Your daily life

The Gennevilliers Campus is the heart of design, development, and support activities for major defense systems: radio communications, resilient network and infrastructure systems, satellite communications, collaborative combat, and cybersecurity. Located north of Paris, it is quickly accessible by public transport.

In a context where infrastructures and information systems face increasingly complex threats, ensuring their continuous security is paramount. Security Condition Maintenance (MCS) encompasses vulnerability monitoring, evaluation, and tracking of false positives and alert quality. This internship is part of a continuous improvement approach for security processes, risk reduction, and reliability of the tools used.

Your missions

You will be responsible for conducting a comparative study of MCS tools, according to several criteria, then analyzing the results to propose recommendations. Among the tasks:

State of the art

• Identify and document the main MCS tools
• Define comparison criteria (ease of installation and operation, ergonomics, cost, volume of false positives, etc.)

Implementation in a test environment

• Deploy and configure several solutions on a representative scope.
• Feed these tools with known vulnerability data (CVE).

Analysis of results

• Compare detected vulnerabilities vs. missed vulnerabilities.
• Identify false positives generated by each tool.
• Calculate metrics: detection rate, false positive rate, false negative rate, specificity/sensitivity, processing time, etc.

Synthesis and documentation

• Finally, produce a summary of the advantages/disadvantages of each tool according to the criteria.
• Propose orientations: which one(s) to integrate, possible improvements, configurations/practices to favor, etc.
• Potentially design a performance monitoring dashboard for the tools (KPIs).

Your profile

You are currently pursuing a BAC+5 level higher education specializing in IT/Cybersecurity.

You have skills such as:

• Basic knowledge in cybersecurity, and vulnerability management (CVE, CVSS, etc.)
• Familiarity with one or more vulnerability scanning tools
• Proficiency in a scripting language (Python, bash, powershell) to automate certain tasks
• Analytical rigor and critical thinking
• Ability to write clear documentation and present results.

A word from the team

This internship will be an opportunity for you to work in a team within an innovative company, to apply academic knowledge in an operational environment, and to develop new skills.

All our internships are conventioned and subject to remuneration, the amount of which is determined according to your level of study. As the position may require access to information classified as national defense secret, the selected person will undergo a security clearance procedure, in accordance with the provisions of articles R.2311-1 et seq. of the Defense Code and IGI 1300 SGDSN/PSE of August 9, 2021.
