MODEL-DRIVEN SECURITY ASSESSMENT AND VERIFICATION FOR BUSINESS SERVICES

Information security covers many areas within an enterprise. Each area has security vulnerabilities and, hopefully, some corresponding countermeasures that raise the security level and provide better protection. The fundamental concepts in information security are the security model, which outlines how security is to be implemented. A security policy outlines how data is accessed, what level of security is required, and what actions should be taken when these requirements are not met. A security model is a statement that outlines the requirements necessary to properly support and implement a certain security policy. An important concept in the design and analysis of secure systems is the security model, because it incorporates the security policy that should be enforced in the system. A model is a symbolic representation of a policy. It maps the desires of the policy makers into a set of rules that are to be followed by a computer system. In the paper we propose a model driven security assessment and verification for business service. The Security Assessment and Verification verifies whether the Application and Services are secure based on the Service Level Agreement and generates the report on the level of security features. It is designed to help business owners, operators and staff to assess the security of their business. It covers potential areas of vulnerability, and provides suggestions for adapting your security to reduce the risk of crime against your business. A security policy states that no one from a lower security level should be able to view or modify information at a higher security level, the supporting security model will outline the necessary logic and rules that need to be implemented to ensure that under no circumstances can a lower-level subject access a higher-level object in an unauthorized manner. The security policy is an abstract term that represents the objectives and goals a system must meet and accomplish to be deemed secure and acceptable
