Operational Security

Definition ∞ Operational security, often abbreviated as OpSec, is a process that involves protecting sensitive information from adversaries. In the context of digital assets, it encompasses the practices and protocols individuals and organizations implement to safeguard private keys, prevent unauthorized access to wallets, and secure communication channels. Strong operational security is vital for preventing theft and maintaining the integrity of digital holdings.
Context ∞ The importance of operational security is frequently highlighted in news concerning digital asset theft and security breaches. Discussions revolve around best practices for key management, the use of hardware wallets, and the detection of social engineering attacks. Security experts continually emphasize the need for vigilance and robust procedures to mitigate the risks associated with managing digital assets, particularly as the threat landscape becomes more sophisticated.
