服务器安全需要注意的几个方面？

服务器的核心技术相对复杂，专业人员稀少，尤其在病毒技术快速更新迭代的前提下，安全问题更为突出。这里提供一些实际工作中总结出的安全防护经验，以供参考。

一，增强网络整体安全

许多用户都知道，大多数攻击会通过系统漏洞进入，因此及时升级并打上补丁是必须要做的，但对服务器来说，只做这些是远远不够的。

实际上，很多病毒不需要直接攻击服务器，而可以通过入侵其中一台计算机而控制整个网络。因为现在很多的网络都是通过域来管理，只要侵入了其中一台计算机，那么从这台计算机再侵入服务器就会变得简单很多。

因此，想要安全必须从整个网络出发。例如制定管理规范，限制计算机网络行为，禁止随意下载软件等制度。其次，通过软件及硬件来管理整个网络，确保整体的安全。

二，加强本地文件安全

企业可以根据每个用户的特点，单独为其制定特殊的访问权限，而不是使用统一的权限，以减少可能存在的安全隐患。

其次，将本地文件的FAT格式转换为更安全的NTFS格式，并通过专门的检测软件对文件进行24小时的监视，并需要重点关注相关服务器操作的日志。

三，备份

这是老话题了，但往常的备份通常是在同一台服务器上建立一个备份区，以保持数据，但一旦服务器损坏，所有数据仍可能会全部丢失。

因此，如果条件允许，不妨将甲服务器的数据保存到乙服务器，再将乙服务器的数据保存到一个服务器，进行交叉备份。当然，这种做法投资会很大。
