Dai log attraverso Logstash e Elasticsearch a Kibana
Per migliorare la visualizzazione dei log raccolti da NetEye abbiamo integrato tre progetti open source: Logstash, Elasticsearch e Kibana.
Logstash legge ed analizza i log raccolti da NetEye e li trasmette ad Elasticsearch (una full-text search engine basata su Lucene che mette a disposizione un’interfaccia web RESTful e documenti schema-free JSON) che li salva come dati strutturati. Dopo questo processo di raccolta, Kibana illustra i dati raccolti all’interno del modulo Syslog View di NetEye.
Con Logstash e Elasticsearch e’ possibile visualizzare i log in tempo reale, in questo esempio possiamo notare un utente ‘pb00170’ che effettua dei LOGON tramite il DC:
logs in tempo reale
Grazie a Kibana3 tutti gli utenti NetEye hanno la possibilità di creare dei cruscotti personalizzati per visualizzare i dati aggregati con diversi modi di rappresentazione.

L’esempio sottostante mostra un cruscotto che visualizza il numero di utenti che hanno eseguito programmi MS Office attraverso Citrix. (Questo può essere utile per decidere quante licenze sono effettivamente necessarie.)
Esempio: accessi via Citrix
Un esempio ulteriore e’ il seguente cruscotto che mostra le statistiche riguardanti gli accessi ai siti web sul webserver locale.
Hi folks!
I began loving computer since 1994, it was still the time of windows 3.1. Immediately I learned starting DOS games from the command promt, and while typing some white text on black background I felt like some hackish dude in a hollywoodian movie.
Later during the studies at the university, I discovered the magic world of opensource, and it was love at first sight. Finally I got rid of BSOD's =)
I love everything that is connected to some network, especially in a security perspective.
My motto is:
"With motivation, nothing is impossibile. It only requires more time."
