Secure Node Management

Definition ∞ Secure node management refers to the practices and protocols implemented to protect the operational integrity and cryptographic keys of nodes participating in a blockchain network. This involves robust cybersecurity measures, regular software updates, physical security for hardware, and stringent access controls. Effective management ensures the node’s continuous operation, resistance to attacks, and proper execution of network functions. It is crucial for maintaining network decentralization and security.
Context ∞ News often covers advancements or vulnerabilities related to secure node management, particularly for proof-of-stake networks where nodes validate transactions and maintain consensus. Discussions might focus on new hardware security modules, best practices for preventing denial-of-service attacks, or the importance of decentralizing node operators. The security of individual nodes directly impacts the overall resilience and trustworthiness of the blockchain.
