Superando os riscos da segurança baseada em perímetro - Uma abordagem com identificação federada através de certificados digitais A3/ICP-Brasil e SAML

The traditional perimeter-based approach for computer network security (the castle and the moat model) hinders the progress of enterprise systems and promotes, both in administrators and users, the delusion that systems are protected. To deal with the new range of threats, a new data-safety oriented paradigm, called de-perimeterisation , began to be studied in the last decade. One of the requirements for the implementation of the de-perimeterised model of security is the definition of a safe and effective mechanism for federated identity. This work seeks to fill this gap by presenting the specification, modelling and implementation of a mechanism for federated identity, based on the combination of SAML and X.509 digital certificates stored in smart-cards, following the A3 standard of ICP-Brasil (Brazilian official certificate authority and PKI)

Preferência alimentar e aspectos biológicos de Leptoglossus zonatus Dallas,1852 (Hemiptera: Coreidae) em diferentes genótipos de milho

The present research was accomplished under field and laboratory conditions (T= 25[plus or minus]2[degree] C, R.H.= 70[plus or minus] 10 % and fotoperiod= 12 horas) at FCA/UNICASTELO from Fernandopolis-SP, Brazil. The feeding preference of corn bug Leptoglossus zonatus Dallas, 1852 (Hemiptera: Coreidae) was evaluated on corn genotypes AL-Bianco, AL-Manduri, AL-25 Piratininga, AL-34 e AL-Manduri in the field. Besides, some behavioral factors relative to infestation and oviposition were observed. In laboratory, the nymph's development was evaluated on ears from each corn genotype, aiming to verify the non-preference and/or antibiosis ocurrence. The females of L. zonatus preferred to oviposite on sheats from leaves. Adults and nymphs may occur in whole parts of the plants. The AL-25, AL-34, AL-Manduri and AL-Bandeirante corn genotypes were classified as moderately resistant, expressing non-preference and/or antibiosis against the corn bug. In other way AL-Bianco was the most suscetible to nymphs of the insect.

Seletividade alimentar e influência da idade da folha de Eucalyptus SPP. para Thyrinteina Arnobia (Lepidoptera: Geometridae)

Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae) é considerada uma das mais sérias pragas do eucalipto no Brasil. Este trabalho foi realizado com o objetivo de estudar a preferência alimentar de T. arnobia em seis espécies de eucalipto e a influência da idade foliar sobre a seleção hospedeira, utilizando-se folhas jovens e velhas de Eucalyptus grandis, Eucalyptus camaldulensis, Eucalyptus saligna, Eucalyptus citriodora, Eucalyptus robusta e Eucalyptus cloeziana. Lagartas de T. arnobia alimentadas na geração anterior com folhas de E. grandis preferiram folhas jovens de E. grandis e E.cloeziana, enquanto as alimentadas com E. saligna, na geração anterior, preferiram folhas velhas de E. grandis. A espécie preferida por lagartas de T. arnobia foi E. grandis, observando-se, também maior preferência por folhas jovens que por folhas velhas nas espécies utilizadas nos testes.

Estratégias para elaboração de um plano de segurança da água para abastecimento humano do município do Natal/RN

This research study deals with the production and distribution of drinking water with quality and safety in order to meet the needs of the Man. Points out the limitations of the methodology for assessing water quality in use today. Approaches the recommendations of the World Health Organization (WHO) for adoption, by the companies responsible for producing and distributing water, of assessment methodologies and risk management (HACCP), in order to ensure the quality and safety of water drinking. Suggests strategies for implementing the plan for water safety plan. Uses the process of water production, composed by Maxaranguape river basin, the water treatment plant and distribution system, which is part of the Plan for Expansion of the Supply System of Natal, as case study. The results, it was possible to devise strategies for implementation of the Water Safety Plan (WSP), which comprises the following steps: a) a preliminary stage. b) assessment system. c) process monitoring. d) management plan and e) validation and verification of the PSA. At each stage are included actions for its implementation. The implementation of the PSA shows a new type of water production, in which the fountain as a whole (watershed and point of capture), the Water Treatment Plant (WTP) and distribution, shall compose the production process, over which to build quality and safety of the final product (drinking water)
