Ensuring that the developed software is free from any security issues is very important. Identifying potential vulnerabilities and resolving them is a challenging task. The growing developments in the software industry require the implementation of the best practices for effective security testing of the software.
Some of the best practices for the security testing of the software applications are:
1. Test beyond the Public Interfaces
In most cases of security testing, the inputs for an application come through the API of the application, or the public interfaces. This outweighs the inputs that come from the file systems and networks. This makes the software prone to attack owing to the easy access available to the sensitive data. This makes testing beyond just the public interfaces important to ensure optimum security of the software.
2. Look for the Unexpected
For effective security testing, testers must try finding the unexpected functionality issues instead of the usual testing the codes. Rather than simply testing the application software for the expected outcomes, testing for the unexpected behaviors or side effects in the design is more helpful. Looking for the unexpected helps in detecting the hidden vulnerabilities that are prone to exploitation by the attackers interested in accessing the important data of the software.
3. Check the Deployment Environment
It is a vital aspect to check the deployment environment for any configuration errors. A single error in the configuration during the setup process can put the security of the application in danger. In the case of deployment of the application to a server, it is important to check the security. The security of the server can be ensured through scanning for the open ports, reviewing the configuration files and ensuring the inability of the attackers to access the sensitive files over the server.
4. Static Analysis
Static analysis allows the inspection of the application codes without execution of the program in its rest state. The thorough examination of all the aspects of the source code helps in the identification of the potential flaws that can expose the application to attack. The use of the software analysis tools assists in finding the vulnerabilities that the developers may have skipped during the code review stage.

5. Dynamic Analysis
Dynamic analysis for security testing is performed while the software is in operation. The use of dynamic analysis tools can help the testers to find the hidden problems that can be difficult for static analysis tools to detect. The dynamic analysis tools can easily detect problems like file access issues or manipulation of memory.
6. Investigate the Incident Response Procedures
Testing the effective functioning of the incident response procedures is important. While testing the software security, running the breach simulation exercises can help in identification of the vulnerabilities that require immediate attention. Testing the incident response procedures helps remain aware about the fixing of problems and also regarding the development as well as the implementation of the security patch.
Building software with the use of the best security testing practices helps in avoid security problems and delivering value to the customers.
