This creates a reliable audit trail, facilitating rapid incident response and forensic investigations.<\/li>\n\n\n\n<li><strong>Decentralized Identity Management:<\/strong> Blockchain enables self-sovereign identities (SSIs), allowing users to control their own digital identities without relying on centralized authorities, which are vulnerable to attack.<\/li>\n\n\n\n<li><strong>Automated Access Control:<\/strong> Smart contracts, self-executing contracts with embedded access control policies, can be deployed on blockchain platforms.
