Summary:Society is growing increasingly dependent upon large-scale, highly
distributed systems that operate in unbounded network environments,
which like the Internet, have no central administrative control and no
unified security policy. Despite the best efforts of security
practitioners, no amount of system hardening can assure that a system
that is connected to an unbounded network will be invulnerable to
attack. The discipline of network survivability and security can help
ensure that such systems can deliver essential services and maintain
essential properties such as integrity, confidentiality and performance,
despite the presence of intrusion. Unlike the traditional security
policies that require central control for instance or administration,
survivability is intended to address unbounded network environments.
Furthermore, since survivability requires robustness under conditions of
intrusion, failure, or accident, it includes the concept of fault
tolerance. This paper formulates the basic issues to be solved in this
new field, discusses and comments some current solution concepts and
finally outlines the most challenging future research avenues
