    不管人们喜欢与否,现在企业里的网管们一般都要承担起监控公司员工使用网络或计算机行为的任务,因为有的公司老板可能需要了解他的员工在上班时间访问了哪些网站,发送或接受了哪些文件,甚至在发送的电子邮件中说了些什么。因为这些员工行为有可能会对公司的利益造成损失,例如上班时间做工作无关的事情,或泄露公司机密信息等。常用方法如下:

    一、通过审核策略监控员工对文件、文件夹等的访问
    在一个Windows网络中,通过启用操作系统中自带的审核策略功能,网管可以知道员工打开了哪些文件或文件夹,或者曾经尝试打开哪些不具有权限的文件或文件夹。在Windows 2000以后的Windows系统中,审核功能是借助于组策略来实现的。只需要两步即可建立起对某些文件或文件夹的审核功能:

    1、首先,你必须在组策略设置界面中设置审核功能。图1、

    2、然后你要在你想审核的文件或文件夹的属性中设置审核。图2、

设置审核对象

    关于如何设置审核的详细步骤,请参阅微软的知识库文章KB article 310399 (http://support.microsoft.com/?kbid=310399)。

    二、检查缓存的Web文件
    假若公司内的计算机数量并不多,那么网管如果想查看公司的用户都访问了哪些站点,实际上并不需要专门的软件就可以实现这个目的,只需要检查web浏览器的缓存文件夹(在IE浏览器中通常叫做Internet临时文件)。IE浏览器为了让用户可以快速的显示已经访问过的页面,把页面的副本和用户下载的图片都被存放在这儿。但是,一些聪明的用户可能会删除临时文件夹中的内容,以免被你查看。图3、

员工上网产生的临时文件

    但是网管可以使用微软的免费工具Shared Computer Toolkit中的用户限制工具,来拒绝用户访问IE浏览器中工具菜单的Internet选项功能,来避免用户直接从这儿清除访问历史和临时Internet文件。

    三、在防火墙上监控Web访问
    另一种监控用户正在访问的站点的方法是在防火墙进行设置,通过用户的帐号、IP地址或计算机名等信息来查看用户的访问记录。企业级别的防火墙,像微软的ISA Server、思科的PIX和CheckPoint的Firewall-1等,或者本身具有这种内置的报表功能,或者通过插件功能来提供用户访问站点历史记录报表的功能,使用这些功能可以来查看这些访问历史记录。很多防火墙都提供用户访问记录分析功能,通过该功能提供多种方式对用户的访问纪录计行查询和统计分析,包括:按时间段、按访问地址范围、按源地址范围、按协议类型等。还有用户访问内容监控,提供对用户访问内容的监控,鉴别用户身份,分析用户访问目标地址,用户访问的内容,用户是否访问过非法网站等功能。如果你的公司使用了防火墙的话,那么可以仔细的看一下帮助文档,来了解一下如何利用这个功能。

Explain the role of InnoDB redo logs and undo logs.Explain the role of InnoDB redo logs and undo logs.Apr 15, 2025 am 12:16 AM

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AM

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB

Describe the different SQL transaction isolation levels (Read Uncommitted, Read Committed, Repeatable Read, Serializable) and their implications in MySQL/InnoDB.Describe the different SQL transaction isolation levels (Read Uncommitted, Read Committed, Repeatable Read, Serializable) and their implications in MySQL/InnoDB.Apr 15, 2025 am 12:11 AM

MySQL/InnoDB supports four transaction isolation levels: ReadUncommitted, ReadCommitted, RepeatableRead and Serializable. 1.ReadUncommitted allows reading of uncommitted data, which may cause dirty reading. 2. ReadCommitted avoids dirty reading, but non-repeatable reading may occur. 3.RepeatableRead is the default level, avoiding dirty reading and non-repeatable reading, but phantom reading may occur. 4. Serializable avoids all concurrency problems but reduces concurrency. Choosing the appropriate isolation level requires balancing data consistency and performance requirements.

MySQL vs. Other Databases: Comparing the OptionsMySQL vs. Other Databases: Comparing the OptionsApr 15, 2025 am 12:08 AM

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

How does MySQL index cardinality affect query performance?How does MySQL index cardinality affect query performance?Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL: Resources and Tutorials for New UsersMySQL: Resources and Tutorials for New UsersApr 14, 2025 am 12:16 AM

The MySQL learning path includes basic knowledge, core concepts, usage examples, and optimization techniques. 1) Understand basic concepts such as tables, rows, columns, and SQL queries. 2) Learn the definition, working principles and advantages of MySQL. 3) Master basic CRUD operations and advanced usage, such as indexes and stored procedures. 4) Familiar with common error debugging and performance optimization suggestions, such as rational use of indexes and optimization queries. Through these steps, you will have a full grasp of the use and optimization of MySQL.

Real-World MySQL: Examples and Use CasesReal-World MySQL: Examples and Use CasesApr 14, 2025 am 12:15 AM

MySQL's real-world applications include basic database design and complex query optimization. 1) Basic usage: used to store and manage user data, such as inserting, querying, updating and deleting user information. 2) Advanced usage: Handle complex business logic, such as order and inventory management of e-commerce platforms. 3) Performance optimization: Improve performance by rationally using indexes, partition tables and query caches.
