What is Web Security Scanning?

Web Security Scanning is a process that automatically identifies and prioritizes security
vulnerabilities in web applications and websites.

How Web Security Scanning Works

Web security scanners use a variety of techniques to identify vulnerabilities, including:

Vulnerability scanning: This involves scanning the web application for known vulnerabilities, such as cross-site scripting (XSS), SQL injection, and cross-site request forgery (CSRF).
Fuzz testing: This involves sending random or unexpected data to the web application to try to trigger unexpected behavior or crashes. This can help to identify vulnerabilities that may not be detected by other scanning methods.
Denial-of-service (DoS) testing: This involves sending a large volume of traffic to the web application to try to overwhelm it and make it unavailable. This can help to identify vulnerabilities that may allow attackers to take down the application.
Reverse engineering: This involves analyzing the source code of the web application to identify vulnerabilities that may not be apparent from the surface. This is a more complex and time-consuming technique, but it can be more effective at identifying critical vulnerabilities.

Benefits of Web Security Scanning

Web security scanning can provide a number of benefits to organizations, including:

Early detection of vulnerabilities: Web security scanning can help to identify vulnerabilities early in the development lifecycle, before they can be exploited by malicious actors.
Reduced risk of data breaches: By identifying and remediating vulnerabilities, organizations can reduce the risk of data breaches and other security incidents.
Improved compliance: Many industries have specific regulations that require organizations to conduct web security scanning on their websites.
Peace of mind: Web security scanning can help organizations to sleep better at night knowing that their websites are protected from the latest threats.

Types of Web Security Scanning

There are two main types of web security scanning:

Automated scanning: This involves using automated tools to scan the web application for vulnerabilities. This is the most common type of web security scanning and is often done on a regular basis.

Manual scanning: This involves manually reviewing the web application for vulnerabilities. This type of scanning is more expensive and time-consuming, but it can be more effective at identifying complex vulnerabilities.

Web Security Scanning Tools

There are a number of web security scanning tools available on the market, ranging from free to premium. Some popular tools include:

ImmuniWeb Neuron
Acunetix
Qualys
Burp Suite
Nikto
OpenVAS

Frequency of Web Security Scanning

The frequency of web security scanning depends on the organization's risk profile and the sensitivity of its data. However, it is generally recommended that organizations conduct web security scanning at least quarterly.

Conclusion

Web Security Scanning is an essential tool for organizations that want to protect their websites from cyberattacks. By conducting regular web security scanning, organizations can identify and address vulnerabilities before they can be exploited, reducing the risk of data breaches and other security incidents.
