NASDrives.net Home Network Attached Storage Buyers Guide
Network attached storage (NAS) for the home is all the rage. NAS provides a way to share files, access music and movies and backup your data. To help people interested in a NAS device choose the best network attached storage for them, NASDrives.net presents this buyers guide.
What is Network Attached Storage?
Network attached storage devices are small servers dedicated to nothing but file sharing. Instead of having to physically connect a drive to your computer, you can just plug a device into your home network that provides additional storage space. Storage prices are falling and adding 250gb, 500gb or even 1 tb (terabyte) is becoming cheap and easy.
Advantages of NAS
* It’s a simple way to add data storage to all your computers rather than just one.
* Multiple computers are able to access files anytime and do not rely on a host PC for file sharing.
* Savings on your electric bill because a power hungry computer or server need not be on 24 hours a day to share files.
* New media server features allow for centralization of your music and movie library so it can be shared by everyone on your network and even streamed to home audio and video devices.
* Provides a central place for backup storage.
Explanation of features
USB Print Server – A USB printer can be connected to the NAS device and it can share the printer over the network.
Media Server – The device can stream media to any device on the network capable of receiving it. MP3’s or movies can stream to your PC or movies can stream to a media center connected to your TV.
UPnP – Universal Plug and Play. UPnP is a dynamic zero-configuration protocol used for device interconnection. That’s quite a mouthful but what it means is that UPnP devices can talk to other UPnP devices without any intervention from you. It just works.
DLNA – Digital Living Network Alliance. DLNA is a certification built on other technologies. DLNA certification insures that certified devices will be able to talk to each other and provide a minimum level of features.
RAID – Redundant Array of Inexpensive Disks. RAID, in it’s many configurations, sacrifices some disk space for a level of data redundancy. RAID 1, called mirroring, makes an exact duplicate of the primary disk. If the primary disk fails then the secondary “mirrored” disk can take it’s place until you buy a replacement. RAID only helps in cases of hardware failure and is not to be mistaken for a backup strategy. If you accidentally delete a file on the primary disk the file is deleted on the mirror as well.
FTP Server – File Transfer Protocol server. Most people will not need this and will use Windows file shares instead. Some security cameras and office scanners have the ability to save to FTP servers and in those cases, and many more, this feature would come in handy.
iTunes compatible – The NAS has the ability to publish it’s media files to a computer running iTunes. The computer with iTunes would then be able to play those media files.
USB Ports – External USB storage can be added on to extend the capacity of your NAS. This can insure your NAS is never obsolete! When you run out of space you can buy an inexpensive external USB disk and plug it into your NAS. A few systems will use these for USB printer sharing or as a host for your digital camera.
Gigabit Ethernet – 1 billion bits per second transfer rate. Most wiring done in homes or offices in the last 5 years was gigabit rated but the equipment is still a bit more expensive than 100 megabit so most homes and small offices do not support this. Gigabit will get cheaper home and SOHO use so it’s still a good feature to have.
Backup Software Included – A major reason to add NAS to your network is backups. Quite a few drives come with Windows backup software to automate this important but often overlooked task.
Vista Support – Vista removed support for some older Windows file sharing technologies and some NAS drives still rely on it. If you use Vista in your home or office, make sure the NAS says it’s Vista compatible.
Mac support – Native Mac support is spotty so make sure the device is compatible with your Mac and your version of the Mac OS. Macs are able to access Windows shares so this really isn’t much of an issue.
Active Directory support – If you’re running a Windows Server or Windows Small Business Server in your office then you need this. It allows your existing network users to use the file shares on the NAS without creating new usernames and passwords. Very handy.
Gigabit Jumbo Frames – Geekspeak for faster networking.
File access via web server – This allows you to browse files on the NAS via a web browser. This would be handy if you were trying to access it from a system that did not support Windows files sharing or if you just preferred to access the files that way.
DFS support – Distributed File System. This is another Windows technical term that means that a remote shared folder can be mirrored to the NAS device. This is great for a business with a Windows Server and multiple locations.
Accessible via the Internet – A few companies have setup central servers that act as a middleman between Internet connected users and your NAS. This makes your files accessible by anyone, anywhere. Of course, everything is password protected for security. The possibilities here are endless.

Don’t Let Zombie Computers, Home Computer Hacking, and Drive-by Hacking Compromise your Finances
September 28th, 2009Spyware, Keyloggers, Hackers, Cyber Terrorists, Cybercriminals, Cybergangs, etc. These threats are real and the fact is your computer is most likely infected already! Cybercrime is on the rise. You may not be the only one using your computer. Hackers may be using your computers and you may not even know it. Would you ever know it if your computer were taken over and being used by a hacker? Not likely. When a hacker hijacks a computer, the victim rarely knows. A computer that has been hijacked is one that is completely taken over by a hacker, or a group of hackers, to be used for their own purposes. The idea is that the real owner of the computer never knows their system has been hijacked, so the hackers can secretly use it whenever and however they want.
One of the latest hacking trends is called “Drive-by Hacking”. Popular wireless Internet access points have now become a major target for hackers. Hackers simply take their laptop computers in their cars and drive through business parks or residential neighborhoods remotely scanning for open wireless networks. This is the latest version of the drive-by garage door remote theft where criminal would use universal remote controls to open garage doors without arousing the suspicions of neighbors, police, or home security companies.
Today millions of businesses and homes have implemented wireless networks for their convenience, and, sadly, for the convenience of the cybercriminals. And they don’t even have to open your garage door to enter your home or business.
Now hackers can simply pull up outside, up to 600 feet away, and gain access to the network, the Internet, and every computer on the network. This kind of hacking has become so popular that you can even find public websites around the globe that sell maps to all the known “open” wireless networks.
Once your computer has been hijacked, the hacker claims ownership of your computer and there is little you can do unless you protect your computer in advance against this threat. In fact, in many cases when hackers have taken over a computer, they will even “heal” the computer by closing the security holes, so no other hacker can break into the computer and use it too. (Can you imagine? Criminals protect their hijacked computers from other criminals.)
Computers that have been hijacked and are under the control of a hacker are known as “zombies”. Some of the more popular uses for a zombie computer include using it to send spam emails, distribute pornography, download illegal copies of software, and to anonymously attack another computer, a business, a website, or even a government agency.
There have been many cases in the U.S. and around the world where a business or home computer has been hijacked and used for illegal purposes without the computer owner’s knowledge. These victims have had their computers used to distribute child pornography, deface websites, and even hack into government computers. In many cases, the owner of the hijacked computer (the business owner or the homeowner) has been arrested and hauled off to jail, only to be humiliated, demoralized and even convicted for crimes they didn’t commit.
See the ABC News’ 20/02 video about an unsuspected 16 year-old high schooler who was arrested as a child pornographer after his pc was hijacked and used to distribute child pornography. Click this link: ABC News’ 20/20 video.
Hackers are very good at hiding behind their slave or zombie computers. A hijacked computer is a hacker’s protection of anonymity. As unbelievable as it may seem, hijacked computers, zombie computers actually have a street market value in the hacker community. The better the computer and the faster the Internet connection of the slave machine, and the bigger the hard drive, the more it is worth on the market. Zombie computers are often leased out by hackers to other hackers, or even to organized crime groups, to be used for illegal purposes – without the computer owner’s knowledge. If a hacker or a cybergang can take over a hundred or a thousand computers, they have an army of computers at their disposal.
Here are some facts:
If your computer has become a “zombie” or a “slave” to a hacker, the use of your computer could be for sale somewhere on the Internet or an auction website. Your computer’s power is valuable to hackers.
Today, there are organizations that claim “ownership” of more than 450,000 zombie computers around the world that they use to anonymously send spam.
The best defenses are a combination of education and managed protection service. Off-the-shelve individual or combined anti-spyware, antivirus, and anti-spam software programs may not be sufficient protection, because hackers seem to stay one step of these programs. The popular off-the-shelf products offer you no personalized support. If you want help, you’ll pay for it over and over again! If you need a virus removed with these cheap programs, you’ll pay for it. You may get technical support from your PC manufacturer for security problems, but in most cases, you probably will not. Even if you do, it will likely be for a fee, and one that repeats itself should you need additional help down the road.
Because hackers will likely always be one step ahead of the security industry itself, software-based protection alone is not enough. 85% of current anti-virus users have been infected with a virus or worm! Have you ever had a virus you couldn’t get rid of? Has your computer acted funny or has it slowed way down due to a massive spyware infestation? Does your computer have a virus, spyware, malware, or hacker hiding inside? Test it now to be sure. Go to www.SayNotoHackersandSpyware.com to take a free Internet security audit to determine which trojans and hacker spyware tools might be infecting your computers.
To protect yourself, you need an Internet security team of experts making sure that you, your family, and your business computer are always safe and secure. The best protection you can have in today’s rapidly changing world of cyber-attacks is to have expert support for all your Internet security needs that will provide technical support without any hassles and without charging you extra fees. It will become even more critical than it is today as time goes on. You need to find your own personal team of experts to rely on. If you ever have a security problem, you will want to have a trusted expert you can call for professional help, without any hassles and extra costs!
Remember: When you say “No!” to hackers and spyware, everyone wins! When you don’t, we all lose!

How to Setup a Network Printer
September 26th, 2009If you are looking to start to assemble a personal home network, coming up with a plan can save money and time especially if you ever think you might expand your network in the future.
The whole point of making a plan is to come up with what you need for your network, after all there are many more things available than only having computers connect to the internet.
This includes WiFi, cables, or even both
Even though you probably only use a wired connection, will you be able to use WiFi in the future?
Just about everyone will at some point, and the difference in price between a cabled and Wireless router is tiny, and most wireless routers still have a 5 port wired hub built into them and this means you can use both wired and wireless appliances.
The whole point most people need a home network setup is to share an internet connection, in this case it’s imperative that the security of each computer and the router is loaded with the latest firmware, this includes Wireless Security, Router Security & each computer must have a firewall, anti-spyware and a firewall.
Sharing your hard drive on your network is easy or need a special computer, network hard drives are so easy to operate and they most of the time have sizes from 500gb to 2tb. There is even a wireless option available.
The speed of a network can play a major factor if you send big files, truth be told a wired network will always be faster than wireless, as a rule of thumb use cabled where possible and wifi where you have to, i.e laptops.
One huge mistake made when many of us are setting up a home network in the house is planning for future expansion, saving money today just means you will have to spend more later on, work within your budget but be realistic, setup the network that suits your needs and and budget.
