6 Tips to Keep the Internet of Things Secure

The Internet of Things (IoT) relates to all those smart devices which can connect to your network and communicate with it, but how do you make the IoT safe?

We have smart devices not just at home, but also within our businesses and it’s no surprise to hear that it’s estimated up to 8.4 billion smart devices will be connected in 2017. Naturally, with such a huge number of devices accessing networks, it’s not surprise that they’re proving to be highly interesting to hackers.

As our business life is becoming more and more digital, the need for the IoT is increasing just as rapidly, that’s why I’m going to share 6 tips to keep the IoT secure.

1. Understand What’s Connected

It’s important that you know which devices are regularly connected to your network. By understanding which devices offer a route into your network, you’re able to take preventative measures to help safeguard against any vulnerabilities. Make sure that a database is kept and regularly updated to include any new hardware so that you can fully understand the reach of your IoT.

2. Keep IoT Devices on a Separate Network

If one of your IoT devices is compromised by a hacker then this represents a threat to everything on that network, so it’s important that you segment all your IoT devices onto a separate network. In the event of an IoT device being hacked you can then limit the data on offer to the hacker.

3. Don’t Leave Devices Connected for Longer than Necessary

It’s impossible to hack a smart device which isn’t plugged in, so to completely minimize the risk it’s highly recommended that smart devices are disconnected from the network when they’re not being used. This is a good security practice that needs to be communicated to all employees as anything can be hacked be it a printer or a webcam.

4. Always Install Firmware Updates

As with any other piece of hardware or software, firmware updates for smart devices need to be installed as soon as possible. Not many people are aware of the security risks associated with smart devices, so firmware updates are often ignored – this is why hackers are starting to target them more and more often. So, once you see that update request, make sure you click it.

5. Limit Personal Device Usage

99.9% of the population appears to have a smartphone, so this means that almost all of your employees will be bringing a smart device to work every day. And, to ensure that they can keep up to date with Facebook, they’ll be piggybacking onto your company WiFi to create an internet connection. Therefore, it’s important that you limit personal device usage or, at least, create a sign in method which uses company email addresses.

6. Password Protect Everything

Finally, you must make sure that you password protect every single smart device within your business. As previously mentioned, it’s easy to assume that a printer is never going to get hacked, but it happens. By establishing a set of passwords (all different of course) for all your smart devices you’re putting that extra layer of defense in front of your business. And the more defenses you have, the less attractive your network becomes to hackers.

5 Most Important Considerations of a New PC

Dec 2014

Whether you’re buying a new PC for the office, your business or personal use, here are the features you should focus on to get the most bang for your buck.

We’re going to highlight the 5 most important features to look for in a new PC. But before we delve onto our list of five important features, let’s discuss a preliminary checklist:

What are you going to use your PC for? You’ll need to determine if you’re going to be using to for work, where potentially, data protection and backups will be crucial. Even if it’s for personal use, you’ll still want to consider securing your data and backing up your documents, photos, emails and so forth, periodically.

What software will you use? General word processing and other similar office applications are not so resource intensive. On the other hand, if you are planning on using a resource hungry program, such as a graphic design software, or anything that requires a PC with a fast processor and plenty of memory, you’ll need to take note of the minimum specifications. Even the minimum specifications on a PC for any given software will not guarantee the best performance.

Optical CD drive, anyone? If anyone remembers the phasing out of the floppy disk drives in the mid nineties, the same thing is happening to optical CD drives. They are fast becoming a legacy component, thanks to this age of digital downloads, portable USB storage and online video streaming sites. You’ll need to consider whether you’ll want one with an optical drive or not. Alternatively, you can purchase an external CD/ DVD drive if you really needed one for any intended purpose.

With all these preliminary requirements covered, let’s now dive into our checklist for the 5 most important features to look for when shopping for a new PC

Customer support.

When it comes purchasing something new, you’ll want peace of mind and know that you can call a phone support line and have a warranty to replace faulty parts. Also, some PCs may require registration in order to activate its warranty, so if you’ve any questions, you know where to call.

Opt for reputable brands.

Brands like Dell, HP or Lenovo, have a well-established community which also means that finding replacement parts is easy and less of a struggle.

Double-check the preloaded software.

Never feel too afraid to ask the sales rep about the software that comes pre-loaded with the PC. If you need a full version of Office software, make sure it has that and not just trial versions or 90 days’ worth of the full version. This is important if you heavily rely on using such software, as you won’t appreciate a break in your productivity whilst acquiring the full version!

Watch out for unnecessary software.

Be sure to find out if it comes loaded with junk software from the manufacturer pressuring you to sign up to their services. This is often a sales pitch, and from our experience, a complete waste of time, money and digital space! Just focus on what you really need and stick to your requirements.

Check the PC’s specifications.

You’ll want to look for a PC that has a fast processor and plenty of RAM. Many store sales brag about sub $300 systems, when in reality they are cutting corners like memory and processor speed.

Too often people have been mis-sold the wrong type of PC and software that comes with it. Don’t be afraid to ask how systems you are comparing stack up against others in the market.

Should You Update Adobe Flash?

Aug 2014

Adobe Flash player is an indispensable part of web browsing. Whether you’re watching Youtube videos, gaming online, or streaming videos, Adobe Flash will likely be necessary so be sure to keep it secure.

What is Adobe Flash?

According to Wikipedia:

Adobe Flash (formerly called Macromedia Flash and Shockwave Flash) is a multimedia and software platform used for creating vector graphics, animation, games and rich Internet applications (RIAs) that can be viewed, played and executed in Adobe Flash Player.

In other words, when you view multimedia through your web browser such as videos, music or animations, there is a good chance that it is using Adobe Flash.

What’s the risk?

The increased functionality flash player gives you also comes with risks. Flash player gives criminals almost as many opportunities to compromise your system as Java. If these risks are not addressed, you could be subject to exploits such as one that allows attackers to mimic a website to obtain your confidential information or even cause a denial of service by corrupting your memory.

Keeping your flash player updated to the latest version is the best way to plug these security holes that jeopardize your system. Fortunately, if you web browse with google chrome, your flash player is automatically updated.

How to update Adobe Flash player

1.) Go to Adobe’s website to check if you have the latest flash player installed.

Click Check Now to see if you have the the current version. If you do, congratulations. If you don’t….

2.) Go to the download link in step 2.

Click Download now to download the file. Before doing this, make sure NO extra programs are checked for you to download. Frequently, this will be McAfee as shown below:

Immediately uncheck the box next to Yes, install McAfee Security Scan Plus. You do NOT need this program, and it will make Windows run slower if you already have an antivirus program running.

3.) Follow the installation instructions on the download page.

4.) Enable Flash Player on your browser. The links for the instructions for each browser can be found on Adobe’s website.

5.) Verify if Flash Player is installed by checking the animation on Adobe’s website. If you see clouds moving, you have installed the player. If you don’t, try refreshing the page. If that still fails to produce moving clouds, go through the installation steps again.

Why It’s Important to Update Java

Aug 2014

Java is required by many applications and websites to work properly. It can also be exploited by criminals. Here’s why you should keep your java up to date.

Many business users need it to run custom or legacy applications. Java is not just for gamers. It is used by countless business applications.

Java Security Risks

As recently as January, hackers were able to exploit a security hole in Java to serve up malware to hundreds of thousands of systems per hour.

It is because of these security holes and many others that Java must be updated frequently.

Java often uses your web browser to access websites, and your web browser is the most vulnerable attack surface for hackers. Therefore, not updating Java religiously is playing with fire.

How to Update Java

First, find out if you have the latest version here.

Click the red Verify Java version box to allow Oracle’s website to find out if you have the latest version installed. If you are given a prompt stating Allow the Java plugin for your browser, click to allow it. Next, another prompt will likely appear as shown below:

Click Run to allow the application to run. If you have reached this stage, you have Java, though not necessarily the latest edition. If you have the latest Java, you should get a window telling you Congratulations with an accompanying green check. If you don’t have the latest Java, you should see a screen that looks like this:

Click Click Download Java Now to get the latest version of Java.

Click the red Agree and Start Free Download to get the newest Java for your system. The progress of the download should appear at the bottom of your browser. It will finish when no time appears next to the download.

Click the .exe file to kick off the installation. You should promptly close your browser to avoid any roadblocks or conflicts.

When the security warning appears, click Install to permit the latest Java to be installed.

On the Welcome to Java screen, click Install again to allow the installation to proceed. At some point during the installation, you will see the following window:

At all costs, do NOT check the Install the Ask Toolbar and make Ask my default search provider option. The Ask Toolbar is completely unnecessary and makes your computer more vulnerable to infections. Click Next to allow the final steps of the installation.

After the green progress bar reaches the end, you will be directed to Oracle’s website where you will again see the following:

As before, click the red Verify Java version button. Once again you should click Allow to enable the website to see what Java version you are running. Also, click Run in the following window to enable the test.

If you have the latest Java, you will see the following window:

If the website still tells you your Java is outdated, go through the earlier steps starting with Download Java. If you have already downloaded and installed the latest Java and you get the outdated message, simply closing and reopening your browser will often correct the problem. Go back to Oracle’s website to verify your Java version.

Jul 2014

To maintain a secure and functioning system, it’s important to keep your system up to date. Here’s how you can check for updates in Windows.

It’s easy to check

In Windows 7 or Vista, click the Start button and, in the search box, type Windows Update.

In Windows 8, drag the mouse to the right edge of the screen, click the search charm that appears, and type Windows Update.

Click Windows Update when it appears on the menu. You should then get a screen that looks like this:

To review the updates that are available, you can click on the blue text representing the optional and important updates respectively.

The next screen allows you to check the boxes of the updates you wish to install.

We recommend that you install all the important updates and almost all of the optional ones. The optional update we counsel against is the Bing bar, which introduces a toolbar that you definitely do not need.

Once you have checked all the updates you want, click Install to go back to the previous screen where you click Install updates to get the process started.

Set Windows to install important updates automatically

You can check this setting on the same screen on which you installed Windows updates. Look to the left margin, and you should see a link to Change settings.

For Important updates, use the drag- down menu to Install updates automatically (recommended).

Installing important updates automatically will keep the critical security fixes off the back burner and readily available to ward off viruses.

For more about updates or other issues affecting your PC, consult your local IT professionals.
