DNS Security Training

Duration: 2 days.

La formation est aussi disponible en français.

Other courses: Basic DNS, Advanced DNS, DNS and IPv6, DNS and Telephony (VoIP), DNS and RPZ, DNS on Windows Servers, LDAP Courses, Telecommunications/SS7 courses.

The primary focus of the course is BIND which is available on Linux, UNIX and Windows platforms. The course is offered with Linux (Fedora Core), FreeBSD or Windows 7, 8 or 10 as the platform for all exercises.

Summary

Reliable, robust and secure operation of the DNS hierarchy - from the root servers to an individual domain name server - is critical to all Internet operations. The course concentrates on the use of DNSSEC for the control of Zone Transfers, DDNS and zone Integrity and especially the automation of key-rollover using established tools. While the primary focus of the course is BIND other DNS software will be discussed.

Description

Students will review the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. DNS (DNSSEC) security is based on modern cryptographic techniques and processes. The student will learn the underlying principles without requiring mathematical knowledge. Specific implementation of shared-secret (symmetric) and public-key (asymmetric) implementations will be detailed covering Zone Transfer, Dynamic DNS (DDNS) and Zone Integrity. Secure DDNS integration with DHCP is covered and procedures and requirements for key management and key-rollover are illustrated. The course includes a number of hands on configuration exercises.

Audience:

The course is designed for DNS administrators, Network and System Administrators, Security specialists and those who need a thorough understanding of DNS security. Students should have taken the Basic DNS Course or have over 2 years exposure to DNS operations.
