SSCP Exam Question 52
The major objective of system configuration management is which of the following?
Correct Answer: B
A major objective with Configuration Management is stability. The changes to the system are controlled so that they don't lead to weaknesses or faults in th system. The following answers are incorrect: system maintenance. Is incorrect because it is not the best answer. Configuration Management does control the changes to the system but it is not as important as the overall stability of the system. system operations. Is incorrect because it is not the best answer, the overall stability of the system is much more important. system tracking. Is incorrect because while tracking changes is important, it is not the best answer. The overall stability of the system is much more important.
SSCP Exam Question 53
Which of the following is TRUE regarding Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)?
Correct Answer: A
Explanation/Reference: TCP is a reliable connection-oriented transport for guaranteed delivery of data. Protocols represent certain rules and regulations that are essential in order to have data communication between two entities. Internet Protocols work in sending and receiving data packets. This type of communication may be either connection-less or connection-oriented. In a connection-oriented scenario, an acknowledgement is being received by the sender from the receiver in support of a perfect transfer. Transmission Control Protocol or TCP is such a protocol. On the other hand, UDP or User Datagram Protocol is of the connection-less type where no feedback is being forwarded to the sender after delivery and the data transfer have taken place or not. Though, it's not a guaranteed method, but, once a connection is established, UDP works much faster than TCP as TCP has to rely on a feedback and accordingly, the entire 3-way handshaking takes place. The following answers are incorrect: UDP provides for Error Correction, TCP does not: UDP does not provide for error correction, while TCP does. UDP is useful for longer messages, rather than TCP: UDP is useful for shorter messages due to its connectionless nature. TCP does not guarantee delivery of data, while UDP does guarantee data delivery: The opposite is true.

SSCP Exam Question 55
What is the main purpose of Corporate Security Policy?
Correct Answer: B
Section: Security Operation Adimnistration Explanation Explanation/Reference: A Corporate Security Policy is a high level document that indicates what are management`s intentions in regard to Information Security within the organization. It is high level in purpose, it does not give you details about specific products that would be use, specific steps, etc.. The organization's requirements for access control should be defined and documented in its security policies. Access rules and rights for each user or group of users should be clearly stated in an access policy statement. The access control policy should minimally consider: Statements of general security principles and their applicability to the organization Security requirements of individual enterprise applications, systems, and services Consistency between the access control and information classification policies of different systems and networks Contractual obligations or regulatory compliance regarding protection of assets Standards defining user access profiles for organizational roles Details regarding the management of the access control system As a Certified Information System Security Professional (CISSP) you would be involved directly in the drafting and coordination of security policies, standards and supporting guidelines, procedures, and baselines. Guidance provided by the CISSP for technical security issues, and emerging threats are considered for the adoption of new policies. Activities such as interpretation of government regulations and industry trends and analysis of vendor solutions to include in the security architecture that advances the security of the organization are performed by the CISSP as well. The following are incorrect answers: To transfer the responsibility for the information security to all users of the organization is bogus. You CANNOT transfer responsibility, you can only tranfer authority. Responsibility will also sit with upper management. The keyworks ALL and USERS is also an indication that it is the wrong choice. To provide detailed steps for performing specific actions is also a bogus detractor. A step by step document is referred to as a procedure. It details how to accomplish a specific task. To provide a common framework for all development activities is also an invalid choice. Security Policies are not restricted only to development activities.
