A novel method to classify organizational data using CIA tree approach

Abstract

Data classification plays an important role in an organizational information and communication technology. An efficient data classification technique reduces the complexity of data management.Here we focusing the main security threats such as Confidentiality(C), Integrity (I) and Availability (A).A tree approach is used for data classification.CIA tree is a binary tree which each level represents confidentiality, Integrity and Availability. The three tree approaches are: -Binary tree approach, weighted tree approach and Complex network approach. The binary tree approach directs user into a specified path, where the file gets a path value. In weighted tree approach user get four choices based on root value. Left or right sub tree is activated at a time based on the root value. User can select a value depends on the security of the file. In Complex network approach the full network is activate every time and user can select a value from eight different values. The security, accuracy, processing speed etc of each tree varies differently Index Terms-CIA tree, weighted approach, binary tree approach, complex network approach

An enhanced security tree to secure cloud data

“…The level of security rating is depended on the requirement of the user. A dictionary based string matching algorithm is carried out at the root of the weighted CIA tree [20]. Files can be classified based on its confidentiality.…”

“…Protected file needs average level of security and public files have no security. An automatic data classification system can be used for file classification [2][3]. The user data will pass through an automatic data classification system and after classification the data can be categorized into sensitive, confidential, private and public.…”
