Learn All About Web Application Security Testing: Methodology, Tools, & Checklist

Web Application Security Testing or simply Security Testing is a process of assessing your web application for security flaws, vulnerabilities, and loopholes in order to prevent cyber attacks, data breach, and data loss. A meticulous security testing reveals all hidden vulnerable points in your application that runs the risk of getting exploited by a hacker.

In the last decade, web applications advanced with unprecedented speed to enter finance, banking, e-commerce, and every other industry you can think of. For the smart cybercriminals, this seemed like a perfect opportunity and consequently, cybercrimes leapt up. The hastily coded & unsecured applications succumbed to cybercrimes and businesses closed with the drop of a hat. This is why web application security testing holds supreme importance in web app development in today’s scenario.

In this guide, we answer the most asked questions on web application testing, starting off with why you should get one.

Why mustn’t you neglect web app security testing?

Digitization bestowed us with many boons and new banes — Hackers & Cyber threats. With every passing day, hackers are developing more and more sophisticated techniques to bypass the previous security standard you have established. A regular web application security testing keeps you updated with your application’s security and vulnerabilities that may be used against your app.

For the longest time, developers’ complete focus was converged on building apps and software without giving a second thought to its security. Cybersecurity was being brushed under the carpet at boardroom discussions and business planning meetings. This changed when security breaches in business giants started making headlines and companies started losing millions. This is when cyber threats were acknowledged and cybersecurity was given due importance and priority.

Hence, you must not overlook web application security testing if you want to:

1. Identify flaws and vulnerabilities in your application:

The most important benefit you can get out of a thorough security testing is that it uncovers all security flaws and vulnerabilities in your application. Web app security testing has emerged as a crucial step in the app development cycle (SLDC), making developers mindful of security while they build the application.

2. Comply with laws:

To regulate data security & privacy in web applications, councils and conglomerates were formed and laws were implemented. Web application security testing was mandated for many businesses (such as e-commerce, finance, banking etc) to protect the user interests.

It is very important for a business owner to conduct a web application security testing for their application and that too regularly in order to comply with the current laws, if you’re into a serious business. Web app security testing is not limited to just businesses, but is equally crucial for developers also, who push out web apps for public use on app distributor platforms or as a SaaS (Software as a Service).

3. Analyze your current security:


A web app security testing also checks your current security measures and detects loopholes in your system such as a firewall, configurations among several other security measures.

4. Detect security breaches and anomalous behavior:

Another huge benefit of conducting a Security audit is that it helps you identify security breach or hacker-behavior in your application. As per IBM, on average, it takes companies 192 days to identify a data breach in its system. By this time, the damage may become irrevocable. A security testing sniffs out hacks and breaches in due time saving your business from adverse consequences.

5. Formulate an effective security plan:

Detailed outcomes of an audit can help you plan and prioritize risk responses better against a breach or a hack. It also helps you formulate an incident response mechanism as per your app’s or business’ needs.

Getting started with web app security testing

You can either hire a security professional to audit your application or have an in-house team to perform security testing for you regularly. If you’re a solopreneur or an app developer, you can perform a preliminary web application security testing on your own as well. 

Note: Owing to the complex nature of security testing, there are too many ways one can flater. Hence, it is advised that you go with a professional security testing for best results and better protection of your app and its users.

That said, you sure can perform a preliminary web app security testing (minus the code analysis) yourself. Follow these steps for the same:

  1. Asset discovery: Identify your application’s security areas and its complementary assets that would be included in the testing.
  2. Check for outdated versions: Verify if your application is up to date. Repeat with other assets.
  3. Check permissions: Check if your app follows secure rules for user permission and roles.
  4. Check security protocols: Check if there are security measures such as a firewall, malware scanner, SSL, etc are in place.
  5. Analyze code rigidity with penetration test: Analyze your code for CVE, code injection, SQLi, and other common attacks. (This would require more hands-on experience with security testing.)
  6. Test database security: Check if your database is hardened against malicious SQL queries or not.
  7. Run configuration tests: Check your application as well as your network’s configurations structure and if they are secure. 
  8. Check network assets: Test your router, switches, printers, servers, desktops, etc against known CVEs and specially crafted attacks.
