Security constraint is a type of declarative security, which specifies the protection of web content. It also specifies access privileges to a collection of resources by using the URL mapping. A deployment descriptor is used to define the security constraint. Security constraint includes the following elements: Web resource collection Authorization constraint User data constraint Answer: A is incorrect. Code Access Security (CAS), in the Microsoft .NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions. When the CLR (common language runtime) loads an assembly it will obtain evidence for the assembly and use this to identify the code group that the assembly belongs to. A code group contains a permission set (one or more permissions). Code that performs a privileged action will perform a code access demand, which will cause the CLR to walk up the call stack and examine the permission set granted to the assembly of each method in the call stack. The code groups and permission sets are determined by the administrator of the machine who defines the security policy. Answer: D is incorrect. Access Management is used to grant authorized users the right to use a service, while preventing access to non- authorized users. The Access Management process essentially executes policies defined in IT Security Management. It is sometimes also referred to as Rights Management or Identity Management. It is part of Service Operation and the owner of Access Management is the Access Manager. Access Management is added as a new process to ITIL V3. The sub-processes of Access Management are as follows: Maintain Catalogue of User Roles and Access Profiles Manage User Access Requests Answer: C is incorrect. Configuration Management (CM) is an Information Technology Infrastructure Library (ITIL) IT Service Management (ITSM) process. It tracks all of the individual Configuration Items (CI) in an IT system, which may be as simple as a single server, or as complex as the entire IT department. In large organizations a configuration manager may be appointed to oversee and manage the CM process.
