On October 16, 2017, Belgian security researchers made public their findings that demonstrated fundamental design flaws in WPA2 that could lead to man-in-the-middle (MITM) attacks on wireless networks.

Named KRACKs, or key reinstallation attacks, this technique can theoretically be used by attackers to steal sensitive information from unsuspecting wireless users leveraging these flaws in the WiFi standard. Based on their research, CERT issued a series of CVEs to address this flaw, and most vendors affected have issued patches as of this writing.

Depending on the terms of your purchase, every year you’ll need to pay a maintenance fee to renew the license on your SonicWall. When that time comes around, we often see confusion from customers on why they need to pay to continue using an appliance they already own. After all, you don’t have to pay a license for a refrigerator, stove or toaster, right?

Well, the simple fact of the matter is a SonicWall isn’t a static appliance like a refrigerator or stove, and that’s a very good thing; threats are constantly evolving.
