A security mechanism in a database management system enforces processing restrictions stored as metadata to control how different pieces of a multi-nodal application are allowed to access database data to provide data security. The security mechanism preferably checks the data security restrictions for security violations when an execution unit attempts to access the data to insure the nodal conditions are appropriate for access. When the security mechanism determines there is a security violation by a query from an execution unit based on the security restrictions, the security mechanism may send, delay or retry to maintain data security. Nodal conditions herein include time restrictions and relationships with other columns, rows or pieces of information. For example, multiple processing units may be allowed to execute together, but the security mechanism would prohibit these processing units to access specific pieces of information at the same time through the use of metadata in the database.

Data security for a database in a multi-nodal environment

The invention provides a monitoring device preset position setting method, a monitoring device preset position switching method, and corresponding systems. According to the monitoring device preset position setting method and the monitoring device preset position setting system, first, multiple monitoring images of a monitoring device under multiple groups of preset positions and the monitoring risk entropy of each monitoring image are acquired, and then, the monitoring images are sorted according to the monitoring risk entropy from big to small, and one or more groups of preset positions corresponding to the first one or more monitoring images are set as optimal preset positions. According to the monitoring device preset position setting method and the monitoring device preset position setting system, each monitoring image is analyzed automatically and the monitoring risk entropy thereof is acquired, and the preset position corresponding to the monitoring image with the maximum monitoring risk entropy is selected as an optimal preset position of the monitoring device. Thus, a best monitoring effect is ensured, setting is reasonable, and the defect that preset position setting is unreasonable due to inexperienced operators in the prior art is overcome.

The invention relates to a method for monitoring a virtual machine in a cloud environment. The method is characterized in that the virtual machine in the cloud environment is taken as a monitored object, namely, an attack target of an attacker; and a cloud provider serves as a defender and monitors the virtual machine. The method comprises the following specific steps of obtaining income data obtained by the attacker and the defender when the attacker and the defender adopts different actions for the virtual machine in the cloud environment; calculating utility functions of the attacker and the defender; and building a composite attacker behavior model. From the perspective of resource management, based on game theory method analysis, finite resources are efficiently utilized; and when a behavior of the attacker is uncertain, the monitored virtual machine object is determined to obtain an optimal monitoring policy, so that the cloud provider can capture attack behaviors as more as possible, and the benefit of the defender can be maximized.
