Cyber Security Specialist

Role & responsibilities

• Perform fuzzing of network protocols on devices like routers, Wi-Fi routers, ONT/OLT, firewalls, and other network appliances.
• Research and develop fuzzing strategies to test network protocols, identify vulnerabilities, and improve security.
• Work with tools such as Synopsys Defensics, AFL, Peach Fuzzer, or similar for fuzzing network protocols.
• Collaborate with hardware and firmware teams to understand device functionality and how to target fuzzing effectively.
• Analyze crash reports and debug logs to identify root causes of vulnerabilities and provide detailed remediation steps.
• Prepare technical documentation and reports on the findings from fuzzing activities.
• Stay updated with the latest security trends, techniques, and tools in network protocol fuzzing.

Preferred candidate profile

• Minimum 1 year of experience in fuzzing network protocols or security testing of network devices.
• Strong understanding of network protocols (e.g.TCP/IP, DHCP, DNS, HTTP, SIP, etc.).
• Experience with fuzzing tools (e.g., Synopsys, Defensics, AFL, Peach Fuzzer, Sulley, or custom fuzzers).
• Knowledge of network hardware, embedded systems, and operating systems.
• Familiarity with router, firewall, Wi-Fi router, ONT/OLT technologies, and associated protocols.
• Hands-on experience with debuggers, crash analysis, and memory corruption vulnerabilities.
• Solid understanding of network security concepts and vulnerability assessment techniques.
• Prior experience with security assessments and penetration testing of network appliances.
• Familiarity with scripting languages (e.g., Python, Bash) for automation of testing processes.
• Knowledge of reverse engineering and static/dynamic analysis of firmware.

Certifications (Optional but Preferred):

• OSCP, CEH, or other relevant security certifications.
