四 事件分类和风险程度分析 一 物理层的安全风险分析 1 系统环境安全风险 1 水灾 火灾 雷电等灾害性故障引发的网络中断 系统瘫痪 数据被毁等 2 因接地不良 机房屏蔽性能差引起的静电干扰或外界的电磁干扰使系统不能正常工作 3 机房电力设备和其它配套设备本身缺陷诱发信息系统故障 4 机房安全设施自动化水平低 不能有效监控环境和信息系统工作 5 其它环境安全风险 2 物理设备的安全风险由于信息系统中大量地使用了网络设备如交换机 路由器等 服务 器 移动设备 使得这些设备的自身安全性也会直接关系信息系统和各种网络应用的正常 运转 例如 路由设备存在路由信息泄漏 交换机和路由器设备配置风险等 二 网络安全风险 1 网络体系结构的安全风险 网络平台是一切应用系统建设的基础平台 网络体系结构是否按照安全体系结构和安全机 制进行设计 直接关系到网络平台的安全保障能力 医院的网络是由多个局域网和广域网 组成 网络体系结构比较复杂 内部应用信息网 Internet 网之间是否进行隔离及如何进 行隔离 网段划分是否合理 路由是否正确 网络的容量 带宽是否考虑客户上网的峰值 网络设备有无冗余设计等都与安全风险密切相关 2 网络通信协议的安全风险 网络通信协议存在安全漏洞 网络黑客就能利用网络设备和协议的安全漏洞进行网络攻击 和信息窃取 例如未经授权非法访问内部网络和应用系统 对其进行监听 窃取用户的口 令密码和通信密码 对网络的安全漏洞进行探测扫描 对通信线路和网络设备实施拒绝服 务攻击 造成线路拥塞和系统瘫痪 3 网络操作系统的安全风险 网络操作系统 不论是 IOS Android 还是 Windows 都存在安全漏洞 一些重要的网络 设备 如路由器 交换机 网关 防火墙等 由于操作系统存在安全漏洞 导致网络设备 的不安全 有些网络设备存在 后门 back door 三 系统安全风险 1 操作系统安全风险 操作系统的安全性是系统安全管理的基础 数据库服务器 中间层服务器 以及各类业务 和办公客户机等设备所使用的操作系统 不论是 Win2008 XP 7 还是 Unix 都存在信息安 全漏洞 由操作系统信息安全漏洞带来的安全风险是昀普遍的安全风险 2 数据库安全风险 所有的业务应用 决策支持 行政办公的信息管理核心都是数据库 而涉及医院运行的数 据都是昀需要安全保护的信息资产 不仅需要统一的数据备份和恢复以及高可用性的保障 机制 还需要对数据库的安全管理 包括访问控制 敏感数据的安全标签 日志审计等多 方面提升安全管理级别 规避风险 虽然 目前医院的数据库管理系统可以达到较高的安 全级别 但仍存在安全漏洞 建立在其上的各种应用系统软件在数据的安全管理设计上也 不可避免地存在或多或少的安全缺陷 需要对数据库和应用的安全性能进行综合的检测和 评估 We will continue to improve the company s internal control system and steady improvement in ability to manage and control optimize business processes to

families of the staff in the new year good health happy happy 3 应用系统的安全风险 为优化整个应用系统的性能 无论是采用 C S 应用模式或是 B S 应用模式 应用系统都 是其系统的重要组成部分 不仅是用户访问系统资源的入口 也是系统管理员和系统安全 管理员管理系统资源的入口 桌面应用系统的管理和使用不当 会带来严重的安全风险 例如当口令或通信密码丢失 泄漏 系统管理权限丢失 泄漏时 轻者假冒合法身份用户 进行非法操作 重者 黑客 对系统实施攻击 造成系统崩溃 4 病毒危害风险 计算机病毒的传播会破坏数据信息 占用系统资源 影响计算机运行速度 引起网络堵塞 甚至瘫痪 尽管防病毒软件安装率已大幅度提升 但如果没有好的防毒概念 从不进行病 毒代码升级 而新病毒层出不穷 因此威胁性愈来愈大 5 黑客入侵风险 一方面风险来自于内部 入侵者利用 Sniffer 等嗅探程序通过网络探测 扫描网络及操作系 统存在的安全漏洞 如网络 IP 地址 应用操作系统的类型 开放哪些 TCP 端口号 系统 保存用户名和口令等安全信息的关键文件等 并采用相应的攻击程序对内网进行攻击 入 侵者通过拒绝服务攻击 使得服务器超负荷工作以至拒绝服务甚至系统瘫痪 另一方面风险来自外部 入侵者通过网络监听 用户渗透 系统渗透 拒绝服务 木马等 综合手段获得合法用户的用户名 口令等信息 进而假冒内部合法身份进行非法登录 窃 取内部网重要信息 或使系统终止服务 所以 必须要对外部和内部网络进行必要的隔离 避免信息外泄 同时还要对外网的服务请求加以过滤 只允许正常通信的数据包到达相应 主机 其它的请求服务在到达主机之前就应该遭到拒绝 四 应用安全风险 1 身份认证与授权控制的安全风险 依靠用户 ID 和口令的认证很不安全 容易被猜测或盗取 会带来很大的安全风险 为此 动态口令认证 CA 第三方认证等被认为是先进的认证方式 但是 如果使用和管理不当 同样会带来安全风险 要基于应用服务和外部信息系统建立基于统一策略的用户身份认证 与授权控制机制 以区别不同的用户和信息访问者 并授予他们不同的信息访问和事务处 理权限 2 信息传输的机密性和不可抵赖性风险 实时信息是应用系统的重要事务处理信息 必须保证实时信息传输的机密性和网上活动的 不可抵赖性 能否做到这一点 关键在于采用什么样的加密方式 密码算法和密钥管理方 式 采用国内经过国家密码管理委员会和公安部批准的加密方式 密码算法和密钥管理技 术来强化这一环节的安全保障 3 管理层安全风险分析 安全的网络设备要靠人来实施 管理是整个网络安全中昀为重要的一环 认真地分析管理 所带来的安全风险 并采取相应的安全措施 责权不明 管理混乱 安全管理制度不健全 及缺乏可操作性等都可能引起管理安全的风险 当网络出现攻击行为或网络受到其它一些安全威胁时 如内部人员的违规操作等 无法进 行实时的检测 监控 报告与预警 同时 当故障发生后 也无法提供黑客攻击行为的追 踪线索及破案依据 即缺乏对网络的可控性与可审查性 这就要求人们必须对站点的访问 活动进行多层次的记录 及时发现非法入侵行为 五 预防预警 一 完善网络与信息安全突发公共事件监测 预测和预警制度 加强对各类网络与信息安全突发事件和可能引起突发网络与信息安全突发公共事件的有关 信息的收集 分析 判断和持续监测 当检查到有网络与信息安全突发事件发生或可能发 We will continue to improve the company s internal control system and steady improvement in ability to manage
