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.

Top 5 Reasons To Upgrade Your Network

Computer NetworkYou have worked hard and your business has grown at lightning speed. Now that you’re sure everything is on track to succeed but are not sure of how IT can provide a meaningful benefit to you business.

Here are the top 5 reasons to call in the networking professionals to check out your IT and network so that it is running and improving productivity in your business.

Speed: Transferring a large file across a network can cause lost productivity as time is lost waiting. As a small business this lost time was negligible, but as your business has grown, so has the wait time. It may only be 5 minutes a day but with roughly 260 work days in a year, that 5 minutes a day turns into 21 hours. The impact of this lost time causes breaks in workflow and concentration that can almost double the time off-task. To speed up things employees store files on their local machines which aren’t backed up leading to other issues.

Efficiency: Almost every business requires employees to share files. You may have gotten by with a simple setup and minimal or no security, but as your workforce has grown, so has the load on the network. Each computer, storage drive, printer and other networkable device adds further load onto your network – resulting in a slow transfers, errors, time off task, and even faster hardware failure. A professionally designed network will give your employees a central file storage location, with the added benefit of automated backups. No more losing hours of valuable effort or surprise file corruptions, just a scalable, secure server with smooth and efficient transfers.

Collaboration: Employees often need to work together on the same documents. Previously, this required them to take turns, waiting until someone else was finished before the file was available. With a modern network setup, collaboration becomes an organic, profitable way to work. Employees don’t even need to be in the same physical location, opening up opportunities for remote collaboration.

Confidentiality: Every business needs to keep at least some data confidential. Whether they are trade secrets or accounting data you need to have complete control over who sees what. Your IT professional will be able to establish a setup that meets your business’ unique needs. Perhaps the CEO is able to see everything, sales staff can only see sales data, and accounting can only see accounts. Access can be set based on name, department, role or go further and require passwords for certain folders.

Flexibility: Expand your connection flexibility with wireless networking for employees who are required to roam within the building, Virtual Private Networks (VPNs) for those working at home, or even cloud based file sharing for those who work offsite or in different locations. A good network setup will always support the way your business works, now and in the future.

Your ability to securely share, store and transfer files will be one of the key contributors to continued growth. The speed, efficiency and flexibility you build into your processes now will save you time, money and future frustration. It’s time to celebrate how far your business has come by looking to the future, with a robust, scalable network that supports your vision.
