【正文】 ws is principaloriented and authorization decisions are based on the identity of an authenticated principal for example the user running code or the user logged into a Web application CAS adds another dimension to security by supporting authorization decisions based on the identity of code not the user who runs the code This is particularly important for mobile code such as controls and applications downloaded from the Inter through Inter Explorer Just because you may be logged into your puter as an administrator do you really want such code to have administrative privileges – probably not if you are concerned about the integrity and security of your machine Jurisdiction Permission represents can perform a protected operation authorization These operations typically include the specific resource access Usually these operations can include access to resources such as files registry work user interface or execution environment Not involving actual resource permissions of a sample is skip verification function Note the SyissionsSecurityPermission class contains a flag the flag to determine whether to permit permission instance receiver skip verification The SecurityPermission class contains the other similar permission flag they cover the core runtime technology if not the proper use of these techniques such as a control for the particular application domain running assembly provides evidence of the capacity may open security holes The core runtime technology is by requesting the caller to protect so that the required SecurityPermission setting appropriate permission flag Access the basic Abstract IPermission interface it requires specific permission types to achieve a standard set of permissions to operate such as the return type and has the same privileges other DnsPermission instance joint or subset Permissions can be sorted to a permission set this permission set represents a variety of resources to access a statement The SyissionSet class represents a collection of permissions This class of methods including Intersect and Union These methods use another PermissionSet as a parameter and provides a PermissionSet the PermissionSet or the two set of permissions of all joint or the two set of the intersection of all authority in the runtime permission set is a simple unsorted set representation With these tools safety system can use permissions set without having to understand each kind of permissions semantics This enables developers to access extension of hierarchical structure without the need to modify the security engine function Note each different types of permissions must be derived from the requirements for any type of permission to implement Standard Authority operating IPermission interface the standard access operations such as joint intersection subset and request method These types of permissions to achieve specific to their permissions that state the type of semantic For example one that contains the name of the file permissions and contains a simple Boolean state permission to produce different results Power limit set A and B permissions set intersection if A and B containing the same permissions for different instances of the type X then A will call X permissions set on the instance of the intersection method without the need to know about the X semantic content of any According to the loading assemblies is provided to the security system of evidence the safety system shall grant a privilege set this permission set represents access protected resources authority In contrast resource is protected by a permission request the request triggers a security check to see whether a specific permission is granted to the resources of all the caller if the request failed will throw an exception known as a link request specific safety inspection it only checks the immediate caller But usually check the caller of the call stack Evidence and Security Policy Code is authenticated and its identity is determined using attributes of the code called evidence Evidence can include an assemblys public key which is part of its strong name its download URL its installed application directory and others Once the code identity has been established the gathered evidence is passed through security policy which ultimately governs the capabilities of the code and what permissions it is granted to access secure resources Default policy ensures that all code installed on a local machine is fully trusted and is granted an unrestricted set of permissions to a。功234。開 a

Inter以快速高效捷便的傳輸特性逐漸被人們接受自 2020網(wǎng)絡(luò)小說的涌現(xiàn)不僅顛覆了傳統(tǒng)的書寫和傳播模式Design and Implementation of the management system for online fiction city Abstract With the constant development of the society the ceaseless progress of science and technology the IT industry is change rapidly the human way of life have an important impact on Inter to fast efficient the transmission properties of the Czech Republic will be gradually accepted by people Since 2020 the work novels appeared not only overthrows the traditional writing and munication mode but also won the peoples favorite This article mainly elaborated the online novel city design and implementation the system uses the ASPSQL Server 2020 as a development tool Online novel city management system based on the readers as the center to establish a plete function easy operation and an information management system Web front to achieve the classification of novels display query online reading and providing member registrat
