D、可以根據(jù)不同環(huán)境造成不同破壞
以下關(guān)于網(wǎng)絡安全設計原則的說法,錯誤的是 ( ) 。
A、充分、全面、完整地對系統(tǒng)的安全漏洞和安全威脅進行分析、評估和檢測,是設計網(wǎng)絡安全系統(tǒng)的必要前提條件
B、強調(diào)安全防護、監(jiān)測和應急恢復。要求在網(wǎng)絡發(fā)生被攻擊的情況下,必須盡可能快地恢復網(wǎng)絡信息中心的服務,減少損失
C、考慮安全問題解決方案時無需考慮性能價格的平衡,強調(diào)安全與保密系統(tǒng)的設計應與網(wǎng)絡設計相結(jié)合
D、網(wǎng)絡安全應以不能影響系統(tǒng)的正常運行和合法用戶的操作活動為前提

The objective of ()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(). 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 (),the processing required to access data,which often means database queries in Structured Query Language. The third function is the (),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 ().
A.a(chǎn)rchitecture design
B.modular design
C.physical design
D.distribution design
A.data access components
B.database management system
C.data storage
D.data entities
A.data persistence
B.data access objects
C.database connection
D.dataaccess logic
A.system requirements
B.system architecture
C.a(chǎn)pplication logic
D.a(chǎn)pplication program
A.computers,cables and network
B.clients,servers,and network
C.CPUs,memories and I/O devices
D.CPUs,hard disks and I/O devices
