The Cybersecurity and Infrastructure Security Agency (CISA) is proud to offer the Incident Response Training event, Preventing DNS Infrastructure Tampering Cyber Range Training (IR206) on Tuesday, August 13, 2024. The 200-level training events are open to government employees and contractors across federal, state, local, tribal, and territorial government, educational partners, and critical infrastructure partners. Please use your organization email address when registering. 

 This course is ideal for those working in cybersecurity roles who are interested in learning technical incident response skills and requires active engagement from all participants. The course assumes a mixed audience (e.g., from disparate teams and organizations) of mixed capability. 

 DNS is one of the core foundations of the internet however, it continues to be one of the mechanisms attackers use to perform malicious activities across the globe. In this course participants will learn about various concepts associated with DNS, become familiar with DNS tools and mapping information, get introduced to common DNS tampering techniques, and gain an understanding of DNS mitigation strategies to enhance security. 

 Experience these benefits and more: 

  • Practice in a realistic environment: Analyze network and host-based artifacts and implement remediation changes for the identified vulnerabilities.  
  • Learn how to implement remediations: Course exercises include remediating vulnerabilities. 
  • Identify and mitigate vulnerabilities in real time: Students will identify DNS infrastructure tampering techniques and mitigate them. 
  • Expert facilitation and peer discussion: Throughout the course, expert cybersecurity engineers will moderate discussion and conduct a recovery debrief for the exercises. Participants are also encouraged to help one another and offer relevant input to address peers' questions.

This exercise is a step-by-step, facilitated experience that uses a keyboard approach to understand these topics in a realistic technical environment. 

Approved registrants must attend a mandatory student technical check the day before the training to establish a connection to the course content and lab environment.
