Zero-Day Vulnerability: Defense Strategies

A zero-day is a weakness in hardware, software or firmware that is not known to the parties responsible for patching or fixing the flaw. The term zero refers to an attack that has zero days between the time the vulnerability is discovered and the first attack. Once a zero-day vulnerability is known to the public, it’s known as a one-day or n-day vulnerability.
