Cybersecurity worldwide has become a challenge for organisations and individuals to be protected against all attacks and malware. Working closely and directly with cyber-attacks and attackers has become a challenge to be updated with all new zero-day threats and vulnerabilities. The cybersecurity teams have been facing challenges in examining the advisory tactics, techniques, and procedures (TTP) and what are Indicators of Compromise (IOCs) can be used in addressing these issues. Other than this, incorporating the most suitable cyber security framework can assist in dealing with these technological threats. A direct relationship exists between threat intelligence and artificial intelligence, which contributes to addressing technological threats and protecting the necessary assets and information. Cyberspace and other technological software highly contribute to addressing this issue.

The authors investigate the propagation of picosecond pulses through Semiconductor Optical Amplifiers using the measurement technique of Frequency Resolved Optical Gating by applying pulses of varying peak power, pulse width and shape. Frequency Resolved Optical Gating is a relatively new measurement system which provides complete characterisation of the pulses in both the temporal and spectral domains. We examine the pulses before and after amplification through the Semiconductor Optical Amplifier. The work shows pulse broadening, the formation of large pulse pedestals, and the generation of significant frequency chirp across the pulse in the temporal domain. In the spectral domain results exhibit spectral broadening and a shift to longer wavelengths. These properties of the output pulses would cause serious degradation in high-speed communications systems employing Wavelength Division Multiplexing and Optical Time Division Multiplexing. The resulting physical properties occurring to the pulses due to propagation through the Semiconductor Optical Amplifier are a result of Self Phase Modulation, which is due to gain saturation induced by carrier depletion and carrier heating.

Virtual cluster environments in cloud computing offer significant advantages, particularly in terms of scalability, resource flexibility, and optimization. However, these benefits are accompanied by distinct security challenges that must be addressed. This research employs the PRISMA methodology to conduct a comprehensive systematic literature review, aimed at identifying critical vulnerabilities within these environments. By analyzing existing security countermeasures proposed in the literature, this study seeks to bridge the gap between theoretical frameworks and practical applications in securing virtual clusters. Furthermore, this paper aims to critically assess the strengths, weaknesses, and potential threats that virtual clusters pose to cloud computing infrastructures. It thoroughly examines specific security challenges impacting various types of virtual clusters and evaluates potential solutions designed to mitigate these risks. In addition, a detailed performance evaluation of these countermeasures was conducted through their implementation on a cloud-based virtual cluster. This practical evaluation provides valuable insights into the effectiveness of the security measures. Ultimately, this research seeks to offer concrete recommendations for enhancing the security posture of virtual clusters, thereby contributing to the overall security of cloud computing systems.

This paper presents “DynFire,” a novel approach for the role-based, dynamic control of network firewalls. DynFire allows an individually controlled, secure access to the ITresources of a large organization, with particular focus on mobile users and users with restricted rights, such as subcontractors. The basic assumption behind DynFire is that, within a secured network domain separated from the Internet, we can establish a temporary binding between an IP address and a single user ID. Whenever a user connects to or disconnects from this secure network domain, firewalls are configured accordingly, using a centralized “Firewall Manager” and standardized signaling protocols.

Midimew Connected Torus Network for Next Generation Massively Parallel computer System

Procedia computer Science 2021年 179卷 590-597页

作者： Maryam Manaa Al-Shammari Asrar Haque M.M. Hafizur Rahman Dept. of Computer Science CCSIT King Faisal University Al Hassa 31982 Kingdom of Saudi Arabia Dept. of Computer Networks & Communications CCSIT King Faisal University Al Hassa 31982 Kingdom of Saudi Arabia

Important scientific and engineering applications need high performance computing. This can be provided by massively parallel computer (MPC) systems. A sensitive step of maintaining such systems is the interconnection network used to interconnect the computing nodes. The topology used effects the network costs and performance significantly. Hierarchal interconnection networks (HIN) were introduced having several attractive features including low latency, low cost, and high fault tolerance. This paper proposes a new HIN called Midimew connect Torus Network (MTN) that provides constant node degree, high arc connectivity, high fault tolerance and a reasonable bisection width. Static network performance evaluation for the proposed MTN has been conducted and compared with other networks. The comparison included conventional topologies such as 2D Mesh and 2D Torus and hierarchal ones which are TESH and TTN. The comparison of result shows that with the cost of extra communication links MTN attains higher fault tolerance than that of TESH and mesh networks, and equal to that of TTN, and less than that of torus network. Also, the hierarchical networks such as MTN, TTN, and TESH yield moderate bisection width; and the bisection width of MTN is lower than that of mesh and torus networks. This paper shows the superiority of the proposed MTN by comparative study of static network performance.

In this paper, we investigate a new pattern mapping method to convert the assembly code between two VLIW digital signal processors. The method is so named because the pattern of the code is kept unchanged during the conversion process in order to manage complexity. As a case study, we first manually convert the assembly code of a typical DSP application from Texas Instruments' TIC62, the source processor, to a high level intermediate code. We then feed the intermediate code to the SCI40 compiler backend to generate the assembly code of the target SC140 processor, which is executed on the SC140 simulator. The result thus obtained compares favorably with that obtained directly by compiling and executing the C code on the SCI40 system in terms of both validity and total execution cycles. © 2002 IEEE.

Due to its many uses and ability to save and restore data, whether for businesses or individuals, cloud computing has become one of the mainstays in the technology world over the past few years. However, the limitations on speeds and sizes as well as the evolving of the Internet of Things made it challenging to rely on the cloud due to the extremely slow data processing. Therefore, to store and interpret the massive amount of data rapidly, programmers switched towards a new technology which is fog computing. This mini survey paper will outline fog computing as an integral part of cloud and edge computing for improving security and data protection. A systematic literature review of selected research papers that include findings and algorithms used to enhance security-related problems such as availability, latency, and intrusion detection will be discussed. This mini review paper finds out a state-of-the-art on the cybersecurity issues in fog computing using blockchain.

Resource sharing in mobile wireless networks has been employed to reduce costs, extend coverage, and ease the entry of new players in the market. The introduction of programmability and virtualization is expected to amplify these benefits of resource sharing. In this paper, we study a new virtualization-based paradigm for resource sharing in mobile wireless networks. Specifically, we consider the problem of resource allocation, particularly when user demands are uncertain. We formulate several two-stage sequential stochastic allocation schemes that provide tradeoffs between cost and user satisfaction. These allocation schemes are studied under different resource provider pricing models. Our simulations demonstrate that: First, while reducing cost significantly, virtualization considerably improves user satisfaction, and virtualization gains increase with the number of operators that share resources. Second, the improvements in cost, user satisfaction, and resource usage increase substantially with the level of user clustering. © 2016 IEEE.

This paper proposes the possibility of reuse of the existing optimized DSP code on a scalable high-performance VLIW DSP processor. Since loops are the critical paths in most DSP applications, we focus on issues related to loop optimization. In our approach, we first perform a loop alignment transformation on the source level;we then reuse the existing optimized loop code on the assembly level. The approach is highly portable because it is independent of DSP hardware details. It can be used directly by a DSP programmer on the source level and/or by a DSP compiler designer to implement independent optimization modules. © 2000 IEEE.
