A brink of failure and breach of security detection and recovery system

An integrated framework for the assessment of network operations, reliability, and security

“…Service reliability may be degraded by breach of security (BOS) events and by events that lead to BOF states [9]. A network is in a BOF state when a failure will occur within a short period of time.…”

“…A BOS is considered to be an exploitation of a weakness in a network resulting in unauthorized access to, unauthorized modification or compromise of, or denial of access to information, network monitoring capability, or network control capability [9]. All aspects of BOS events will not be addressed here; rather, to illustrate the application of the reliabilitybased process, we present a simplified model that includes denial of service due to software vulnerabilities and denial-of-service attacks by internal or external malicious hackers.…”

“…As defined previously, BOF is a major event or a sequence of events that can affect a large number of end users (e.g., call blocked) or cause the failure of a critical functionality (e.g., E911 service) or both [9]. BOF is classified in this paper as a security issue, because, if not resolved or rectified properly, it may lead to a network-wide outage that can jeopardize the security of the system.…”

“…BOF is classified in this paper as a security issue, because, if not resolved or rectified properly, it may lead to a network-wide outage that can jeopardize the security of the system. For example, if, because of BOF, a network path is not available and traffic is rerouted to other path(s), this may cause congestion or buffer overflows through which hackers can gain access to the network [9].…”
