Are you in control?

Organizations are increasingly depending on information and supporting IT systems. Most companies document and implement adequate procedures to safeguard the confidentiality, integrity and availability of important information and IT systems.

The main question is: are all procedures effective on all critical systems?

There is only one way to know for sure: measure your performance and check if you're complying with your procedures.
