What's new in Snort

  • New additions:
  • Application Identification Preprocessor, when used in conjunction with open app ID detector content, that will identify application protocol, client, server, and web applications (including those using SSL) and include the info in Snort alert data. In addition, a new rule option keyword 'appid' that can be used to constrain Snort rules based on one or more applications that are identified for the connection. See README.appid for details.
  • A new protected_content rule option that is used to match against a content that is hashed. It can be used to obscure the full context of the rule from the administrator.
  • Protocol Aware Flushing (PAF) improvements for SMTP, POP, and IMAP to more accurately process different portions of email messages and file attachments.

3 Snort Screenshots:
Snort is a Mac OS X command line tool that brings a network intrusion prevention system to your computer. The utility will analyze your traffic in real time in order to help you view what protocols are used, or possible outside attacks, probes, scans, and so on.

Network intrusion prevention system that must be compiled from source

Snort is not available as a binary distribution, and does not come with a graphical user interface: you will download the source code archive, and you will have to manually compile it via the Terminal app. Note that you must also have the Xcode Command Line Tools deployed on your Mac.

To install Snort, you must go to the Snort folder in a new Terminal window (drag and drop the Snort folder on top of the Terminal Dock icon) and run the following commands: “./configure”, “make”, “sudo make install”, and “snort”.

Take into consideration that certain command take longer to complete than others, and that you might also need to install certain dependencies (including the daq library that can be downloaded from the Snort project page).

Monitor or protect your network via the command line

The Snort application can either track your network’s traffic (sniffer mode) and log all the transferred packages (packet logger mode), or act like a prevention system and detect potentially unwanted intrusions.

To help you get started, the Snort developers provide an extensive user manual that presents all the included functions and possible uses, configurations details, and so on. The application includes various monitoring, logging, and alerting tools, so reading the documentation is highly recommended.

To conclude, if you are looking for an unobtrusive yet powerful tool that can log your network traffic and detect potentially harmful intrusions, the Snort open source network intrusion prevention system certainly deserves your attention.
