Nominum CNS Administration

Lecture and Lab, 1 day

Nominum's Caching Name Server (CNS) is the world's fastest caching name server. It uses adaptive algorithms that deliver superior DNS query caching performance and high service availability. CNS has the latest features to prevent Denial of Service (DoS) attacks and is core to a network infrastructure resilient to attacks from worms, viruses, and hackers.

This one day course provides a comprehensive introduction to Nominum CNS and is essential for DNS administrators who wish to deepen their knowledge of the features of CNS, to configure CNS to deliver the fasted DNS responses to their customers, and to understand how to use CNS to make their network more secure. Students will learn by doing via Nominum's hands-on, high-feedback approach.

Please see our training schedule for information on class dates.
