Furthermore, the present invention provides for secure transmission of messages to and amongst automation devices utilizing public key cryptography associated with digital certificates.

Rules are used to determine a compliance level for a computing device attempting to access a network. The compliance level may have multiple categories or facets, that may be determined individually or collectively, to determine a score for the computing device. The score may be used to determine whether the computing device should obtain access to the network, the type of access to be granted, or whether remediation should occur and what type of remediation should occur on the computing device to enable the computing device to enjoy greater network privileges. Optionally, the score may be weighted in connection with the user privileges associated with the user as determined during the authentication process, to enable users with greater network access privileges to access the network in situations where other users may not be able to access the network.

To maintain the integrity and operability of enterprise database systems, queries intended for a particular database engine are intercepted, preferably by a separate processing system, prior to being acted upon by the database engine. The query is evaluated to determine its projected impact on available database system resources. The variables evaluated include user rights, administrator-imposed limits to searches, the amount of presently-available system resources, the cost of query and the like. If the query's potential impact does not surpass a predetermined threshold, it is submitted to the search engine. If the query is too resource-intensive or costly, the query may be (i) optimized by a query-optimization system, (ii) stored until more system resources are available, or (iii) rejected.

A configuration management system creates (602) each configuration by assigning a configuration identifier to each configuration. In addition, relational information is computed (706) that indicates the relationships between the configuration and any configurations upon which it is based. The system then tracks (604) changes to files of the configuration by storing information associating each new file version with the configuration identifier. The system also tracks (1210) changes to file properties. A configuration is then reconstructed (608) as of a desired date, by identifying (2104, 2106) the file versions and properties associated with that configuration as of the desired date. A determination is made (2110) whether a user that has requested the file versions has access privileges by first checking a security cache (2600) for the user privileges information. If the information is not on the cache, it is computed from a security table (2800) and stored on the cache. The system automatically compresses (3118) and reconstitutes (3006) file versions that are stored in the version store.

A mechanism for running interactive applications with a minimal set of privileges is disclosed.
