Comparative Study of Traditional vs Blockchain-Based Cybersecurity Approaches

With the expanding digital infrastructures and the rise of increasingly sophisticated cyber threats, there is a growing need for Cybersecurity. For many decades classic cybersecurity implementations (like firewalls, IDS, detection systems, centralized authentication protocols) have formed the foundation for digital defense. But these ways have limitations such as single points of failure, poor transparency and susceptibility to advanced persistence threats. Due to these challenges, blockchain technology has evolved as a suitable solution because of its characteristics of decentralized, immutable, and transparent architecture. In this paper, we compare traditional cybersecurity approach with blockchain-based cybersecurity approach by discussing strengths, weaknesses and areas of use of each approach. Evaluation of parameters — Data integrity, Scalability, Access control, Detection of threats, Anti-fragility against attacks, Among these key parameters, the advantages of both paradigms are emphasized as a trade-off between each other. The paper investigates the impact of blockchain on trust, auditability, and distributed defence in the context of case studies and recent advancements in mainstream application fields such as finance, healthcare, and IoT networks. Results show that though foundational security will always depend on classical ideas, combat systems based on blockchain will bring higher resilience and most notably, trust, in cyber-war setting. Our comparative analysis can help researchers and practitioners who look for hybrid or blockchain-augmented cybersecurity solutions in the transforming digital world.
