So what needs to be done for DNSSEC to be deployed on a large scale? We’ll discuss the business reasons for, and financial implications of, deploying DNSSEC, from staying ahead of the technological curve, to staying ahead of your competition, to keeping your customers satisfied and secure on the Internet. We’ll also examine some of the challenges operators have faced and the opportunities to address those challenges and move deployment forward.
2. DNS Refresher
● DNS converts names (www.gumtree.co.za) to
