Implementation of Hardening Measures for the central Infrastructure

09/2007 - 10/2008

For ca 140 central server systems of a Frankfurt banking house, the implementation of hardening measures was planned and managed.

The systems were hardened against unauthorized use and any kind of unwanted access. The highest security level possible was implemented on the systems.

To provide for coordination and cooperation between principal and agent, interacting processes on either side needed analysis and adequate coordination. For this purpose, we developed a tool to depict the complete workflow (ca 20.000 unique actions) and allow both for detailed planning and informative reporting.

Operating System Updates on Central UNIX Servers

05/2007 - 03/2008

Ca 120 servers of the central infrastructure of a Frankfurt banking house needed to be updated to the latest OS standards.

The implementation needed to be executed without interfering with the production.

Thus, the extensive development of failproof fall-back scenarios and desaster-recovery procedures was a core task of this project.
