A former head of German counter-intelligence recently confided: "The best piece of intelligence is the one that only I possess." That spymaster's emphasis on exclusivity and withholding information even from his friends is, alas, the watchword among intelligence chiefs worldwide. And it threatens to undermine efforts to globalize the hunt for terrorists and their bad works.

Timely and credible intelligence - often the merest scrap - can be as decisive in foiling¹ terrorist plotting as any police action, cruise missile, or bomb. That's why the American Congress and the White House are focused on improving information sharing between the CIA and FBI. But the debate has so far overlooked another chronic intelligence failure: the inadequacy of the CIA's liaison with other intelligence services.

One reason for urgent reform is that even though the United States far outstrips other countries in its technical intelligence gathering, many other nations often have better human intelligence, or humint - real live spies.

¹foil - to prevent (someone or something) from being successful.

O programa tcpwrapper permite controlar conexões TCP para servidores cujos serviços são inicializados pelo programa inted em sistemas Unix. Esse programa pode realizar verificações de endereços IP, de entradas em DNS e de nomes de hospedeiros, sendo capaz também de registrar eventos e executar comandos de proteção e de reação a ataques.

As redes locais fast-ethernet conservam o protocolo CSMA/CD e o formato do quadro ethernet, mas reduzem a duração dos bits de 100 nanossegundos para 10 nanossegundos.

Com base em tabelas de comutação construídas manualmente pelos administradores das redes locais ethernet comutadas, os comutadores ethernet (switches) realizam filtragem e repasse de quadros ethernet com base na análise dos endereços MAC (medium access control) presentes em tais quadros.

Após ser instalado em memória e inicializar os drives de dispositivos, o kernel do sistema Linux dispara o processo init, que é o primeiro processo de nível usuário e tem a responsabilidade de realizar tarefas administrativas — tais como verificação dos sistemas de arquivos, limpeza do diretório /tmp e inicialização de serviços — e de disparar um processo getty para cada terminal ou console virtual que possa ser utilizado pelos usuários para obter acesso (log on) ao sistema.
