1. What are the critical elements of the API security checklist mentioned in the text?

The API security checklist includes using secure requests behind SSL/TLS, using basic code, input validation, sanitising data, conducting user privilege escalation tests, avoiding common vulnerabilities, handling quotas and timing throttling requests, using TLS headers to avoid SSL strip attacks, and standard authorisation methods.

2. Why is it important to conduct user privilege escalation tests?

User privilege escalation tests help to ensure that access or refresh tokens for one user are not accepted for another, preventing unauthorised access to sensitive information or functionality.

3. Could you please explain API security testing and its importance?

API security testing evaluates the security of an Application Programming Interface (API) to identify and address vulnerabilities. Protecting customer trust, preventing downtime, reducing costs, and avoiding legal implications is essential.

4. To what extent does security testing adhere to the six tenets?

The six security testing principles are confidentiality, integrity, authentication, availability, authorisation, and non-repudiation.

5. Tell me what each of the four categories of security testing entails.

The four types of security testing are network security, system software security, and client-side application security. Network security involves looking for vulnerabilities in the network infrastructure, system software security assesses weaknesses in various software operating systems, databases, and other applications, and client-side application security ensures that the client’s browser and tools cannot be manipulated.

6. Which API security issues are most often encountered?

Some common API security vulnerabilitiesinclude avoiding FORTAG, SQL injection with remote execution, broken object-level authorisation, broken user authentication, excessive data exposure, lack of resources, broken function mass assignment, security misconfiguration injection, improper access, privileged innovation, SQL injection, unauthorised data access, unauthorised data manipulation, cross-site scripting, and data manipulation.

7. For what reasons is it critical to check user imports while testing APIs?

Validating user imports in API testing helps to prevent malicious content from being introduced into the system, which could compromise security.

8. Explain TLS headers and why you should use them while testing APIs.

TLS headers are used to avoid SSL strip attacks, which can be performed by intercepting and decrypting an SSL/TLS connection. By using TLS headers in API testing, the connection between the client and server remains secure.

9. Please explain privilege escalation and why it is a security risk.

Privilege escalation is a security vulnerability where attackers gain elevated access or permissions beyond their intended level. This can lead to unauthorised access to sensitive information or functionality, making it a significant security concern.

10. What is encryption, and how does it relate to security testing?

Encryption is a security mechanism that protects data by converting it into a coded form that cannot be read without the proper decryption key. Security testing involves checking that encryption is implemented correctly and is used to protect sensitive information.

11. Tell me the difference between SQL injection and cross-site scripting.

SQL injection is an attack in which a single line of code is injected into an application’s input text box to gain unauthorised access to a database. Conversely, cross-site scripting involves accessing a web application and executing a script to steal user data or take control of their browser.

12. How does ethical hacking contribute to possible network or computer system risks?

Ethical hacking is identifying and addressing potential threats on a computer or network by simulating attacks. It allows malicious hackers to exploit system vulnerabilities before attackers with evil intentions can use them.

13. What is password tracking, and how can it be prevented?

Password tracking is guessing passwords to gain access to private or personal data. It can be prevented by using strong passwords and implementing two-factor authentication.

14. Can you explain penetration testing and why it is necessary?

Penetration testing attacks a computer system to identify security vulnerabilities and potential entry points for attackers. Its goal is to help organisations protect against real-world attacks by identifying and addressing weaknesses in their security posture.

15. In security testing, what exactly is risk assessment?

Risk assessment evaluates and decides on the risk involved in potential threats and vulnerabilities. It is an essential part of security testing, as it helps organisationsprioritise their security efforts based on the likelihood and impact of different threats.

16. Explain security auditing and how it differs from security scanning.

Security auditing systematically evaluates an organisation’s information system security. It involves reviewing policies, procedures, and controls to ensure that they effectively mitigate risks. Security scanning, however, is a program that communicates with web applications to identify potential security vulnerabilities.

17. In these three cases, how exactly does the idea of security testing apply??

The three scenarios covered by the concept of security testing are configuration, integrity, and availability. Configuration testing ensures that systems are configured correctly, integrity testing verifies the authenticity and accuracy of data, and availability testing ensures systems are accessible and responsive.

18. Why is OWASP being run, and what does it hope to achieve?

OWASP is an open web application security project that protects data from unauthorised users. Its goal is to help individuals prepare for security testing by understanding the top 10 vulnerabilities, their classification, and the tools used to identify and address them.

19. what exactly does the Information Security Management (ISM) group do when protecting sensitive data?

The ISM team is responsible for ensuring the confidentiality of data and protecting related activities. They are crucial in implementing robust security measures to protect against threats and vulnerabilities.

20. As far as information security is concerned, why is web application security so important?

Web application security is crucial because it allows access to the complete application functionalities, making it a prime target for attackers. Implementing robust security measures is essential to protect against potential threats and vulnerabilities that could lead to data breaches or other security incidents.

21. When it comes to web app security, what exactly is the primary emphasis?

The main focus of security testing for web applications is to ensure transaction security, encryption, and compliance with regulations. It covers the application’s front-end and back-end areas and implements appropriate violations for under-rupiah transactions.

22. To what extent can the risk assessment team determine which web apps are vulnerable to attack?

Around 80% of web applications are exploitable, meaning they have loopholes that can be identified and used to access other levels. The risk assessment team tests for this by evaluating the application at both the front-end and back-end levels using vulnerability assessment and penetration testing.

23. Can you tell me how penetration testing differs from vulnerability assessments?

Vulnerability assessment is used to identify loopholes in specific missions or systems, while penetration testing allows access to other levels through exploitable loopholes.

24. Explain the three categories of vulnerabilities and how each affects online applications’ safety.

Vulnerabilities are divided into confidentiality, integrity, and availability. Confidentiality is based on authentication and authorisation, integrity is based on data confidentiality, and availability refers to the application’s availability to log in and perform activities. Unauthorised users cannot edit it.

25. To stop unauthorised people from getting into online apps, what part does network security play?

Network security ensures that an attacker does not compromise an application within a minute by limiting requests to specific IP addresses, blocking repeated requests, and implementing proper firewall controls.

26. Who does the testing for network security, and what does each team do?

Network security is the responsibility of various teams, including the Network PD, SOC, and DLP teams. They perform data leakage prevention, social engineering testing, compliance testing, wireless security testing, and disaster recovery testing.

27. Which two stages of security testing are most commonly used to ensure the safety of online applications?

The two primary security testing levels for web application security are ability assessment and penetration testing.

28. Can you tell me the steps of the software development life cycle (SDLC) for security testing?

The SDLC in security testing involves the entire software development life cycle, including requirement analysis, design, development testing, command testing, deployment, and post-deployment stages such as post-design, SDR, secure design review, post-development, state testing, QA quality, functional testing, and DAST.

29. How does one go about addressing problems found during security testing?

After testing, the security testing team fixes at least ten critical issues and approves the deployment. Medium problems are also addressed if there is capacity to do so. If functional testing is completed, the team verifies and confirms the fix. The deployment process is done quarterly with the latest updates for each version.

30. When testing and security are finished, what is the primary motivation for applying updates, and what vulnerability was found six months later?

The main reason an application is updated is to address bugs. Six months after the testing and security were completed, an issue was raised regarding the Apache log upgrade.

31. To better defend against hackers, what exactly is the Open Web Application Security Project (OSP)?

The OSP is a pre-project that aims to protect against hackers. It offers a list of security tools, test cases, related books, sample codes, videos, presentations, and cheat sheets for identifying vulnerabilities and calculating risk ratings.

32. Why is identifying the user’s identity crucial in web application security testing?

Identifying the user’s identity is crucial in web application security testing, as changing the user’s identity can lead to security misconfiguration and errors.

33. Besides the other vital factors, which web application security testing option is the best?

Java scripting is the best option for web application security testing, as it is based on the scripting language and can be used to mitigate scripting language attacks. Serialisation is another crucial aspect of web application security testing, as it allows for the encryption or decryption of parameters within the application.

34. What tools are utilised when assessing the security of a web application, and what features do they have?

Test web apps for security using free ZAP and post-degree burp suite. Burp Suite’s community edition is free, whereas the professional edition costs about two lakhs per year for bits. Easy-to-use proxy tool Burp Suite detects vulnerabilities. The web suite tool sends browser-server requests. A 40-digit password is required for Burp Suite’s 1000-password front end. Intruders, scanners, and decoders increase web application security testing.

35. what does the manual testing course emphasise compared to automated testing?

While automation covers scanning, the APK Decompiler tool is 40%–50%, like mobile app and web-based testing. The professional tool includes scripts and payloads to help detect and execute scripts. Although security testing does not impact OS dependencies, mobile apps are dependent due to their simplicity and accessibility.
