Securing Distributed Applications

Distributed applications (DApps) represent a foundational shift in executing computational tasks and services across networked environments. By distributing processes and data across multiple nodes, these applications achieve scalability, redundancy, and fault tolerance, making them essential to sectors such as finance and energy. However, this decentralized architecture introduces complex cybersecurity challenges, including expanded attack surfaces, inconsistent data integrity, and unique incident response requirements. This video explores the structure and vulnerabilities inherent in DApps, emphasizing smart contracts, secure communication protocols, and integration with blockchain-based infrastructure. It presents a review of mitigation strategies including applying NIST frameworks, zero trust architecture, and using technologies such as IPFS and ephemeral certificates. ====== Table of Contents: 00:00 - Introduction 01:50 - DApp Definition and Application 03:28 - DApp Vulnerabilities and Challenges 03:46 - Attack Surface Expansion 06:17 - Data Consistency and Integrity 07:46 - Authentication and Authorization 09:55 - Incident Response Complexity 12:22 - Mitigation Strategies 12:42 - Implementation of Security Frameworks 13:40 - Secure Communication Protocols 15:47 - Regular Security Assessments 17:39 - Incident Response Planning 19:57 - Zero Trust Architecture 22:20 - IPFS and Ephemeral Certificates ===== Research paper on which video is based https://www.researchgate.net/publicat...
