Computer question from Laboratory Attendant exam, 2026 by JKSSB
A cybersecurity researcher needs an operating system mainly for network testing, scripting, and advanced system customization, with strong command-line tools and open-source flexibility. Which operating system would be most suitable?
Last updated Jun 19, 2026
Correct Answer:
Option B —
Linux
Why this is correct:
Linux is the industry standard for cybersecurity research and penetration testing (with specialized distributions like Kali Linux or Parrot OS). It perfectly matches the researcher's requirements:
Network Testing & Scripting: Linux natively integrates powerful command-line utilities and scripting languages (like Bash and Python) essential for automating network tasks.
Open-Source Flexibility: Because it is open-source, researchers can modify the kernel, audit the code, and customize the environment down to the lowest level.
Why the other options are less suitable:
A) Windows: While it dominates the enterprise world, Windows is proprietary (not open-source) and tightly locked down, making deep system customization and kernel-level network manipulation much harder.
C) Mac OS: While it is Unix-based and has a strong command line, it is closed-source proprietary software tied strictly to Apple hardware, limiting deep hardware-level customization.
D) Standalone firmware OS: This refers to microcode or embedded software built into specific hardware components (like a router or smart appliance). It lacks the general-purpose environment, scripting ecosystem, and user tools needed for robust research.
