8. How does DevSecOps handle vulnerability assessment and management?

DevSecOps integrates automated vulnerability scanning into the CI/CD pipeline to identify vulnerabilities in the code and libraries.

9. What role does static application security testing (SAST) play in DevSecOps?

SAST analyzes the application’s source code to identify vulnerabilities early in the development process.

10. How can dynamic application security testing (DAST) improve security in DevSecOps?

DAST involves testing running applications for security vulnerabilities and potential exploits, providing real-world insights into application security.

11. Describe the purpose of “container security” in DevSecOps.

Container security focuses on securing applications and their dependencies within containers, ensuring that they are isolated and well-protected.

12. How does DevSecOps handle secrets and credentials management?

DevSecOps employs secure vaults and secrets management tools to protect sensitive data like passwords and API keys.

13. What is “shift-right” security testing in DevSecOps?

Shift-right involves ongoing security testing in production to identify and address vulnerabilities and threats that might emerge after deployment.

14. How does DevSecOps handle compliance and regulatory requirements?

DevSecOps automates compliance checks and ensures that applications adhere to relevant regulations throughout the development lifecycle.

15. Explain the concept of “continuous monitoring” in DevSecOps.

Continuous monitoring involves actively tracking applications and infrastructure for security threats and anomalies to ensure ongoing protection.

16. What are some common security challenges faced in a DevSecOps environment?

Challenges may include finding the right balance between speed and security, integrating security into existing processes, and educating teams about security best practices.

17. How does DevSecOps support the “least privilege” principle?

DevSecOps enforces the principle of least privilege by granting only the necessary permissions to applications, reducing the attack surface.

18. Describe the role of “security champions” in DevSecOps.

Security champions are individuals within development teams who advocate for security practices, help with security-related tasks, and raise awareness.

19. What is “continuous security testing” in DevSecOps?

Continuous security testing involves automatically testing applications for vulnerabilities as part of the CI/CD pipeline, ensuring ongoing security assessment.

20. How can DevSecOps help with incident response and recovery?

DevSecOps integrates incident response processes into the development workflow, facilitating quicker identification and mitigation of security incidents.

21. What is Vagrant?

A vagrant is a tool which can create and manage virtualized environments for testing and developing software.

22. What is the use of PTR in DNS?

Pointer record which is also known as (PTR) is used for reverse DNS lookup.

23. What is Chef?

It is a powerful automation platform which transforms infrastructure into code. In this tool, you can use write scripts that are used to automate processes.

24. What are the prerequisites for the implementation of DevOps?

Following are the useful prerequisites for DevOps Implementation:

At least one Version Control Software

Proper communication between the team members
Automated testing
Automated deployment

25. Name some best practices which should be followed for DevOps success.

Here, are essential best practices for DevOps implementation:

The speed of delivery means time taken for any task to get them into the production environment.
Track how many defects are found in the various
It’s important to measure the actual or the average time that it takes to recover in case of a failure in the production environment.
The number of bugs being reported by the customer also impact the quality of the application.

26. Explain SubGIt tool

SubGit helps you to migrate SVN to Git. It also allows you to build a writable Git mirror of a local or remote Subversion repository.

27. Name some important network monitoring tools

Some most prominent network monitoring tools are:

Icinga 2
