Define HTTPS protocol and its security features
This question tests your knowledge of secure web communication standards and the cryptographic protocols underpinning internet security. It is essential for backend and frontend roles.
Why Interviewers Ask This
Security is paramount in e-commerce platforms handling sensitive user data. Interviewers want to verify you understand encryption, authentication, and data integrity. This ensures you can implement secure APIs and protect user privacy effectively.
How to Answer This Question
Define HTTPS as HTTP over SSL/TLS. Explain the handshake process involving certificates. Mention symmetric and asymmetric encryption roles. Discuss integrity checks via MACs. Highlight the importance of certificate authorities and avoiding man-in-the-middle attacks.
Key Points to Cover
- SSL/TLS encryption layers
- Certificate authority role
- Handshake process steps
- Data integrity verification
Sample Answer
HTTPS stands for Hypertext Transfer Protocol Secure, which encrypts data transmitted between a client and server using SSL/TLS. It ensures confidentiality, integrity, and authenticity of communications. During the handshake, asymmetric encryption exchanges keys, followed by symmetric encryption for data transfer. Digital certificates issued by trusted CAs verify server identity. This prevents eavesdropping and tampering, making it essential for secure transactions on e-commerce sites.
Common Mistakes to Avoid
- Confusing HTTP with HTTPS
- Omitting certificate details
- Ignoring encryption types
