Secure Wi-Fi is important. But secure IoT is vital.

After years of using hotspots, many of us who connect our PCs via Wi-Fi away from home have learned the difference between secured and unsecured networks – and are now smarter and safer when we get online at the café or airport. But our connection habits are changing. In 2016, average smartphone usage grew 38 percent, and more mobile phone traffic – nearly 60 percent – was handled by Wi-Fi hotspots than by cellular networks, putting our phones at risk, too. Add the proliferation of Internet of Things (IoT) devices, and today’s Wi-Fi threats can outpace even the tech-savviest among us. Because we have greater mobility and connectivity, hackers are motivated to take advantage of our need for both.

Protecting real trust and truth in a virtual world

People often trust their social media contacts more than traditional advertising, and more readily believe everything from restaurant reviews to political opinions when it comes from a social network. An amusing or tragic anecdote that may not be representative of any trend has a better chance of going viral than a well-reported story with lots of analysis and facts. As always, there are marketers, abusers, propagandists, and outright criminals who are quick to exploit these psychological biases. The person who attacks you over a political tweet may be a paid troll or a robot. The spam you ignored in your inbox is now served into a trusted social media feed. The phishing attacks and malicious links you’d never click on in an anonymous email may now appear as a recommendation from a good friend, or a celebrity you admire. These attacks may even be customized by AI to target you perfectly, the way you get shopping or movie recommendations.

A cybersecurity primer

History teaches us that everything changes, and that’s particularly true when it comes to cybersecurity where a vulnerability, accidental or malicious, can put a business at risk any time, any where. While cybersecurity must address the core functions — Identify, Protect, Detect, Respond and Recover — in a holistic manner, what are the processes, practices, hardware and software that when combined and integrated together can provide effective cybersecurity? The following is not a definitive list, but it does cover the basics required to better secure your information assets.

Detection: What you don’t know will hurt you

One of the realities of today’s cybersecurity threatscape is not if you will be breached, but when, and how often. As good as cybersecurity is becoming – i.e. prevention solutions provide a 99.9 percent or higher detection rate for common malware – effective cybersecurity depends upon three pillars –  prevention, detection and resolution – with the latter two required to address those situations where prevention isn’t enough.

Out of all the cybercrimes from malware to social engineering, the creepiest has to be a stranger watching your child through a webcam or baby monitor in their room. As this year’s Mobile World Congress starts in Barcelona, Avast researchers reveal that half a million smart devices in the city, including webcams and baby monitors, are currently vulnerable to cyber attack.

Find out if your home network is vulnerable with Wi-Fi Inspector

That little black home router with the funny antennae and shiny lights could be part of an army of devices conscripted to take down the internet. It sounds dramatic, but regular people’s internet-enabled devices – routers, webcams, printers, and so on – were used in a massive online attack that shut down a huge part of the internet for hours one Friday morning last October. With the number of connected devices estimated to reach 50 billion by 2020, you can be guaranteed that cybercriminals will attempt it again.
