as it does hosted on company servers. Internet-based calls are far more vulnerable to fraud compared to more traditional telephony services and face threats from identity theft, eavesdropping, intentional disruption of service and even financial loss.

24/7 monitoring

A recent study by Nettitude reported that 88 percent of VoIP security breaches take place outside of normal operating hours. This could be attackers trying to make phone calls using your account or gain access to call records that contain confidential information. This can be avoided by contracting outsourced IT vendors to monitor network traffic for any abnormalities or spikes in suspicious activity.

VoIP firewalls

Every VoIP vendor should provide a firewall specially designed for IP-based telephony. These protocols will curb the types of traffic that are allowed, ensure the connection is properly terminated at the end of a session and identify suspicious calling patterns. Consult with your VoIP or IT services provider about which of these features are available and currently in use at your organization.

Encryption tools

One of the reasons that eavesdropping is so common is because a lack of encryption. Inexperienced attackers can easily download and deploy tools to intercept and listen to your calls. Although some services claim built-in encryption, be sure to investigate how effective they really are. Many of these protocols require the same VoIP client on the receiving end of the call -- something that’s much harder to control. Encryption should be compatible with as many other software clients as possible to effectively prevent anyone from undermining the privacy of your calls.

Virtual private network

Virtual private networks (VPNs) create a secure connection between two points as if they were both occupying the same, closed network. It’s like building a tunnel between you and the call receiver. In addition to adding another layer of encryption, establishing a VPN can also overcome complications involving Session Initiation Protocol trunking, a recommended VoIP feature.

Password protection

Usually password protection refers to requiring password authentication to access sensitive information. However, in this case it actually means protecting the passwords themselves. Eavesdropping is one of the easiest, and most common, cyber attacks against VoIP networks and even with all of the protocols above, employees should be instructed to never give out any compromising information during a VoIP call.

VoIP is as important as any of your other network security considerations. It requires a unique combination of protection measures, and we’d love to give you advice on implementing any of these protections or managing your VoIP services. Give us a call today to get started.
