本文将详细讲述 AIX Security Expert的管理和使用方法

本文将详细讲述 AIX Security Expert的管理和使用方法

本文将详细讲述AIX Security Expert的管理和使用方法,当然,前提是,你需要对所有的安全指标、系统参数、系统服务都有比较深入的了解,有可能的话,我将逐步分节的加以介绍AIX系统安全的设计和管理重要性就不用多说了,大大小小的、内部外部的攻击、审计、检查等,无不涉及我们的系统安全,作为AIX系统管理员,构建一个安全可靠的生产系统运行平台,也是份内之事,事实上,如何构建出一种更好、更安全、更可靠、更合理的方式,并将统一个安全规范、安全管理、安全策略部署到IDC内所有的AIX系统,2007年年初,AIX V5.3 推出Technology Level 5,在该TL的版本中,引进了一个新的功能 --- AIX Security Expert,该工具可以在单一界面提供管理 300 多个系统安全设置的能力,而且,IBM AIX V6的版本已经推出,据悉,该功能在V6的版本中继续得到了增强,可以将安全模板直接存储在 Lightweight Directory Protocol (LDAP) 目录中,简化了在整个系统环境中安全性一致的实现。

考虑到将来我们一定会升级AIX操作系统的版本,所以,提前了解、熟悉和掌握这个新的安全配置和管理工具,对我们今后的系统管理不无裨益。

1、获得AIX® Security Expert简单的说,获得AIX Security Expert的功能是非常简单的,两个必要条件1、aix v5 v5.3 or above2、TL : 05 or above验证方式:# oslevel –s2、使用AIX® Security Expert使用一个工具,我们需要从整体上对这个工具有所了解,个人建议通过web system management的方式进行AIX Security Expert的操作和管理,这样更直观,更简单,也不容易出错,而且,安全的设置,其实操作本身是非常简单的,最重要的是,对每一个设置点的把握和理解,还有就是安全策略的制定,而这些,都需要结合具体业务系统的实际需求进行定制。
