Mobile devices, such as smartphones and laptops, have changed the landscape of business organizations everywhere. Nowadays, businesses arm their workers with these devices in the field, making mobile performance and connectivity highly essential. Optimizing IT systems for mobile workers isn’t easy, but there are a few simple tricks you can try.

The ability to manage the workforce out in the field requires a modern support infrastructure called mobile performance management. It includes the top five tips to keep field workers connected: optimizing traffic, applying control, measuring performance analytics, simplifying data security, and identifying the root cause of connectivity issues.

Optimize

Although the latest apps on the market can maximize productivity for the mobile workforce, these apps come with a certain risks: stability issues that could lead to the apps crashing while out in the field. If you are your company’s IT decision-maker, be cautious of untested apps, and consider blocking heavy bandwidth apps to streamline data flow when signal strength is weak.

Control

Another thing you can do with mobile performance management solutions is blocking personal apps and unsafe WiFi networks. Both of these create serious security risks that could lead to costly data theft or loss.

Analyzing performance

Field workers mostly rely on GPS location data for more efficient scheduling, route-planning, and effective control of fuel consumption. This is possible only if there are reporting tools that confirm that the GPS capability is working. Performance analytics show you what mobile workers are experiencing, gaining access to robust data, network and app usage reports, inventory analysis, coverage maps and device maps as needed.

Simplify security

IT should tightly restrict access without making security complicated for mobile workers. IT administrators need to create a highly flexible and programmable secure mobile strategy. You must be able to restrict which apps can access company data and remotely wipe data from the device if it is lost or stolen.

Identifying the root cause of connection issues

Obviously, field workers are not IT experts, so organizations need to be fully prepared for connectivity issues involving their mobile devices. Organizations of all sizes should be able to afford remote diagnostics to gather complete troubleshooting information to allow IT to identify the root cause of the problem quickly, without relying on workers, who have no idea about how to run tests and answer questions regarding these issues.

For any organization with workers in the field, the ability to implement performance management structures and policies is a must. For other tips on how to keep your employees connected, engaged, and efficient, give us a call and we’ll be happy to advise.

For ages, most people assumed that setting a strong password on their WiFi router was enough to prevent cyberattacks, but recent events prove otherwise. Two Belgian security analysts have found a serious weakness in WiFi networks, called KRACK, that puts your wireless devices in danger.

What is KRACK?
Simply put, KRACK, short for ‘key reinstallation attack,’ allows hackers to bypass WPA2 — a security protocol used by routers and devices to encrypt activity — and intercepts sensitive data passing between the mobile device and the wireless router, including login details, credit card numbers, private emails, and photos.

In extreme cases, KRACKed devices can be remotely controlled. For example, hackers can log in to your surveillance systems and shut them down.

What’s worse, Internet of Things devices — like smart thermostats and IP cameras — rarely receive security fixes, and even if some are available, applying patches are difficult, as these devices tend to have complex user interfaces.

The good news, however, is you can do several things to mitigate the risks.

Download patches immediately
According to recent reports, security patches have already been released for major platforms, including iOS, Windows, and Android. Router manufacturers such as Ubiquiti, Mikrotik, Meraki, and FortiNet have also issued firmware updates, so make sure to install them as soon as possible.

Although IoT patches are rare, consider getting your smart devices from reputable vendors that push out updates regularly. It’s also a good idea to contact a managed services provider to install the updates for you.

Use Ethernet connections
Some wireless routers don’t yet have a security patch, so while you’re waiting, use an Ethernet cable and disable your router’s wireless setting. Turn off the WiFi on your devices as well to make sure you’re not connecting to networks susceptible to KRACK.

Stay off public networks
Free public WiFi networks — even ones that are password-protected — in your local cafe should also be avoided because they usually don’t have holistic security measures in place, making them easy targets for cybercriminals.

Connect to HTTPS websites
If you do need to connect to a public WiFi hotspot, visit websites that start with “HTTPS,” and stay away from ones that are prefaced with “HTTP.” This is because HTTPS websites encrypt all traffic between your browser and the website, regardless of whether the connection is vulnerable to KRACK

Hop on a Virtual Private Network (VPN)
You can also use a VPN service to hide all network activity. Simply put, VPNs encrypt your internet connection so that all the data you’re transmitting is safe from prying eyes.

Although the potential impact of a KRACK hack is devastating, security awareness and top-notch support are the best ways to stay safe online. Want more security tips? Contact us today.
