Cloud Computing and The Hosted Desktop Explained

Friday, March 5th, 2010

There’s still some confusion in the business world as to what cloud computing and the Hosted Desktop actually are – so we thought we would run through the main benefits on our blog.

Lots of people think that because they can already access their work remotely, they can already do what a hosted desktop can do – but these two ways of working are completely different from a technological point of view and there are so many more advantages to working via a hosted desktop!

Applications like “Go to my PC” or “My Workspace” are remote control applications rather than cloud computing. Working “in the cloud” offers better cost savings to companies and is much more secure in terms of data protection. Data is stored in a data centre rather than on an individual’s desktop or laptop, so if a desktop or laptop was damaged or stolen, no private data would be lost because it would be safe “in the cloud” in the data centre. Using remote control applications still means data is stored on the computer itself.
People no longer need a VPN client to gain access to their work data. All they have to do is click on an icon on their desktop and they are instantly connected to their work station as if they were actually in the office, sitting at their desk. It makes flexible working hours so much easier for employers to offer. It also means there is no disruption to business when staff can’t make it into the office. They might need to stay at home to look after their sick child who can’t go to school that day – or it might be because of really bad weather, like the heavy snow we had last month which crippled many businesses.

The Forum of Private Business (FPB) warned at the time that the severe weather conditions could cost businesses £230 million per day if they didn’t take steps to allow staff to work from home. That figure was based on one employee per company being off for one day and not working.

Using a Hosted Desktop also makes sense financially. There are no set up costs, in terms of hardware. You pay a monthly fee per user, which includes 24/7 IT support, so businesses can budget for IT costs, rather than pay per hour for IT support, and because all you need is a basic computer or a “thin client”, you use less energy so save on energy bills – and you reduce your carbon footprint!

Radio Humberside listeners get anti-phishing advice

Thursday, October 8th, 2009

Well, Chris Gooding is rapidly becoming GoCloud’s media star as he makes yet another radio appearance this week. We’re losing count now!

Chris, our sales & marketing director, who is also very technically skilled in IT, appeared on BBC Radio Humberside’s business slot at 7.50 am this morning to give some help and advice to local listeners who are worried about the latest phishing scam that has been in the news this week.

With thousands of victims it is important that Internet users are instructed how to protect their confidential information from criminals ‘phishing’ for their passwords and personal details. Chris provided plenty of advice over the radio but if you missed it here are some more tips on avoiding phishing attacks.

Hear GoCloud on KCFM

Wednesday, October 7th, 2009

Hear GoCloud’s Chris Gooding on KCFM between 1pm and 7pm on their news bulletins. Chris, our Sales & Marketing Director, is offering advice on how to avoid being the victim of phishing emails and giving away personal, financial and confidential information to criminals via emails and the web.

We have already put some online advice on how to avoid becoming the victim of phishing scams on GoCloud’s blog.

How to avoid phishing scams

Tuesday, October 6th, 2009

Phishing by crooks is essentially a crime where they lure you to a seemingly innocent web site and convince you to enter confidential information, usually personal details and bank account umbers, usernames and passwords.

It is easy to become avictim unless you are alert to the possibility when checking your emails. In a June 2004 experiment, 80% of 500 West Point cadets who were sent a phishing e-mail were tricked into revealing personal information.

Here are some easy steps to avoid becoming a victim of phishing:

  1. Never enter confidential details when requested by email unless you both know AND trust the source of the email. Be aware that the source (or sender) of an email can be forged so that it looks as if it came from a legitimate company such as your bank. Because of past phishing scams banks will NEVER ask for your password by email. Period. UK banks rarely use emails now except for sending marketing information.
  2. Most companies personalise emails that they send to customers e.g. Dear Mr Smith or using a username e.g. dell8756. So an email that is generic about the name e.g. “Dear Customer” is potentially fraudulent.
  3. Most phishing emails originate in China, Taiwan, South Korea and Russia so beware any websites in those country domains, particularly if you have no reason to do business with or know anyone in those countries.
  4. Always verify a website when being sent there from a link in either an email or an other website. You can use www.whois.com or http://www.nominet.org.uk. Remember, if a legitimate bank website asks for a password it will go secure ie the URL will begin https:// rather than http://.  You will find this is not the case with phishing websites as it requires the issuing of a security certificate to be able to go secure and it is very difficult for fraudster to get one of these certificates.
  5. Beware of link manipulation. Criminals are clever at making links look like they are going to legitimate sites but in the lower left hand corner of most browsers you can preview and verify where the link is actually going to take you. See point 3 supra. URLs can be complex to read so don’t take a chance if you are unsure.
  6. Use anti-phishing software – the software searches for text that is often contained within phishing emails e.g. Symantec However, be aware that phishers can use images instead of text to fool anti-phishing software.
  7. Toolbars – many toolbars released for use in Internet Explorer or Firefox browsers will warn users when they visit a suspected phishing site e.g. Google as do the most popular browsers.
  8. If you suspect you have been the target of a phishing attack, change your password immediately. Also inform your bank, credit card company if you think your account may be compromised. It is a lot easier to prevent the removal of funds than to spend days maybe weeks trying to recover money taken from your account by fraud.
  9. Don’t use the same password for more than one account or website
  10. Don’t use passwords that are actual words, names, people, pets, sports teams. Not only are these easy for people who know you to guess but software programs used to hack accounts will use these obvious words when searching.
  11. Change your password regularly

GoCloud gives advice on radio on how to avoid phishing scams

Tuesday, October 6th, 2009

Local radio station KCFM have recorded an interview with Chris Gooding our Sales & Marketing Director.

This time Chris is offering advice on how to avoid being the victim of phishing emails.

We’ll have to get Chris an agent if he makes any more media appearances this week!

More than Hotmail users affected by phishing attack

Tuesday, October 6th, 2009

The scale of yesterday’s reported phishing attack on Hotmail users is much wider than previously thought.

Originally, 10,000 Hotmail accounts were reported to have had their login details published on pastebin.com. As the user names began with A or B it was reasonable to assume that over 100,000 Hotmail accounts on a full list may have been compromised; the 10,000 published may have been a taster for those criminal elements who purchase such information.

Today, the UK media are claiming to have seen a bigger, 20,000 name list, which in itself is not surprising considering the calculation we did yesterday that suggested the overall number of vulnerable Hotmail accounts was in six figures. However, the shocking news about the bigger list is that it includes service providers other than just Hotmail.

Yesterday, Microsoft said it was an industry-wide problem and they have been proved correct today with the new list including details of Gmail, Yahoo, AOL, Earthlink and Comcast accounts. This potentially puts millions of email accounts at risk and, of course, all the confidential and personal information that routinely passes through these accounts in legitimate emails may be read by dishonest third parties.

Microsoft said, “Our guidance to customers is to exercise extreme caution when opening unsolicited attachments and links from both known and unknown sources, and that they install and regularly update their anti-virus software.”

Once again we would advise users of any of the affected email providers to change their passwords now – and also to change their password on any other site that uses the same password. Phishers know that up to 40% of people use the same password on every website they visit.

We will be publishing some advice on how to avoid falling into the phishing trap later today

Hotmail targeted by phishing attack

Monday, October 5th, 2009

Microsoft confirmed today that thousands of its Hotmail email accounts have been compromised in a large scale phishing attack.

“Phishing” is the use of fake websites, that appear to be legitimate, to get users to type in their user names and passwords. Although bank account customers have been the primary targets of this type of attack the technique is widely used to get hold of all types of confidential information.

Uncomfortable as it is for Microsoft, the company says it is a phishing attack rather than the security of its servers being overcome in a hacking attack.

The success of the phishing attack became clear when over 10,000 names and passwords of Hotmail users appeared on the pastebin.com webiste.

“We are aware that some Windows Live Hotmail customers’ credentials were acquired illegally and exposed on a website,” said Microsoft.

“Upon learning of the issue, we immediately requested that the credentials be removed and launched an investigation to determine the impact to customers.”

Although lists of 10,000 names and passwords have been seen, the names began with A or B, which means that logically there could be another 100,000 compromised Hotmail accounts affected.

So we at GoCloud would advise any Hotmail user to change their password immediately.

Could hosted desktops have averted the risk to 43,000 Wigan school children?

Friday, September 4th, 2009

The mainstream media are quick to jump on any breaches of security involving cloud computing, and rightly so as security of personal and financial information should be of paramount importance to any organisation.

However, you are always left with the impression at the end of such stories that the more traditional way on storing the data, i.e. in-house servers and computers would have been more secure.

But the worrying tale from Wigan about the loss of a laptop containing the details of 43,000 local school children highlights circumstances in which a cloud computing and hosted desktop solution would have avoided this situation.

The Information Commissioner’s Office (ICO) has found that Wigan Council breached data protection law by allowing unencrypted data on school children to be downloaded to a laptop that was subsequently stolen from a locked cupboard.

Humiliatingly, Joyce Redfearn, the CEO of Wigan Council, has had to sign an undertaking stating that the council will encrypt data on portable devices in future.

IT professionals will also be worried that so much personal data about children could be downloaded on mass by a council employee.

In fact, the head of enforcement at the ICO, Sally-Anne Poole did comment, “I strongly advise organisations to avoid instances where employees can download large volumes of personal information.”

Sally-Anne Poole continued, “This incident could have been averted if the data was simply accessed from the main council computer network. Storing large volumes of personal information on portable devices is unnecessarily risky.”

However, presumably the employee was in a position where they felt they would have need to access all the information while using the laptop and so downloaded so much sensitive information. Of course, if the information had been securely accessible to users from any remote location there would have been no need to allow this massive or any other partial download of such a sensitive database to any computer, let alone a device as vulnerable as a laptop.

The fact that the laptop was stolen from a locked cupboard also highlights the fact that data stored on a business’ premises is a lot more vulnerable to theft (and fire) than data stored in the highly secure UK data centres where servers used in cloud computing are situated.

Obviously here at GoCloud we would see this as an ideal situation for the use of a remotely hosted desktop solution so that the personal information would not have had to be downloaded to a laptop and yet the remotely hosted desktop would still enable the employee to securely access the information from a home computer or a thin clientin an alternative work location.
