Definition ∞ IP Security, commonly known as IPSec, is a suite of protocols that provides cryptographic protection for Internet Protocol communications. It ensures data confidentiality, integrity, and authenticity across IP networks by encrypting and authenticating each IP packet. IPSec is frequently used to establish Virtual Private Networks (VPNs) and secure remote access, forming a foundational element of secure network infrastructure. While not directly blockchain-native, its principles of secure communication are relevant to the broader digital asset ecosystem.
Context ∞ While blockchain networks inherently offer cryptographic security for on-chain transactions, IPSec remains vital for securing the underlying internet infrastructure that supports digital asset operations. Exchanges, custodians, and users rely on secure network connections to access and manage their digital holdings. The discussion around IPSec in the crypto context often relates to the broader cybersecurity posture of platforms and the secure transmission of off-chain data.
