Although not a new subject here at DecryptedTech we thought it was time for us to dive into three of serious issues in the security world (out of many). The three we are covering today are emerging technologies, stale technologies and how the security, and IT, skill set seems to be diminishing. All three are cause for concern and often seen as at least contributing factors in breaches. What make this more interesting is that in many cases the three are connected.

For the majority of people the term wireless means a simple router or access point (AP) and that is that. However, when you look at wireless on a larger scale you have to have a means to control access points in your organization with a little more efficiency. The thought of going from AP to AP and manually making changes to ensure proper coverage or channel plans is one that would keep most network engineers up at night. However systems that offer a centralized management point for multiple Aps are typically out of the range of small and even medium sized businesses. NETGEAR has stepped in and created a few products to cover this market. We have their WC7600 Wireless controller and a pair of WN370 Access Points in the lab, so let’s check this bundle out and see how it fits in.

Home networking gear has been making some leaps in speed and sophistication since its introduction. These leaps have made wireless in the home more usable and configurable. Much of the work on this side of the product (making things easier to configure and use) has been behind the scenes, but this work has pushed wireless technology further into our homes. Now the big ticket item is the new 802.11ac wireless standard. However there is still a huge market for 802.11n wireless products with dual concurrent bands (2.4GHz and 5GHz). Right now these wireless products are what you are going to see in the market and what consumers are interested in simply because of their prevalence. So with that in mind we are taking about an 802.11n wireless router from Asus, the RT-N66U Dark Knight Wireless router.

Shuttle has presented two interesting home NAS devices from Omninas line, models KD21 and KD22. Solutions have elegant aluminum housing with space for up to two 2.5 or 3.5 inch disks and SATA interface.

Since its introduction there has been something of an internal battle with wireless. On the one hand it is very convenient; you just connect to an access point and you have freedom as long as you are inside the network rand. On the other the speed is not always that great and, if the signal is too weak, you can end up dropping packets, files and losing data. Over the years there have been great improvements in wireless speed, but no matter what it has never been able to match the speed of a wired connection. At least it could not until 802.11ac wireless arrived on the scene. This new specification offers a theoretical limit of 1.3Gbps over a 5GHz wireless connection. We have already taken a look at a router and USB 2.0 adapter, now we are going to look at what happens when you put USB 3.0 into the mix with the TRENDNet TEW-805UB adapter.

In the world of the enterprise bandwidth is everything. If you do not have enough or you cannot keep your systems running then you are sure to lose money. The problem is getting the bandwidth you need without spending too much to get it. The current backbone to client standard is 1Gbe (Gigabit Ethernet). This give you plenty of bandwidth for client operations as well as voice traffic (which is typically about 20% of your data usage. Now this is great when you are talking about client to server traffic, but what happens when you need servers to talk to each other or servers to talk to storage? Here you need significantly more bandwidth than you do out to clients. Right now at the high-end of the spectrum you have 40Gbe (with 100Gbe coming very soon) and just under this is 10Gbe. Traditionally 10Gbe has been the playing ground for fiber optics or for TwianAixal cables. The problem is that these are not all that economical and end up out of the hands of all but larger enterprise networks. Things have changed though, just like 1Gbe over 10 years ago, 10Gbe is now hitting the price range that puts it into the hands of small and medium sized businesses. We are going to take a look at one of these options today in the form of the NETGEAR ProSafe XS708E 8-port 10Gbe Ethernet Switch.

Storage is something that everyone needs. No matter if you are a single end user or a gigantic corporation you have to have a place to keep your data. This one little fact has never changed and probably never will. The difference is that home users are now higher on the scale when it comes to storage needs than many small and medium sized business. Home users are maintain more and more data in the form of movies, music pictures and even installation files while many small businesses are only storing simple documents and perhaps a few databases.  It has changed the dynamic in the way storage products are marketed in many ways and this is not truly a completely good thing. While a normal consumer might store more information than a small business they do not have the same need to never be offline or unavailable. The typical home user also does not have the same number of connections to their data as a medium or even small business. There needs to be a class of NAS that can handle these requirements without pushing the price tag over the top. Synology has a very solid answer for these questions and more all bundled up inside the new DS1513+; this is a five-bay NAS that includes four 1Gbps LAN and a ton of other features. Let’s dive in and take a look shall we?

When wireless networking was first introduced it was a very cool concept and people bought into it. The problem was that it was also about as slow as dial-up internet was. The good news is that all technologies advance and wireless was non exception. Once the idea caught on we quickly ramped up in speed, but wireless was never quite able to keep up with a wired connection. We saw these connections leap ahead by a factor of 10 while wireless had small incremental speed jumps. All of that changed in 2011 when researchers built up the next specification for wireless speed, 802.11ac. This speed increase more than doubled what wireless was able to do previously. Suddenly wireless was just as fast as a wired connection (in theory). We have a few routers and adapters in the lab and will be taking a look at them. Today we are going to show you the TRENDNet TEW-812DRU AC1750 dual band wireless router.

The Era of the Ethernet began on 22nd May in 1973. when Robert Metcalfe, a researcher at the famous Xerox PARC research center in Palo Alto, California, sent a brief letter in which he proposed a medium for transmitting electromagnetic waves, and among other things drew the bottom sketch of the new emerging standards.

Belkin has officially announced they will take over Cisco's home networking solutions department. With this move Belkin also gets the Linksys department with which the company intends to hold a 30 percent market share of networking solutions for home users and small businesses in the U.S.
