Introduction
In today’s digital world, more and more vulnerabilities are appearing in organization’s systems. Zero-day vulnerabilities are one of them. Vulnerabilities in a system cause considerable damage as they make it easier for hackers to break into the systems and take confidential data or affect their operation. In this article, we will mention what is a zero-day vulnerability and show how to protect your company against its attacks.
What is a Zero-day vulnerability
Zero-day is called a vulnerability that has been discovered but has not been resolved yet. It is still unknown to security vendors so there is not a patch for it. Zero-day vulnerabilities are causing severe damage to businesses as cybercriminals exploit them in order to attack their systems. These exploits are called zero-day exploits. Unfortunately, zero day exploits usually succeed, because developers didn’t take the appropriate actions in time. Sometimes, vulnerabilities will not be detected for months or years, so companies should take the appropriate actions to discover them before hackers do.
How is a business able to avoid zero-day attacks? Let’s find out.
Ways to mitigate Zero-day attacks
Penetration Testing
First of all, the most vital measure you should take to protect against zero-day exploits is penetration testing. As we already analyzed in a previous article, penetration testing is a type of security assessment. Penetration testing is a simulation of an attack on systems using various procedures that cybercriminals may also use. Moreover, pentest attempts to test networks, applications, platforms, etc. with the aim of proving that vulnerabilities that appear are harmful risks to the systems. The goal of penetration testing is to check the effectiveness of the security of the company’s networks and systems with the purpose of ensuring the prevention of cyber-attacks.
Have an incident response plan
Every organization of any size and industry should implement an incident response plan to prepare for cyber-attacks. An incident response plan provides procedures in order to identify and face cyber-attacks. Using an incident response plan, you have a major advantage in being prepared to mitigate the risks of zero-day attacks too. Also, it helps companies to ensure their defense using instructions on how to prepare and learn to respond to threats. It is necessary for every business to become proactive to control the risks with proper actions as fast as possible.
Conclusion
In conclusion, zero-day vulnerability is especially important as it can cause a series of cyber-attacks without being noticed. In order to avoid exploiting zero-day vulnerabilities and keep systems secure, companies should implement the above preventive actions.
