TinyIDS is a distributed intrusion detection system (IDS) for Unix systems. It is based on the client/server architecture and has been developed with security in mind. The client, tinyids, collects information from the local system by running its collector backends. The collected information may include anything, from file contents to file metadata or even the output of system commands. The client passes all this data through a hashing algorithm and a unique checksum (hash) is calculated. This hash is then sent to one or more TinyIDS servers (tinyidsd), where it is compared with a hash that had previously been stored in the databases of those remote servers for this specific client. A response indicating the result of the hash comparison is finally sent back to the client. Management of the remotely stored hash is possible through the client's command line interface. Communication between the client and the server can be encrypted using RSA public key infrastructure (PKI).
SysScope is a graphing solution that facilitates the visual representation of RRDtool's Round Robin Databases (RRD). It retrieves the graph options from an Apache-style configuration file and, after making the necessary calls to rrdgraph, it generates static or dynamic HTML pages containing the graphs. The following backends are supported for the generation of the dynamic pages: CGI, FastCGI, mod_python, and WSGI.
