Background: SNMP is the Simple Network Management Protocol. It is used by many if not most companies to manage and monitor their infrastructure. It is also often overlooked in terms of security and underestimated as an attack vector. RFC1157. Components: The program is a GUI program, written in c#, so you'll need the .NET framework (3.5) and it will only work in MS Windows (Mono and Windows GUI components are a pain to make compatible for now). It uses 2 DLL's that were written from scratch: the hacking.snmp and hacking.bruteforce.dll. The SNMP dll is not complete yet but whenever the author finds time it will be extended to support bulkget and extended ASN parsing, so enumeration will become possible as well as SET actions. You will also need to provide a dictionary for dictionary attacks. A very small one is included. Generic usage: The interface should be intuitive enough. Use the slider to increase or decrease scanning speed. This is important to get accurate results. On a LAN the slider can be set to maximum speed. Behind a Natted broadband connection, caution is advised. Devices such as ADSL modems aren't capable to deal with the large amount of packets and nat connections they generate. The program uses non-blocking udp sockets and a listener for answers, which makes it quite fast. You can also set the destination port for devices which listen on non-standard ports (not 161) and set the listening port to make sure the packets get back ok in case of firewalls. For optimal speed, turn off verbosity, errors and reverse lookups (only in case of maximum speed on a LAN). Results can be saved in XML for further processing and loaded back.
Lan-Secure Switch Center
Switch Center is network management software for managed network switches and hubs from any vendor supporting SNMP BRIDGE-MIB that helps to discover, monitor and analyze networks connectivity and performance. Switch Center can be connected through any network port without the need of remote agents or special network configuration. The unique monitoring engine provides complete network connectivity and performance of local and remote network nodes and interconnecting switch trunks. The software supports SNMPv1/2 and SNMPv3 discovery options including Ten Giga switch ports. The built-in central viewer supports multiple management levels and provides automatic network mapping using OSI Layer 2 and Layer 3 topology including real-time reports, statistics and alerts. Switch Center key features: Real-time network discovery and monitoring. Nodes and users discovery including port location. Multi vendors network switch ports mapper and scanner. Real-time network connectivity supporting graphical views. Real-time reports and statistics including exporting capabilities. Database exporting capability supporting SQL and HTML for online updating. Central viewer supporting multiple levels of management users and access permissions. Ten Giga switch ports scanning and monitoring. Support SNMPv1/2 and SNMPv3 scanning. Email and SNMP trap alerts forwarding. Daily and weekly e-mail reports.
Pandora FMS is monitoring software. It can detect a network interface down, a defacement in your website, a memory leak in one of your server application, or the movement of any value of the NASDAQ new technology market. Pandora FMS can send SMS messages when your systems fails... or when Google's value drop below US$ 500. Pandora FMS can monitor Windows remotely (through WMI), any device via TCP and/or ICMP checks, and any SNMP device through polling and trap reception. Also allows to reuse user-defined "plugins" that make remote checks, like execute remote commands, connecting devices by telnet to gather data, etc. Pandora FMS can perform periodical network reconnissances to discover new hosts and devices on the network and can create a visual network map, with its network topology and OS type. Pandora FMS also has an WYSIWYG AJAX Visual Console editor for interactive map creation; It has also advanced features like data replication across multiple Pandora FMS setups, pattern-anomaly detection, a prediction engine, a event notificacion manager and a correlation alert system. Besides agentless monitoring it has software agents that can be installed in most OS on the market, these agents can be remotely configured from the Console, and are able to process logs from Windows and Unix systems. Reporting features include user defined reports: SLA checks, real time graphs, and much more possibilities thanks to its SQL automanaged backend. Link & Other data:

ASDIC is a system for advanced traffic and log analysis. It helps you to determine what traffic there is in your network. You can look at ASDIC as a reverse firewall. Input unstructured traffic information and output a rule set. ASDIC can analyze logs from any firewall or router, or sniff the network by itself.
