Interview with Jan van Bon
Traditional security projects show a high degree of falling back specifically because they are not embedded in a well-functioning management system – says Jan van Bon. Creating a solid and practical architecture under your IT management approach can greatly reduce the cost of improving quality, and it can speed up your projects. An integrated approach requires a simple and straightforward method that is easy to understand, supported by available tools in the market, and accepted by many providers. This kind of approach requires thorough knowledge and sincere dedication.
