Table of Contents Introduction Ntopng Features Requirements Installing Ntopng Start the Ntopng and Redis Service Configure Ntopng Allow Ntopng Through the Firewall Test Ntopng Introduction Ntopng is an opensource network traffic monitoring system that provides a web interface for real-time network monitoring. It very useful tool that helps you learn more about your network traffic. Ntopng provides several tools for monitoring various protocols, traffic variants and bandwidth across multiple time frames. You can install ntopng on any monitoring server connected to your network and use a web browser to access real-time traffic reports available on the server. In this tutorial, I will explain how to set up a web-based network traffic monitoring system on CentOS 7 using ntopng. Ntopng Features Protocol-level real-time analysis of local network traffic. Geolocation of IP addresses. Network traffic matrix Historical traffic analysis Support for sFlow, NetFlow...

Prerequisites To get the most from the article, you should have a basic knowledge of SNORT, Linux and a working Linux system on which you can practice the commands covered in this article. Also you should have some networking knowledge such as TCP/IP, iptables, etc. What Is IPS (Intrusion Prevention System)? Intrusion Detection System (IDS) is a device which monitors packets on your network. IDS reports attack behaviors based on security rules and signatures applied on the device. However IDS has certain disadvantages, such as high false positive rate, unable to stop Denial of Service (DoS) attack and intrusion from UDP protocols. Intrusion Prevention System (IPS), on the other hand, not only has the ability of IDS, but also can drop malicious packets and close connection sessions in order to stop further attacks. IPS could achieve Real-time Interdiction by leveraging in-line deployment in the network topology. It analyzes all network traffic passing through syst...

Snorby is a ruby on rails web application for network security monitoring that interfaces with current popular intrusion detection systems (Snort, Suricata and Sagan). The basic fundamental concepts behind Snorby are simplicity, organization and power. The project goal is to create a free, open source and highly competitive application for network monitoring for both private and enterprise use. Set up your system with the follow script to ensure that nothing will be missing http://wiki.douglasqsantos.com.br/doku.php/confinicialcentos7_en The Snorby will use the follow ip: 192.168.1.251 Let's install the development tools yum groupinstall "Development Tools" -y Let's install the dependencies for Snorby. yum install openssl-devel readline-devel libxml2-devel libxslt-devel mariadb mariadb-devel mariadb-server urw-fonts libX11-devel libXext-devel git \ fontconfig-devel libXrender-devel unzip wget xorg-x11-server-Xvfb libyaml libyaml-devel gdbm-de...

This post is about how to install Snort "stack" on CentOS7 with potentially all the latest libs an stuff. Here I will install and configure everything to run Snort as IDS. I will write another post shortly how to run it as IPS - INLINE.

This bridge network allows virtual machines to have access to the external network and vice-versa, follow this guide to setup network bridge on CentOS 7 / RHEL 7. Install Module: CentOS 7 comes with bridging module loaded on system boot by default, verify it by using below command.  #modinfo bridge filename:       /lib/modules/3.10.0-327.el7.x86_64/kernel/net/bridge/bridge.ko alias:          rtnl-link-bridge version:  ...

Nesses dias, na seção de trabalho, recebi um Tablet da Samsung que depois reiniciar não saia da palavra "SAMSUNG". Várias soluções me vieram a cabeça, mas aí pensei: "O android também é Linux, então dever ter algo que posso fazer para consertar isso!"   Dito e feito, lembrei de um procedimento que usava com todos os Tablets desta marca. O famigerado "Hard Reset". Como haviam me informado que não precisava me preocupar com os dados do Tablet, procedi da seguinte maneira: 1. Desligar o TABLET 2.  Pressione simultaneamente os Botões  Volume Acima + Ligar 3.  Quando aparelho começar a ligar, liberar apenas o  Botão ligar 4.  Selecione  wipe/data factory reset  e confirme com  Ligar 5.  Escolha  Yes — delete all user data  e confirme com  Ligar 6.  Escolha  reboot system now  e confirme com  Ligar O TABLET demorou para reiniciar, mas voltou a funcionar. O único problema é que t...
