AlienVault Open Source SIEM
AlienVault Open Source SIEM (OSSIM) is a complete Security Management solution that detects and profiles attacks, and provides a comprehensive, intelligent Security Management platform and toolset.
The entire solution is composed of open source distributions including all seamlessly integrated tools, and the security management platform. The OSSIM project was created and is currently coordinated by the founders of AlienVault.
See the OSSIM forge
The OSSIM platform consists of a Management Server, and Sensor or “Probe”. A professional version that includes Logger functionality is also available (please see below). The solution may be implemented as a single monolithic appliance or a set of appliances in which probes are separated from the management server, and distributed throughout the enterprise.
Probes capture network and system information in real time, and send it to the central Management Server where the data is analyzed to assess immediate threats and risk, filter out false positives, and locate false negatives that other security devices and software on the network cannot detect.
Probes not only capture data, but can be tasked as sophisticated attack detection components. They come with several attack detection systems, audit systems, and context learning systems (network profiles, inventory, availability), all of which are seamlessly integrated. When deployed in this fashion probes provide a very quick and safe way of continuously and transparently monitoring local and remote networks, providing provide full visibility of all security related aspects of the enterprise.
The information from the organization’s security systems, such as the firewall, antivirus, IPS, HIDS, etc, are all collected through these probes, and then analyzed through sophisticated intelligence technology. This technology correlates data from many sources to detect blended threats otherwise undetectable by individual systems; prioritize these threats; and make automated decisions with regard to the risk implied in each one.
OSSIM provides a complete management, reporting, and security analysis environment including graphical analysis, incident management workflow, and other tools. This system is capable of monitoring the security of globally distributed networks from a customizable, management console. High level, graphical dashboards are used to progressively drill down to the lowest level of detail.
