The Software Configuration Management (SCM) process defines the need to trace changes, and the ability to verify that the final delivered software has all of the planned enhancements that are supposed to be included in the release. What are the procedures that must be defined for each software project to ensure that a sound SCM process is implemented? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer:
ABCD
The SCM process defines the need to trace changes, and the ability to verify that the final delivered software has all of the planned enhancements that are supposed to be included in the release. It identifies four procedures that must be defined for each software project to ensure that a sound SCM process is implemented. They are as follows:
* 1.Configuration identification: Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. * 2.Configuration change control: Configuration change control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them.
* 3.Configuration status accounting: Configuration status accounting is the ability to record and report on the configuration baselines associated with each configuration item at any moment of time.
* 4.Configuration audits: Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. A functional configuration audit ensures that functional and performance attributes of a configuration item are achieved, while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design documentation.
Fill in the blank with the appropriate security mechanism. is a computer hardware mechanism or programming language construct which handles the occurrence of exceptional events.
Correct Answer:
A
Exception handling is a computer hardware mechanism or programming language construct that handles the occurrence of events. These events occur during the software execution process and interrupt the instruction flow. Exception handling performs the specific activities for managing the exceptional events.
In which of the following alternative processing sites is the backup facility maintained in a constant order, with a full complement of servers, workstations, and communication links ready to assume the primary operations responsibility?
Correct Answer:
B
A hot site is a duplicate of the original site of the organization, with full computer systems as well as near-complete backups of user data. It provides the backup facility, which is maintained in a constant order, with a full complement of servers,
workstations, and communication links ready to assume the primary operations responsibility.
A hot site is a backup site in case disaster has taken place in a data center. A hot site is located off site and provides the best protection. It is an exact replica of the current data center. In case a disaster struck to the data center, administrators just need to take the backup of recent data in hot site and the data center is back online in a very short time. It is very expensive to create and maintain the hot site. There are lots of third party companies that provide disaster recovery solutions by maintaining hot sites at their end. Answer A is incorrect. A cold site is a backup site in case disaster has taken place in a data center. This is the least expensive disaster recovery solution, usually having only a single room with no equipment. All equipment is brought to the site after the disaster. It can be on site or off site. Answer D is incorrect. Mobile sites are self-reliant, portable shells custom-fitted with definite telecommunications and IT equipment essential to meet system requirements. These are presented for lease through commercial vendors. Answer C is incorrect. A warm site is, quite logically, a compromise between hot and cold sites. Warm sites will have hardware and connectivity already established, though on a smaller scale than the original production site or even a hot site. These sites will have backups on hand, but they may not be complete and may be between several days and a week old. An example would be backup tapes sent to the warm site by courier.
You work as a project manager for a company. The company has started a new security software project. The software configuration management will be used throughout the lifecycle of the project. You are tasked to modify the functional features and the basic logic of the software and then make them compatible to the initial design of the project. Which of the following procedures of the configuration management will you follow to accomplish the task?
Correct Answer:
B
Configuration control is a procedure of the Configuration management. Configuration control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. It supports the change of the functional and physical attributes of software at various points in time, and performs systematic control of changes to the identified attributes. Answer C is incorrect. Configuration audits confirm that the configuration identification for a configured item is accurate, complete, and will meet specified program needs. Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. A functional configuration audit ensures that functional and performance attributes of a configuration item are achieved, while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design documentation. Answer D is incorrect. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. Baselining an attribute forces formal configuration change control processes to be effected in the event that these attributes are changed. Answer A is incorrect. The configuration status accounting procedure is the ability to record and report on the configuration baselines associated with each configuration item at any moment of time. It supports the functional and physical attributes of software at various points in time, and performs systematic control of accounting to the identified attributes for the purpose of maintaining software integrity and traceability throughout the software development life cycle.
System Authorization is the risk management process. System Authorization Plan (SAP) is a comprehensive and uniform approach to the System Authorization Process. What are the different phases of System Authorization Plan? Each correct answer represents a part of the solution. Choose all that apply.
Correct Answer:
BCDE
The creation of System Authorization Plan (SAP) is mandated by System Authorization. System Authorization Plan (SAP) is a comprehensive and uniform approach to the System Authorization Process. It consists of four phases: Phase 1 - Pre-certification Phase 2 - Certification Phase 3 - Authorization Phase 4 - Post-Authorization
