Abstract(s)
Os estudos mais recentes identificam as áreas portuárias como um alvo provável de
atividade terrorista, não só devido à importância que representam para o comércio
mundial mas pela dificuldade em monitorizar e responder em tempo útil a qualquer
ameaça com origem na superfície aquática. O grupo de trabalho DAT-POW, da NATO,
através do seu projeto SAFE-PORT tem como objetivo a criação de um simulador que
auxilie na implementação de dispositivos de defesa portuária. Neste sentido, pretende-se
reduzir a susceptibilidade das infraestruturas portuárias em sofrerem um ataque
terrorista que afecte o normal funcionamento da mesma.
Assim, o projecto SAFE-PORT compreende um módulo de ameaças, na qual esta
dissertação se insere, cujo propósito é simular o comportamento de agentes terroristas
durante o seu ataque à infraestrutura portuária. Da análise da reacção do dispositivo
defensivo, perante esta ameaça, é esperada a capacidade de identificar lacunas no
mesmo, potenciando a redução da taxa de sucesso dos ataques subsequentes através de
uma optimização do sistema de defesa existente.
O módulo de ameaças é constituído por diferentes agentes, responsáveis por executarem
ataques de superfície e sub-superfície.
O presente trabalho comporta a criação de um modelo comportamental de agentes
inteligentes, responsáveis por ataques de sub-superfície. Face à inexistência de
incidentes em que tenham sido identificados este tipo de agentes, a criação dos modelos
supramencionados depende de um conhecimento da dinâmica própria de acções de
mergulho, assim como de técnicas de reprodução desse comportamento num ambiente
computacional. Deste modo, a modelação comportamental destes agentes apresenta:
uma análise morfológica do terrorista, por forma a facilitar o estabelecimento de
pressupostos necessários à elaboração dos perfis; uma proposta de perfil de ataque
criado a partir do modelo de máquinas de estado híbridas; o planeamento de um
exercício real de obtenção de dados, que permita a otimização dos perfis de ataque
propostos.
Recent studies identify the port areas as a likely target of terrorist activity, not only because of the importance they pose to the world trade but also because of the difficulty to monitor and respond in timely fashion to any threat originating from water surface. The workgroup DAT-POW through the project SAFE-PORT aims to create a simulator to assist in the implementation of harbour defence systems. In this sense, the intention is to reduce the susceptibility of port infrastructure in suffering a terrorist attack that affects the normal functioning of the same. The project SAFE-PORT comprises a threats module whose purpose is to simulate the behaviour of agents during the terrorist attack on its infrastructure. The analysis of how the system reacts to threats, is expected contribute to identify gaps on it, empowering the reduction of the success rate of subsequent attacks by optimizing the existing defence system. The threat module is constituted by different agents responsible for executing surface and sub-surface attacks. This work involves the creation of a behavioural model of intelligent agents, responsible for sub-surface attacks. In the absence of incidents on which have been identified such agents, the creation of the models mentioned above depends on a knowledge of the dynamics of diving actions as well as techniques of reproducing this behaviour in a computer environment. Therefore, the behaviour modelling of these agents presents: A morphological analysis of the terrorist in order to facilitate the establishment of assumptions necessary for the preparation of the profiles; a proposed attack profile created from the hybrid state machine model; the planning a real data collection exercise, enabling the optimization of the proposed attack profiles.
