How to catch hackers on your wireless

Techdar talks about How to catch hackers on your wireless network and how to defend your Wi-Fi from future attacks

There are lots of tools around to help people carry out ARP-related exploits and if a malicious, Wi-Fi enabled neighbour decided to find out more about your network, this could be an effective way to do it. The good news is that there are some defences out there. The bad? They can be costly and don’t always deliver the protection you might expect.

WIMAX/3G Geek out

I must admit, I’m geeking out over WIMAX. WiMAX stands for the Worldwide Interoperability for Microwave Access. It will allow 70Mb/second upload and download which will allow for some pretty decent prawn video. So you’ll be able to go to youpawn and watch all kinds of prawn. There is an even better technology called 3GPP LTE (Long Term Evolution) on the way with is another improvement on the 3G stuff that is already out and marketed.

What is frustrating is that WiMAX will likely have the same level of control that 3G has. It will be tamed and completely corporate run. I plan on getting the new iPhone on 11 July 2008. After seeing the iPhone upclose I started to feel funny in my underpants. Iphone + 3G should shock my WiMAX arousal into erectile dysfunction.

It’s all about the killer app. If the big dogs pushing WiMAX (Nortel/Alvarion & Sprint/peon) can come up with a device that allows you to bypass XXX ass Comcast, AT&T and other broadband monopolies they will seriously shake up the market. WiMAX, 3G and others should be in the business of creating devices, drivers and software that allow you to network all of your systems from anywhere in the contiguous United States. That would be very cool. But they seems to have serious limitations (at least in the US).

Jun 11, 2008 (Hugin via COMTEX) —-Joint End-to-End WiMAX Solution Will Offer Operators Broader Coverage and More Capacity

TORONTO, ONTARIO and TEL AVIV, ISRAEL–(Marketwire – June 11, 2008) – Nortel(1) (TSX: NT: 9.13, +1.02, +12.57%)(NYSE: NT: 9.13, +1.02, +12.57%) and Alvarion(2)(R: 66.46, -1.77, -2.59%) Ltd. (NASDAQ: ALVR: 7.97, +0.46, +6.12%) entered into a joint strategic WiMAX agreement to create an end-to-end WiMAX solution to meet the needs of the evolving wireless broadband market. The Nortel and Alvarion mobile WiMAX solution is expected to combine industry-leading technologies from both companies to allow operators around the globe – including well-established service providers and new entrants to the wireless market – to simply and efficiently deliver high-speed wireless broadband for a variety of applications, mobile or nomadic, including VoIP, streaming music, and HD video.

The joint solution features the integration of Alvarion’s advanced radio access network technology, which has been proven in over 200 commercial WiMAX deployments, with Nortel’s core network solutions, backhaul solutions, applications such as Nortel’s number one carrier VoIP solution, and Nortel Global Services for WiMAX.. The Nortel and Alvarion WiMAX solution will allow operators to offer high speed wireless Internet access across large areas, including those currently underserved by broadband capabilities. The joint WiMAX solution will also provide the speed and capacity to help operators meet the exploding demand for true mobile broadband.

The ABCs of securing your wireless network


Ars Technica’s original Wireless Security Blackpaper was first published back in 2002, and in the intervening years, it has been a great reference for getting the technical lowdown on different wireless security protocols. As a sequel to the original blackpaper, we wanted to do something a little more basic and practical, because the number of devices with 802.11x support has greatly expanded since 2002. Wireless security is no longer the domain of geeks and system administrators, but is now an issue in the lives of everyday users, from the worker with a home office who wants to keep sensitive files secure to the homemaker who wants to avoid an RIAA lawsuit because the teen next door is a wireless-leeching P2P addict.

Which Is Faster Wireless Router Or Wired Internet

Wireless Routers vs Wired Router
fig. 1, which is faster wireless router or wired internet

Overview: Routers, switches and hubs (1) (a.ka Internetworking devices) give you access to the Internet (2) via some sort of ISP device (broadband modem, DSL ect) (3). The speed onto the actual Internet depends on the service you have purchased with your local ISP (4). They are the gatekeepers (AT&T, Comcast, Verison, Local ISP ect). This usually creates a bit of a bottleneck because your local area network (LAN) is much faster than your connection to the actual Internet. You actual connection to the Internet is controlled by your ISP. Wired LANs will allow you to get from 100-1000Mb/second, Wireless will get from from 10-250Mb (depending on how far from the wireless router you are and what type you get).

ISPs allow you to go anywhere from 56Kbs – 12Mbs:

Dial-up: 56Kbs – (4 minutes to download 1.7MB file)

DSL: up to 6Mbs – (2 seconds to download 1.7MB file)

Cable: up to 12Mbs – (1 second to download 1.7MB file)

*the math: 1.7 Mega Bytes is 13,600,000 bits (per second) of data divided by n, where n is your speed (i.e. 56K = 56,000 bits per second)
**There is a technology called WiMax Worldwide Interoperability for Microwave Access (802.16e) coming out that will allow wireless to go directly in your home from the ISP at 70Mb/second and that will beat every currently on the market.

If you have a home LAN (more than one computer in your home linked together connected to the Internet), your network is passing data at about 100Mb/second – which is really fast for even really large files. But this is where the Wireless vs. Wired Internet comes in. Don’t confuse your internal network speed with your connection to the Internet (see overview).

Should you go with a wireless or a wired router?
Any wireless router you get will have both options available, so you are better off getting a wireless. The cost isn’t usually that different unless you want a high end wireless which will usually be between $20-$50 more.

Which Switch is Faster, wireless or wired?
It really depends on what kind you get. However, the fastest wired router will beat the pants off of the fastest wireless. Wired routers go up to 100-1000Mb. Of course, I high end wireless can have everything a high end router has (including those super 1000Mb speeds).
