Zero-day
Explanation:
In the world of computers and technology, zero-day is considered as an error in the software or hardware which might be difficult to analyze. The zero-day vulnerability, if not detected on time, will allow hackers to exploit any kind of data from the computers being mitigated.
One of the possible solutions for fixing zero-day vulnerability is by using updates. Whenever a new form of zero-day attack is understood, an update is made in the existing software to prevent that type of zero attacks being made.
