Overview of Quantum Security Administration and Threats

This document is a guide focused on quantum security administration, detailing the threats posed by quantum computing to network and data security. It outlines the vulnerabilities of classical cryptographic methods, particularly public key infrastructure (PKI), to quantum attacks, specifically highlighting the potential for Harvest Now, Decrypt Later scenarios. The guide emphasizes the importance of transitioning to quantum-resistant technologies, such as those defined in RFC 8784, RFC 9242, and RFC 9370, which provide mechanisms for creating secure IKEv2 VPNs. These standards facilitate the implementation of hybrid key exchange methods that combine classical and post-quantum cryptographic techniques to enhance security. The document also discusses the characteristics of quantum computers and their ability to process data at unprecedented speeds, which could render traditional encryption methods obsolete. Additionally, it provides guidance on best practices for preparing for post-quantum migration and securing data against future quantum threats.
