In The Wake Of Recent Talk Talk Hacks, How Secure Is Your Business?

Image Credit
In case you missed one of the biggest news stories of the year last week, here’s what happened. Major mobile telecommunications giant, Talk Talk, were hacked. Their database of customer information was compromised, leaking tons of data. Experts are calling it one of the biggest cyber attacks on a commercial company. The suspect? A fifteen year old computer genius acting alone. If a fifteen year old can hack one of the biggest companies in the world, it begs the question: how secure is your business?

Cyber theft and data breach is a very real concern for modern business. No-one is entirely secure from the threat, and it’s up to you to take action. Here are some tricks and techniques, straight from the experts, to help you stay safe.

Strong Passwords

Passwords might seem like a simple trick in the grand scheme of things. But, in reality, hackers find it very difficult to crack a strong password. The only way they’ll get through passcodes is when they discover patterns. When using the same passwords over and over again, it becomes easy to predict and break. Make sure you’re varying the passcodes on a weekly basis in the office. As for the password itself, try to use a different combination for every account you use.

Encryption and Firewalls

Encryption is a centuries old practice used to scramble and obscure data. It’s the best way to secure information. In simple terms, it turns your standard data and information into unreadable code. It is now impossible to read the true contents without the corresponding encryption key. A firewall is also a great way to keep malicious bots and hackers out of your system. A firewall creates a strong fence around your data, and repels suspicious intruders.

Data Storage

The manner in which you store the data is also crucial. When dealing with sensitive or incriminating data like customer information, you must be extra careful. A simple hard drive or shared server is not secure enough. Instead, you’ll need to look for a professional data center build service. They’ll create a bespoke server storage that is unique and personal to you and your company. It’s safe, secure, and essential!

Physical Security

Despite all these digital security measures, don’t forget about real world, physical threats. In many cases, it’s impossible for hackers to get into your system from the outside. However, if they get hold of a company laptop, hard drive or Blackberry, hackers can quickly get access. There’s a reason why Blackberry developed the nickname ‘hackberry’! Embrace the mobile revolution, but keep your personal devices safe and secure at all times.


Last of all, make sure you keep secure backups of all data and information. You can do this in a variety of ways. Start with physical, hard copies of sensitive or confidential information. Next, use a cloud storage system to keep essential information safe from hard drive crashes. Lastly, use a safe and secure hard drive. By using all three techniques, you’ll insulate your company from any problems.

After reading this post, how confident are you about the security of your business?

4 Ways Your Business Can Embrace The Mobile Revolution

Every business must adapt to the mobile revolution. Mobile technology is quickly becoming the most influential medium, and companies need to adjust. In the last twelve months, mobile internet access has surpassed traditional computer access. That means more web users are on a smartphone or tablet than a desktop or laptop. It’s a huge shift in the way consumers operate. As a business, if you’re not mirroring this trend, your days are numbered! If half of your customers are on mobile devices, you need to make sure you cater for them. The world moves quickly, and it’s not always easy for business owners to keep up. So today, we’ll show you how your business can embrace the mobile revolution. Let’s take a look.

1. Build a responsive website

A ‘responsive’ website means a site that adapts to whichever device loads up the web page. For example, the website will automatically recognise if it’s opened on an iPhone or a tablet or a laptop. It will instinctively display in the best possible way for that user. It’s a replacement for building an entirely separate mobile site, which was the old best-practice. Most professional web designers now build responsive websites as standard. It has become the bare minimum requirement. Make sure your company website is responsive.

2. Build an app

Many companies now have their very own app. So should you. Most mobile internet access takes place through an app, so it’s up to you to adapt to this technology. You need a strong presence in the app market. It’s now easier than ever to create an application. An app development agency can help you turn your plans into something real. You can get creative with your app too. Use it to offer your customers additional value, and take advantage of the mobile platform.

3. Reduce text

Adapting for the mobile world isn’t just about the mechanics. It’s not enough to build a responsive website and create an app. You’ve got to understand how your customers are using the mobile web. Studies show that mobile users have even shorter attention spans than computer users. Remember, you’re working with a smaller screen here, you’ve got a small space to make a big impact. Reduce your text to only the necessary component. Learn to say more with less.

4. Embrace social media

Mobile internet access revolves heavily around social media. The likes of Twitter, Instagram, and Facebook are reliant on mobile use. Indeed, they power it! As a business, you need to build a coherent social media strategy to encourage content sharing. Make sure your business is talked about on these platforms, and optimise your content for social sharing. We still speak to many companies that are wary of social media. It’s time to throw out this scepticism, and jump aboard the train while you still can. Social media is the essence of mobile communication, don’t get left out!

Mobile access is no longer a novelty or side-thought. It is a very real part of your business. Make sure you have a plan. Embrace the mobile revolution!

3 Steps To A Killer Online Presentation

The internet has created plenty of new business opportunities in recent years. A chance to reach a worldwide audience of millions has to be considered one of the most exciting. With a little ingenuity, your company could see phenomenal results. The key is to embrace technology with open arms.

Making an online presentation is one way to give yourself the edge over your competitors. You could stream live to the masses, or pre-record it as an online programme. Either way, this is an opportunity that no visionary would want to miss.

It sounds like a daunting task, but it isn’t. Here is an easy three-step guide to creating the perfect online presentation.
Fail to prepare and prepare to fail. It’s an old cliché, but it rings true with the idea of an online business presentation. The stage of planning is arguably the most important of all.

The key to your online presentation is to understand that a large portion of your audience will be speaking English as a second language. Making mistakes will confuse some of your viewers, and that could put them off. Using a grammar checking package is advised.

Similarly, you should remember that not every viewer will be an experienced professional. Some are using your video as an introduction to a subject. While you don’t want to patronise, it’s probably best to leave out overly complex jargon.

The actual content will be dependent on what you are talking about and what you are aiming to achieve. So we’ll leave that one to you.

An organised presentation doesn’t only look professional; it will help you through the process of presenting it. Slideshows and other visual aids can help move the project along nicely, serving as a huge benefit for both you and the audience.

Computer technology makes it easy to create a winning slideshow. If you are planning to pre-record, you can also cut to these items instead of staying fixed on your presenting. Besides, a lot of viewers will find it easier to understand visual information over auditory learning.

A presentation aimed at this demographic does differ from a real life audience, but the main principles are the same. Deliver information in a clear way and you cannot go far wrong.

The presentation is hugely important. While your video doesn’t need to be a Hollywood blockbuster, viewers won’t watch poor quality videos. When there are so many great affordable cameras on the market, you don’t have an excuse. Besides, there’s no point in taking on this challenge if you aren’t prepared to give it the full attention it needs.

Connection issues are the chief reason we’d suggest pre-recording rather than streaming live. This also gives the option to make edits later on or even add VT clips. For example, you could use projectors to hold a conference calls for added input from industry professionals. Those extra ideas could be the difference between a good and great result.

The other bonus of pre-recording is that you aren’t under as much pressure. Knowing that millions could be watching is scary. The opportunity to film in smaller segments, or reshoot after mistakes, is something every beginner should take.

The Best Ways To Reduce Spending On International Calls

Business owners around the world have to spend an astonishing amount of money to communicate with international clients. As everyone wants to make the highest profits possible, it is sensible to look for ways in which it is possible to make savings. We’ve listed some of the best techniques on this page. We hope this information will help you to understand that you don’t have to pay those premium call charges any longer. There are so many different alternatives to choose from that you will be spoiled for choice. However, you just need to research each of them before determining which is the best solution for your operation.

Use software like Skype

Video messaging software like Skype allows you to make international telephone calls for very cheap rates. You just need to buy some credits, and you are away. In most instances, the cost of the call will be no more than you would expect to pay when dialing a local number. Of course, you can also make the conversation free if you are connected to the internet. Just open a Skype account for your business and let clients know how to find you. It doesn’t cost anything to communicate via a video call so long as you have a good WiFi connection.

Chat on social media

The idea of talking with your clients and customers on social media websites might not seem that professional. However, some business owners are not in a good enough financial situation to complain. Again, you don’t have to pay anything to use the chat window on your Facebook account. That means you will save lots of money that could be better spent on more important tasks like growing your company.

Buy prepaid phone cards

Issa Asad changed the telecoms industry considerably when his company launched prepaid phone cards some years ago. He was probably the first one to realize that business owners needed a cheap way of calling clients overseas. Firms like his provide an excellent alternative to traditional services. Best of all? The cards only have a certain amount of credit, so it is impossible to overspend. That means you aren’t going to receive an enormous unexpected bill any time in the future.

Look for a business phone package

There are lots of telecoms companies out there that now offer standard business packages. In most instances, those deals will limit the amount it costs to call aboard. You just need to get in touch with all the top brands and ask them about their rates. At least one of them should have a package that suits your requirements.

So, there you have it. With a bit of luck, those four suggestions should help you to make some amazing savings. We all need to communicate with our clients, but that does not mean we can afford to break the bank in doing so. If you do manage to reduce your spending, feel free to let us know which concept worked best. We could use that information to help even more people in our next post.

Top 5 Misconceptions about Corporate Expense Management Software for 2015

When an organization has already chosen an expense management software, it becomes easy for them to dismiss the criticism of the program instead of having a look of what are the necessary ideas and strategies required to change it.  And when it comes to expense management software there are several myths and misconceptions that could cloud your judgement on every essential aspect of running a business. Thus it becomes very important to take your time and properly analyse your current expense management system optimizing your process and switching to another solution saving your time and money. Below given here are most common misconceptions about expense management software.

Current Employee Expense Management Software Program is not perfect but its fine: Just because your expense management software is not perfect, that does not mean that it can never be improved. Have a look at the different ways you are managing your expenses. Have a wish list created in order to know what are the things you would like to changes and what the weak points are. So if you find yourself paying exorbitant sums on the cooperate card interest and make you get worried about the credit risks then it is the right time that you switch to a new expense management software solution.

Having a new expense management software solution would not help you control the expenses: May be your business expenses are pretty lean and is not that bad. Having a closer look at how your employees pay their expenses would help you magnify the existing problems and find out the different ways where you could save. Prepaid business card solutions like the expense management software solution would allow you to have spending rules set for each and every business card that you choose, allowing the employees to spend money at the gas pump but not at restaurants.

Changing the current expense management software solution is time consuming and very difficult to implement: There have always been different ways of making an initial investment changing the way things are actually done. The finance managers, the office managers and accountants or others who are dealing with expense management software need to have enough knowledge on the new program, where the employees need to be informed about the procedures related to the software. However having an initial training and reformed expense management solution would make things easier saving your time and money creating a positive impact on your business.

Employee Expense Management Software is not a priority for my Company: Why wouldn’t your company want to save their money on all the expenses made. Having a good expense management software policies set and enforcing them should be the most important thing for your company. Your bottom line and your companies would thank you for this. And if your business relies on the employees who make a purchase through their own funds then the turnaround period for reimbursement is 3- 4 weeks.

It’s too expensive to switch for an Expense Management Programs now: The most important thing for an expense management program is to save your money and time spent by people processing the expenses. Optimizing the employee expense management software solution in your organization cutting down the major costs within the company, reducing the overall debt and protecting your business from the credit risk.

Indira Moola, Marketing Operations Manager at Expenzing, focused on growing expense management software open source product and communicates the value of identity to customers, partners, and the larger community by targeting specific markets through segmentation and analysis.

HIPAA Compliance And Securing Private Patient Information

The Health Insurance Portability and Accountability Act (HIPAA) has established standards for the protection and management of private patient information. There are severe criminal and civil penalties for violations of the compliance regime, and healthcare practices and those who do business with them which provides direct or indirect access to data are caught by the provisions of the legislation.

In broad terms, anyone who has access to, manages or works with Protected Health Information (PHI) must put in place physical and network security measures, and also establish process security too.

Those covered by the law are divided into two categories. Covered Entities (CE) are any person or organization which provides treatment, pays for treatment (in the form of an insurance company, not a private individual), or operations in the healthcare industry. The second class are referred to as Business Associates (BA) and these include any entity with access to PHI, supports treatment of patients, or is involved in payment processing or healthcare operations. The law has been extended to catch subcontractors and close business partners of BAs too.

HIPAA has two main rules: the Privacy Rule and the Security Rule. The HIPAA Privacy Rule covers the issues surrounding capturing, saving, access control and the sharing of any patient information. The HIPAA Security Rule lays down national standards enforced at federal level, for protection of PHI at all stages of its life, from access, storage, transmission across networks and how it is maintained.

The Security Rule lays down broadly framed provisions for what a CE or BA must put in place, however there is a great deal of discretion allowed. For instance, you must protect against a “reasonably foreseeable risk” to PHI, and your protective steps must also be “reasonable” – what this means in practice is that CEs and Bas are exposed to the capricious nature of what is meant by “reasonable.”

Ensuring HIPAA compliance using an in-house team is exceptionally difficult for all healthcare providers and their associates, unless they are extremely large and have the resources and budgets to build a compliance team of specialists. In practice, most healthcare providers subcontract out HIPAA compliance efforts to specialist providers who are experienced in such matters, and this is a more secure and cost-effective manner in handling it.

Note however, simply by engaging a third-party professional does not in any way remove liability for compliance with HIPAA from the CE or BA. This makes it absolutely essential that who the third-party providers is, that they have the skills, experience, stability and technical understanding of HIPAA and the steps required to protect your patient information and data.

HIPAA provides for both criminal and civil penalties ranging up to one year in jail and $1.5 million fines, but this is per violation, or per individual patient record that is compromised. Fines are very common for violators, including first-time offenders, however the ability to impose crimpling fines on a healthcare professional or practice can put them out of business. More than this, major offenders are placed on the Wall of Shame maintained by the Department of Health and Human Services (HHS) website.

Jenny Ford writes on healthcare and IT issues and is currently working on a Whitepaper covering HIPAA and data protection for Swift Systems.

Are Magnetometers Used In Space?

Magnetometers are a growing tool for geologists and mineral explorers on Earth. They are part of a suite of tools used to find minerals. However, in space, they are the tool for orienting spacecraft. In fact, space travel and even satellite launches would not be possible without them. For interplanetary exploration they’re even more important, as they give vital clues about the geology of other planets. Even around Earth, they can be used to help predict the weather.
Why Magnetometers are Necessary?
Magnetometers are needed in space to detect attitude, or the angle of the spacecraft relative to a nearby planet. Ordinary aircraft can find this using gravity: a weighted ball rotates to keep the heaviest point at the bottom, showing the attitude on the top of the ball. In orbit this technique is useless: everything on the ship is in freefall, so the weighted ball will not rotate to match the craft’s attitude.
Without an exact altitude measurement, astronauts and computers are not able to execute their full burns at the proper angle, resulting in erratic and dangerous orbits. Without an attitude meter, it would be functionally impossible to safely deploy any satellite, let alone satellites with precise orbital needs, like the GPS network. Early rocket scientists puzzled over this problem until the Soviet space program discovered that a fluxgate magnetometer could use magnetism to precisely calculate the attitude of a spacecraft relative to Earth. This uses as a reference point the magnetic field of the Earth, which exerts forces on magnetometer coils up to six million kilometres away from the surface. 
This magnetic field exerts force in a parallel direction to the Earth’s surface, and thus can work just like gravity for determining attitude. Later spacecraft took this idea further and developed magnetometers that could also return altitude, even in a vacuum.
More precise magnetometers have been since been used by NASA to calculate spacecraft attitude and altitude not only relative to Earth, but also relative to other planets like Mercury and Venus.
Magnetometers and Planetary Exploration
Since the early days of spacecraft design, magnetometers on Earth have come a long way, finding uses in mineral and water prospecting. NASA has applied these advances to their interplanetary explorations. Magnetic surveys provide information about ice and minerals below the surface of planets, and are essential in determining if space stations could ever be viable on our solar neighbours.
In 1996, NASA launched the Mars Global Surveyor (MGS), an unmanned orbiter intended to survey Mars and locate ideal drop zones for rovers. The MGS completed a magnetic survey using a fluxgate magnetometer that revealed interesting anomalies below the Martian surface. NASA hypothesized that some of these anomalies are underground ice packs, and believes that there is enough ice on Mars to cover most of the planet in water.
Magnetometers and Weather Satellites
Magnetometers such as vector magnetometers, scalar magnetometers etc have a more practical use: predicting “substorms”, magnetic storms in the upper atmosphere that discharge heat and electricity to lower atmosphere levels. These can affect devices, including vital ones like aircraft navigation systems, on the surface, and may affect weather patterns. Fortunately, NASA has developed a magnetometer for use by weather satellites that alerts meteorologists to the conditions preceding substorms.
Magnetometers are a vital and growing part of space travel. They will continue to be useful in helping us better understand both our own climate and the potential of other planets.
