As to the problem approach was qualitative and quantitative. The study was carried out with five managers responsible for information security and 57 IT users in the CINDACTA II. We concluded that the CINDACTA II Information Security management is at a level that meets the requirements of NBR 27002:2013, as well as the publications of COMAER and Federal Public Administration.
