ACA网络:4个网络，IP电话网络，管理员和员工，教师和学生以及管理员和教师的域，其中2个网络连接到网关。路由器使用的是700系列Cisco内置防火墙机制。服务器分别是由Dell、Dell和IBM支持的管理和员工广告文件服务器、网络DHCP服务器、内部网和在线学生管理系统服务器。使用OS Win Server 2000和2003版本。创建无线接入点，网络由3COM无线交换机管理器监控。计划阶段是安全顾问将所有网络涉众聚集在一起，以评估当前情况并确定安全修补的目标的阶段。对现行的安全政策进行了评估。ACT拥有默认防火墙和无线网络监控，以及个人工作站的病毒防护软件。因此，策略评估将考虑这些系统的工作情况、用户抱怨等等。将询问网络的不同涉众的安全问题。

行政人员、工作人员和更多的人将参与规划阶段。在这个阶段将确定最佳安全的目标。本报告第5-8节将是建设阶段。在此阶段，安全顾问将与ACT管理员一起开发安全模板计划、定义威胁、测试它们并分阶段对网络进行更改。管理计划也在构建阶段本身中定义。定义了无线网络安全策略。已经可用的元素(如只需要升级的现有安全组件)被标识出来。识别威胁场景、风险管理计划和缓解。测试带有场景修改的计划。系统配置和网络部署，测试bug和最终集成。在管理阶段中，管理员将确保安全系统设计的管理工作一直持续到最终推出。在推出之前的所有步骤都要仔细考虑更改和影响。在最终推出后，管理层将继续确保安全系统符合所需的政策。

ACA Networks: Four networks, IP Phone network, Admin and Staff, Teachers and Student and Domain for Admin and Teachers, with two of the networks connected to a gateway. Router used is a 700 series Cisco with an inbuilt firewall mechanism.Servers are the Administration and staff AD file server, the Network DHCP server, the Intranet and Online Student Management System server, powered by Dell, Dell and IBM respectively. OS Win Server version 2000 and 2003 are used. Wireless access points are created and the network is monitored by 3COM wireless switch manager.The planning phase is that phase where the security consultant would bring together all network stakeholders in order to assess current situation and define the goal of security revamping. The current security policies of ACT are assessed. ACT has default firewall and wireless network monitoring, along with individual workstation virus protection software’s. So the policy assessment would consider how far these systems are working, user complaints, and more.Different stakeholders for the networks would be queried as to their security concerns.

Administrators, staff and more would be involved in the planning phase.Goals and objectives for optimum security would be defined in this stage.Sections 5-8 of this report will be the building phase. This is the phase in which the security consultant will work with the ACT administrators in order to develop security template plans, define threats, test them and roll out the changes to the network in phases. Management initiatives are also defined in the building phase itself.The wireless network security policy is defined.The elements available already such as existing security components only needing upgradation are identified.Identifying threat scenarios, risk management plan and mitigation.Testing plans with scenario modifications.System configuration and network roll out, testing for bugs and final integration.The management phase is one in which the administrator would ensure management of the designing of the security system till the final end roll out. Change and impact are critically considered at all steps prior to roll out. After final roll out, the management will continue to ensure the security system complies with needed policies.
