The U.S. Cybersecurity and Infrastructure Security Agency (CISA) announced the retirement of 10 Emergency Directives (EDs) issued between 2019 and 2024. The list includes critical infrastructure mitigations such as ED 19-01 (Mitigate DNS Infrastructure Tampering) and ED 20-03 (Mitigate Windows DNS Server).
This move signifies that mitigation strategies for these previously ’emergency’ threats have been integrated into standard operational procedures across federal agencies. This development carries significant implications for the Web3 ecosystem.
While the primary focus of Web3 security often lies in auditing smart contracts and protocols, the underlying conventional infrastructure—nodes, API gateways, development environments, and their dependency on DNS and OS layers—remains susceptible to the exact vulnerabilities CISA addressed. Domain hijacking or successful exploitation of OS-level flaws can often serve as an indirect access vector into DeFi platforms or centralized components of decentralized applications.
Web3 security professionals must ensure that their Operational Security (OpSec) incorporates traditional cybersecurity best practices, including diligent patching and rigorous infrastructure monitoring, alongside innovative protocol defenses. True Web3 security maturity means securing both the smart contract layer and the foundational infrastructure it relies upon.
