Patent number: 8719226Abstract: A database enables versioning for objects stored in the database via a “snapshot” operation. In one implementation, a device performs a snapshot operation in which a snapshot object, representing a logical view of database objects at a time at which the snapshot operation is performed, is created and stored in the database. In response to a request to store a modified version of a database object, the modified version of the database object is written to replace the previous version of the database object when the database object was last modified after the most recent snapshot operation. Further, in response to the request to store the modified version of the database object, the modified version of the database object is inserted in the database when the previous version of the database object was last modified before the most recent snapshot operation.Type: GrantFiled: July 16, 2009Date of Patent: May 6, 2014Assignee: Juniper Networks, Inc.Inventors: Tong Jiang, Jianguo Hu, Jian Jin

Publication number: 20050203881Abstract: Embodiments of the present invention provide techniques for monitoring a database system for anomalous activity. User behavior information relative to a subject database being monitored may be automatically collected, analyzed and compared with one or more policies to detect anomalous activity. Embodiments collect user behavior data regarding the subject database from a variety of sources, including an audit trail and dynamic views in cooperation with the database management system of the database. Embodiments employ one or more of statistics-based intrusion detection (SBID) and rule-based intrusion detection (RBID) to detect anomalous database activity. If suspicious database access that deviate from the normal usage pattern are detected, a targeted operation, such as alerting the responsible security officers, generating reports, email alerts or the like, is performed.Type: ApplicationFiled: March 9, 2004Publication date: September 15, 2005Inventors: Akio Sakamoto, Chung-Kuang Chou, Wani Tang, Jianguo Hu
