Interview Flashcards
Why is network security important?
Network security is importance to protect sensitive data from unauthorized access, prevent hacker, and ensure systems run smoothly.
Please explain SQL Injection briefly and describe how to prevent it.
SQL Injection is when attackers insert symbol code into database queries. To prevent it, I use prepared statements, parameterized queries, and always validate user inputs.
Do you know what secure coding is?
Secure coding means writing code that avoids vulnerabilities. For example, validating user inputs ensures no malicious data enters the system.
What is an API, and can you share your experience using one?
An API allows different systems to communicate. I used a REST API in a project to fetch and display real-time data in a web app and mobile app.
What is HTTPS, and how is it different from HTTP?
HTTPS is a secure version of HTTP. It encrypts data, so it’s safe from hackers during transmission.
What is a DBMS?
A DBMS is software that stores and manages data. I’ve used POSTGRESQL to handle data for a web application, including creating and querying tables.
Please explain the advantages and disadvantages of Micro Service Architecture (MSA) as you know it.
Microservices are scalable and allow independent development, but they can be complex to manage and require efficient communication between services.
What should developers pay attention to in order to avoid creating insecure websites?
I ensure inputs are validated, outputs sanitized, and sensitive data encrypted. I also follow secure coding standards.
How do you approach learning a new technology or programming language?
I start with official documentation, follow tutorials, and apply it by building small projects to practice.
When you encounter errors or issues during development, how do you resolve them?
I debug using logs and research solutions online. For example, I fixed an API connection issue by identifying and correcting a misconfigured endpoint.
Have you ever faced challenges while working on a team project? How did you resolve them?
In one project, roles were unclear, causing delays. I suggested a team meeting to clarify tasks, which helped us work more efficiently.
When developing a feature, what methods do you use to improve its performance?
I optimize code, use caching, and profile the app to fix bottlenecks. For example, I sped up a query-heavy app by adding indexes.
What skills do you think are important for a developer working at a security solution company like Hunesion?
Secure coding, understanding encryption, problem-solving, and staying updated on new security threats are crucial.
What do you think is the most fundamental consideration when developing security software for a company?
The most important consideration is ensuring data confidentiality, integrity, and secure access.
What precautions should you take when processing user-provided data?
I validate and sanitize user inputs to prevent attacks like SQL injection and XSS.
