Mobile Satellite Broadband for Events

Events come in all shapes and sizes from little cosy gatherings to gigantic extravaganzas. They also take place in allsorts of locations from city centres to remote mountaintops. Often they will be arranged in ad hoc places which do not have any existing telephone or internet access infrastructure.

Unfortunately this can present a problem for today’s event organisers with the modern day requirement for connectivity everywhere. Go to any country festival nowadays and you will be dazzled with a wide array of items for sale from clothing to foodstuffs to souvenirs. Event organisers have so many ways these days to engage with audiences far beyond the immediate vicinity of the event and this can often be the key element that define their success.

So whether its up to the minute twitter feeds, broadcast access to seminars or demonstrations, live web radio streams, guest wireless internet access or credit card transaction processing, the many and varied ways which telecommunications access to the rest of the world can enhance an event offer opportunities galore for event organisers and attendees alike.


At Apogee Internet, we have it all covered wherever your event may be. On a boat in the middle of the Irish Sea or at the top of Ben Nevis we can provide your event with high speed Internet access at the core of our offering provisioned across the Astra fleet of spacecraft. This service can be provisioned to cover any location in Europe, the Middle East  or Africa. We can provide the service with Engineers to set up and manage the equipment or, if preferred, as an equipment only service for your own technicians to take care of. Our comprehensive and easy to follow instructions make the set up achievable by anybody with extremely rudimentary knowledge of networks and we can provide remote support too if required.

Once the connection is established, the additional services can be applied so whether its point of sale machines or simply providing wireless network access to be made available to the area, we have the equipment available for hire to facilitate any eventuality. We would be so bold as to say that if you can imagine it, we can very probably make it happen. If you have an event coming up and you would like to enhance the facilities and engage with an audience from afar, give us a call today.


If you are in the UK, you can call us free on 0800 012 1090. If you are elsewhere in Europe, the Middle East or Africa, call us on +44 1560 321349.

Which website shopping cart?

We have recently undertaken a study to determine which of the many shopping cart systems we should use on a customers website. After a long process trawling through the myriad of options we finally reached a shortlist of 8 candidates.

These candidates were:

  • Avactis
  • CS Cart
  • Cube Cart
  • Magento
  • OS Commerce
  • Prestashop
  • Virtuemart
  • Zen Cart

Now, with that part done the hard work begins.

The fact of the matter is that all of the choices in the list above are great ones. Any of these shopping carts will, with the right implementation, produce an excellent level of functionality on any website. The trick is to understand your own requirements first and identify which of the options most closely fits your own requirements, not only today but also your anticipation of what they will be in 6 months, 1 year and possibly even more.

So lets look at the pros and cons of each.

You can find the comparison HERE.


How Does Secure Socket Layer (SSL or TLS) Work?

The Secure Socket Layer, SSL for short, is a protocol by which many services that communicate over the Internet can do so in a secure fashion. Before we discuss how SSL works and what kinds of security it provides, let us first see what happens without SSL.

Life on the Internet without SSL

Let us compare communications between computers on the Internet and communications between people over the telephone. Without SSL, your computer-to-computer communications suffer from the same security problems from which your telephone communications suffer:

  • Who are you talking to? In a phone conversation, how can you be sure that the person who picks up the phone at the other end is really the person you are trying to call (especially if you have never spoken to them before)? What if your phone call was intercepted or re-routed, or what if someone else is answering your call recipient’s phone? There really is no way to be sure you have reached the right person, especially if they are actively trying to fool you.
  • Eavesdropping? As you are aware of from watching TV or reading, it is very easy to tap phone lines: the police and spies do this all the time to covertly gather information. It is not easy to detect if your lines are tapped. The same applies with communications over the Internet — how can you be sure that your communications are not being “tapped” and recorded?  This is especially problematic in public wifi hotspots.

This results in two very real security issues for communications over the Internet: 1. knowing for sure that you are connecting to the right servers  (i.e. those at your bank and not those at a hacker’s or phisher’s web site), and 2. knowing that your data is safe from prying eyes during transit to those computers. This is where SSL comes in.

Enter the Secure Socket Layer (SSL)

To solve these problems to a large degree, most Internet services support use of SSL as a mechanism for securing communications. To illustrate how SSL works, let us use another analogy.

Client wants to communicate with a company to send important information back and forth. Client wants to be 100% sure that s/he is communicating with this particular company and that no one can eavesdrop on or intercept the communications. How can s/he do this?

  • Client sends a courier to the company’s address.
  • The company has envelopes that, when closed, can only be opened by the company. The company and the courier go together to a trusted third party — a notary — which makes the company provide documentation to prove its identity. The notary certifies the company’s secure envelopes and the courier takes these back to the client.
  • The client gets the envelopes and, if it trusts the notary’s reputation, can be sure that they are actually from the company indicated.
  • The client also has secure envelopes that, once sealed, only the client can open. It puts some of these in one of the company’s secure envelopes and sends them back to the company.
  • The company gets the sealed secure envelope. It opens the envelope (as only it can). It now has the client’s secure envelopes.
  • The company has another kind of envelope that can be opened and sealed only by using a special combination. The company puts this special envelope with the combination lock, together with the combination, into one of the client’s secure envelopes. The company seals the envelope.
  • The company has another type of secure envelope that anyone can open, but which only the company can seal. If you open one of these sealed envelopes, you know for sure that it was sent by the company. The company puts the whole package inside this and sends it to the client.
  • When the client gets the secure envelope, it opens it and thus knows that it came from the company. It then opens the next secure envelope inside that can only be opened by the client. Inside it gets out the combination-envelope and the combination itself.
  • The client the puts his data in the combination envelope, seals it and sends it to the company.
  • The company receives it, opens it, and puts the response in the same secure envelope and sends it back.
  • The procedure is repeated as often as necessary for required communications.

SSL relies on the concept of “public key cryptography” to accomplish these tasks. In normal encryption, the two parties communicating share a “password” and that password is used to both encrypt and decrypt messages. While this is fast and efficient, how do you communicate these passwords to people you have not yet met in a way that is itself secure?

In “public key cryptography”, each person has two keys — a “public” key and a “private” key. Anything encrypted with the user’s public key can only be decrypted with the private key and vice versa. Each person then tells the world what his public key is and keeps his private key safe and secure, and private.

If John sends Mary a message encrypted with Mary’s public key, then only Mary can open it, as only she has her private key. This is like an envelope that anyone can seal but which only Mary can open.

If John sends Mary a message encrypted with John’s private key, then anyone can open it, as everyone has access to John’s public key. However, successfully opening the message proves that it was sent by John and no one else, as only John has access to his private key. This is like an envelope that only John can seal, but which anyone can open and thus prove that John sealed it.

SSL in Action

So, let’s see how SSL actually works for securing your communications over the Internet. Before the communications occur, the following takes place:

  • A company wishes to secure communications to their server
  • They create a public and private key for (this is also known as as “SSL Certificate“).
  • They go to a trusted third party company such as Thawte or Verisign: Thawte makes the company prove its identity and right to use the domain. This usually involves a lot of paperwork and paying a hefty fee.
  • Once the verification is complete, Thawte gives the company a new public key that has some additional information in it. This information is the certification from Thawte that this public key is for the company and and that this is verified by Thawte. This certification information is encrypted using Thawte’s private key… we will see why below.

Then, when Client wishes to communicate with the company at,

  • Client makes a connection to with its computer. This connection is made to a special “port” (address) on that is set up for SSL communications only.
  • When Client connects to on its SSL-secured port, the company sends back its public key (and some other information, like what Ciphers it supports).
  • Client gets the public key and decides if it is OK…
    • If the public key has expired, this could be a problem
    • If the public key claims to be for some domain that is not that could be a problem.
    • Client has the public key for Thawte (and many other third party companies) stored in its computer — because these come with the computer. Thus, client can decrypt the validation information, prove the validation is from Thawte and verify that the public key is certified by Thawte. If Client trusts Thawte, then Client can trust that he/she is really communicating with Company. If Client doesn’t trust Thawte, or whatever Third Party company is actually being used, then the identity of who is running the computers to which Client is connecting is suspect.
  • If the client doesn’t trust the server, then the communication is terminated.
  • If the client has its own SSL certificate installed, it may send that to the server at this point to see if the server trusts the client.  Client-side SSL certificates are not commonly used, but provide a good way for the client to authenticate itself with the server without using a username or password.  In the case where this is used, the server would have to know about the client’s certificate and verify it in a similar way to how the client verified the server.  If this fails, the connection is terminated.  If a client-side certificate is not needed, this step is skipped.
  • Once the client is happy with the server (and the server with the client, if needed), then the client choose an SSL Cipher to use from the list of encryption methods provided by the server, and generates a “symmetric key” (password) for use with that Cipher.  The client encrypts this password using the server’s public key and sends it back to the server.  The server (and only the server) can decrypt this message and get this password, which is now shared by both the client and server.
  • The client will then start communicating with the company by encrypting all data using this password and the chosen Cipher. Normal “symmetric” (password-based) encryption takes place from this point forward because it is much faster than using the public and private keys for everything. These keys were needed to enable the company (and possibly the client) to prove its identity and right to and to enable the client and server to generate and securely communicate a common password.

So, Are there Limitations to This Process?

This all sounds great — what are the down sides? There are a few.

Key Length: The statement that “only someone with the private key can decrypt something encrypted with the public key” is true so long as the private key cannot be “guessed”. Hackers may try to do this by trying all possible private key combinations. Older “40bit” keys can be broken by trial and error if one has access to vast computer resources and a good amount of time. These days, keys used in SSL are 128bit or better. There are so many possible keys with 128bit that it would take significantly longer than the age of the universe to “guess” one.

Trust: While use of SSL ensures that your communications cannot be spied on, it comes down to trust to ensure that you are actually communicating with your intended company. This is reflected in the validation of and your trust of the third party organization. Some “secure sites” do not bother to get a third party’s approval and have their keys approved by “themselves”. Others use third parties that are almost free and which spend very little effort in validating the company. In these cases, SSL provides you with no real assurance that you are really talking to your intended company and not some hacker trying to forge their identity to communicate with you in a manner in which you think you are safe.

For defensive use of the web, you should pay attention to warnings generated by SSL when you connect to secure sites. Such warnings include “expired certificates”, “domain name mismatches” — where the domain name presented by the company is different than the one to which you are connecting, and “non trusted certificates” — where the public key (certificate) presented by the company was not validated by a third party that your computer trusts. In all of these cases, you should be wary.

Ciphers: SSL uses one of a large variety of possible “ciphers” to perform the symmetric encryption.  Use of a poor/weak cipher can result in fast SSL that is easily compromised.  Currently, it is recommended that one use 128-bit or stronger AES encryption as your cipher.  See: 256-bit AES Encryption for SSL and TLS: Maximal Security.

What Services Can be Protected With SSL?

Almost any Internet service can be protected with SSL. Common ones include WebMail and other secure web sites such as banking sites and corporate sites, POP, IMAP, and SMTP. LuxSci provides SSL services to protect your username, password, and communications over all of these and other services.

The Importance of Video to Unified Communications

Enterprise Connect was held last week in Orlando. Among what seemed to be a great deal of interesting presentations and tutorials was a discussion on the role of video in unified communications.

John Bartlett, the principal of NetForecast, posted at No Jitter on a presentation entitled “UC in 2011: Myths, Realities and What Comes Next?” He started out by paraphrasing Phil Edholm, vice president of technology strategy and innovation for Avaya, who suggested that video is more important when the session is persuasive in nature, as in a sales call.

Bartlett wrote that John Del Pizzo, program director for IBM’s Unified Communications and Collaboration Software, disagreed. Del Pizzo said that the need for video extends to any communications in which it is important to get feedback. On a more pragmatic level, he said that video can focus a meeting by, for example, keeping participants from multitasking.

Edholm ended with his own viewpoint:

I think to understand these use cases we need to go back to the basic social instincts of humans and how we were designed to communicate. We do best in small communities where we know the people and we can judge how they will react to what we say. We get a lot of that information visually. I think what video conferencing does for us is allow us to more quickly form those small communities even though we are not co-located. Once we have been able to form the social connections to the group, the group can then be much more productive in its work because we know how to communicate.

Clearly, video is the next big thing in unified communications. It’s interesting to read about folks who spend much of their time on the technical issues related to adding video to established unified communications platforms change pace and discuss the topic from a more theoretical point of view.

Their points are well taken. There is essentially no communication that isn’t better with video. There may be specific cases where it isn’t ideal, such as the incremental benefits not being cost-justified or cases in which participants don’t want to be on camera — or doesn’t want his or her work area on camera. The bottom line on video remains clear: It is coming and coming quickly.
