web application penetration testing
Websites are usually client server applications which require testing to ensure that it brings complete satisfaction to the clients when they are using a particular web application. While testing a particular web application certain things are to be kept in mind which are as follows:
- Functionality Testing: While testing for the functionality of the web application certain points are to be kept in mind. First of all you need to validate your HTML or CSS. Next you need to check the forms and their workability in the various pages of the web application along with the various cookies. Next comes the various links that are present on the webpage or website that you have created. Last but not the least is the database testing which checks the consistency of the database along with integrity.
- Usability Testing: You have created your web application to be used by your customers so usability is an important part of the whole system which should be given special importance. Test the web application for easy navigation of the webpage so that smooth operation of the same is ensured. Next comes to the checking of the contents that make up the web page. It should be simple and easily understandable. Search option, sitemap, help files etc. should be present on the web application to help the users.
- Interface Testing: While testing the interface you need to pay special heed to the interface between web server and application server and the interface between the application server and database server. You need to check the various interactions between these two interfaces as well as how the various errors are handled by them. Check for the various error messages if any and also what happens when the communications are stopped midways. Also you need to check that the error queries are properly generated by them.
- Compatibility Testing: The compatibility testing for the web application includes checking for the compatibility of browsers, operating systems, compatibility with the mobile devices as well as the printing options available on the web application which should be customizable. Make sure that your web application is compatible with all the major browsers and operating systems to provide your users with freedom of choice. Also as more people are accessing the web on the mobile devices, you application should be easily accessible or browsed through the same.
- Performance Testing: You never know what kind of traffic inflow you will have on your web application at any given day which makes performance testing very important for your web application. Stress test your application in order to make sure that your web application wouldn’t snap under excessive pressure and would return to its normal working condition even if it did snap. Load testing of the application is also important to make sure that the web application is capable of handling excessive load if required.
- Security Testing: Your customers will be trusting you when they provide you with their personal details while they are using your web application and you have to make sure that these details are safe with you and would not be leaked. For this you need to make your web application is not prone to or can’t be easily hacked. Also check the CAPTCHA if you are applying any along with the SSL which is use as security measures and logging of all the error messages.
This is a complete all important check list for web application testing which will ensure that your web application runs smoothly and provides customers with complete satisfaction.
A large percentage of people nowadays access websites and web applications on their smartphones, tablets and phablets. Also, Google uses mobile-friendliness as a key metric to rank websites. That is why, a gradual increase is being noted in the enterprises opting for responsive design to make their web applications deliver quality user experience across a wide variety of devices. However, it is also important for businesses to get the functionality, performance and user experience of the websites tested thoroughly to impress and engage website visitors. The businesses can always effectuate web application testing by following a number of best practices.
5 Web Application Testing Best Practices Each Tester Must Know
1) Test Web Services Independently
2) Perform Elaborate Cross-Browser Compatibility Testing
To deliver quality user experience, the web application must run seamlessly on different types and versions of web browsers. But the older versions of certain browsers do not support HTML5 and CSS3. So the testers need to ensure that the app runs smoothly on different versions of each commonly used web browser. However, they cannot assess the cross-browser compatibility of the website without using specialized tools. The business must pick the right automation tools to help testers check the application’s functionality across various browsers quickly and efficiently.
3) Pick Specific Criterions for Usability Testing
The usability and user experience of the web application will have a direct impact on keeping the visitors engaged and converting them into customers. So the business needs to ensure that its web application delivers quality and distinct user experience to each visitor. That is why; it must pick the right criterions to assess the application’s usability effectively. To effectuate usability testing of the web application the business must pick key criterions like UX design, performance, speed, readability, accessibility, navigability, and amount of time and effort required by the user to perform a particular task.
4) Scale the Load Tests Incrementally
Each business must replicate the production environment exactly to load tests web applications more effectively. So it must identify and eliminate all issues related to hardware and system configuration in the test environment. At the same time, it is also important for testers to perform the load tests incrementally. They must run tests initially by replicating a smaller number of distributed users, and increase the number of users gradually. The incremental load testing will make it easier for the professionals to identify the exact point where the application crashes. They can perform the load tests in cycles, and analyze the test results of each cycle to assess how the website performs under varying user loads.
5) Create Simple and Reusable Tests
The quality of tests will also have direct impact on the whole web application testing process. Often complex tests affect the workflow adversely, and make it difficult for testers to identify the cause of the problem. The testers must not try to test multiple features or functionalities of the website using a single test. They must write simple tests to check specific features or functionality of the application. They can simply divide the workflow into multiple tests, and write each test to assess a particular aspect of the web application rigorously. At the same time, the testers also need to design reusable tests to quickly access the application across various browsers and devices.
It is always important for the business to make a comprehensive strategy to ensure that all aspects of the web application are tested rigorously. Also, the testers must repeat the tests under various conditions to assess the application’s quality more accurately.
Security testing is very much self-explanatory. By the name itself one can figure out that it relates to a technique to strengthen the security. But is Security testing just a testing to protect data and information functionally?
It’s much more than that. Security testing hosts a whole lot of functionality. How well do we know about Security testing? Do we know enough about it? Well. It’s time for us to know about it since in this tech age, we are vulnerable to various breaches.
Security testing basically works on 6 principles:
These principles form the corner stone for any security test. In order to determine whether your security testing is successful or not. You have to rely on these principles. Sounds similar to that of resource management, but are quite the opposite.
- Confidentiality is a process where things are kept private. Not everyone or perhaps no third party is aware of the test. The matter is kept confidential within an organization.
- Integrity refers to protecting information so the unauthorized parties aren’t able to modify it.
- Authenticity showcases the legitimacy of any desired software.
- Authorization cannot be defined better than the access control which is under the hands of a particular individual.
- Availability refers to the assurance for the provision of information & communication services as and when required.
- Non- Repudiation is to avoid any conflict between sender and receiver on the basis of ultimate denial. That it when the Non-Repudiation principle comes into play.
The aforementioned principles were the basics of security testing. Let’s learn more about the process.
Every application that has been created has been done so with the help of a database. Structured Query Language (SQL) forms the basis for this. Now when all the above principles fall short somewhere. The language becomes vulnerable to the unauthorized sources.
Now this takes place due to several reasons. One of the major reason is an organization does not focus on the security aspects as much as it does on the other aspects such as infrastructure and access codes. The shortfall in the security aspects leads to its breach.
What is a Security Test?
Security Test is overly a process which is concerned with the testing of the security. And to ensure that the test turns out to be successful. There are four major steps to take care of.
- Data Access
- Network Security
In order for any modern day organization to work properly. It is pretty much mandatory for them to get these four things to a perfect place. A lack of any of these may cause serious concerns over the security of the database of a particular organization.
Data Access refers to the accessibility of any data. There are only a few people or a particular individual that is allowed or should be to access any important database. The data if falls in the hands of an unauthorized individual. It may lead to misuse which can turn out to be a horror for any organization.
Network security refers to the level at which a network is secured. There are various levels in network security. The important the data, the higher should be the level of network security.
Authentication refers to authenticity of any program. A stage where certain information is revealed to make sure that people are aware about who is heading or owning a particular program.
Encryption is some kind of common information. For example: specific password. Encryption is the last step of a security test and indeed the most pivotal one. If there is a short come in any of these parameters the test may turn out to be unsuccessful. In order to ensure smoothness. The importance of a security test is required to be understood before its too late.
