Two consultants discussing a cloud computing performance report
Industry
  • Aerospace & Defence

 

Context
  • We were integrated into a project to secure an isolated IS for the "Defence & Security" domain.

Challenge

The aim was to support a team in charge of maintaining security conditions and involved:

  • Implementing an automated system for auditing the compliance of the equipment;
  • Rolling out an integrity check on the servers and workstations;

  • Writing a library to manage users in the directory and RDBMS;
  • Rolling out a HIDS on a platform and integration on the existing one.

Keys to success

  1. Our experience in security engineering work targeting certification;
  2. Our proven expertise in securing open source systems, architecture and integration of security COTS;
  3. Our ability of the contractor to work in a matrix organization with the support of other teams (system engineering, development and configuration management);
  4. Our good communication skills to champion architecture improvement proposals.
