Background The advent of quantum computing poses significant challenges to traditional cryptographic methods employed in securing network protocols. Methods This study evaluates the vulnerabilities of Transport Layer Security (TLS), Internet Protocol Security (IPsec), and Domain Name System Security Extensions (DNSSEC) under quantum threat scenarios. Leveraging the STRIDE and PASTA threat modeling frameworks, the research categorizes threats and simulates attack scenarios to provide a comparative analysis of these protocols. Results The findings reveal critical vulnerabilities, particularly in public-key cryptography, and highlight the urgency of transitioning to quantum- resistant cryptographic solutions. Conclusions The study proposes practical mitigation strategies to enhance the resilience of these protocols, contributing to the advancement of post-quantum cryptography and secure digital communications.
