In the fields of physical security and information security,access control is the selective restriction of access to a place or other resource.The act of accessing may mean consuming,entering,or using.Permission to access a resource is called authorization（授权）．An access control mechanism（71）between a user(or a process executing on behalf of a user)and system resources,such as applications,operating systems,firewalls,routers,files,and databases.The system must first authenticate（验证）a user seeking access.Typically the authentication function determines whether the user is（72）to access the system at all.Then the access control function determines if the specific requested access by this user is permitted.A security administrator maintains an authorization database that specifies what type of access to which resources is allowed for this user.The access control function consults this database to determine whether to（73）access.An auditing function monitors and keeps a record of user accesses to system resources.In practice,a number of（74）may cooperatively share the access control function.All operating systems have at least a rudimentary（基本的）,and in many cases a quite robust,access control component.Add-on security packages can add to the（75）access control capabilities of the OS.Particular applications or utilities,such as a database management system,also incorporate access control functions.External devices,such as firewalls,can also provide access control services.A.cooperatesB.coordinatesC.connectsD.mediates

The objective of (71) is to determine what parts of the application software will be assigned to what hardware. The major software components of the system being developed have to be identified and then allocated to the various hardware components on which the system will operate. All software systems can be divided into four basic functions. The first is (72). Most information systems require data to be stored and retrieved, whether a small file, such as a memo produced by a word processor, or a large database, such as one that stores an organization's accounting records. The second function is the (73), the processing required to access data, which often means database queries in Structured Query Language. The third function is the (请作答此空), which is the logic documented in the DFDs, use cases, and functional requirements. The fourth function is the presentation logic, the display of information to the user and the acceptance of the user's commands. The three primary hardware components of a system are (75).
A. system requirements
B. system architecture
C.application logic
D.application program
