Defining a Zero-Day Exploit

Explaining Zero-Day Exploits

Zero-day exploits are flaws within a system or application that go undiscovered until a threat actively targets it. Depending on the severity of the attack, it could then expose this vulnerability to the general public, or if the attack is more discrete, it could remain hidden, making the attack even more difficult to pinpoint. In any case, the definition of a zero-day exploit remains the same; it?s an undocumented flaw that becomes exploited by a security threat.

What Makes Zero-Day Exploits So Dangerous?

There is a big reason why there is so much trouble made out of these types of exploits, and it?s because they are undocumented and difficult to predict or anticipate. The unknown factor means that researchers and individuals don?t know that these threats exist, making them difficult to prepare for or remedy until it is too late.

When these types of threats are discovered, developers do all they can to remedy the problem before the threats cause too much damage, but it?s not always simple to fix them. Every moment that the flaw is not resolved is a moment when attackers could be leveraging the flaw?especially if it is out in the open.

What Should You Do About Them?

Since zero-day flaws are generally unknown to security researchers and professionals until they are actively being exploited, it is hard to take action with them until a fix has been issued. That said, you do a lot to protect your business from the majority of threats, even if there are issues with your security infrastructure.
