Um lan\u00e7amento est\u00e1vel est\u00e1 previsto para ser publicado dentro de um m\u00eas.<\/p>\n<p>Na ramifica\u00e7\u00e3o do Snort 3, o conceito do produto foi completamente reformulado e a arquitetura foi reestruturada. Entre os principais direcionamentos do desenvolvimento do Snort 3 est\u00e3o: simplifica\u00e7\u00e3o da configura\u00e7\u00e3o e inicializa\u00e7\u00e3o do Snort, automa\u00e7\u00e3o da configura\u00e7\u00e3o, simplifica\u00e7\u00e3o da linguagem de constru\u00e7\u00e3o de regras, detec\u00e7\u00e3o autom\u00e1tica de todos os protocolos, fornecimento de uma interface de gerenciamento via linha de comando, e a aplica\u00e7\u00e3o intensa de multithreading com acesso compartilhado de diferentes manipuladores a uma \u00fanica configura\u00e7\u00e3o. <\/p>\n<p>As seguintes inova\u00e7\u00f5es significativas foram implementadas:<\/p>\n<ul>\n<li class=\"l\"> Uma nova sistema de configura\u00e7\u00e3o foi introduzido, oferecendo uma sintaxe simplificada e permitindo o uso de scripts para a cria\u00e7\u00e3o din\u00e2mica de configura\u00e7\u00f5es. O LuaJIT \u00e9 usado para processar arquivos de configura\u00e7\u00e3o. Plugins baseados em LuaJIT oferecem op\u00e7\u00f5es adicionais para regras e para o sistema de registro;\n<\/li>\n<li class=\"l\"> O mecanismo de detec\u00e7\u00e3o de intrus\u00f5es foi modernizado, as regras foram atualizadas e foi adicionada a capacidade de atachar buffers nas regras (sticky buffers). O mecanismo de busca Hyperscan foi utilizado, permitindo o uso de padr\u00f5es r\u00e1pidos e mais precisos nas regras com base em express\u00f5es regulares;\n<\/li>\n<li class=\"l\"> Um novo modo de introspec\u00e7\u00e3o para HTTP foi adicionado, levando em considera\u00e7\u00e3o o estado da sess\u00e3o e abrangendo 99% das situa\u00e7\u00f5es suportadas pelo conjunto de testes <noindex><a rel=\"nofollow\" href=\"https:\/\/noxxi.de\/research\/http-evader.html\">HTTP Evader<\/a><\/noindex>.

Agora \u00e9 poss\u00edvel o processamento de pacotes em m\u00faltiplas threads, permitindo a execu\u00e7\u00e3o simult\u00e2nea de v\u00e1rias threads com processadores de pacotes e garantindo escalabilidade linear em rela\u00e7\u00e3o ao n\u00famero de n\u00facleos da CPU;\n<\/li>\n<li class=\"l\"> Um reposit\u00f3rio de configura\u00e7\u00e3o e uma tabela de atributos foram implementados, sendo este compartilhado entre diferentes subsistemas, o que reduziu consideravelmente o consumo de mem\u00f3ria ao eliminar a duplica\u00e7\u00e3o de informa\u00e7\u00f5es.\n<\/li>\n<li class=\"l\"> Um novo sistema de registro de eventos que utiliza o formato JSON e \u00e9 facilmente integr\u00e1vel com plataformas externas, como o Elastic Stack;\n<\/li>\n<li class=\"l\"> Transi\u00e7\u00e3o para uma arquitetura modular, com capacidade de expandir a funcionalidade atrav\u00e9s da conex\u00e3o de plugins e implementa\u00e7\u00e3o de subsistemas-chave na forma de plugins substitu\u00edveis. Atualmente, j\u00e1 existem centenas de plugins implementados para o Snort 3 que cobrem v\u00e1rias \u00e1reas de aplica\u00e7\u00e3o, permitindo, por exemplo, adicionar seus pr\u00f3prios codecs, modos de introspec\u00e7\u00e3o, m\u00e9todos de registro, a\u00e7\u00f5es e op\u00e7\u00f5es nas regras;\n<\/li>\n<li class=\"l\"> Detec\u00e7\u00e3o autom\u00e1tica de servi\u00e7os em execu\u00e7\u00e3o, eliminando a necessidade de especificar manualmente as portas de rede ativas.\n<li class=\"l\"> Suporte a arquivos para redefini\u00e7\u00e3o r\u00e1pida das configura\u00e7\u00f5es em rela\u00e7\u00e3o \u00e0 configura\u00e7\u00e3o padr\u00e3o foi adicionado. Para facilitar a configura\u00e7\u00e3o, o uso de snort_config.lua e SNORT_LUA_PATH foi interrompido.<br \/>\nSuporte para recarregar as configura\u00e7\u00f5es em tempo real foi
