TL;DR: As we move towards a more decentralized web, new and complex security challenges arise. The open-source nature of Web3 means that code vulnerabilities are common and can spread quickly. To address these challenges, we need to prioritize trust and security. We can do this by scanning for Smart Contract vulnerabilities, strengthening IAM for cloud environments, providing visibility into web3 applications, utilizing AI/ML techniques, and regularly auditing and monitoring the system. By continuously testing and monitoring the system, we can stay ahead of potential threats and ensure a secure and reliable digital landscape.
