The Challenge of Secure Wi-Fi 

The Challenge of Secure Wi-Fi 



It’s fair to say that we have all been spending less time jumping onto Wi-Fi hotspots at cafes, hotels, airports or company guest networks, over the last sixth months. But as lockdown measures were eased, we saw more people looking for a change of scenery in coffee bars and pubs offering workspaces.


Whether at home or out and about, Wi-Fi has become something we have come to rely on for work and pleasure, while mobile operators increasingly use ‘hand-over’ to W-Fi networks as a way of meeting demand for capacity. But our need for anytime, anyplace connectivity, means that we are inclined to jump onto Wi-Fi hotspots with only passing concerns about security, creating a perfect hunting ground for attackers.


Hotspots that require no passwords and don’t use encryption mean that anyone with a simple packet sniffer can potentially pick up your login credentials to sensitive websites and applications. Hotspots that require a ‘password of the day’ are encrypted but a sophisticated Wi-Fi attacker can decrypt the traffic using easily available Wi-Fi hacking toolkits. And of course, the risks from hotspots are compounded when access devices are personal and unmanaged by Mobile Device Management (MDM) systems that can enforce security policies. Anyone deploying a Wi-Fi network should be aware of these top eight Wi-Fi risks.


Wi-Fi Password Cracking


Wireless access points that still use older security protocols such as WEP, make for easy targets because these passwords are notoriously easy to crack.


Rogue Hotspots


Nothing physically prevents a cyber criminal from enabling a foreign access point near your hotspot with a matching SSID that invites unsuspecting customers to log in. Users that fall victim to the rogue access p ..
