Zero Day Vulnerability Definition: Zero Day Vulnerability refers to a security flaw in software or hardware that is unknown to the vendor or has no vendor-provided patch available, leaving systems at risk of exploitation by attackers.
A zero-day vulnerability is a flaw in software or hardware that is unknown to the vendor or developer and for which no fix or patch yet exists. Because there is no available defense, attackers can leverage it through a zero-day exploit to compromise systems before the vendor becomes aware of and remediates the flaw.
Zero Day Vulnerability is one of the topics you'll master in the Security+ Boot Camp.
