Currently scheduled for October 11, 2018, the Internet Corporation for Assigned Names and Numbers (ICANN) plans to change the cryptographic key that helps to secure the internet’s Domain Name System (DNS) by performing a Root Zone Domain Name System Security Extensions (DNSSEC) key signing key (KSK) rollover.
DNS-Based Threats: Cache Poisoning

We’ve all seen the check boxes. They’re hidden at the bottom of webpages. You can’t ignore them, but sometimes you forget they are there. They offer to send you deals and coupons. Some even offer to connect you with their partners for similar benefits. Do you check the box?
In these situations you are given a choice of how you want your personal information used. These sites provide the option to trade some of your personal information for a future benefit. If you decide to opt in, your personal information will be transferred, traded or sold to others, and in exchange you will receive something in return, i.e., 10 percent off your next purchase, advance notice of upcoming events, a free gift, etc. If you opt out, you will receive nothing. Regardless of the return, you were given a choice; opt in and receive a benefit for the use of your personal information, or opt out and be content that your personal information won’t be sold.

Your social activities with friends and family are chronicled on Facebook. You alert the world of your immediate thoughts on Twitter. You even choose to provide your address and credit card information when buying things online. All of this personal information about you is deliberately posted and collected with your consent.
