Technical Skills & Experience

• 6. Can you explain the differences between symmetric and asymmetric encryption?
  Answer: Symmetric encryption uses the same secret key to encrypt and decrypt data, while asymmetric encryption uses a public key to encrypt data and a private key to decrypt it. Asymmetric encryption is more secure, but symmetric encryption is faster and more commonly used for everyday data protection.
• 7. Have you worked with any cloud security platforms? If so, which ones?
  Answer: Yes, I have experience working with cloud security platforms such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform. I am also familiar with their security features and best practices for securing data and applications in the cloud.
• 8. Can you explain the concept of least privilege?
  Answer: Least privilege is a security principle that ensures each user or system has the minimum level of access required to perform their job or function. This reduces the risk of unauthorized access and limits potential damage in case of a security breach.
• 9. How do you conduct vulnerability assessments?
  Answer: I follow a systematic approach by conducting a network scan, analyzing the results, and identifying vulnerabilities. I then prioritize the vulnerabilities based on their severity and develop a plan to remediate them. I also perform manual testing to validate the vulnerabilities.
• 10. Have you worked with any intrusion detection systems (IDS)?
  Answer: Yes, I have experience working with IDS such as Snort, Suricata, and Bro. These IDS help in detecting and preventing unauthorized access, attacks, and malicious activities within a network.

• 12. Can you give an example of a time when you had to adapt to a new technology or process quickly?
  Answer: In my previous role, our company implemented a new security information and event management (SIEM) system. I learned the system and its features in a short amount of time and successfully integrated it into our security operations.
