The goal of these directives on the security and availability of telecommunication infrastructures and services is to specify the security requirements of the legislature so that the affected parties can provide these in a coordinated fashion and increase consumer confidence. In addition, the guidelines define minimum security levels which each telecommunication services provider should ensure in order to contribute to the reliability and availability of the national telecommunications network.
