求一篇关于大数据的外文文献加翻译，翻译后的字数在3000到5000，或者其他关于数据库的也行，必重赏啊_sql

童鞋你好！

这个估计需要自己搜索了！

网上基本很难找到免费给你服务的！

我在这里给你点搜索国际上常用的外文数据库：

----------------------------------------------------------

❶ISI web of knowledge Engineering Village2

❷Elsevier SDOL数据库IEEE/IEE(IEL)

❸EBSCOhost RSC英国皇家化学学会

❹ACM美国计算机学会 ASCE美国土木工程师学会

❺Springer电子期刊 WorldSciNet电子期刊全文库

❻Nature周刊 NetLibrary电子图书

❼ProQuest学位论文全文数据库

❽国道外文专题数据库 CALIS西文期刊目次数据库

❾推荐使用ISI web of knowledge Engineering Village2

-----------------------------------------------------------

中文翻译得自己做了，实在不成就谷歌翻译。

弄完之后，自己阅读几遍弄顺了就成啦！

学校以及老师都不会看这个东西的！

外文翻译不是论文的主要内容！

所以，很容易过去的！

祝你好运！

论文查找外文文献的方法技巧

1、提取关键词

从论文题目里提取，值得注意的是：参考文献不需要完全和标题一致，有时候搜索不到外文的时候，也可以把选择的关键词扩大一下范围，找些类似的也是可以的。

2、翻译关键词

可以上网进行关键词的翻译，翻译中有时候会出现一些例句，例句一般都是比较专业的描述，避免有的时候一些直译在搜索时搜不到结果。还有如果关键词比较专业，建议先看一下相关的毕业论文里面是怎么翻译这个关键词的，了解了以后进行翻译会更有效。

3、进入学校图书馆

一般学校都是有电子资源库的，同学们可以利用学校的资源，帮助自己找到论文所需要的外文文献资料。

前面是综合介绍，最后有其他资料的链接

Database security is the system, processes, and procedures that protect a database from unintended activity. Unintended activity can be categorized as authenticated misuse, malicious attacks or inadvertent mistakes made by authorized individuals or processes. Database security is also a specialty within the broader discipline of computer security.

Traditionally databases have been protected from external connections by firewalls or routers on the network perimeter with the database environment existing on the internal network opposed to being located within a demilitarized zone. Additional network security devices that detect and alert on malicious database protocol traffic include network intrusion detection systems along with host-based intrusion detection systems.

Database security is more critical as networks have become more open.

Databases provide many layers and types of information security, typically specified in the data dictionary, including:

* Access control

* Auditing

* Authentication

* Encryption

* Integrity controls

Database security can begin with the process of creation and publishing of appropriate security standards for the database environment. The standards may include specific controls for the various relevant database platformsa set of best practices that cross over the platformsand linkages of the standards to higher level polices and governmental regulations.

An important procedure when evaluating database security is performing vulnerability assessments against the database. A vulnerability assessment attempts to find vulnerability holes that could be used to break into the database. Database administrators or information security administrators run vulnerability scans on databases to discover misconfiguration of controls within the layers mentioned above along with known vulnerabilities within the database software. The results of the scans should be used to harden the database in order to mitigate the threat of compromise by intruders.

A program of continual monitoring for compliance with database security standards is another important task for mission critical database environments. Two crucial aspects of database security compliance include patch management and the review and management of permissions (especially public) granted to objects within the database. Database objects may include table or other objects listed in the Table link. The permissions granted for SQL language commands on objects are considered in this process. One should note that compliance monitoring is similar to vulnerability assessment with the key difference that the results of vulnerability assessments generally drive the security standards that lead to the continuous monitoring program. Essentially, vulnerability assessment is a preliminary procedure to determine risk where a compliance program is the process of on-going risk assessment.

The compliance program should take into consideration any dependencies at the application software level as changes at the database level may have effects on the application software or the application server. In direct relation to this topic is that of application security.

Application level authentication and authorization mechanisms should be considered as an effective means of providing abstraction from the database layer. The primary benefit of abstraction is that of a single sign-on capability across multiple databases and database platforms. A Single sign-on system should store the database user's credentials (login id and password), and authenticate to the database on behalf of the user.

Another security layer of a more sophisticated nature includes the real-time monitoring of database protocol traffic (SQL) over the network, and/or local monitoring of database activity using software agents. Analysis can be performed on the traffic for known exploits or network traffic baselines can be captured overtime to build a normal pattern used for detection of anomalous activity that could be indicative of intrusion. These systems can provide a comprehensive Database audit trail in addition to the intrusion detection (and potentially protection) mechanisms.

In addition to using external tools for monitoring or auditing, native database audit capabilities are also available for many database platforms. The native audit trails are extracted on a regular basis and transferred to a designated security system where the database administrators do not have access. This ensures a certain level of segragation of duties that may provide evidence the native audit trails were not modified by authenticed administrators. Generally, the native audit trails of databases do not provide sufficient controls to enforce separation of dutiestherefore, the network and/or kernel module level host based monitoring capabilities provides a higher degree of confidence for forsenics and preservation of evidence.

After an incident occurs, the usage of Database Forensics can be employed to determine the scope.

A database security program should include the regular review of permissions granted to individually owned accounts and accounts used by automated processes. The accounts used by automated processes should have appropriate controls around password storage such as sufficient encryption and access controls to reduce the risk of compromise. For individual accounts, a two-factor authentication system should be considered in a database environment where the risk is commensurate with the expenditure for such an authentication system.

In conjunction with a sound database security program, an appropriate disaster recovery program should exist to ensure that service is not interrupted during a security incident or any other incident that results in an outage of the primary database environment. An example is that of replication for the primary databases to sites located in different geographical regions.
