A white paper issued by Cisco, “Preparing for DNSSEC: Best Practices, Recommendations, and Tips for Successful Implementation,” reviews best practices for implementing DNSSEC in a network infrastructure and includes configurations for Cisco software, platforms and devices. The step-by-step instructions, aimed at Cisco-using network administrators, also include insights from internal testing performed by Cisco Security Research & Operations, such as how different versions of Cisco products will affect validation. Authors John Stuppi  and Joseph Karpenko are members of the Applied Intelligence team in Cisco’s Security Research & Operations organization.
