Cloud Storage Mechanism Of Security Policy

Cloud computing, security and cloud storage came into people's lives gradually, become a hot research, and its related technologies have been gradually into the computer and related industries. With the advent of modern information society, the security of data storage becomes increasingly important. In this paper, the strategy of traditional storage as a starting point to compare the improvement of its storage strategy to meet the needs of cloud security storage strategy.Policy storage technology is used to store user-created policies and related policy information. Strategy warehouse can centrally manage storage and processing of multiple strategies and related information. Popular strategy for storage is usually stored in a relational database or directory server storage policy strategy, it can be fixed with some file formats, such as XML file format.Relational database using entity relationship model is to organize data in the database, using a collection of mathematical concepts and algebraic approach to the relationship between various types of database and data. LDAP is the Lightweight Directory Access Protocol, the network has now become a kind of directory services to provide open IETF standards.However, the above two strategies are all stored in static storage strategies, and in actual use, there are a large number of policy updates and changes, the two static policies are stored on the show themselves were insufficient. To solve this problem, which introduces the formal concept analysis based on the dynamic storage strategies. Different from the static strategy, dynamic strategy can adapt to changing policy better, can update their strategies in real-time warehouse, in order to secure the network environment to adapt to the cloud changing customer requirements and constantly changing mix of strategies, changing the local policy and network conflict between policy, this paper design a strategy based on formal concept analysis storage model. Meet the definition of the problem domain based on the actual situation in the form of this background, the background is constructed according to the form of all the nodes and edges to complete the concept lattice model construction, resulting in objects and their partial order between attributes is constructed in line with the actual situation Strategy warehouse.
