Without Desktop Virtualisation, you can’t attain True Business Continuity

Even if you’ve invested on virtualisation, off-site backup, redundancy, data replication, and other related technologies, I?m willing to bet your BC/DR program still lacks an important ingredient. I bet you’ve forgotten about your end users and their desktops.

Picture this. A major disaster strikes your city and brings your entire main site down. No problem. You’ve got all your data backed up on another site. You just need to connect to it and voila! you’ll be back up and running in no time.

Really?

Do you have PCs ready for your employees to use? Do those machines already have the necessary applications for working on your data? If you still have to install them, then that’s going to take a lot of precious time. When your users get a hold of those machines, will they be facing exactly the same interface that they’ve been used to?

If not, more time will be wasted as they try to familiarise themselves. By the time you’re able to declare ?business as usual?, you’ll have lost customer confidence (or even customers themselves), missed business opportunities, and dropped potential earnings.

That’s not going to happen with desktop virtualisation.

The beauty of?virtualisation

Virtualisation in general is a vital component in modern Business Continuity/Disaster Recovery strategies. For instance, by creating multiple copies of virtualised disks and implementing disk redundancy, your operations can continue even if a disk breaks down. Better yet, if you put copies on separate physical servers, then you can likewise continue even if a physical server breaks down.

You can take an even greater step by placing copies of those disks on an entirely separate geographical location so that if a disaster brings your entire main site down, you can still gain access to your data from the other site.

Because you’re essentially just dealing with files and not physical hardware, virtualisation makes the implementation of redundancy less costly, less tedious, greener, and more effective.

But virtualisation, when used for BC/DR, is mostly focused on the server side. As we’ve pointed out earlier in the article, server side BC/DR efforts are not enough. A significant share of business operations are also dependent on the client side.

Desktop virtualisation (DV) is very similar to server virtualisation. It comes with nearly the same kind of benefits too. That means, a virtualised desktop can be copied just like ordinary files. If you have a copy of a desktop, then you can easily use that if the active copy is destroyed.

In fact, if the PC on which the desktop is running becomes incapacitated, you can simply move to another machine, stream or install a copy of the virtualised desktop there, and get back into the action right away. If all your PCs are incapacitated after a disaster, rapid provisioning of your desktops will keep customers and stakeholders from waiting.

In addition to that, DV will enable your user interface to look like the one you had on your previous PC. This particular feature is actually very important to end users. You see, users normally have their own way of organising things on their desktops. The moment you put them in front of a desktop not their own, even if it has the same OS and the same set of applications, they?ll feel disoriented and won’t be able to perform optimally.

Do you really need a Cloud Broker?

A cloud broker is someone who can serve as your trusted adviser when it comes to your dealings with a cloud service provider. Sort of an IT consultant who: is familiar with cloud computing, can negotiate a mutually beneficial relationship between you and a provider, and help you manage usage, performance and delivery of cloud services.?But do you need one?

Is it even time for cloud adoption?

Of course, if you haven’t even started considering moving your IT systems to the cloud, what’s the point of reading this article, right? Well, if you’re running a business in Ireland or the UK maybe you should start thinking about it. The benefits (of moving to the cloud) are simply overwhelming. But then that’s for another post.

For now, let’s just briefly talk about the rate of cloud adoption so far. This should give you an idea what other decision makers nearby think about cloud computing and what they’ve done in this regard so far.

According to research conducted by the Cloud Industry Forum (CIF), the number of first-time users of cloud computing in the United Kingdom has risen by about 27% compared to last year.

The study, which was carried out by research company Vanson Bourne and which involved IT decision-makers from both the private and public sector in UK, also showed that 61% of companies are subscribing to cloud-based services. A similar research conducted last year (2011) revealed only 48%.

In Ireland, plans are underway to adopt cloud computing. According to Pricewaterhouse Coopers, 75% of Ireland’s CIOs and IT directors are already adopting a cloud computing strategy.

Definitely, the number of cloud adopters is growing. If that number already includes your hottest competitor, then perhaps there’s no time to waste.

But while a migration to the cloud should be in your pipeline, it shouldn’t be something you should rush into. Generally speaking, there are at least three kinds of services offered by cloud service providers: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).

Some providers offer variations of these services. You might only need one type of service or a little of everything. There are also technical and regulatory compliance issues that need consideration.

Obviously, if you have no idea where or how to start, you’ll need someone who can help you. But what kind of help do you need?

Let’s proceed by talking about the kinds of services cloud brokers offer as these are obviously indicative of the needs of current cloud customers.

What cloud brokers do?

Cloud brokers offer three main types of services.

Cloud?inter-mediation

Cloud inter-mediation services are designed to add value to existing services and improve capabilities. ?Examples of cloud inter-mediation include managing access to cloud-based services, carrying out performance reporting, and establishing stronger security.

Cloud aggregation

As mentioned earlier, some cloud customers may end up subscribing to multiple cloud services; most likely from different cloud service providers. To get optimal return on their various cloud subscriptions, these customers will need to apply data integration and make these disparate systems work together. They will also have to make sure data flowing from one system to another is kept secure. This is where cloud aggregation comes into play.

Cloud arbitrage

This entails finding the best cloud service provider(s) to solve a particular problem. One example is comparing different providers offering data storage services and identifying the one offering the most competitive rates.

Other cloud arbitrage brokers develop new solutions by combining the services of different cloud service providers and then offer them to cloud customers. While there are similarities between cloud arbitrage and cloud aggregation, the former is more flexible and allows the customer to transfer from one provider to another where conditions are more favourable.

Problems a cloud broker can help you solve

Just like with natural clouds, your experiences in cloud computing won’t be all white and fluffy. You’ll also encounter gray and uncertain (or even stormy) clouds.

One major issue in cloud computing is cloud security. In fact, cloud security (or the apparent lack of it) is the one thing that’s really clouding up the sky of cloud computing. But that doesn’t mean the cloud is totally insecure. Besides, there are certain types of information that really don’t require a high level of security. These types you can easily migrate to the cloud.

For sensitive information, you really need to conduct due diligence to make sure your cloud service providers’ data centres are secure enough.

Where exactly will your data be stored? Are there enough provisions for regulatory compliance? How will your data be segregated? Does the infrastructure readily support ?data forensics? Is there a sound disaster recovery/business continuity plan? These are just some of the questions that need clear answers before you sign a contract with a cloud service provider.

Also, before you sign, you need to study the SLA (Service Level Agreement) very carefully. Look at the guaranteed uptime. Is it enough to meet your own desired service levels?

Bear in mind that the answers to these questions may be too technical. This is one of those instances when a cloud broker can come in handy. As your trusted adviser, your cloud broker can break down the technical jargon and present everything in a language that you can make intelligent decisions from.

A cloud broker will also be able to study the cloud provider’s security architecture and policies and determine whether they’re sufficient to meet your own security requirements. Basically, a cloud broker will not only help you obtain answers to your questions.

He will also know exactly what vital information to extract from providers in order to ensure that you find the best deal possible.

How Internal Auditors can win The War against Spreadsheet Fraud

To prevent another round of million dollar scandals due to fraudulent manipulations on spreadsheets, regulatory bodies have launched major offensives against these well-loved User Developed Applications (UDAs). Naturally, internal auditors are front and center in carrying out these offensives.

While regulations like the Sarbanes-Oxley Act, Dodd-Frank Act, and Solvency II can only be effective if end users are able to carry out the activities and practices required of them, auditors need to ascertain that they have. Sad to say, when it comes to spreadsheets, that is easier said than done.

Because spreadsheets are loosely distributed by nature, internal auditors always find it hard to: locate them, identify ownership, and trace their relationships with other spreadsheets. Now, we’re still talking about naturally occurring spreadsheets. How much more with files that have been deliberately tampered?

Spreadsheets can be altered in a variety of ways, especially if the purpose is to conceal fraudulent activities. Fraudsters can, for instance:

  • hide columns or rows,
  • perform conditional formatting, which changes the appearance of cells depending on certain values
  • replace cell entries with false values either through direct input or by linking to other spreadsheet sources
  • apply small, incremental changes in multiple cells or even spreadsheets to avoid detection
  • design macros and user defined functions to carry out fraudulent manipulations automatically

Recognising the seemingly insurmountable task ahead, the Institute of Internal Auditors released a guide designed specifically for the task of auditing user-developed applications, which of course includes spreadsheets.

But is this really the weapon internal auditors should be wielding in their quest to bring down spreadsheet fraud? Our answer is no. In fact, we believe no such weapon has to be wielded at all?because the only way to get rid of spreadsheet fraud is to eliminate spreadsheets once and for all.

Imagine how easy it would be for internal auditors to conduct their audits if data were kept in a centralised server instead of being scattered throughout the organisation in end-user hard drives.

And that’s not all. Because a server-based solution can be configured to have its own built-in controls, all your data will be under lock and key; unlike spreadsheet-based systems wherein storing a spreadsheet file inside a password-protected workstation does not guarantee equal security for all the other spreadsheets scattered throughout your company.

Solutions to Password Overload

If only technologists had their way, passwords and PINs would have long been replaced with more innovative (and admittedly, better) security solutions. But such is not the case. Those alternative solutions, which include biometrics, smart cards, and password fobs, effective as they may be, are just way too expensive to implement.

So although passwords and PINs may not be here to stay, they certainly won’t be going away soon either.

Why keeping passwords in memory is no longer possible

A couple of decades ago, it would have been nearly impossible to crack an eight-character password using brute force. Today, however, advancements in computing power are rendering the typical passwords of the past easily decipherable, forcing us to come up with passwords that are not only much longer, but also much more complex and hence difficult to recall.

For instance, memorable words like your favourite character (e.g. ‘skywalker’) may have been acceptable then, but not anymore. Today?s security systems will encourage you to insert numbers or even other keyboard characters as a means to once again counter brute force. Hence, ‘sk5%ywa936lker@#’ may be more acceptable.

Remembering that one alone can be pretty daunting.

To further complicate matters, the number of applications that require passwords for access is much greater than before even for a single end user. Ordinary end users have to keep track of passwords for their email account, network login, workstation login, online services, and so on.

The burden is even greater for your IT admins, who have to remember a larger collection of passwords that protect business critical systems and applications. Clearly, the team in charge of your IT security will need a way to manage all these passwords.

Password management solutions

Existing password management solutions typically come in the form of software applications that store passwords. Basically, all you need to remember are your login details for the app a.k.a. the ?master password?. Once you’ve gained access inside, you can then retrieve any password you stored there.

Some of these apps are installed in portable devices like Pocket PCs, PDAs, or smartphones, which you would normally take along with you. For as long as the device stays with you, your passwords will be in safe hands. What’s more, you can retrieve them anywhere you go.

But obviously, there’s a problem. What if the device gets misplaced or stolen? Although the person who ends up with your device may not be able to gain access into the app and your passwords, neither will you. A better solution would therefore be an app that can be accessed anywhere but is not susceptible to getting lost.

Web-based password manager

A web-based password manager fits the bill. You don’t have to take it with you, but still you can access it almost anywhere. A typical web-based password manager will have all your passwords stored in a centralised, highly secure location.

If you want, you can even use your mobile password manager along with the web-based one. Ideally, your web-based password manager would have a copy of all the end-user passwords as well as the master passwords of your organisation.

With an easy to access but highly-secure web-based password manager, you no longer have to come up with passwords that (ironically) are supposed to be easy to remember but hard to crack at the the same time.

Furthermore, password managers are ideal for keeping passwords that have to be changed every-now-and-then; a requirement that’s becoming all too common in organisations bent on enforcing more stringent controls.
