Computer hackerAlternatively referred to as zero-day exploit or 0-day, a zero-day flaw is any exploit in an operating system, software, or hardware that is exploited on the same day it is discovered. These flaws become known to the public when a malware program exploits the flaw and compromises the product, computer, or network connected to the computer. These exploits can cause serious issues and keep a system vulnerable until the company releases a fix.

Tip: To help protect against zero-day exploits use an intrusion detection system and set up network access control to prevent unauthorized access to your network.
