Abstract:
In this modern world, organizations use different security solutions to protect their sensitive and critical business data. This need of protection is a very important for organizations and need to be over emphasized. Data Loss Prevention (DLP) is one of the efficient ways of preventing this Data Loss. DLP identifies and stops the unauthorized actions of copying or sending sensitive data, both deliberately or/and accidentally. This solution is developed to detect data leak incidents timely and this is done by monitoring data. It is, without any doubt, appropriate for business activities of organization because it does not disrupt the work flow. Data loss prevention is not only suitable for protecting structured data but also deals with unstructured data. DLP helps organizations in preventing data loss of sensitive information like Personal identifiable, financial, trade secrets etc. and act as a preventive measure.
This thesis has main aim of presenting all the essential information and describing the key terms about data loss prevention, in a simple and understandable way. We have tried to solve sensitive data loss problem and tried to develop an effective and working DLP solution. This has been carried out by conducting a comprehensive study of research on Data Loss Prevention technology and by analyzing already developed solutions. A system architecture is presented, which is designed to implement the basic requirements of a DLP. After the careful implementation of design, we analyzed the system and evaluated with test case and propositions are formed to decrease the defects and make system more efficient. A recent technology i.e. Cloud DLP, which is very famous and used now a days, has been taken into account as future research in this thesis.
