This process is important because software testing remains an integral challenge for all testing engineers. It is important to ensure that the software behaves appropriately even in cases of malicious attacks. The security experts understand the logic and specifications implemented in the web application and analyze all possible scenarios that can threaten the integrity and security of the application. 

Different Types of Security Threats Faced By Web Applications

The most common security threat types that most web applications face include: 

  • Injection attacks: A website that is vulnerable to injection attacks accepts untrusted data without any sanitation check. This attack is done by typing a code in the input field to trick the server into taking it as a system command and following the command of the attacker.
  • Broken authentication: Authentication risks are when session management and authentication tokens are not adequately implemented. This way the hackers can make claims over the identity of a legitimate user.
  • Cross-site scripting: Under this type of attack, the attackers inject malicious code into a website to reach the victim’s browser eventually.
  • Security misconfigurations: This attack occurs when the users forget to change the default settings such as passwords, error messages, reference IDs, etc. 

To counter these security breaches, web application security testing is crucial. Let us look at the key benefits derived from the process of web application security:

  • Reduced risk of attacks: The testing process makes it possible to scrutinize the application development and identify weak areas before the cyber attackers get a chance to do so.
  • Minimized business disruptions: Constantly monitoring the web application security helps identify the problems in time. This ensures that the deployment takes place as planned without any delays due to security or functional concerns.
  • Confidence boost: It is integral to ensure that there is complete data security to gain the trust of the customers as well as the businesses you partner with.

Now let us look at ways in which to identify common vulnerabilities and threats. These include: 

  • Watch your network: It is integral to scrutinize your network to scan it the way an attacker would. It helps you stay aware and understand the weaknesses of your system.
  • Penetration testing: Penetration testing is a process of deeply studying your functioning to analyze places where a possible attack could occur and identify the weak spots.
  • Manage permissions: It is crucial to segregate the network so that not every information is available to all the company employees. Manage permissions to control who can access what and when.
  • Use a firewall: Firewalls are integral to keeping external users from accessing your network. It must be used both internally and externally.

While these are certain industry-standard security measures, it is integral to tailor them based on your usage. Studying and understanding your web application and onboarding a web development team can help you identify the weak spots that the attackers might target. Once the spots are identified, the next step is to build a tailored strategy to cater to the weak spots and make your web development foolproof. 

Web Application Security Testing Checklist

Based on the above-mentioned security threats and concerns, here are some proven security tests that cover all potential security concerts of your web development: 

1. Authentication and Authorization Testing

Authentication is the strongest pillar as it verifies the identity of the users who will interact with your web application. Without a strong authentication in place, illegitimate users can gain access to the website. Strong password policies, multi-factor authentication, password storage, and account lock mechanisms are crucial measures that can help strengthen authentication. 

Secondly, authorization is important to ensure that only authorized users get access. Role-based access controls, session management, and audit trails can help fix problems related to authorization and add a security layer. 

2. Input Validation Testing

As small as a photo or a video uploaded can bring in trouble if it is not properly identified. It can lead to your website’s sensitive data being exposed or a breach of data. As a result, it is crucial to verify every little piece of information that is entered by the users to build a safe online environment. 

To do this, you can enable whitelisting that only allows the accepted people to access the web development and blocks all others. You can also likewise blacklist the spammers or dangerous characters and patterns. Lastly, you can also do a regular expression validation to ensure that the user input matches the expression setup. 

3. Session Management Testing

Session management refers to the process of establishing and managing the sessions determined by the system. They store data temporarily for the user of the website such as usernames, passwords, shopping carts, etc. 

It is integral to instate and modify cookies that hold valuable information as part of the session management testing process. Further, ensure that there is randomness to curb the utilization of the information by attackers. 

4. Error Handling and Exception Testing

Error handling is yet another important aspect of ensuring web security. Errors such as the password entered being incorrect attract cyber attackers. Instead of using an incorrect password error message, it is recommended to use the error messages such as invalid username or password. Keep the error messages as concise as possible and do not give out any sensitive details in these messages. 

5. Data Security Testing

Regular security scans are also integral to ensure that the security of your web development is intact. Automatic scanners run security checks daily or on an on-demand basis to maximize safety. You can also use penetration testing which is a manual process to identify the areas of security concerns. These testers can also be tailored to ensure that all your requirements are met and the web development remains secure. 

6. Configuration Management Testing

Configuration management refers to the process of overseeing the items that make up the software such as data, hardware, codes, test scripts, etc. This testing refers to the process of constantly overseeing the process to ensure that the items are managed and secured throughout the lifecycle of web development. 

7. Cryptographic Security Testing

Data encryption is important to ensure that the transfer of data is safe. It keeps information safe from attackers and ensures a risk-free transfer. To ensure the data is safe, follow SSL/TLS to encrypt data between the users and the servers.
