Blockchain in cybersecurity: opportunities and challenges 

The document outlines how blockchain’s core properties—immutability, transparency, decentralization, and automation—can bolster cybersecurity by improving audits and compliance, enabling automated incident response through smart contracts, increasing resilience against DDoS, supporting zero-trust access control, and enhancing secure, distributed file storage. It is an informational overview advocating blockchain as a complementary security technology rather than detailing any specific incident or threat intelligence.
