Challenges in Government Cyber Security
Challenges in Government Cyber Security

Has cyber security been a challenge in your government organization? Are you looking to improve your government's network security? Learn more about how to improve your government organization's security by viewing our on-demand webinar!

Warning: If your device uses WiFi, it's at risk!
News broke today about the Krack Attack, a new cyber threat that can decrypt and potentially view everything users are doing online. The Krack Attack preys on a weakness in WPA2 protocol. Hackers near the vulnerable devices (Android and Linux are at greatest risk) can retrieve sensitive user data and information.
Steps to Protect:
1. Apply patches as they become available. For phones and computers, the patches will come in the usual update format. For wifi routers, the manufacturer's website will have the patches.
2. Don't use public WiFi, especially for sharing or sending any sensitive information.
3. Double check that you are browsing with HTTPS. If you are unsure, install this plug-in to encrypt your communications with major websites and make your browsing more secure. https://www.eff.org/https-everywhere
4. Otherwise, use Ethernet.

Amazon recently filed a patent for a system wherein while someone is shopping inside of a store, and using that store's wifi connection, the store owner is able to inspect the wifi packets to see if a competitive product is being viewed and then issue a "control" action in response.

Basically if you want to price shop while inside of a retailer, they'll be able to block the action from happening.

With mobile data plans so affordable these days, combined with the great speeds 4G provides, I don't get why people still auto connect to public wifi hotspots at all? They're fraught with hackers and an easy way of getting yourself infected with something.  

Never use them myself so the expensive patent application is a waste of money on Amazon's part so far as I'm concerned.

In most of the big box stores, I lose my LTE signal and have to use their wi-fi. I use a secure vpn when connecting, but your average consumer just blindly connects.
