DNS/DNSSEC (5 days)

Synopsis

The Domain Name System (DNS) is a critical part of Internet infrastructure and the largest distributed Internet directory service. DNS translates names to IP addresses, a required process for web navigation, email delivery, and other Internet functions. However, the DNS infrastructure is not secure enough unless the security mechanisms such as Transaction Signatures (TSIG) and DNS Security Extensions (DNSSEC) are implemented. To guarantee the availability and the secure Internet services, it is important for networking professionals to understand DNS Security concepts, configurations, and operations.

This course will discuss the concept of DNS Security in detail, including mechanisms to authenticate the communication between DNS Servers to establish authenticity and integrity of DNS data. Participant will complete lab exercises based on number of scenarios.

Target audience

This course is designed for network engineers, systems administrators, and anyone who is involved in managing DNS operations.
