0-Day Vulnerabilities: What They Are and Why They’re Critical


Security for Everyone


Simply put, these are security flaws that have not been publicly disclosed.

That means that hackers who know about these vulnerabilities can exploit them before anyone has a chance to fix them. As nobody is aware of the vulnerability, there has yet to be created a patch for it.

It's known that big players in the game uses 0-days to attack nuclear power plants, government organizations, banks and other big companies. Some 0-days vulnerabilities on browsers (chrome, safari, edge), remote management services (RDP, telnet, ssh, etc..) or well-known content management apps (Wordpress, Joomla, etc..) are worth thousands and even millions of dollars, depending on the complexity and number of users impacted.

As a website owner, it is essential to understand the implications of 0-day vulnerabilities and have measures in place to protect your organization. Without proper protection and detection in place, this could leave your organization vulnerable to malicious attacks and data breaches.

Actually, there are only a few things you can do if you are SMBs (even enterprise companies and governments can not do much for 0-days vulnerability). The best way to protect yourself is to keep up with cybersecurity information and know when new vulnerabilities are discovered. That is why having a continuous security scanner is great solutions. If you have one, whenever any 0-days are published an automated system will check without requiring any manual operation and alert you if it is a risk for your organization.

Also it is important to maintain good activity visibility in order to be able to see what’s happening on the network, servers and application in real time and detect malicious activity as soon as possible.

Additionally, having a patch management process can help you roll out security patches quickly and efficiently so that your protection stays up to date.

So as you see, 0-day vulnerabilities are very critical because there is not much you can do to protect against them. However, having continuous security scanner, monitoring activities and a patching system quickly can mitigate the risk against 0-days vulnerabilities.
