Job Title: Cyber Security Intern (Network Security, Vulnerability Assessment, Linux, Security Tools)

Company: Crossing Infotech

Location: Remote (open to candidates anywhere in India)

Employment Type: Full-time internship

Duration: 1 to 3 months

About the role

Every organisation has weak spots. The question is whether the people who find them are on your side or not. As a Cyber Security Intern at Crossing Infotech, you will learn how defenders think: how to review systems, spot risks early and explain them clearly so they get fixed before they cause damage. You will work in a controlled, authorised setup, practise on approved lab environments and learn the habits that responsible security professionals follow.

This is a hands-on, full-time remote internship for people who are curious about how systems fail, disciplined enough to stay within ethical and legal limits and patient enough to document what they find.

What you will do

- Learn and apply vulnerability assessment methods on approved lab systems and test environments

- Review network, server and application configurations for common security gaps

- Use security tools such as Nmap, Wireshark and Burp Suite Community in authorised practice setups

- Study common threats such as phishing, malware behaviour, weak passwords and misconfigurations

- Help monitor logs and alerts, and note unusual activity for senior team members

- Write clear risk reports with simple, practical recommendations for fixing each issue

- Support security awareness material and basic policy documentation

- Share progress in daily check-ins and weekly review sessions

What we are looking for

- Basic understanding of networking (TCP/IP, DNS, ports, firewalls)

- Working comfort with the Linux command line

- Awareness of common vulnerabilities such as those in the OWASP Top 10

- Familiarity with security tools or practice platforms such as TryHackMe or Hack The Box is a plus

- Certifications such as CEH, CompTIA Security+ or similar are a plus, not a must

- Strong ethics, discipline and respect for authorisation and confidentiality

- A stable laptop and reliable internet connection for full-time remote work

Who can apply

- Final-year students or recent graduates from B.Tech, B.E., BCA, B.Sc (CS/IT), MCA, diploma programs or related streams

- Self-taught learners who can show their skills through practice platform profiles, write-ups, projects or certifications

- Anyone available to work full-time for the internship duration

What you will gain

- Practical exposure to defensive security methods and tools

- Guidance and feedback from experienced team members

- Security write-ups and lab work you can show in future interviews

- Internship completion certificate

- Freedom to work from your own city

Schedule

Full-time, Monday to Saturday or as assigned by your reporting manager, with daily check-ins and weekly review sessions.
