How Your Wireless Network is Getting Hacked

These days, it is not uncommon to see a network of computers connected using wireless Hi-Fi technology. It is a simple process – you give your router a unique ID and secure the network with a password, so that, your network is safe and secure against any unauthorized person from accessing your machine.

Now you have set up a “secure” network and are relaxed and not worried about hackers, are you really safe? Well, not 100%. What? I have taken all the basic steps to protect myself, but how can the hackers get to my machine? Well, this is a valid question.

Please be aware of some hacking techniques could be used to gain access to your machine’s network. One of the techniques hackers use when hacking wireless networks is sniffing. What is sniffing?

Sniffing

Sniffing is the simple process of intercepting wireless data that is being broadcast on an unsecured network.

If you are at home, and your network is likely to be secured if you have already configured your network as such. However, places like hotels, libraries, Internet cafes and coffee shops are not secure.

Most of the time, sniffers target public places and hang out close to where Hi-Fi networks exist. There is even an activity known as Wardriving that involves driving around a city picking up wireless data, basically “drive by shooting”.

You can only be fully protected if you avoid unsecured wireless networks. If this is not the option, then the next best thing to do is to be careful about what information you send on an unsecured network.

The Final Words

Although there are a few other ways to crack Hi-Fi network, like spoofing and encryption cracking, sniffing is the most widely used technique to attack networks. New exploits are found constantly, making it difficult to ever ensure that you are 100% protected.

If you are especially a public figure, you will need to be extra careful. Most attacks happen not because the hackers are sophisticated geeks, but because someone was negligence to secure their network and/or logged in at some shady Internet cafe some where.

I strongly advise you to be extra vigilant and take proper steps to secure your network by using a long and highly randomized encryption key, never accessing a wireless network system while you are away from home or office. In short, never log in to a machine connected using Hi-Fi technology if the network is not yours.

Ethiopia The First in Africa with AMHS Extended Service from Radiocom, Inc.

Ethiopian Airlines and The Ethiopian Civil Aviation Authority have made us proud once again. I was happy to see this news release recently and wanted to share it with my readers. It feels good that Ethiopia is leading the aviation industry in Africa.

Recently, Ethiopian Airlines was ranked as the #1 profitable airliner in Africa, and #16 in the world. At this time of depressed economy, it is truly inspiring to read such good news from Ethiopia.

Press Release:

August 5, 2010 – Ethiopia, one of the first African Countries to transition from AFTN to AMHS, decided to do so with the assistance of ICAO and chose Radiocom, Inc as the supplier of excellence to design, supply, install and set to work an AMHS Extended Service. This turnkey installation was carried out by the Radiocom, Inc. experts, who put forward a solid well designed project to suit Ethiopia’s immediate needs, with the possibility of further expansion as required.

The contract was signed in 2009 and after the initial presentation to the Ethiopian Civil Aviation Authority (ECAA) carried out in Addis Ababa in June last year, the fine tuning began, the system was assembled in Radiocom, Inc. headquarters pre shipment, where the system was thoroughly tested. Once the equipment had arrived in Addis Ababa and customs formalities were under way, a team of 6 engineers and technicians flew to Addis Ababa to commence the installation. Additionally, the system for ECAA was complemented with two specific application data banks DBAIS and AeroBilling (see below).

For this contract, four (4) locations had to be equipped, ECAAs headquarters in Addis Ababa and a number of locations around the Bole airport, Mekele airport, Bahir Dar airport and Dire Dawa airport. Bandwidth needs had to be a big consideration (see below).

Additionally the Ethiopian Civil Aviation Authority requested the installation of an AMHS Training Facility. This is the first TRAINING CENTER of its kind in AFRICA; it is fully equipped to handle the training of in house personnel as well as hosting international training courses for neighboring countries. This is a service that is very needed in the region and could prove to be a very important, positive and popular asset for ECAA.

Both systems installed are AMHS Extended Service, with specific benefits when evaluating bandwidth requirements. The Radiocom, Inc. system is based on X.400 and X.500 protocol sets particularly X. 400 P3 communicating between the Message Transfer Agent (MTA), the Message Store (MS) and X.400 P7 communicating between the MS and User Agents (UA). This means low bandwidth requirement for communication between the MTA/MS in Bole and the remote location terminals in Mekele, Bahir Dar and Dire Dawa (all hundreds of miles away) need not be more than 9.6Kbit/s, and not the high bandwidth requirements that HTTP based systems require (for the same communication links with the remote location terminals, at least 64Kbits/s may be needed). This helps keep the cost of communication usage right down.

The complete system was left operational on April 30th, 2010 by the Radiocom, Inc. personnel. A further visit was carried out in June for final system acceptance.

Radiocom, Inc. supply a complete range of optional AMHS data banks, including a AIS data bank (DBAIS), a Meteorological data bank (DBMET) an Equipment Systems and Services data bank (DBESS) and an Airport Services Billing data bank (AeroBilling).

Radiocom, Inc. is looking forward to working with more African nations in their transition from AFTN to AMHS. This is a rapidly expanding region and Radiocom Inc. who has a good relationship with ICAO is ready to support their efforts to achieve a speedy and smooth transition throughout the continent.

Ethiopia: Utilizing Solar and Wind Power Energy

The old all you can eat buffet technology and careless consumption is now going on a diet. The financial disaster of the past couple of years have taught many people to live with in their means of income. Companies and individuals are trying to find out ways to cut their expenses and save money. As a result, many entrepreneurs are coming up with great green solutions. Out of the many green solutions, I am most interested in are the following:

  • Solar Power Energy
  • Wind Power Energy, and
  • Wave Power Energy

Solar and Wind Power Energies are abundantly available in Ethiopia and all over Africa. I believe that it is just a matter of time for the African countries to catch up with these technologies. Israel, Denmark and Germany are great example countries for innovative utilization of solar and wind energy.

Wave energy is too complicated and expensive for even developed countries like Canada to undertake.

No wonder that I was excited when I read that Ethiopia was working on a Wind Power Energy project.

State electricity company Ethiopian Electric Power Corporation (EEPCo) is considering an ambitious proposal for the construction of a 300 MW wind farm in eastern Ethiopia near the Djibouti border.

The Ayisha Wind Power Project is a planned joint venture of foreign and Ethiopian companies led by Dr Peer Ederer of Germany, director of the Human Capital Center at the Lisbon Council, a Brussels-based think tank, and scientific director of the European Food and Agribusiness Seminar. It has an estimated cost of $600 million, to be covered by a combination of funding from the African Development Bank and private capital.

The idea is to use local skills and resources as much as possible and to this end three local Ethiopian firms and engineering students at Mekelle, Bahir Dar, Adama and Addis Ababa universities are expected to participate in the technical and technological aspects of the project.

If it goes as planned, the wind farm could be developed within three years and Ederer says, “there are also plans to establish a wind turbine production industry in Ethiopia under the auspices of the German Technical Cooperation Agency (GTZ)”.

EEPCo is currently developing a 120 MW wind power project in the Ashegoda area in the northern Tigray state and has plans for other smaller projects in other parts of the country.

Until now, Ethiopia has relied on hydropower to meet its energy needs but following a rapid increase in demand in recent years this has proved to be inadequate.

Do you have any favoured green technology? Is there any green technology you can take with you to Africa? Share with us.

China’s Solution for Mass and Green Transportation: Build Straddling Buses

There are more than 1.4 billion people in China. The economy is growing, many have become millionaires and even billionaires just in the past 30 years. Along with growth, comes infrastructure and transportation challenges.

In trying to have a green technology that can transport many people in an already existing infrastructure, Chinese developers have come up with a paradoxical, environmentally-sound solution to speed up traffic. How you may ask? Their answer is to build straddling buses.

Shenzhen Huashi Future Parking Equipment company is developing a 3D Express Coach that will allow smaller cars to drive underneath it – just like a tunnel.

The new bus dubbed, the “Straddling Bus” is a light-rail train system and will stand about 4.5 metres high with two levels. Passengers will board the upper level while smaller vehicles less than 2 metres can drive right through.

Facts about the Straddling Bus:

  • Powered by electricity and solar energy
  • Can reach speeds of up to 60 km/h
  • Can carry 1200-1400 passengers at a time
  • Each bus will cost $500 million yuan (approximately $73 million USD)
  • Construction of the first 115 miles of track will begin in Beijing’s Mentougou district at the end of 2010

The future potential of this technology is very promising. I can see many countries ordering these buses from the Chinese firm. Canadian metro cities could definitely benefit from using these buses.

Ethiopia’s population is growing fast and such buses could be very well utilized in Addis Ababa. I hope that these great buses will be available in my life time in Addis.
