How resilient is your network? The latest edition of ENISA's Quarterly Review (EQR), 1st Quarter 2008, is now available online from their website. The theme for the review is resilience of communication networks.

The Editor, Panagiotis Trimintzios, defines resilience as "the ability of the network to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation. Resilience encompasses the availability of an infrastructure, i.e., its accessibility and usability according to certain performance specifications, but also its integrity, i.e., its ability to perform its intended function in an unimpaired manner, free from deliberate or inadvertent unauthorised manipulation. This includes the reliability of the networks and their ability to survive an attack or a fault."

ENISA -the European Network and Information Security Agency -  is an agency of the European Union.
