\n3.网络架构的优化：\n优化现有的网络系统，实现与浙江省内各市县区港航局、交通局、客运站内各相关横向部门之间的互联互通。\n4.指挥中心的优化：\n根据需求设计建设浙江省水上客运交通大数据智能指挥中心。\n5.各应用的实施建设：\n分阶段、分步骤建设交通流量检测应用、水上客运综合管理平台等综合信息监控应用，实现应急指挥功能。\n 其建设思路为：\n通过对水上客运交通管理信息化系统发展趋势和存在问题的总结与分析，浙江省水上客运大数据监管系统项目建设应从以下几个方面着手：\n1.动态化\n节点和系统能够即时采集并传输交通信号，从而动态地反映和判别水路交通系统 的运行状况，并支持动态实时的水路交通管理。\n2.全局化\n低成本使得传感器节点的大规模部署经济可行，按照“共性平台+应用子集” 的模式，不同应用场景和应用领域统一在相同的“共性平台”体系架构下，既避 免了智慧交通系统建设的重复投资，又保证了全局的和局部的系统交通信息的全 面掌握。\n3.自动化\n多种类异构节点的叠加部署实现了信息采集手段的多样性，结合协同处理和 模式识别，能够保证智慧交通系统判知和决策的准确性和自动化，减少人工干预 工作量和交通管理资源投入。\n4.智能化\n基于物联网技术的智慧交通系统具有可感知、可判断、可控制、可管理，以 及自动、动态、全局的基本智能特征。\n5.前瞻性\n浙江省水路交通大数据监管系统的建设应站在浙江省智慧交通大数据的统一框架下进行整体设计，以智能化水路交通管理需求为导向，以物联网技术为代表的新一代信息技术为支撑，建立完善的智慧交通框架体系。\n 浙江省水路交通大数据监管系统项目以浙江省智能交通大数据监管系统的框架体系为基础，严格遵循浙江省智慧交通的规范标准，以政务云平台为依托，建设和完善浙江省内的水路交通数据采集体系，在 此基础上根据实际情况通过自建、租用、代建等多种方式建设满足实际需求的应用系统。\n水上客运数据平台逻辑规划：\n（1）基础数据库群 \n基础数据库是共享程度最高的数据，描述对象或环境的基本信息，为行业管理和信息服务提供基础数据支撑，这类数据具有较低的变化速度，但系统间的共 享程度很高。通过对交通行业的信息实体进行归类、抽象，形成交通行业的信息 领域，对这些信息领域的数据实体进行数据建模，形成统一的数据模型，消除系 统之间的差异。\n基础数据库分成：交通参与者、交通工具、交通设施、运输网络、地域、基 础地理、行业标准、元数据、系统管理、系统安全、监控告警、容灾备份等几个 基础信息域。\n（2）业务数据库群 \n业务数据库是交通运输系统信息化应用运行过程中产生的数据，面向不同的交通应用存放相关的规则、业务、运营数据等，存放系统运行或从外围系统抽取 的各层面交通业务数据，对于交通数据平台来说有两个层面的数据:\na、 应用整合库 \n整合交通各领域运营数据，形成按主题分类的面向运营的准实时数据，提供统一的企业数据视图，主要包括：不可预见性较强的交通突发事件的相关信息； 影响交通运行安全的相关环境信息；描述交通流状态的定性定量特征的物理量 (称为交通流参数)的相关信息；道路作为允许机动车通行的地方所应满足的条件 以及机动车在道路上应遵守的规则，如: 临时交通管制，施工信息等。\nb、应用私有库 \n由交通数据平台提供存储区，用于存放基于交通数据平台搭建的应用运营数据，这些数据与其它数据库进行隔离，专用于某个应用，包括面向交通管理部门 应用功能，管控平台，路政管理等。\n（3）主题数据库群 \n主题数据库来源于业务数据库和基础数据库，采用面向主题的方式，对原始数据进行分析与挖掘，形成针对某一主题的综合数据库，为综合应用提供数据支 撑，支持交通资源数据的统计分析和综合展现，提供对交通资源的分析结果的查 询，包括综合分析，决策支持，路网规划分析数据，城市出行分析数据，交通仿 真分析数据，城市环境分析主题数据。\n\n\n 数据质量管理：\n数据质量管理包括管理业务元数据（主要指对 IT 系统的数据实体和数据处 理的业务化描述，包括业务规则、业务术语、统计口径、信息分类等）、技术元 数据（主要指用来描述数据实体和数据处理过程中的技术细节和处理规则，如表 结构、ETL 映射关系等）和操作元数据（主要指对项目管理、IT 运维、IT 资源 设备等相关信息的描述），通过元数据监控数据的产生、处理、存储、应用、存 档各环节的数据质量，确保数据的准确性、完整性和一致性。\n水路客运数据资源分类\n浙江省水路客货运数据中心数据来源复杂、种类繁多，可将数据分为港口数据、 水路数据、旅客数据、车辆过渡数据以及共享数据五大类。如下表所示。\n水路客运数据资源分类如下：\n序号 数据类别 数据项 数据来源\n1 港航数据 港口作业区监控数据 市港航局 以及港口 管理单位\n 水上客运站信息 \n 水上航线信息 \n 水运航班信息 \n2 水路数据 观测站点交通流量 市水路局 以及高速 业主单位\n 站场道路基础信息 \n 可变情报板信息 \n 可变情报板位置 \n 码头基础数据 \n 客运站基础数据 \n 停车场基础数据 \n 候船大厅基础数据 \n 加油站信息 \n 监控点信息 \n 服务区信息 \n 水路养护动态数据 \n 水路路政巡查动态数据 \n 易滑坡路段预警等数据 \n3 质监数据 水路交通建设工地视频监控数据 市交通质监站\n 水路交通建设企业信用数据 \n 水路交通工程造价管理数据 \n 水路交通工程监理管理数据 \n\n(三)船检业务库升级\n1.升级我省的二级船检业务库\n交通运输部海事局船舶检验管理系统（以下简称部局系统）将增加渔船船用产品检验发证模块，并调整相关的数据结构。我省的二级船检业务库若要继续接收部局系统数据，则需进行升级，以保持与部局系统的最新数据结构一致，保证数据交换的准确性、完整性、及时性。', 'gnmk':

'aqxq': '数据安全策略\n防攻击\n为有效抵御外部攻击对数据的侵害，在原有安全保障体系基础上，开展进一步的数据安全方案设计与落实，分别从网络区域划分、业务系统自身安全设计、加密技术应用以及灾备体系设计等方面进行强化。\n1.独立的数据库区域\n在网络上划分独立的数据库区，用于保存业务系统必须的生产数据，非生产必须的历史数据禁止保存在该区域。仅允许应用服务区访问数据库区，并根据业务需求设置严格的端口及访问控制策略，其他区域禁止直接访问数据库区。\n2.针对业务系统的安全要求\n本项目在开发生命周期过程中始终贯彻安全规则，通过在软件开发生命周期的每个阶段执行必要的安全控制或任务，采取预防、检测和监控相结合的方式，提高应用系统安全性的同时，确保应用系统符合信息系统安全等级保护第三级的要求。具体流程如下：\n在需求分析阶段，把安全需求分析作为整个软件需求分析的一部分，同时在满足基本安全需求基础上，对应用系统进行威胁评估，进一步明确安全需求；\n在设计阶段，对系统进行安全架构设计和安全功能设计，应用系统的安全设计需经过安全审核后才能进行到下一个阶段工作；\n在开发阶段，在遵循统一的安全编码规范的同时，对内应采取安全审核措施，对外应引入第三方安全审核机制；\n在测试阶段，除了对功能和性能测试外，还对应用系统自身的安全性进行全面测试；\n在部署阶段，对应用系统的部署环境进行安全审核，确保不因部署环境问题引入新的安全风险；同时，系统上线前还引入第三方安全评估。\n3.加密技术应用\n为确保数据传输与存储过程中的机密性、完整性不被破坏，在终端与应用之间链路加密传输及关键业务数据存储加密等环节，通过加密技术进行了数据安全保障。\n4.灾备体系\n为确保数据能够在所要求的时限内及时恢复，保障业务系统的持续运营，可考虑在以后采用二地三中心的模式建立同城灾备和异地灾备体系，并根据业务实时性要求，设计灾备级别及相应灾备策略。\n防泄密\n为防止内部人员有意或无意的失泄密事件发生，在原安全保障体系的基础上，强化内部人员的安全管控能力，针对失泄密的防范，分别从管理和技术两方面进行了补充。\n在管理上，通过针对失泄密可能发生的环节，细化了一系列安全管理制度，包括人员安全管理、安全意识培训、办公环境、介质管理、资产管理等内容，以此强化内部安全管理，降低失泄密风险；\n在技术上，通过部署终端安全管理软件，实现对重点设备的安全管控与行为审计；部署防病毒设备，实现对全网恶意代码的检测与查杀；部署磁盘信息擦除设备，实现对报废存储设备上敏感信息的清除。\n防越权\n为防止内部用户越权访问，在原有安全保障体系的基础上，通过在管理上实现更严格的人员权限管理，在技术上，部署运维审计以及更进一步的细分权限配置，实现对越权事件的有效控制。\n在管理层面，制定相关制度，明确要求人员在调岗/离岗时，必须注销系统内原身份与权限。\n在技术层面，为强化各层面的认证与权限管理，细分数据库管理员权限，确保数据库系统管理员与业务数据管理员分开；实现了用户身份双因素认证，强化了身份认证与审计管理。在业务系统上线前，还通过了基于权限的攻击行为与漏洞检测，确保系统身份认证与权限控制的健壮性与有效性。\n可审计\n为确保事后可追查，应对外部攻击、内部泄密以及权限滥用的行为进行全面的安全审计。针对攻击行为，通过部署基于攻击行为模型的安全设备，实现对攻击行为的安全检测；针对应用系统，建立自身完整有效的强制审计机制；针对数据库，通过数据库日志与第三方审计结合的方式，实现对数据库操作的全面审计，禁止绕过第三方审计系统对数据库进行操作；针对网络环境，通过部署网络行为审计、分析设备，实现全面审计与综合分析。',

'aqxq': '数据安全策略\n防攻击\n为有效抵御外部攻击对数据的侵害，在原有安全保障体系基础上，开展进一步的数据安全方案设计与落实，分别从网络区域划分、业务系统自身安全设计、加密技术应用以及灾备体系设计等方面进行强化。\n1.独立的数据库区域\n在网络上划分独立的数据库区，用于保存业务系统必须的生产数据，非生产必须的历史数据禁止保存在该区域。仅允许应用服务区访问数据库区，并根据业务需求设置严格的端口及访问控制策略，其他区域禁止直接访问数据库区。\n2.针对业务系统的安全要求\n本项目在开发生命周期过程中始终贯彻安全规则，通过在软件开发生命周期的每个阶段执行必要的安全控制或任务，采取预防、检测和监控相结合的方式，提高应用系统安全性的同时，确保应用系统符合信息系统安全等级保护第三级的要求。具体流程如下：\n在需求分析阶段，把安全需求分析作为整个软件需求分析的一部分，同时在满足基本安全需求基础上，对应用系统进行威胁评估，进一步明确安全需求；\n在设计阶段，对系统进行安全架构设计和安全功能设计，应用系统的安全设计需经过安全审核后才能进行到下一个阶段工作；\n在开发阶段，在遵循统一的安全编码规范的同时，对内应采取安全审核措施，对外应引入第三方安全审核机制；\n在测试阶段，除了对功能和性能测试外，还对应用系统自身的安全性进行全面测试；\n在部署阶段，对应用系统的部署环境进行安全审核，确保不因部署环境问题引入新的安全风险；同时，系统上线前还引入第三方安全评估。\n3.加密技术应用\n为确保数据传输与存储过程中的机密性、完整性不被破坏，在终端与应用之间链路加密传输及关键业务数据存储加密等环节，通过加密技术进行了数据安全保障。\n4.灾备体系\n为确保数据能够在所要求的时限内及时恢复，保障业务系统的持续运营，可考虑在以后采用二地三中心的模式建立同城灾备和异地灾备体系，并根据业务实时性要求，设计灾备级别及相应灾备策略。\n防泄密\n为防止内部人员有意或无意的失泄密事件发生，在原安全保障体系的基础上，强化内部人员的安全管控能力，针对失泄密的防范，分别从管理和技术两方面进行了补充。\n在管理上，通过针对失泄密可能发生的环节，细化了一系列安全管理制度，包括人员安全管理、安全意识培训、办公环境、介质管理、资产管理等内容，以此强化内部安全管理，降低失泄密风险；\n在技术上，通过部署终端安全管理软件，实现对重点设备的安全管控与行为审计；部署防病毒设备，实现对全网恶意代码的检测与查杀；部署磁盘信息擦除设备，实现对报废存储设备上敏感信息的清除。\n防越权\n为防止内部用户越权访问，在原有安全保障体系的基础上，通过在管理上实现更严格的人员权限管理，在技术上，部署运维审计以及更进一步的细分权限配置，实现对越权事件的有效控制。\n在管理层面，制定相关制度，明确要求人员在调岗/离岗时，必须注销系统内原身份与权限。\n在技术层面，为强化各层面的认证与权限管理，细分数据库管理员权限，确保数据库系统管理员与业务数据管理员分开；实现了用户身份双因素认证，强化了身份认证与审计管理。在业务系统上线前，还通过了基于权限的攻击行为与漏洞检测，确保系统身份认证与权限控制的健壮性与有效性。\n可审计\n为确保事后可追查，应对外部攻击、内部泄密以及权限滥用的行为进行全面的安全审计。针对攻击行为，通过部署基于攻击行为模型的安全设备，实现对攻击行为的安全检测；针对应用系统，建立自身完整有效的强制审计机制；针对数据库，通过数据库日志与第三方审计结合的方式，实现对数据库操作的全面审计，禁止绕过第三方审计系统对数据库进行操作；针对网络环境，通过部署网络行为审计、分析设备，实现全面审计与综合分析。',
