Effective Ways Of Stopping Zero-day Vulnerabilities

2nd May 2019 | By Administrator

An Introduction To Zero day Vulnerability

Stuxnet is a computer worm that affected the computers in Iran’s nuclear plant Natanz back in 2010. This malware exploited a zero day vulnerability in Windows at that time. It affected computers controlling the centrifuges of the nuclear plant. The worm’s attack was successful. The centrifuges were being controlled from a distant location. The attack made the centrifuges spin at a very fast rate.

Zero-Day Vulnerability

The attack continued for several months. This made the infected machines to wear down over time. The Iranian government had to remove most of these centrifuges during that time. This affected their nuclear capabilities. The incident shows the usage of technology as a cyber weapon.

You can prevent this scenario from happening to you. You need to know the effective ways of stopping a zero-day vulnerability. Before that, you must first learn what a zero-day vulnerability is. You also need to know the difference between a zero-day attack and a zero-day exploit.

You must also learn how to detect and prevent zero-day attacks and zero-day exploits. You will also understand why it is necessary to use SecureBox.

What Is A Zero-day Vulnerability?

A zero-day vulnerability refers to a programming error in the software that the vendor isn’t aware of. Cybercriminals exploit this flaw or bug to their advantage. The software developer will then create a patch after knowing the vulnerabilities. This patch contains the programming fix and other updates as well.

Here’s an example:

An attacker sees a zero-day vulnerability while exploring a new messaging application.

A zero-day attack targets and infects these vulnerable applications or programs. Cybercriminals have various ways of attacking and some are even automated.

Here’s a zero-day attack example:

The cybercriminal heard the newest vulnerability of a popular messaging application. They then decide to launch an attack on this application.

A zero-day exploit happens when someone takes advantage of a software vulnerability. The entire process of creating a fix will take some time. Cybercriminals exploit this timeframe to their advantage.

Here’s an example:

The attacker infects the software with malware. They do this while there is no available fix yet for the vulnerability.

You now know what a zero-day vulnerability is. You also understood the difference between a zero-day attack and a zero-day exploit. It’s now time to learn about zero-day attack prevention in the next section.

Different Ways Of Stopping A Zero-day Vulnerability

A zero-day vulnerability is stoppable. One way is to look for clues or pieces of evidence. Here are some effective zero-day exploit detection methods:

1. Detection through signature – malware and zero-day attacks leave traces of evidence. This is their digital “signature” in the system. You can detect zero-day exploits by analyzing known signatures from previous attacks. You can also analyze the statistical data of previous attacks.

2. Detection through behavior – you can look for attack patterns and variations of these.

3. Detection through combination – you can also mix and match the other methods to your liking.

These detection methods aren’t enough. We need to add more security solutions to our zero-day vulnerability problem.

We can reduce zero-day attacks by also doing the following:

● Perform vulnerability scanning on a regular basis. You should scan your network or system for vulnerabilities. You can do this by using SecureBox which has cloud-based vulnerability scanning features. SecureBox helps lessen the risk of a zero-day vulnerability from happening.

● Apply patches as soon as possible. A patch contains fixes and updates to applications. This also includes the fix to previous vulnerabilities. Updated software has a lesser chance of having a zero-day vulnerability. SecureBox can help you by providing you with the following reports:

1. Malware threat detection reports

2. Network IP change reports

3. Application upgrade reports

4. Remote control detection reports

5. Application usage reports

6. License usage reports

7. Injection detection reports

8. Application uninstall/install reports

9. Email notifications based on reports

● Use a web application firewall or WAF. This filters out web traffic to your network for any suspicious activity. SecureBox also watches over your network 24/7. A zero-day vulnerability will not likely to happen because of this. SecureBox is also an award-winning intrusion detection and prevention product. This means it’s tried and tested by many.

● Restrict network access. There should be a restriction on network access. The security principle of least privilege is applicable here. Normal users should have default ordinary privileges or access rights. There should be at least one administrator account per network. A zero-day vulnerability is avoidable if the attacker can’t get access to your network. SecureBox can add another layer of security by whitelisting certain programs. These whitelisted programs are the only ones who get access to network resources.

Conclusion

A zero-day vulnerability is a real-world cybersecurity risk. You can lessen this risk if you know how the different ways of stopping a zero-day vulnerability. Using SecureBox will counter most zero-day attacks. Sign up now for a free demo!
