Security Incident

Definition ∞ A security incident is an event that compromises the confidentiality, integrity, or availability of digital assets, systems, or data. In the cryptocurrency context, this can include unauthorized access to wallets, exploitation of smart contract vulnerabilities, phishing attacks, or exchange hacks. The analysis and response to such incidents are critical for understanding the security posture of blockchain networks and decentralized applications, and for preventing future occurrences. Prompt and effective management of security incidents is paramount for maintaining user trust and asset safety.
Context ∞ Security incidents are a constant source of news within the cryptocurrency domain, often detailing substantial financial losses or disruptions to services. Reports typically focus on the nature of the attack, the affected protocols or platforms, and the estimated value of stolen assets. The aftermath of these incidents often prompts discussions about enhanced security measures, forensic investigations, and the development of better incident response protocols.
