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.
