Hitting the Cyber Security and Tech Industry headlines for 2021 has been the term “Zero-Day Exploits”. But what is it exactly?

Zero-Day vulnerabilities are very difficult to detect, as essentially the vulnerability has just been detected. That is, it has zero days of history and is usually unknown to those who wish to mitigate the vulnerability. The Zero-Day Exploit then is when a malicious actor takes advantage of this vulnerability to commit a cyberattack on the system.

So, what does this mean for you and me? It means we need to take a multi-layered defense approach to protect our IT systems. This is something that is hammered home to all IT Security personnel and is an ongoing effort from all Users. Keeping software and operating systems up to date, regular firewall reviews, and User education are the most common and first steps to ensuring a system’s security. Adding to this, an EDR (Endpoint Detection and Response) program can help monitor and mitigate unwanted programs and behavior. Regular vulnerability scans help an IT team identify weak points in software and operating systems and enable them with the means to mitigate those weaknesses.

All these defenses, when working in concert, lessen the digital ‘cracks’ in your infrastructure thus making it much more difficult for a malicious actor to target and break into your systems. No solution is perfect, but we can deter an attack and minimize the damage from that attack.
