ns4 is a command line configuration management tool that runs on a Unix or Windows based operating system. It allows the automated backup of node (i.e. routers and switches) configurations to an FTP/SFTP server or local media on a daily basis to create configuration archives. It can run ad-hoc commands on multiple nodes as well as custom scripts for automating complex tasks. It uses Perl and allows you to manipulate the output of commands using regular expressions within scripts. Configuration based cartridges are used to specify new node types, allowing the user to extend its functionality in a simple and dynamic way.
A 'honeypot' is designed to detect server-side attacks. In contrast, a 'honeyclient' is designed to detect client-side attacks. Specifically, a honeyclient is a dedicated host that drives specially instrumented applications to access remote servers to see if those servers are behaving in a malicious manner (by compromising the client). Honeyclients can proactively detect exploits against client applications without known signatures. This framework uses a client-server model with SOAP messaging as the primary communication method, and uses the free version of VMware Server as a means of virtualizing the client environment.
check_writable is a Nagios plugin that checks if one or more directories are writable by checking that the supplied directory is indeed a directory, checking if the the filesystem permissions are OK, creating a temporary file, writing random data to the temporary file, and reading it back. It returns a critical status if one of the tests fails.
Reliable Response Notification provides guaranteed delivery of critical messages to a wide range of devices. It guarantees that every emergency will have one, and only one, person responding and taking charge of the recovery. For integrated services, like some network monitors, help-desk packages, and security suites, Reliable Response Notification allows the user to update records via their mobile devices. It is available as either a standalone server or as a hosted service.
Keywatch is a free, OSGi-based monitoring system that provides the adaptability of a modern monitoring system without being complex or hard to configure.

SkipoleMonitor is a free network monitor. On running the program, a GUI window appears, and hosts can be added, which Skipole Monitor will regularly ping, showing Red-Yellow-Green status results via a built-in Web server. Email and syslog alerts can be generated as hosts change status.
