Top 10 Open Source Security Testing Tools for Web Applications

The Internet has grown, but so have hacking activities. Every now and then there is some news regarding a website being hacked or a data breach. Technology has come a long way, but so does hacking. Just like the digital world, hacking techniques and tools have also become more sophisticated and also threatening.

Better late than sorry! It’s important to keep your website or web applications foolproof against malicious activities. What you need to do is to use some security testing tools to identify and measure the extent of security issues with your web application(s).

The primary function of security testing is to perform functional testing of a web application under observance and find as many security issues as possible that could potentially lead to hacking. All of this is done without the need to access the source code.

Before delving into some of the best open-source security testing tools to test your web application, let’s first acquaint ourselves with definition, intent, and need for security testing.

Security Testing

The Definition – In order to assure that data within some information system stays secure and not accessible by unapproved users, we use security testing. Successful security testing protects web applications against severe malware and other malicious threats that might lead it to crash or give out unexpected behavior.

Security testing helps in figuring out various loopholes and flaws of a web application in the initial stage. Furthermore, it also helps in testing whether an application has successfully encoded security code or not. Primary areas covered by security testing are:

  • Authentication
  • Authorization
  • Availability
  • Confidentiality
  • Integrity
  • Non-repudiation

The Intent – Security testing is used by organizations and professionals throughout the world to ensure their web applications and information systems remain secure. Chief purposes of deploying security testing are:

  • To help improve the security and shelf-life of a product
  • To identify as well as fix various security issues in the initial stage of development
  • To rate the stability in the present state

The Need – Why do we need security testing? Well, there are a number of reasons, ranging from analyzing the degree of security to the prevention of unexpected breakdowns in the future. Some of the most important reasons are:

  • Avert inconsistent performance
  • Avoid losing customer trust
  • Avoid losing important information in the form of security leaks
  • Prevent information theft by unidentified users
  • Save from unexpected breakdown
  • Save additional costs required for fixing security issues

There are several free, paid, and open source tools available to check the vulnerabilities and flaws in your web applications. The best thing about open source tools, besides being free, is that you can customize them to match your specific requirements.

Which tool is better in security testing: ZAP or Burp Suite?

Edwin Soto
Edwin Soto

ZAP and Burp Suite has their own features and used for specific purposes. ZAP has an inbuilt browser setup that would spider the target server so this need not to be proxy configured your web browser. Whereas the Burp Suite needs to be configured as a proxy to work between your browser and the target server.

How are API security testing tools are different than website security testing?

Evelyn Baldwin
Evelyn Baldwin

API security testing is use to ensure that API is safe. It requires a software program to send calls to API, then get output and fetch the system’s response. If there is any error in API it affects all the applications that rely on that API. Some free tools for API testing are Fiddler, Wireshark etc.
Whereas a website security testing is the process to find the confidential data in a website is safe or not. In website security testing we check that a user can perform only those tasks for which they are authorizes to perform. Some website security testing tools are Wapiti, Vega etc.

What is port scanning?

Alton Walton
Alton Walton

Port scanning is the act of knocking various doors to check that which one is locked. In the technical language, this is the process we identify open ports and services available on a network host. These applications can be used by attackers to find network services running on a host or by administrators to verify security policies. Sometimes it is also used by hackers to target victims in order to locate holes within the specific computer.

How to test the security of cloud application?

Meghan Walters
Meghan Walters

This is the new type of testing in which cloud applications are tested by tools, scanner or solution hosted in cloud. It is different because traditional testing requires on-premises tools. Cloud based testing provides cost effective choice when goals are similar. As many applications are deployed in cloud, a focus shift from securing applications to securing applications fast, at scale.

What is the primary purpose of a vulnerability scanner?

Toby Parks
Toby Parks

Vulnerability scanning is the process, which detects and classifies the computer’s weakness and predicts the effectiveness of discovered points. A vulnerability scanner is a program which is designed to assess networks, computers, and applications etc.to finds their weaknesses. In simple words, the vulnerability scanner used to discover the weakness of the system to be tested.

How do you conduct a vulnerability assessment?

Colin Leonard
Colin Leonard

Vulnerability assessment can be done in 4 steps easily.
1) Initial assessment to identify the assets and define the risk. It’s important to find the device risk tolerance level that the device you will test.
2) System baseline definition to gather the information about system before Vulnerability assessment. At least you should know if the device has open ports, services and processes that should not be opened.
3) Perform the vulnerability scan- Use the related tools and scanner to get the best results on Vulnerability assessment platform. Here, this is important to find the client industry context and determine that scan will be performed at once or segmentation is required.
4) Vulnerability assessment report creation- To get real value from the final report, pay attention to the extra details in report.

What is VAPT?

Joan Sparks
Joan Sparks

VAPT stands for Vulnerability Assessment and Penetration Testing which is 2 types of vulnerability testing. It performs 2 types of tasks with the different results within the same area of focus. Vulnerability assessment tools discover the vulnerability but they do not differentiate the flaws that can be cause to damage or those that can’t, while penetration testing find exploitable flaws and measure the severity of their. A vulnerability test can be done without pen test but you can’t have pen test without vulnerability test.

What is SAST and DAST?

Carole Mendez
Carole Mendez

SAST- SAST stands for Static Application Security Testing. This is a white box testing method which tests the application from inside out by examining the source code in such conditions that indicates security vulnerability might be present in the system. SAST scanners need to support the language used as well as web application framework being used.
DAST- DAST stands for Dynamic Application Security Testing. DAST is black box testing technique. In which an application is tested from the outside in by examining an application in the running state and applying an attack just like an attacker would.

What is Software Security Testing?

Marcia Dixon
Marcia Dixon

Software Security testing is a testing technique of the software intends to reveal the flaws in the information system and determine that the data and resources of the software system are protected from possible intruders. Security testing has its own limitation that means if the system passes through security testing it doesn’t mean that no flaws exist in the system or the system adequately satisfy all security requirements.

What is a security pen test?

Theodore Copeland
Theodore Copeland

Pen test is the abbreviation used for penetration testing is the simulated cyberattack on your computer system to check and evaluate the security of your system. The test result will identify the both weakness (or we can say vulnerabilities), potential to gaining and maintaining access to data, as well as strength of the system by enabling a full risk assessment to be completed.
