Open Source BSD Network Monitoring Software

OSSIM, AlienVault’s Open Source Security Information and Event Management (SIEM) product, provides event collection, normalization and correlation. For more advanced functionality, AlienVault Unified Security Management (USM) builds on OSSIM with these additional capabilities: * Log management * Advanced threat detection with a continuously updated library of pre-built correlation rules * Actionable threat intelligence updates from AlienVault Labs Security Research Team * Rich analytics dashboards and data visualization

Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

Netdisco is an SNMP-based L2/L3 network management tool designed for moderate to large networks. Routers and switches are polled to log IP and MAC addresses and map them to switch ports. Automatic L2 network topology discovery, display, and inventory.

BASE is the Basic Analysis and Security Engine. It is based on the code from the Analysis Console for Intrusion Databases (ACID) project. This application provides a web front-end to query and analyze the alerts coming from a SNORT IDS system.

SSHGuard protects hosts from brute-force attacks against SSH and other services. It aggregates system logs and blocks repeat offenders using several firewall backends, including iptables, ipfw, and pf.

jpcap is a set of Java classes which provide an interface and system for network packet capture. A protocol library and tool for visualizing network traffic is included. jpcap utilizes libpcap, a widely deployed system library for packet capture.

The Nemesis Project is designed to be a command line based, portable human IP stack for UNIX-like and Windows systems. The suite is broken down by protocol, and should allow for useful scripting of injected packets from simple shell scripts.

This module provides attack surface reduction enhancements against the HTTP Flood Attacks at the web application level. Massive crawling/scanning tools, HTTP Flood tools can be detected and blocked by this module via htaccess, firewall or iptables, etc. (like mod_evasive) You can use this module by including "iosec.php" to any PHP file which wants to be protected. You can test module here: http://www.iosec.org/test.php (demo) Watch the Proof of Concept video: http://goo.gl/dSiAL Hakin9 IT Security Magazine Article about IOSEC http://goo.gl/aQM4Di (different format -> http://goo.gl/JKMUPN) IJNSA Article at http://goo.gl/LLxRdX WP Plugin Page http://goo.gl/nF5nD CHANGES v.1.8.2 - Iptables Auto Ban Bash Script Included - Token Access via Implicit Deny - Reverse Proxy Support - reCAPTCHA Support Do you want more features?

Libnids - NIDS E-component, based on Linux kernel. This library provides IP defragmentation, TCP reassembly and port scan detection.

The Network Tracking Database (NetDB for short) tracks all changes to the MAC address tables on your switches and the ARP tables on your routers over time stored in MySQL. It supports extensive switch, VLAN and vendor code reports from a CLI or Web App. NetDB can generate CSV reports, track the usage of static IP addresses, record neighbor discovery data and much more. There is now a VM "appliance" with easier upgrades available in the Files section. See the http://netdbtracking.sourceforge.net for more details.

ngrep strives to provide most of GNU grep's common features,applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular expressions to match against data payloads of packets. SUPPORT/REPORTING BUGS: please use https://github.com/jpr5/ngrep/issues Thank you!

phpLDAPadmin is a web-based LDAP administration tool for managing your LDAP server. With it you can browse your LDAP tree, view LDAP schema, perform searches, create, delete, copy and edit LDAP entries. You can even copy entries between servers.

tcpick is a textmode sniffer; it tracks tcp streams, shows the status, reassembles and saves the data captured in files or displays them in the terminal in different modes (ascii, hex..). There is a color-mode. Useful to get files passively.

NOTE: Project has moved to github, including file downloads. SharpPcap is a cross-platform packet capture framework for the .NET environment, based on the famous pcap / WinPcap libraries. It provides an API for capturing, injecting, analyzing and building packets using any .NET language such as C# and VB.NET.

Output spool reader for Snort! This program decouples output overhead from the Snort network intrusion detection system and allows Snort to run at full speed. It takes input and output plugins and can therefore be used to convert almost any spooled fil

Simple Event Correlator (SEC) is a lightweight event correlator for network management, log file monitoring, security management, fraud detection, and other tasks which involve event correlation.

** As of Snort 2.9.7.6, we are longer releasing Snort on SourceForge. Please head to http://www.snort.org from now on!** **As of June 2017, the mailing lists are no longer on SourceForge, and have moved to https://lists.snort.org** Snort is a libpcap-based sniffer/logger which can be used as a network intrusion detection and prevention system. It uses a rule-based detection language as well as various other detection mechanisms and is highly extensible.

Knocker is a simple, versatile, and easy-to-use TCP security port scanner written in C, using threads. It is able to analyze hosts and the network services which are running on them. It is available for Linux, FreeBSD, Unix, and Windows95/98/2000.

Active dictionary attack on WEP keys in WLAN networks.

Nast is a packet sniffer and a LAN analyzer. It sniff packets and save data in files, checks NIC in promisc mode,build LAN hosts list, find a gw,performs a port scanning, catchs daemon banner etc... It also provides a GTK/ncurses interface.

netleak is a collection of small perlscripts that detects connectivity between network segments. It is mostly useful to detect "leaks" in large organizations that have private network segments physically separated from the Internet.

PADS is a signature based detection engine used to passively detect network assets. It is designed to complement IDS technology by providing context to IDS alerts.

The Neighbor Discovery Protocol Monitor (NDPMon) is used by Internet Protocol version 6 network administrators for monitoring ICMPv6 packets. NDPMon observes the local network for anomalies in the function of nodes using Neighbor Discovery Protocol (NDP) messages, especially during the Stateless Address Autoconfiguration. When an NDP message is flagged, it notifies the administrator by writing to the syslog or by sending an email report. It may also execute a user-defined script. For IPv6, NDPMon is an equivalent of Arpwatch for IPv4, and has similar basic features with added attacks detection. NDPMon also maintains up-to-date a list of neighbors on the link and watches all advertisements and changes. It permits to track the usage of cryptographically generated interface identifiers or temporary global addresses when Privacy extensions are enable (default behavior in Ubuntu and Windows for example).

Psniff is a packet sniffer and spoofer based on the PF_PACKET protocol family provided in kernel >=2.0 . Some of the protocols initially supported are IPV4,IPV6,TCP,UCP,BGP,ICMP,RIP, NTP.
