Resilience of Public eCommunications Networks - Good Practice Guide: Network Security Information Exchanges (NSIE) - Jun. 2009  903.3 kB

The content of this guide has been created from research analysis and the aggregation of various good practice sources from a number of countries. It mainly aims to assist Member States and other relevant stakeholders in setting up and running Network Security Information Exchanges (NSIE) in their own countries. A longer term aim would be to support the development of common approaches and policies for information exchange so as to facilitate working relationships and understanding between each country's NSIE. This guide's intention is to pave the way for an accelerated deployment of national NSIE and consequently co-operation among public and private stakeholders at pan European level.

Stock Taking of Member States´Policies and Regulations related to resilience of public eCommunications Networks - Set. 2008  2.5 MB

The Stock Taking of Member States‘ Policies and Regulations related to Resilience of public eCommunications Networks is part of ENISA‘s Work Programme 20082. It aims at identifying at national level all relevant authorities (stakeholders) and focuses on their tasks, existing policy initiatives and regulatory provisions, exchange of information between authorities and providers, national risk management processes, and preparedness and recovery measures. The intention of the study and accordingly of the report is not to assess how well a country is doing or benchmarking Member States against each other. Far from it, instead it focuses on giving an accurate picture of the country‘s current situation. In turn, the issue is to provide an inventory that outlines the laws and regulations in place and, most importantly, how countries have managed to put the regulation into practice. This includes recommendations, best practice and other measures countries may have chosen to implement to improve resilience of their public e-communications networks.

Broadband Services: Economic and Environment Benefits - Out. 2007  352.9 kB

People around the world are becoming more and more aware of and concerned about changes in the atmosphere due to extreme weather events, melting glaciers, and changing ecosystems. As the Washington Post noted in a special report about global warming and climate change, “broad scientific evidence suggests that carbon dioxide and other greenhouse gas emissions have already triggered changes in the Earth’s climate and that more disruptive changes lie ahead.”2 The story discussed a range of costly and daunting measures to address the problem by reducing emissions. These include changes in waste and forestry management, building construction and transportation.

Device and Service Discovery in Bluetooth Networks - Jun. 2002  613.7 kB

Bluetooth has become the de facto standard for short range wireless communication. Over 2000 companies have registered their interest in the Bluetooth Special Interest Group (SIG). Although Bluetooth products are already being shipped, many aspects of Bluetooth are still uncharted territory. Among these are the timing of Bluetooth service discovery. Several companies are trying to adopt Bluetooth standard to a sort of mini cellular network to complement the existing 2G and 3G networks and even compete against them. These companies will have to consider several aspects of Bluetooth and the fact that the technology was not built with such systems in mind.

Secure Telecommuting for Shared Broadband Access Points  213.6 kB

This white paper explores the risks posed by home networking and shared broadband access, and explains why conventional telecommuter firewalls fail to provide complete protection. The paper then describes a new-generation VPN firewall, SonicWALL’s TELE3 TZX with an integrated 4-port switch that provides the first comprehensive, costeffective solution to the problem. The TELE3 TZX isolates an employee’s corporate computer from other household systems, shielding their VPN connection and the corporate network from vulnerable home networks. With the TELE3 TZX, network administrators can finally secure VPN endpoints easily and economically, even in heterogeneous home network environments.
