Web applications have provided a convenient way for businesses to offer better services to the customers. However, security is one of the biggest concerns while developing an app as even a minute vulnerability can provide a backdoor for the hackers to initiate a malicious attack. It is important to have a strategic testing procedure throughout the app development process. The process involves an in-depth analysis to identify the technical flaws or security vulnerabilities in the app and subsequently repair them. It ensures that the app can adequately protect important data and serve its intended functionality.
Given below is a complete checklist for application security testing:
Threat modeling is the first and most crucial step in testing a web application’s security. It involves analyzing the application bit-by-bit to map down the entry points, data flow and identify the exact location of the existing vulnerabilities. Thread modeling also includes ranking the vulnerabilities in order of severity and devising suitable countermeasures for the same.
Proper authentication mechanism is important to eliminate the risk of a brute force attack, making sure that only the authorized users and servers can have access. It should be verified that account suspension mechanism is working accurately and triggers a lock-out after repeated failed login attempts. Testing can be done by entering wrong combinations of username password till the account gets locked.
Access To Application
After the user’s login credentials have been authenticated by the application, the next thing to determine is the type of data he can or cannot access. Superfluous elevated rights can pose a risk of data breach. You can create multiple user accounts and set different access rights for each of them. After this, login with all the accounts and try to access the modules, screens, forms as well as menus. If any security issue is found, it needs to be corrected immediately.
Session hijacking attacks are quite common in web applications. Hackers may attempt to steal the cookies of an already authenticated session to get control of the user’s access rights. In another form of session hijacking, the hacker may also passively capture the login credentials of the user. In order to protect the app users’ information, make sure that the cookies do not contain any sensitive information. Also, the session IDs should be unique and generated randomly after authenticating the user’s identity.
