Foundational Security

Definition ∞ Foundational security refers to the basic, fundamental security measures and principles upon which more complex security systems are built. It involves establishing robust access controls, secure coding practices, and rigorous data protection mechanisms as the bedrock of any digital asset or system. Ensuring these core elements are sound is paramount before implementing advanced security protocols.
Context ∞ Discussions regarding foundational security in the crypto space frequently address the hardening of core blockchain protocols against known attack vectors and the establishment of standardized security audits for new projects. The resilience of the underlying infrastructure against sophisticated threats remains a persistent area of focus for developers and regulators.
