What is Web Application Security Testing?
Web application security testing is the process of finding security vulnerabilities in source codes of web apps, using manual and automated application security testing methods and multiple tests.
In other words, security of a web application is all about securing a web application code from cyber attacks that leave no stone unturned to exploit application code vulnerabilities.
13 Application Vulnerability Scanners
1. Zed Attack Proxy (ZAP)
The Zed Attack Proxy (ZAP) is an open source web application security tool. It has been created by the organization OWASP (Open Web Application Security Project)and helps find application vulnerabilities or flaws.
OWASP ZAP Zed Attack Proxy is both automated and manual web application security testing tool and is available for Windows, Unix/Linux and Macintosh platforms environment.
A beloved tool for both penetration testers and security researchers, OWASP ZAP Zed Attack Proxy is easy to use, affordable and has tester-built community support. As part of aggressive innovation roadmap, it’s frequently updated with new features, bug fix releases when needed, through community contributions.
Wfuzz is a command line tool written in Python for Linux to assist security researchers in finding and uncover potential vulnerabilities within a target application.
Fuzzing is an activity performed by software testers and security professionals who wish to determine vulnerabilities within a particular application.

Why is Web Application Security Testing Important?
The importance of a secure web application architecture becomes more evident with reports like 2018 Verizon Data Breach Report .
Even in 2021, the Verizon Breach Investigations Report 2021
- With more than 90%, web applications, as attack vectors, are still the favourite target of cyber attackers.
- Involvement of web applications in more than half of cyber incidents has been observed. This includes servers in the form of web apps. Email and Databases etc.)
- Pattern of cyber attacks on web applications has touched a new realm of heights and is on its highest level since 2016.
- Patching application vulnerabilities is still a ‘task’ for many. Surprisingly, once found, it takes more than 70 days to patch a vulnerability and approximately 40% of cases are like this.
- Hacking was the prime reason for attacks in the form of system intrusion.
- Cent per cent web application security cyber attacks happen from the outside and more than 85% of such attacks revolve around money as motivation.

What are the types of Application Security Testing?
There are 4 types of web application security testing
What is Dynamic Application Security Testing (DAST)?
Dynamic Application Security Testing (DAST) is a type of security testing that examines an application while it is running. It simulates an attack by sending input to the application in an attempt to exploit vulnerabilities. DAST tools can identify issues such as SQL injection, cross-site scripting (XSS), and broken authentication and authorization. The main benefit of DAST program is that it can identify vulnerabilities that may not be apparent during static analysis.
What is Static Application Security Testing (SAST)?
Static Application Security Testing (SAST) is a type of security testing that examines an application’s source code or binaries without executing the application. It analyzes the application’s structure and looks for patterns that indicate vulnerabilities. SAST can identify issues such as buffer overflows, unvalidated inputs, and insecure storage. The main benefit of SAST is that it can be used early in the development process, allowing vulnerabilities to be identified and fixed before the application is deployed.
What is Runtime Application Self Protection (RASP)?
Runtime Application Self Protection (RASP) is a security technology that is designed to protect an application from attacks while it is running. It is typically implemented as an agent that runs alongside the application and monitors its execution for any signs of an attack.
RASP can identify and block attacks such as SQL injection, cross-site scripting (XSS), and broken authentication and authorization. The main benefit of RASP is that it can protect an application in real-time, without requiring any changes to the application’s source code.
What is Penetration Test?
A Penetration Test (Pen Test) is a type of security testing that simulates a real-world attack on an application or network. It is intended to identify vulnerabilities in the system that could be exploited by a malicious attacker. A penetration tester will use a combination of automated tools and manual techniques to attempt to gain unauthorized access to the system. The main benefit of a Pen Test is that it provides a realistic assessment of an application’s security by simulating an attack from an actual attacker.
