Traveling With Technology?

Business trips can be stressful at the best of times. Whether you’re off for an overnight visit to a client, a few days for a training session or a longer business conference there are certain things you need to keep in mind:

Be careful with free WiFi
Many hotels have free WiFi along with libraries, cafes, bookstores and other public areas. Unfortunately, that convenience can come at a huge cost. The wireless network you use to check your email while relaxing with a latte could be operated by someone up to no good or even have been taken over by a hacker.

Using a VPN can help as well as only using secure websites (make sure the sites you visit have the little HTTPS lock).

Connect via your cell phone
The wireless networks in hotels are notorious for being slow or insanely expensive. You may find that you can use your mobile as a wireless Internet connection. This means that you connect your laptop to your phone via WiFi or cable and piggy back on its mobile internet connection. Most carriers and phones allow this – but not all. Importantly, if you’re in another country it can also be worthwhile getting a local sim card for your phone rather than paying expensive roaming charges.

Don’t forget power adapters
You’ve seen it before…people asking to borrow your charger and huddling around in groups until their device has enough juice to get them through a few more hours. Remember it is only funny when it happens to other people so make sure that it doesn’t happen to you. Be sure to pack your correct power adapters and cables, along with any plug/voltage converters required to match where you are going. It is also worth carrying your USB charging cables on your person or carry on luggage, as many planes and airport shops now offer a place for you to plug in for a quick boost.

Have plans for being offline
Sometimes you simply can’t get online, which will do you no good when you’re checking into your hotel and all your booking details are tucked safely away in your email acount. You can print out essential travel and business details on paper, but if you have a lot or don’t want to carry them, you can also save them to a document on your phone or computer. Emails can be copied and pasted into a MS Word document, or you can print them to PDF by pressing Print > Save to PDF (or similar). Many apps also have an offline mode that allows you to store the information on your computer, including Evernote and Netflix.

How The ‘KRACK’ Wi-Fi Security Issue Affects Us All

WPA2 KrackedThe invention of Wi-Fi or wireless networking has been a dream come true. We can use our laptops and tablets anywhere in the office and our phones are using the main internet connection instead of sucking down data on the 3G / 4G network. It is essentially the backbone of the smart tech boom for home and business alike. Most Wi-Fi networks are password-protected with an encryption called “WPA2” and up until now this has been safe and secure.

Recently, a security flaw called KRACK (The Key Reinstallation AttaCK) was discovered. KRACK allows hackers to break into Wi-Fi networks – even the secured ones and your wireless networks are possibly vulnerable as a result.

How KRACK works?

KRACK doesn’t work via a problem with your device or how it was set up as it is an actual issue with the Wi-Fi technology itself. The attack gets between your device (eg computer, tablet or mobile phone) and the wireless access point (eg modem / router) to reset the encryption key so hackers can view all network traffic in plain text. Since just about everyone relies on Wi-Fi so much, this might mean hackers have a front row seat to your credit card numbers, passwords, confidential files, emails and more.

NOTE: The hacker needs to be in physical range of your Wi-Fi network to exploit this flaw and it doesn’t work remotely like other attacks we’ve seen recently. Given that most Wi-Fi networks extend well past your own home/business walls, this is small comfort, but important to know.

How to protect yourself

Run your updates: Software updates are being released which fix the flaw. Microsoft has already released them for Windows and Apple has one coming in a few weeks. So please take a few minutes to make sure you’re up to date with all your patches on any device that uses Wi-Fi (your smartphones, laptops, tablets, PCs, game consoles, etc). Unfortunately, some devices may be slow to get an update (eg Android phones), or if they’re older, may not get an update to fix the issue at all. If possible, consider using a cabled connection on those older devices or upgrade to one with support. With smart phones consider using data on the 3G / 4G network instead of Wi-Fi.

Be very careful with public Wi-Fi: While your local business center, library or school campus should have expert IT professionals keeping guard over security, it is a very different matter at your local coffee shop. It is unlikely small locations such as this will be on top of security patches. Remember, a hacker exploiting this flaw only needs to be in the same Wi-Fi area as you, so be careful you don’t give them an opportunity to grab your precious data.

Check your browser security: Before sending anything private over the internet, check that you are using a secure HTTPS site. You’ll know these by the little padlock you see next to the URL, and the address specifically begins with HTTPS. Major sites like Facebook, Gmail and financial institutions already use HTTPS.
