International Conference on Parallel and Distributed Systems (ICPADS)

作者： Vagner Nascimento Carlos Gomes Waldir Moreira Antonio Abelém Post Graduate Program in Computer Science Federal University of Para Belem Para Brazil

The Transmission Control Protocol - TCP has been widely researched in many different networking technologies such as wireless, optical, satellite, sensor, and wired since it is the most used protocol on the Internet. In Wireless mesh networks, this protocol still has challenges due to its origin and implementations for wired networks. This paper proposes an adaptation on the congestion control mechanism using information from the network layer to improve TCP performance through the vertical calibration across layer technique. The result is the Cross Layer Mesh - Transmission Control Protocol (CLM-TCP). To show the efficiency of the proposal, simulations in the NS-2 were carried out.

International Journal of Network Management 2007年第4期17卷 287-294页

作者： Da Silva, Paulo Fernando Westphall, Carlos Becker Network and Management Laboratory Post-Graduate Program in Computer Science Federal University of Santa Catarina Florianópolis Brazil

This paper presents a model for response interoperability between intruder detection systems (IDSs), compatible with the model for alert interoperability developed by the Intrusion Detection Working Group (IDWG). Alterations in IDS IDWG architecture are proposed in order to provide for response interoperability support. The development and testing of the proposed model and its components are also presented.

The main issue related to Software-Defined Network emulators is how to replicate real behavior in experiments. Mininet and others SDN emulators have an architecture that limits both the scope of experiments and the fidelity of networking tests. Consequently, the serialization, contention, and load of background processes may produce delays that compromise the operation of events such as transmitting a packet or completing a computation, possibly invalidating the performance evaluation of a network emulation. To address these problems, this paper presents vSDNEmul, a network emulator based on Docker container virtualization. Different from Mininet, vSDNEmul isolates each node in a container and interconnects the nodes through virtual or tunnel links. By using containers, vSDNEmul allows autonomous and flexible creation of independent network elements, resulting in more realistic emulations. This paper reports performance evaluations comparing vSDNEmul and Mininet. The results obtained with the vSDNEmul emulator are more realistic and present higher accuracy.

This work describes a workflow-based environment that manages the execution of software-testing processes. Testing processes require that human and computer resources be handled as dedicated resources, previously scheduled for testing activities, with no overlapping. Two striking features of this environment are: a) the efficient handling of resources by taking into account the capabilities offered by resources required by testing activities, and b) it provides a broader view of all execution steps in a software-testing plan. Hence, it enables a better planning of software-testing process executions, as well as of human and computer resources involved.

The added value of the information transmitted in a cybernetic environment has resulted in a sophisticated malicious actions scenario aimed at data exfiltration. In situations with advanced actors, like APTs, such actions use obfuscation techniques of harmful activities as persistence assurance on strategic targets. The MADEX and NERD architectures proposed flow analysis solutions to detect rootkits that hide network traffic;however, it presents some operational cost, either in traffic volume or due to lack of aggregated information. In that regard, this work changes and improves user flow analysis techniques to eliminate impacts on network traffic, with data enrichment on local and remote bases, detection of domains consulted by rootkits and aggregation of information to generate threat intelligence, while maintaining high performance. The results show the possibility of aggregating information to data flows used by rootkits in order to have effective cyber defense actions against cybernetic threats without major impacts on the existing network infrastructure. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The application of information technology in addition to making internal business processes more effective and efficient, is also to improve customer service. This role is important for companies to maintain the sustainability of information systems as a strategic tool for competitive advantage so system availability is absolutely essential. Research related to the Disaster Recovery Plan (DRP) needs to be carried out to see the readiness of a corporation to build a backup system in different places and locations. By using the method of factor analysis and regression analysis to form an evaluation model, it will obtain an overview of what factors must be considered and what the current conditions are. The results of the study show that there are Core Technical DRP, Organizational Preparation, and Costing factors which are the main variables in supporting DRP readiness. The conclusion from this study, through these three new factors a mathematical model can be built as a reference for improving DRP implementation in corporations. © 2023 The Authors.

Cloud computing has been a great ally in the development of products and services with highly scalable, flexible, on-demand, providing big data to users in different administrative domains services. In this context, federated identity management assist in the administration of access to services and privacy of Personally Identifiable Information (PII). The cloud may impose some security issues, especially some threats to sensitive data such as PII. Therefore, we present a model that addresses privacy issues of PII, considering aspects of dynamic federations, different policies, data manipulation rules and encryption. A prototype of the federation agreement, dynamic scopes and security policies was developed using OpenID Connect (OIDC).

The need for procedures and methodologies used in clinical information standardization is continuous, requiring the current telemedicine networks to evolve and adapt by using mature standards and guidelines as the basis for clinical documents transmitted through the network. In this work, we present a different approach for large-scale use of DICOM SR in telemedicine networks using structured vocabularies as its foundation, resulting in a reliable, efficient and data mining ready application applied in a real world telemedicine network. This approach is applied in a large-scale network where 60 physicians report daily an average of 400 reports; resulting in more than 80,000 reports written and stored in the last nine months. We conclude that the use of this approach can reduce eventual syntax or conceptual mistakes by using proper structured vocabularies in addition to DICOM SR.

Technology will continue to be an important thing in life, technological developments can be found in everyday life. In medical intelligence technology, to identify bio-Terrorism actions, and aspects that can threaten national security, such as targets that may be the object of attack, identify indicators early, build biosecurity, and analyze pathogen communities. The threat that hit the world is when resources are used by irresponsible people or groups and are used as biological weapons (bioweapons), bioterrorism, and others. These biological weapons are not only used for war but can also be used for terrorism purposes. The involvement of biological weapons in the history of war has been used, various weapons were created before the 20th century biological weapons in the form of biological toxins or bacteria from decaying animals and plants, after the 20th-century weapons switched to bacteria (anthrax), viruses (smallpox), and poison (botulinum). Regarding what is used as a biological weapon, this is regulated by various policies, both national policies, and defense policies. Anticipatory steps and efforts to overcome the threat of bioterrorism need to involve all parties, including the community, security forces, health workers, and scientists. Legal reforms can be carried out to perfect and complement existing legal loopholes as a result of controlling bioterrorism which widens the opportunities or loopholes for bioterrorism attacks in Indonesia that should receive state attention and formulate bioterrorism regulations. © 2022 IEEE.
