The Prelude Library (libprelude) is the glue that binds all aspects of Prelude together. Prelude is a hybrid Intrusion Detection framework implementing an open communication layer for use by any security application. libprelude is a library that enables Prelude components to communicate with the Prelude concentrator. It also makes it easy for third party software to be made 'Prelude Aware' (able to communicate with Prelude components). It provides common, useful features used by every sensor. License: GNU General Public License (GPL) Changes: This release supports TLS settings specification through the "tls-options" configuration entry. It works around a rare compression protocol negotiation problem. Variable substitution in Prelude configuration files is implemented. IDMEF criteria with multiples values for a single path are allowed (eg: alert.classification.text = (A || B || C || D). Negation of whole idmef-criteria has been implemented. A possible IDMEFCriteria match problem has been fixed. An API consistency issue that could lead to unexpected behavior has been fixed. There are various other bugfixes.
