About the Role

This is a Project Intern role within the Network Security team. The internship offers impactful short-term projects, providing a glimpse of professional real-world experience and practical skills through on-the-job learning. The successful candidate must commit to at least a 3-month internship. Applications are reviewed on a rolling basis.

Key Responsibilities

  • Enhance the intelligent capabilities of the Web Application Firewall (WAF) to defend against sophisticated automated threats and large-scale application-layer attacks.
  • Intelligent CC (Challenge Collapsar) Mitigation: Research and develop automated mechanisms for dynamic threshold setting using real-time traffic analysis to improve precision against HTTP flood attacks and reduce manual configuration.
  • Smart Bot Behavior Detection: Implement advanced behavioral analysis to distinguish between legitimate users and malicious bots by analyzing request patterns and identifying anomalies.
  • Operational Efficiency & Accuracy: Optimize the WAF's adaptive learning capabilities to minimize false positives and improve the identification of evasive "gray market" activities.

Requirements & Tech Stack

  • Undergraduate or Postgraduate pursuing a degree/master in Computer Science, Computer Engineering, Information Systems, or other STEM disciplines.
  • Familiarity with common security concepts, vulnerabilities, and exploitation techniques.
  • Experience with at least one programming or scripting language (e.g., Python, Go, Java, JavaScript, C/C++).
  • Problem-solving mindset, self-driven attitude, and ability to work collaboratively in a fast-paced environment.

Preferred Qualifications

  • Participation in CTF competitions, bug bounty programs, or similar hands-on security challenges.
  • Published vulnerabilities (e.g., CVEs) or contributions to security research/tools.
  • Familiarity with cloud and container security, network security, or mobile application security.
