In order be risks, above must scheduled dynamically so system adaptive meet day-to-day stochastic demands on (both size...

Vulnerability remediation is a critical task in operational software and network security management. In this article, an effective vulnerability management strategy, called VULCON (VULnerability CONtrol), developed evaluated. The strategy based on two fundamental performance metrics: (1) time-to-vulnerability (TVR) (2) total exposure (TVE). takes as input real scan reports, metadata about the discovered vulnerabilities, asset criticality, personnel resources. uses mixed-integer...

Cybersecurity threats are on the rise with evermore digitization of information that many day-to-day systems depend upon. The demand for cybersecurity analysts outpaces supply, which calls optimal management analyst resource. Therefore, a key component defense system is scheduling its analysts. Sensor data analyzed by automatic processing systems, and alerts generated. A portion these considered to be significant , requires thorough examination analyst. Risk, in this article, defined as...

A Cybersecurity Operations Center (CSOC) performs various tasks to protect an organization from cyber threats. Several types of personnel collaborate function effectively as a team analyze the threat signals, in form alerts, arriving sources. Teams are often formed ad hoc, resulting imbalance their performances and thereby increasing risk associated with low-performing teams. The current approach taken by behavioral scientists forming effective teams focuses on first qualitatively assessing...

Existing approaches to cyber defense have been inadequate at defending the targets from advanced persistent threats (APTs). APTs are stealthy and orchestrated attacks, which target both corporations governments exfiltrate important data. In this paper, we present a novel comprehensibility manipulation framework (CMF) generate haystack of hard comprehend fake documents, can be used for deceiving attackers increasing cost data exfiltration by wasting their time resources. CMF requires an...

Modern botnets can persist in networked systems for extended periods of time by operating a stealthy manner. Despite the progress made area botnet prevention, detection, and mitigation, continue to pose significant risk enterprises. Furthermore, existing enterprise-scale solutions require resources operate effectively, thus they are not practical. In order address this important problem resource-constrained environment, we propose reinforcement learning based approach optimally dynamically...

Advanced cyber attackers can penetrate enterprise networks and steal critical documents containing intellectual property despite all access control measures. Cyber deception is one of many solutions to protect after an attacker penetrates the network. It requires generation deployment decoys such as fake text. The comprehensibility a text document affect required time effort for attack succeed. However, existing cybersecurity research has given limited attention exploring features...

Cognitive Radio Sensor Network (CRSN) is known as a distributed network of wireless cognitive radio sensor nodes. Such system senses an event signal and ensures collaborative dynamic communication processes over the spectrum bands. Here, concept Dynamic Spectrum Access (DSA) denes method reaching progressively to unused range band. As among essential CRSN user types, Primary User (PU) has license access On other hand, Secondary (SU) tries eciently, by not disturbing PU. Considering that...

Flight delays have a significant impact on the nationpsilas economy. Taxi-out in particular constitute portion of block time flight. In future, it can be expected that accurate predictions dasiawheels-offpsila may used determining whether an aircraft meet its allocated slot time, thereby fitting into en-route traffic flow. Without taxi-out prediction for departures, there is no way to effectively manage fuel consumption, emissions, or cost. Dynamically changing operations at airport makes...

Wavelet-based multiscale analysis approaches have revolutionized the tasks of signal processing, such as image and data compression. However, scope wavelet-based methods in fields statistical applications, process monitoring, density estimation, defect identification, are still their early stages evolution. Recent literature contains some applications tool-life bearing monitoring ultra-precision processes. This paper presents a novel application method nanomachining [chemical mechanical...

Intrusion detection systems (IDSs) analyze data that are collected by sensors, which monitor the network traffic. Any alert generated IDS is transmitted to a cybersecurity operations center (CSOC), performs important task of analyzing alerts. In order deliver strong security against threats, an efficient CSOC requires following characteristics: 1) all alerts must be analyzed in timely manner; 2) there ideal mix analyst expertise levels organization because quality analysis performed depends...

Flight delay is one of the pressing problems that have far-reaching effects on society and nation's economy. A primary cause flight in National Airspace System high taxi-out times (time between gate push-back wheels-off) at major airports. Accurate prediction time needed to make downstream schedule adjustments for better departure planning, which could mitigate delays, emissions, congestion ground. However, accurate difficult because uncertainties associated with dynamically changing airport...
