43、于可控范围内，并确保变更以一个可以预见的方式进行。变更控制策略应该包括请求变更的发生、批准变更、变更文档化、测试和呈现、实施，以及把变更报告提交给管理层等流程。配置管理变更控制过程通常对服务等级协议的批准无效。 A 不正确。因为一个标准的变更控制策略应该包含测试和呈现。所有变更必须经过全面测试以发现任何不可以预见的结果。根据变更的严重程度和公司的组织结构，变更及其实施可能需要被提交给变更控制委员会。这有助于表现变更的不同目的和结果，以及可能的分支。 C不正确。因为把变更报告提交给管理层的流程应该包含在标准的变更控制策略中。在变更得以实施之后，应该向管理层提交一个总结这次变更的完整报告。这样的报

44、告可以定期提交，从而使得管理层实时了解并继续给予支持。 D 不正确。因为获取变更批准的流程应该包含在标准的变更控制策略中。请求变更的人必须陈述理由，并清楚地阐述变更的好处和可能产生的失误。有时请求者可能被要求进行更多的研究并提供更多的信息之后才被批准变更。2.A change management process should include a number of procedures.

49、.D.Information is made unrecoverable, even with extraordinary effort. 解析：解析：D 正确。清理(purging)指的是在过程周期结束时从系统、存储设备或者带有存储容量的外围设备上移除敏感信息。这个行为的执行方式应该保护数据的敏感性，使得敏感数据不会被重建。删除介质上的文件并不会真正让数据消失，它只是删除了指针，而那些文件中的数据仍然保留在介质上。这就是专门从事恢复数据业务的公司能够在数据被故意或者意外销毁后仍然能够恢复被删除文件的原因所在。即使简单地使用新信息重写介质也不会降低恢复以前所写信息的可能性。这就是为什么需要清零和安全覆盖算法的原因。如果包含高度敏感信息介质的某个部分无法被清理或者清除，那么就必须采用物理销毁的方式。 A 不正确。因为它描述的是消磁(degaussing)，消磁是清理的一种。执行消磁的设备会产生一种强制磁力，把存储介质的磁通密度降为 0。正是这种磁力把介质中的数据擦除了。数据以原子极化的形式存储在磁介质上，消磁用一种强大的磁力改变了这种极化，把它恢复为最初的通量(磁量分布)。 B 不正确。因为当介质需要重新安排到一个不同的区域时就需要清理它。当介质被擦除(删除它们的内容)时，称为被消毒。这意味着擦除信息，从而使得使用常规操作系统命令或者现有的商业取证或
