Zeek er en platform til trafik analyse, der prim\u00e6rt fokuserer p\u00e5 at overv\u00e5ge sikkerhedsevents, men ikke er begr\u00e6nset til denne anvendelse. Systemets kode er skrevet i C++ og distribueres under BSD-licensen.    <\/p>\n<p>Platformen tilbyder moduler til analyse og parsing af forskellige applikationsprotokoller, der tager h\u00f8jde for forbindelsens tilstand og tillader dannelse af detaljerede logfiler (arkiver) over netv\u00e6rksaktiviteter. Der tilbydes et dom\u00e6nespecifikt sprog til at skrive overv\u00e5gnings- og anomalidetektions scripts, der tager h\u00f8jde for specifikationen af de enkelte infrastrukturer. Systemet er optimeret til brug i netv\u00e6rk med h\u00f8j b\u00e5ndbredde. Der tilbydes en API til integration med tredjeparts informationssystemer og realtidsdataudveksling.    <\/p>\n<p>I den nye udgivelse af Zeek:  <\/p>\n<ul>\n<li class=\"l\"> Muligheden for at konfigurere netv\u00e6rksflow-ID'er (Flow Tuple) via plugins er blevet tilf\u00f8jet. For at undg\u00e5 sammenst\u00f8d ved deling af flows i komplekse netv\u00e6rk kan man nu, ud over <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/lir\/ipv4\/\"   title=\"IP-adresser\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"881\">IP-adresser<\/a>, tage h\u00f8jde for portnumre og protokoller, ogs\u00e5 tage ekstra kontekst i betragtning, s\u00e5som VLAN-tags eller identifikatorer for indkapslet trafik for VXLAN og Geneve.\n<li class=\"l\"> En ny clustered backend baseret p\u00e5 ZeroMQ er klar til brug i produktionssystemer og definerer metoden for interaktion mellem cluster-noder og datserializedataformatet. Broker backenden forts\u00e6tter med at blive anvendt som standard, men i fremtiden er der planlagt en overgang til ZeroMQ backenden som standard, som g\u00f8r det muligt at undg\u00e5 proxies ved distribution af broadcast-beskeder mellem noder. Indsamlingen af telemetri om clusterets arbejde er blevet forenklet, hvilket g\u00f8r det muligt at overv\u00e5ge belastningen p\u00e5 noderne, uanset hvilken backend der anvendes.\n<li class=\"l\"> En parser til Redis databaseprotokollen er blevet tilf\u00f8jet, og logning af opsnappede operationer er blevet sikret.\n<li class=\"l\"> SMTP-analysatoren har implementeret underst\u00f8ttelse til at ekstrahere e-mails (RFC 822) fra trafik og sende dem til filanalysatoren, hvilket kan bruges til at gemme opsnappede e-mails p\u00e5 disk som filer i .eml format.\n<li class=\"l\"> FTP-analyzatoren har f\u00e5et tilf\u00f8jet st\u00f8tte til AUTH TLS-udvidelsen.\n<li class=\"l\"> DNS-analyzatoren har implementeret genkendelse af NAPTR-poster.\n<li class=\"l\"> PPPoE-analyzatoren har f\u00e5et mulighed for at udskrive sessionens identifikatorer.\n<li class=\"l\"> I stedet for separate logfiler analyzer.log og dpd.log anvendes en samlet log analyzer.log.\n<li class=\"l\"> Parser-generatoren til protokoller og filer er blevet opdateret til version Spicy 1.14, som tilbyder nye optimeringer og muligheden for at fjerne ubrugte funktionsparametre.\n<li class=\"l\"> Der er givet mulighed for at \u00e6ndre logformatet ved hj\u00e6lp af pakken logschema (for eksempel kan man bruge JSON eller CSV i stedet for traditionelle tekstlogs).\n<li class=\"l\"> For at bygge projektet kr\u00e6ves nu en compiler, der underst\u00f8tter C++20-standarden. De minimumsunderst\u00f8ttede versioner er angivet som GCC 10, Clang 8 og Visual Studio 2022.      <\/ul>\n<p>Desuden kan vi n\u00e6vne udgivelsen af netv\u00e6rkssikkerhedsscanneren Nmap 7.98, der er designet til at udf\u00f8re netv\u00e6rksrevision og identificere aktive netv\u00e6rkstjenester. Projektkoden leveres under NPSL (Nmap Public Source License), der er baseret p\u00e5 GPLv2-licensen, som er suppleret med anbefalinger (ikke krav) til brug af OEM-licensering og k\u00f8b af kommercielle licenser, hvis producenten ikke \u00f8nsker at \u00e5bne koden til sit produkt i henhold til copyleft-licensens krav eller \u00f8nsker at integrere Nmap i produkter, der ikke er kompatible med GPL.     <\/p>\n<p>I version Nmap 7.98 er der prim\u00e6rt fejlrettelser. For eksempel er der rettet nedbrud ved brug af nmap med visse <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vpn\/\"   title=\"VPN\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"277\">VPN<\/a>-interfaces. Af funktionelle \u00e6ndringer kan fremh\u00e6ves tilf\u00f8jelsen af NSE-bindings til brug af libssh2-funktioner i automatiseringsscripts til Nmap. DNS-opl\u00f8sningen er blevet optimeret. Biblioteket tls.lua har f\u00e5et tilf\u00f8jet st\u00f8tte til cipher suites anvendt i TLSv1.3, inklusive post-kvante cipher suites. Versionerne OpenSSL 3.0.17, Lua 5.4.8 og Npcap 1.83, der anvendes i de f\u00e6rdige builds, er blevet opdateret.<br \/>\n<br \/>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63772\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\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.
