#  Zero-Day Attack Prevention: Fix The Vulnerabilities In Your System Before It Gets Too Late! 

## **Zero-Day Attack Prevention: Fix The Vulnerabilities In Your System Before It Gets Too Late!**

### What Is Zero-Day Attacks?

A [Zero-day attack](/content/zero-day-attacks/) is a _cyber-attack whose main objective is to target a “zero-day” software vulnerability that is unknown to the user or the developer_. These vulnerabilities are termed as “zero-day” (also maintained by ‘CVE’ list) because developers have **zero days to fix it** or to come up with a patch. Cyber adversaries exploit such vulnerabilities easily because no security measures, firewalls, or defenses exist at the moment of discovery to counter the new threats and protect the system. A few famous [zero-day attack examples](/content/zero-day-attacks/zero-day-attack-examples/) are Stuxnet, Windows zero-day attacks, Sony zero-day attacks, and Operation Aurora. One of the most recent zero-day attacks in 2019 was CVE-2019-1132\. _These attacks call for the urgent need for improved zero-day attack prevention methods and solutions_.

### Effective Zero-Day Attack Prevention Techniques

Zero-day exploits are initially unknown, and so _there are usually no security measures or patches available to counter them_. Organizations can take some protective control measures against these unknown vulnerabilities, such as:

#### Penetration Testing

_Discovering an attack is crucial_. So how are zero day attacks discovered? Software vendors provide **vulnerability scanning solutions** in which [simulated attacks](https://www.softwaretestinghelp.com/vulnerability-assessment-tools/) are carried out on the software code. These solutions conduct code reviews and search for new vulnerabilities that may have arisen after software updates or are still unknown.

#### Security Patch Update

Another measure to prevent zero-day exploits is to keep **security patches up to date**. A software vendor needs to test and update patches as soon as a new vulnerability is discovered. New vulnerabilities also appear with the latest updates, although old ones are patched and hence must be tested before deployed into the production environment. _Regularly updating your software can keep you protected from many known and unknown cyber-risks_.

#### WAF And RASP

The WAF (Web Application Firewall) is one of the most competent methods for achieving [zero-day protection](/content/zero-day-attacks/zero-day-protection/) as its deployment on the network edges helps in reviewing incoming traffic and **filtering out malicious data** packets that might exploit system security vulnerabilities.

RASP (Runtime Application Self Protection) is one of the latest advancements in the field of zero-day attack prevention. In it, an application works under the supervision of agents that examine the **payload requests** taking into consideration the application code at runtime. This method results in the accurate determination of whether a particular request is normal or malicious so that the software can counter the threat accordingly.

### Final Words On Zero-Day Attack Prevention

_A zero-day attack is one of the most relentless threats to organizational information security_. A cyberattack such as [Windows zero-day](/content/zero-day-attacks/windows-zero-day/) attacks can compromise several **million computers at once.** By implementing the control measures explained above, and employing zero-day attack prevention techniques such as penetration testing, regular software updates, and using WAF and RASP, one can mitigate the risks from zero-day exploits to a great extent.
