A system and method are disclosed for detecting intrusions in a host system on a network. The intrusion detection system comprises an analysis engine configured to use continuations and apply forward- and backward-chaining using rules. Also provided are sensors, which communicate with the analysis engine using a meta-protocol in which the data packet comprises a 4-tuple. A configuration discovery mechanism locates host system files and communicates the locations to the analysis engine. A file processing mechanism matches contents of a deleted file to a directory or filename, and a directory processing mechanism extracts deallocated directory entries from a directory, creating a partial ordering of the entries. A signature checking mechanism computes the signature of a file and compares it to previously computed signatures. A buffer overflow attack detector compares access times of commands and their associated files. The intrusion detection system further includes a mechanism for checking timestamps to identify and analyze forward and backward time steps in a log file.

The number of copies of a message to be transferred from one process to another process in a computer where each process has a differing address space may be reduced through the use of a message-passing data structure. The sending process generates an operating system service call to copy the message to be transferred into the message-passing data structure. The receiving process need not generate a system service request to the kernel in order to retrieve the sent message and also does not require an additional copy of the transferred message to be made by the kernel, in order to read the message content. The data structure permits a mapping of the message into the address space of the receiving process as well as the address space of the kernel. The inter-process mechanism for exchanging messages provides proper flow control, synchronization, and security when two processes exchange data.

A uniform mechanism for building containment hierarchies separates the code / method which actually perform the containment insertion operations on the components from the specification of the containment and then provides an automatic way of obtaining and executing that code when containment hierarchies need to be created. The mechanism consists of an abstract syntax for describing the containment relationships, processing mechanism for creating the containment mechanism, and a registry containing the mechanisms for implementing specific containment policies. Having this abstraction allows an application programmer to be able to construct hierarchies of objects without having to be concerned about the specific details of how that containment is performed. In fact, the details may be deferred until run-time (and even downloaded from elsewhere). Also, having this abstraction significantly simplifies automatic generation of object hierarchy codes, both from the point of view its implementation as well as that of the code that is generated.
