By admin 16 Min Read

One of the critical parts of software development is security testing. It is very important because it plays crucial roles in identifying and cubbing the problems that software vulnerabilities may cause to the users and business owners. There are best practices in security testing that must be followed for security testing to be properly done.

In this article, we will be walking you through the best practices in security testing. Let us get started, shall we?

What is Security Testing?

Security testing identifies and addresses vulnerabilities and security risks in software. Security testing techniques can help secure application software and protect all sensitive data against external attacks and unauthorised access.

What Are the Best Practices In Security Testing?

Here are some best practices in security testing: 

  • Start Early: Starting early is an important step in security testing. You do not have to wait until the last stages of development or when your product is already in the market before you can begin testing
  • Understand the system architecture: Understanding the whole design of the software to be tested is crucial in security testing. It is a step that helps you see potential attacks before they occur.  Also, if you understand the architectural design, you can determine the best security testing methods and approaches. With this, you can also quickly identify any unexpected behaviours during testing. For example, knowing unanticipated behaviours and when someone is trying to access unauthorised data.

• Use a combination of testing techniques: A variety of automated and manual testing techniques make up some of the best practices in security testing. With these testing techniques, you can quickly identify vulnerabilities no matter how complex.

• Test Data Protection Level

Make sure to check the data protection level of your software. Doing this will help in protecting user data in all forms. 

• Test in different environments: Testing in different environments is one of the common best practices in security testing. This practice helps you ensure that your software can work well in different scenarios with developing security concerns for the users. To test your software in different environments, consider using different browsers, operating systems and networks.

• Perform penetration testing: You should not forget to simulate different forms of attacks on your software to single out all the vulnerable positions of your product. This will make it more difficult for attackers to take advantage of any security loopholes. We highly recommend that this test should be regularly performed with upgraded forms of security testing

• Involve security experts: Ensure that all the above best practices in Security testing are performed by experts with extensive experience in the field of security testing. Only expert testers can properly perform the right security tests, give detailed and useful reports/recommendations, identify and mitigate vulnerabilities.

• Document and prioritize vulnerabilities: Experts will always agree that documentation of test rest results is as important as testing. During documentation, ensure your testers know how to rate different vulnerabilities based on their levels of severity.

  • Check for Error Handling: Check for error handling pages to see what messages or data is returned. All corresponding error pages should not display a different message or data to users.
  • Test regularly: As we have mentioned earlier, one of the best practices in security testing is to perform regular tests. Do not forget, attackers are always upgrading their techniques, so it is only wise for you too to upgrade your testing skills and carry out more frequent security tests.
  • Session Management: Perform a robust security test with the session management of your software using multiple actions. See how long it takes for sessions to expire and if the users are automatically logged out as expected.

You can guarantee the security and integrity of software systems by following best practices in security testing.

How to Perform Security Testing

Wondering how to perform security testing? Here are some steps you can take to perform security testing:

  • Define the scope: it is very crucial to have a clear breakdown of the security test you are trying to do. This will help everyone on the team to know their roles and expected outcomes. Defining the scope goes a long way in helping to ensure that all important testing areas are well covered.
  • Identify potential threats: After defining the scope of your security test, you can easily point out the threats/attacks and vulnerabilities that your software may be exposed to.
  • Create test scenarios: The third step on how to perform security testing is to simulate test scenarios such as attacks. Doing this will expose the loopholes that may give room for attacks and data breach. 
  • Evaluate the results: The next step is to gather the results of the test scenarios so as to analyse how severe the vulnerabilities can be. While writing the report of this stage, it is important to arrange them based on their levels of risk so that the development team can do the needful.
  • Report and remediate: Right! At this stage you would have gotten your reports of the vulnerabilities and weaknesses of your software. The next move on how to perform security testing is to report them to the right team. Make sure you have prioritised them based on their levels of severity.
  • Repeat the process: Security testing is not a one-time process so in order to be safe, you must repeat the process, again and again and again. The best practices in security testing require you to perform these tests on a regular basis so as to keep you ahead of attackers and unauthorised access.

Using the Best Security Testing Tools: Best Practices in Security Testing

Cybersecurity requires the use of security testing tools to identify flaws. Security testing tools aim to find weaknesses in a system or network. It is overwhelmingly helpful in identifying and averting risks to people, companies, and security professionals.

Scanners for security

Tools for security testing come in a variety of forms. One example is scanners created to find security loopholes in computer networks and systems. They can identify potential weaknesses and offer possible solutions to lessen the dangers they introduce.

Tool for Penetration Testing

Another tool used to check for security flaws is the penetration testing tool. By simulating assaults, these tools enable testing of computer networks and systems for security weaknesses. Employing this technology allows businesses to evaluate their security posture more accurately.

Tool for Cracking Passwords

The strength of the passwords used to secure computers and networks is tested using password-cracking tools. With the aid of these tools, weak passwords that attackers can exploit by employing a variety of techniques to guess or break passwords can be identified and promptly corrected.

Network Security Tools

Network security tools perform different security-related functions, including identifying and blocking unwelcome intruders, locating and stopping suspicious vehicles, etc.

Web App Security Tool

Web application security tools help to protect apps from external threats and attacks. This tool should be used to test the security strength of the app regularly so as to take care of any vulnerability in the web app that may put the software at risk with hackers and bad actors. The security tool is also handy and active in protecting against data theft.

Security Testing Software

Security testing software are tools designed and created to easily identify vulnerabilities in computer systems, applications, networks, etc. Security testing software can be used to assess the security posture of a system in the following ways; 

  1. Simulating attacks
  2. Testing security controls
  3. Identifying vulnerabilities/weaknesses

Types of Security Testing Software/Tools

Software for security testing often comes in the following varieties:

Vulnerability scanners: These programs search for vulnerabilities in applications and networks and notify the user of them.

Penetration Testing tools. Penetration testing tools simulate attacks to find gaps in a system’s security defences.
