Category:Page specific user rights extensions/zh

The Page specific user rights extensions category contains various extensions that attempt to restrict a user's access to specific pages based on the namespace, category links, and/or title patterns. Before installing one of these extensions, users should be aware that such extensions are likely to exhibit three significant problems:

• caching problems: MediaWiki's page caching facilities do not currently support rights-specific caching. That means MediaWiki caches one versions of a page and then serves that page to everyone without rechecking to see if the next user has the proper rights. Any extension that tries to exclude or hide part of a page based on user rights is likely to result in performance declines (if caching is turned off) and/or security leaks when a page cached for a user with higher rights is later viewed by a user with lesser rights.
• multiple exit paths: Page content has many exit paths in MediaWiki: direct page views, excerpts inserted into search results, special pages, RSS feeds, and numerous extensions that read directly from the MediaWiki database. There is no one exit path that either the MediaWiki core or its extensions rely on. Hence it is virtually impossible for any extension to provide full security.
• system security: Content management security is inseparable from overall system security. The default MediaWiki configuration places database passwords in plain text on a file located on the same server as the MediaWiki installation. There is no attempt to secure the host web server or underlying database. If the underlying system is insecure, any extension added on top of that system is also insecure.

如果您需要按页面或部分页面的访问控制，建议您安装适当的内容管理包。 MediaWiki的最初目的并不是提供按页面的访问限制，并且几乎所有添加这一功能的措施或补丁都或多或少存在缺陷，这可能导致暴露机密数据。 对于任何数据泄露，我们不承担任何责任。 更多详情请参见授权扩展的安全问题
