## Zero Day Vulnerability Management

Zero day vulnerability management is the process of identifying and remediating previously unknown security flaws that have not yet been patched by the developers. Because these vulnerabilities are unknown to the creators, they are highly dangerous and often targeted by sophisticated attackers.

Managing them requires a robust system for rapid incident response and the ability to deploy patches under extreme time pressure. Organizations often maintain specialized security teams to monitor for signs of zero-day activity and to act immediately upon discovery.

This involves constant threat intelligence, proactive monitoring of on-chain activity, and the ability to push emergency upgrades. It is a high-stakes discipline that tests the resilience and adaptability of a protocol.

The goal is to detect the exploit as early as possible, ideally before it is widely used, to minimize the impact on the protocol and its users.
