Defining a Zero-Day Exploit

Today, we discuss what exactly a zero-day exploit is and why it matters to your business’ cybersecurity efforts.

With so many threats out in the world, it’s no surprise that some of them target undiscovered vulnerabilities. These types of threats use what are called zero-day exploits to make attempts at your sensitive data and technology infrastructure. What is it about zero-day exploits that you must keep in mind during your day-to-day operations and in planning for the future?

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?

These exploits cause substantial concern due to their undocumented and unpredictable nature. Their unknown existence makes it hard for researchers and individuals to prepare for or address them until it’s 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?

Zero-day flaws remain unknown to security experts until exploited, making immediate action challenging without a fix. Despite potential security infrastructure issues, you can take substantial measures to protect your business from the majority of threats.
