Foi lan\u00e7ado o sistema de an\u00e1lise de tr\u00e1fego e detec\u00e7\u00e3o de intrus\u00f5es Zeek 8.0.0, anteriormente conhecido como Bro. O Zeek \u00e9 uma plataforma de an\u00e1lise de tr\u00e1fego focada principalmente no monitoramento de eventos relacionados \u00e0 seguran\u00e7a, mas que n\u00e3o se limita a esse uso. O c\u00f3digo do sistema \u00e9 escrito em C++ e \u00e9 distribu\u00eddo sob a licen\u00e7a BSD. <\/p>\n
A plataforma oferece m\u00f3dulos para an\u00e1lise e disseca\u00e7\u00e3o de v\u00e1rios protocolos de rede de n\u00edvel de aplica\u00e7\u00e3o, considerando o estado das conex\u00f5es e permitindo a forma\u00e7\u00e3o de um registro detalhado (arquivo) da atividade de rede. \u00c9 fornecida uma linguagem orientada a dom\u00ednio para escrever scripts de monitoramento e detec\u00e7\u00e3o de anomalias, levando em conta as especificidades de infraestruturas concretas. O sistema \u00e9 otimizado para uso em redes de alta capacidade. Uma API \u00e9 oferecida para integra\u00e7\u00e3o com sistemas de informa\u00e7\u00e3o externos e troca de dados em tempo real. <\/p>\n
Na nova vers\u00e3o do Zeek: <\/p>\n
Al\u00e9m disso, cabe destacar o lan\u00e7amento do scanner de seguran\u00e7a de rede Nmap 7.98, destinado \u00e0 auditoria de rede e identifica\u00e7\u00e3o de servi\u00e7os de rede ativos. O c\u00f3digo do projeto \u00e9 fornecido sob a licen\u00e7a NPSL (Nmap Public Source License), baseada na licen\u00e7a GPLv2, que \u00e9 complementada por recomenda\u00e7\u00f5es (n\u00e3o exig\u00eancias) sobre o uso do programa com licenciamento OEM e a compra de uma licen\u00e7a comercial, caso o fabricante n\u00e3o deseje abrir o c\u00f3digo de seu produto de acordo com os requisitos da licen\u00e7a copyleft ou pretenda integrar o Nmap em produtos incompat\u00edveis com a GPL. <\/p>\n
Na vers\u00e3o Nmap 7.98, est\u00e3o principalmente presentes corre\u00e7\u00f5es de erros. Por exemplo, foram eliminadas falhas que ocorriam ao usar o nmap com alguns VPN<\/a>-interfaces. Entre as mudan\u00e7as funcionais, destaca-se a adi\u00e7\u00e3o de bindings NSE para uso de fun\u00e7\u00f5es libssh2 em scripts de automa\u00e7\u00e3o de a\u00e7\u00f5es com Nmap. O funcionamento do resolvedor DNS foi otimizado. Adicionou-se suporte a cifras utilizadas no TLSv1.3 na biblioteca tls.lua, incluindo conjuntos de cifras p\u00f3s-qu\u00e2nticos. As vers\u00f5es do OpenSSL 3.0.17, Lua 5.4.8 e Npcap 1.83, utilizadas nas compila\u00e7\u00f5es prontas, foram atualizadas. \u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u0441\u0438\u0441\u0442\u0435\u043c\u044b \u0430\u043d\u0430\u043b\u0438\u0437\u0430 \u0442\u0440\u0430\u0444\u0438\u043a\u0430 \u0438 \u0432\u044b\u044f\u0432\u043b\u0435\u043d\u0438\u044f \u0441\u0435\u0442\u0435\u0432\u044b\u0445 \u0432\u0442\u043e\u0440\u0436\u0435\u043d\u0438\u0439 Zeek 8.0.0, \u0440\u0430\u043d\u0435\u0435 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0432\u0448\u0435\u0439\u0441\u044f \u043f\u043e\u0434 \u0438\u043c\u0435\u043d\u0435\u043c Bro.
