CISSP 自测题及详解 CBK Domain Access Control System 访问控制系统 1 Answer : A 2 Answer : A 3 Answer : D The smart card or chip contains information pertaining to the subscriber, such as the cell phone number belonging to the subscriber, authentication information, encryption keys, directory of phone numbers, and short saved messages belonging to that subscriber. 4 Answer : C CBK Domain Application and System Development 应用系统开发 1 Answer : A If another user at a lower classification level attempts to create a confidential entry for another military unit using the same identification number as a primary key, a rejection of this attempt would infer to the lower level user that the same identification number existed at a higher level of classification. To avoid this inference Channel of information Chosen value 是密码学里的概念 2 Answer: B 3 Answer: D 4 Answer: A A reference monitor is a system component that enforces access controls on an object. Therefore, the reference monitor concept is an abstract machine that mediates all access of subjects to objects. 5 Answer: D Test Data Method : Processing specially prepared sets of input data integrated test facility : One or more audit module designed into the application during the system development A Parallel Simulation : Using a program that simulates the key features of the application under review 6 Answer: B Polyinstantiation Polyinstantiation is the development of a detailed version of an object from another object using different values in the new object. In database information security, this term is concerned with the same primary key for different relations at different classification levels being stored in the same database. 7Answer: A 8Answer: D The value of a neural network is its ability to dynamically adjust its weights in order to associate the given input vectors with corresponding output vectors. All in one: Application P729 Data mining can look at complex data and simplify it by using fuzzy logic, set theory, and neural networks to perform the mathematical functions and look for patterns in data that are not so apparent. CBK Domain Business Continuity Plan 业务连续性 1 Answer: B 2 Answer: D 3 Answer: D The Disaster Recovery Planning Process This phase involves the development and creation of the recovery plans, which are similar to the BCP process. However, in BCP we were involved in BIA and loss criteria for identifying the critical areas of the enterprise that the business requires to sustain continuity and financial viability; here, we’re assuming that those identifications have been made and the rationale has been created. Now we’re defining the steps we will need to perform to protect the business in the event of an actual disaster. 4 Answer: A 5 Answer: B 6 Answer: A 7 Answer: C CBK Domain Cryptography 密码系统 1 Answer: A 2 Answer: A 3 Answer: A 4 Answer: C Hybrid systems have evolved that use public key cryptography to safely distribute the secret keys used in symmetric key cryptography. 5 Answer: C 6Answer: B Certificate Revocation Lists (CRLs) that denote the revoked certificates. 7 Answer: B 8 Answer: A CBK Domain Law Ethics and Investigation 法律、道德和调查 1 Answer : A 2 Answer : A 3 Answer : D 4 Answer : A 5 Answer : A CBK Domain Operation Security 运作安全 1 Answer: B 2 Answer: A Five generally accepted procedures exist to implement and support the change control process: a. Applying to introduce a change. Requests presented to an individual or group responsible for approving and administering changes. b. Approval of the change. Demonstrating trade-off analysis of the change and justifying it. c. Cataloging the intended change. Documenting and updating the change in a change control log. d. Testing the change. Formal testing of the change. e. Scheduling and implementing the change. Scheduling the change and implementing the change. f. Reporting the change to the appropriate parties. Submitting a full report summarizing the change to management. 3 Answer: D Intent: 意图,攻击尝试可以被审核,但意图不行 4 Answer: A Least Privilege. Least privilege requires that each subject be granted the most restricted set of privileges needed for the performance of their task. It may be necessary to separate the levels of access based on the operator’s job function. A very effective approach is least privilege. Privacy. The level of confidentiality and privacy protection that a user is given in a system. This is often an important component of security controls. Privacy not only guarantees the fundamental tenet of confidentiality of a company’s data, but also guarantees the data’s level of privacy, which is being used by the operator. Compartmentalization: The isolation of the operating system, user programs, and data files from one another in main storage to protect them against unauthorized or concurrent access by other users or programs. Also, the division of sensitive data into small, isolated blocks to reduce risk to the data. Risk Management’s main function is to mitigate risk. Mitigating risk means to reduce the risk until it reaches a level that is acceptable to an organization. Risk Management can be defined as the identification, analysis, control, and minimization of loss that is associated with events. 5 Answer: D Object Reuse is the concept of reusing data storage media after its initial use. Data Remanence is the problem of residual information remaining on the media after erasure, which may be subject to restoration by another user, CBK Domain Physical Security 物理安全 1 Answer : D Fault: 短暂掉电 Surge: 较长的电压过高 Blackout: 较长的掉电 2 Answer : D 3 Answer : A 4 Answer : C Acoustical-seismic detection system: 听觉震动检测系统 5 Answer : D 6 Answer : D 焦距( Focal Length ) 焦距指镜头中心到焦点的距离,通常以毫米 mm 量度。照相机镜头把拍摄场景中的光线投射到胶卷或传感器上。可见的视野范围( FOV , Field of View )由镜头覆盖的场景水平和 垂直距离决定。面积大的传感器和胶卷拥有更大的 FOVs ,并且能够记录场景中的更多信息。 焦距和 FOV 通常都是以 35mm 胶卷为参照的,因为这种格式( 35mm )比较常用。图解见下页 CBK Domain Security Architecture and Mode 安全架构和模型 1 Answer: B Potential Problems: Performance and availability of computing resources The system and networking infrastructure Procedures and transactions Safety and security of personnel Abnormal Events - that can be discovered by an audit Degraded resource availability Deviations from the standard transaction procedures Unexplained occurrences in a processing chain 2 Answer: B 3 Answer: B 4 Answer: D 主流的隐蔽通道标识方法共有 4 种 :(1) 语法信息流法 ;(2) 无干扰法 ;(3) 共享资源矩阵法 ;(4 语义信息流法 . 目前 , 应用最为广泛的是方法 (3) 和方法 (4). 隐蔽通道共有 3 种处理方法 : 消除法、带宽限制法和审计法 . 隐蔽通道分析可以在以下 3 个层次进行 : (a) 描述性顶层规范 DTLS(detailed top-level specification); (b) 形式化顶层规范 FTLS; (c) 源代码 . Shared Resource Matrix methodology, which is an approach that can be applied to a variety of system description forms and can increase the assurance (although it does not guarantee it) that all channels have been found. 5 C 6 D Cascading. One system’s input is obtained from the output of another system (System architecture) Network-related issues of authentication (such as proxies and cascading trust) are beyond the scope of this document. CBK Domain Security Management Practice 安全管理实践 1 Answer: D In order for this security policy to be effective, it must receive approval and support from all the extranet participants (i.e., senior management). The security policy must keep up with the technological pace of the information systems technology Authorization must adhere to the least-privilege principle. 2 Answer: B Analog line: 模拟线路 3 Answer: B 4 Answer: D 5 Answer: A 6 Answer: B 7 Answer: A The overall purpose of a penetration test is to determine the subject’s ability to withstand an attack by a hostile intruder. The reason penetration testing exists is that organizations need to determine the effectiveness of their security measures 8 Answer: A The first type of testing involves the physical infrastructure of the subject. Another type of testing examines the operational aspects of an organization. The final type of penetration test is the electronic test. 9 Answer: B 10 Answer: D CBK Domain Telecommunication and Network Security 电信与网络安全 1 Answer: C 网络层负责路由和寻址功能。 传输层负责端到端的传输控制,完整性检测,数据分割和重组,流量控制等等。 2 Answer: D 3 Answer: A 4 Answer: B The Internet Layer corresponds to the OSI’s Network Layer. It designates the protocols that are related to the logical transmission of packets over the network. This layer gives network nodes an IP address and handles the routing of packets among multiple networks. It also controls the communication flow between hosts. At the bottom of the TCP/IP model, the Network Access Layer monitors the data exchange between the host and the network. The equivalent of the Data Link and Physical layers of the OSI model, it oversees hardware addressing and defines protocols for the physical transmission of data. 5 Answer: C Shanghai Spisec Information Technology Co.,Ltd.
