KRACK & WPA Vulnerability: 3 Ways to Enhance Wi-fi Security

Security researchers recently announced vulnerabilities in WPA2 encryption, practically used everywhere since WEP went the way of the dodo. The implications of the discovery are clear:

  • The attack works against all modern protected Wi-Fi networks
  • If your device supports Wi-Fi, it is most likely affected

This means threat actors are able to see your traffic, hijack connections, and perform man-in-the-middle attacks. So, is WPA2 also going the way of the dodo? Not exactly. Manufacturers are rolling out fixes – they were notified as early as August.

But it’s time for us to see wireless as a shared medium. Where a cable allows for a direct, physical connection, the nature of wireless is that it’s accessible to everyone. On a shared medium, you want to know who exactly is on it, and give them the appropriate level of access. No baddies spying on you or impersonating your users.

Here are 3 ways to enhance your Wi-fi security:

Tunnels shield you from the elements

Instead of relying only on traditional WPA2, opt for best in class security – custom ciphers with a dedicated SSL VPN connection. Attackers see only an encrypted tunnel of traffic, no eavesdropping allowed

Are you who you say you are?

Look for a BYOD-ready network access control solution with automated, self-service onboarding of devices that give only authorised devices access, and intelligently restricts the unauthorised

Host checking comes in handy to ensure end points are in compliance before they enter your network. Virus definitions? Latest patches? Peace of mind? Check.
