sonicwall简介

1.网络安全概述1.1网络安全简述随着政府上网、海关上网、企业上网、电子商务、网上娱乐等一系列网络应用的蓬勃发展，Internet正在越来越多地离开原来单纯的学术环境，融入到社会的各个方面。

一方面，网络用户成分越来越多样化，出于各种目的的网络入侵和攻击越来越频繁；另一方面，网络应用越来越深地渗透到金融、商务、国防等等关键要害领域。

换言之，Internet网的安全，包括网上的信息数据安全和网络设备服务的运行安全，日益成为与国家、政府、企业、个人的利益休戚相关的"大事情"。

然而，由于在早期网络协议设计上对安全问题的忽视，以及在使用和管理的无政府状态，逐渐使Internet自身的安全受到严重威胁，与它有关的安全事故屡有发生。

这就要求我们对与Internet互连所带来的安全性问题予以足够重视。

网络面临的安全威胁大体可分为两种：一是对网络数据的威胁；二是对网络设备的威胁。

这些威胁可能来源于各种各样的因素：可能是有意的，也可能是无意的；可能是来源于企业外部的，也可能是内部人员造成的；可能是人为的，也可能是自然力造成的。

总结起来，大致有下面几种主要威胁：(1) 非人为、自然力造成的数据丢失、设备失效、线路阻断(2) 人为但属于操作人员无意的失误造成的数据丢失(3) 来自外部和内部人员的恶意攻击和入侵前面两种的预防与传统电信网络基本相同（略）。

最后一种是当前Internet网络所面临的最大威胁，是电子商务、政府上网工程等顺利发展的最大障碍，也是企业网络安全策略最需要解决的问题。

1.2防火墙防火墙是设置在被保护网络和外部网络之间的一道屏障，以防止发生不可预测的、潜在破坏性的侵入。

防火墙是指设置在不同网络或网络信任域与非信任域之间的一系列功能部件的组合。

通过制订安全策略，它可通过监测、限制、更改跨越防火墙的数据流，尽可能地对外部屏蔽网络内部的信息、结构和运行状况，以此来实现网络的安全保护。

防火墙是一个分离器，一个限制器，一个分析器，有效地监控了内部网和Internet之间的任何活动，保证了内部网络的安全。

CD随身听历史

1982年8月31日傍晚，SONY．CBS／SONY．荷兰飞利浦与POLYGRAM四家公司共同举办了CD这个数字录音格式的发布会，并决定从秋季起开始在日本发售。

直径仅仅12cm，记录无损失的数字讯号，非线性播放，也就是说自由的快速选曲。

能够半永久的使用，CD实现了许多乐迷的梦想。

并且索尼公司在1982年10月1日推出了第一台CD机CDP-101，售价接近17万日元，对一般消费者而言是很难接受的。

进入1983年后，其他公司的CD机也相继上市，销售形势一片大好。

但是，接下来的一短时间的销售停滞下来了，原来，当时购买CD系统的人是以Hi-Fi发烧友为主，大部分人依旧偏好已融入生活的LP。

在美国也是VHS 录像卡带一枝独秀，人们找不到理由将他换掉。

为了拯救这种颓势，索尼公司音响事业部的大曾根幸三带领属下开发了约4张CD盒厚度的产品D-50，这就是现代便携式CD播放器的鼻祖。

SONY篇（1984D-50------1999D-Ej915）80年代的DISCMAN普遍具备不输给低档CD台式机的音质和强大的耳机输出功率，而在便携性和省电性能上的缺陷则是致命的。

目前在各地的二手货市场里仍然有相当少部分这些超级古董出售，他们已经成为收藏者猎取的目标和HIFI耳机玩家里学生一族的最爱。

1984/11/01推出D-50售价49800日元。

127×36.9×132.5mm。

30mw。

颜色有红、黑两种。

用一个硕大无朋的电池盒供电，拥有除遥控和重复播放功能之外的所有CDP-101的功能。

早期的DISCMAN由于体积太大，配有专用的背带以外出时携带，自D-50开始沿用了5-6年时间。

D-50和SONY有源音箱的搭配居然成为了当时红极一时的小型CD播放器材组合。

从发售初始在一路低迷的CD 播放机市场上它的销售状况就超乎预料的好。

D-50之后的小型CD播放机被索尼命名为Discman，目前称之为CD Walkman。

索尼CD随⾝听历史上最经典的5个型号索尼CD随⾝听历史上最经典的5个型号索尼⼀直是CD随⾝听的⾏业霸主，⽽其辉煌的CD随⾝听历史不可磨灭，虽然如今CD随⾝听已经不再风⾏，但不可否认CD随⾝听曾经在便携设备中不可动摇的历史地位，作为CD随⾝听爱好者，我们需要不时地进⾏⼀下缅怀，今天我们要拿出来晒晒太阳的是索尼CD随⾝听历史上最经典的5个型号，当然这是笔者多年玩机的⼀个感受和见解，如果不能代表你的看法，请君⾃选，名分这种东西很虚的，连3岁的⼩孩都懂的。

2012年的今天，国美苏宁这样的超级电器连锁店都罕见CD随⾝听，笔者逛下来，在苏宁上海门店还能看到的只有索尼SONY家D-NE830还有D-NE20这两款末代CD随⾝听。

想当年，CD随⾝听留下的不仅仅是他的便携性，还有我们所要追求的美好东西：唯美的⾳质，对⾳乐美好的追求。

今天我们我们把那些曾经为CD随⾝听⽴下汗马功劳的CD随⾝听型号选中5个代表性⽐较强的机型和⼤家共同回忆，本编只针对索尼型号，其他品牌下次有空再⼀⼀回忆。

====================================================第⼀个登场的索尼CD随⾝听是：D-50索尼公司于1984年11⽉1⽇发布了D-50。

这给⼀路低迷CD播放机市场打了⼀针强⼼剂，销路超乎预料的好，D-50和⼀款SONY有源⾳箱的搭配居然成为了当时红极⼀时的⼩型CD播放器材组合。

与此同时SONY公司只⽤了⼀年半时间就成功降价低了⽣产成本开始赢利，不仅如此，报价相对低廉D-50让各家⼚商也纷纷降价低CD Player报价。

再加上CD软件进⼀步普及，CD录⾳格式终于进⼊了正规发展轨道，D-50之后⼩型CD播放机被定位同于随⾝听等级因此便将它命名为“Discman”⽬前称之为CD Walkman。

D-50的体积为：127×36.9×132.5mm，⽿机插⼝输出功率⼤约30MW。

SonicWall NSA系列网络安全应用机产品说明说明书

The SonicWall Network Security Appliance (NSA) series providesmid-sized networks, branch offices and distributed enterprises with advanced threat prevention in a high-performance security platform. Combining next-generation firewall technology withour patented* Reassembly-Free Deep Packet Inspection (RFDPI) engine on a multi-core architecture, the NSA series offers the security, performance and control organizations require. Superior threat prevention and performanceNSA series next-generation firewalls (NGFWs) integrate advanced security technologies to deliver superior threat prevention. Our patented single-pass RFDPI threat prevention engine examines every byte of every packet, inspecting both inbound and outbound traffic simultaneously. The NSA series leverages on-box capabilities including intrusion prevention, anti-malware and web/URL filtering in addition to cloud-based SonicWall Capture multi-engine sandboxing service to block zero-day threats at the gateway. Unlike other security products that cannot inspect large files for hidden threats, NSA firewalls scan files of any size acrossall ports and protocols. The security architecture in SonicWall NGFWs has been validated as one of the industry’s best for security effectiveness by NSS Labs for five consecutive years. Further, SonicWall NGFWs provide complete protection by performingfull decryption and inspection of TLS/SSL and SSH encrypted connections as well as non-proxyable applications regardless of transport or protocol. The firewall looks deep inside every packet (the header and data) searching for protocol non-compliance, threats, zero-days, intrusions, and even defined criteria to detect and prevent hidden attacks that leverage cryptography, block encrypted malware downloads, cease the spread of infections, and thwart command and control (C&C) communications and data exfiltration. Inclusion and exclusion rules allow total control to customize which traffic is subjected to decryption and inspection based on specific organizational compliance and/or legal requirements. When organizations activate deep packet inspection functions such as intrusion prevention, anti-virus, anti-spyware, TLS/SSL decryption/inspection and others on their firewalls, network performance often slows down, sometimes dramatically. NSA series firewalls, however, feature a multi-core hardware architecture that utilizes specialized security microprocessors. Combined with our RFDPI engine,this unique design eliminates the performance degradation networks experience with other firewalls.In today’s security environment, it’s not enough to rely on solely on outside parties for threat information. That’s why SonicWall formed its own in-house Capture Labs threat research team more than 15 years ago. This dedicated team gathers, analyzes and vets data from over one million sensors in itsSonicWall Network SecurityAppliance (NSA) seriesIndustry-validated security effectiveness and performance formid-sized networksBenefits:Superior threat preventionand performance• Patented reassembly-free deeppacket inspection technology• On-box and cloud-based threatprevention• TLS/SSL decryption and inspection• Industry-validated securityeffectiveness• Multi-core hardware architecture• Dedicated Capture Labs threatresearch teamNetwork control and flexibility• Powerful SonicOS operating system• Application intelligence and control• Network segmentation with VLANs• High-speed wireless securityEasy deployment, setup andongoing management• Tightly integrated solution• Centralized management• Scalability through multiplehardware platforms• Low total cost of ownershipCapture Threat Network. SonicWall also participates in industry collaboration efforts and engages with threat research communities to gather and share samples of attacks and vulnerabilities. This shared threat intelligence is usedto develop real-time countermeasures that are automatically deployed to our customers’ firewalls.Network control and flexibilityAt the core of the NSA series is SonicOS, SonicWall’s feature-rich operating system. SonicOS provides organizations with the network control and flexibility they require through application intelligence and control, real-time visualization, an intrusion prevention system (IPS) featuring sophisticated anti-evasion technology, high-speed virtual private networking (VPN) and other robust security features.Using application intelligence and control, network administrators can identify and categorize productive applications from those that are unproductive or potentially dangerous, and control that traffic through powerful application-level policies on both a per-user and a per-group basis (along with schedules and exception lists). Business-critical applications can be prioritizedand allocated more bandwidthwhile non-essential applications arebandwidth-limited. Real-time monitoringand visualization provides a graphicalrepresentation of applications, users andbandwidth usage for granular insightinto traffic across the network.For organizations requiring advancedflexibility in their network design,SonicOS offers the tools to segmentthe network through the use of virtualLANs (VLANs). This enables networkadministrators to create a virtualLAN interface that allows for networkseparation into one or more logicalgroups. Administrators create rules thatdetermine the level of communicationwith devices on other VLANs.Built into every NSA series firewall is awireless access controller that enablesorganizations to extend the networkperimeter securely through the use ofwireless technology. Together, SonicWallfirewalls and SonicWave 802.11ac Wave2 wireless access points create a wirelessnetwork security solution that combinesindustry-leading next-generation firewalltechnology with high-speed wireless forenterprise-class network security andperformance across the wireless network.Easy deployment, setup andongoing managementLike all SonicWall firewalls, the NSAseries tightly integrates key security,connectivity and flexibility technologiesinto a single, comprehensive solution.This includes SonicWave wirelessaccess points and the SonicWall WANAcceleration Appliance (WXA) series,both of which are automatically detectedand provisioned by the managingNSA firewall. Consolidating multiplecapabilities eliminates the need topurchase and install point products thatdon’t always work well together. Thisreduces the effort it takes to deploy thesolution into the network and configureit, saving both time and money.Ongoing management and monitoringof network security are handled centrallythrough the firewall or through theSonicWall Global Management System(GMS), providing network administratorswith a single pane of glass from whichto manage all aspects of the network.Together, the simplified deploymentand setup along with the ease ofmanagement enable organizations tolower their total cost of ownership andrealize a high return on investment.SonicWallSonicWave 432iSonicWall NSA 5600The SonicWall NSA 2600 is designed to address the needs of growing small organizations, branch offices and school campuses.The SonicWall NSA 3600 is ideal for branch office and small- to medium-sized corporate environments concerned aboutthroughput capacity and performance.Dual fansPower8 x 1GbEports1GbEmanagementConsoleDualDual fansPower2 x 10GbE12 x 1GbE1GbEmanagement4 x 1GbESFP portsConsoleDualDual fansPower2 x 10GbE 12 x 1GbE1GbEmanagement 4 x 1GbESFP portsConsoleDual The SonicWall NSA 4600 secures growing medium-sizedorganizations and branch office locations with enterprise-class features and uncompromising performance.The SonicWall NSA 5600 is ideal for distributed, branch office and corporate environments needingsignificant throughput.Dual fansPower2 x 10GbE12 x 1GbE 1GbEmanagement4 x 1GbE SPF portsConsole DualNetwork Security Appliance 6600The SonicWall NSA 6600 is ideal for large distributed andcorporate central site environments requiring high throughputcapacity and performance.Dual hotswappable fansPower4 x 10GbE8 x 1GbE 1GbEmanagement 8 x 1GbE SFP ports ConsoleDualReassembly-Free Deep Packet Inspection engineThe SonicWall Reassembly-Free Deep Packet Inspection (RFDPI) is a single-pass, low latency inspection system that performs stream-based, bi-directional traffic analysis at high speed without proxying or buffering to effectivelyuncover intrusion attempts and malwaredownloads while identifying application traffic regardless of port and protocol. This proprietary engine relies onstreaming traffic payload inspection to detect threats at Layers 3-7, and takesnetwork streams through extensive andrepeated normalization and decryption in order to neutralize advanced evasion techniques that seek to confusedetection engines and sneak malicious code into the network.Once a packet undergoes thenecessary pre-processing, including SSL decryption, it is analyzedagainst a single, proprietary memory representation of three signature databases: intrusion attacks, malware and applications. The connection state is then advanced to represent the positionof the stream relative to these databases until it encounters a state of attack, or other “match” event, at which point a pre-set action is taken.In most cases, the connection is terminated and proper logging andnotification events are created. However, the engine can also be configured for inspection only or, in case of application detection, to provide Layer 7 bandwidth management services for the remainder of the application stream as soon as the application is identified.Flexible, customizable deployment options – NSA series at-a-glanceEvery SonicWall NSA firewall utilizes a breakthrough, multi-core hardware design and RFDPI for internal and external network protection without compromising network performance. NSA series NGFWs combine high-speed intrusion prevention, file and content inspection, and powerful application intelligence and control with anextensive array of advanced networking and flexible configuration features.

The team gathers data on potential threats from several sources including our award-winning network sandboxing service, Capture Advanced Threat Protection, as well as more than 1 million SonicWall sensors located around the globe that monitor traffic for emerging threats. Itis analyzed via machine learning using SonicWall's Deep Learning Algorithmsto extract the DNA from the code to see if it is related to any known forms of malicious code.SonicWall NGFW customers benefit from continuously updated threat protection around the clock. New updates take effect immediately without reboots or interruptions. The signatures resident on the appliances are designed to protect against wide classes of attacks, covering tens of thousands of individual threats with a single signature.In addition to the countermeasureson the appliance, NSA appliances alsohave access to SonicWall CloudAV,which extends the onboard signatureintelligence with over 20 millionsignatures. This CloudAV database isaccessed by the firewall via a proprietary,light-weight protocol to augment theinspection done on the appliance. WithCapture Advanced Threat Protection,a cloud-based multi-engine sandbox,organizations can examine suspiciousfiles and code in an isolated environmentto stop advanced threats such as zero-day attacks.Advanced threat protection SonicWall Capture Advanced Threat Protection Service is a cloud-based multi-engine sandbox that extends firewall threat protection to detect and prevent zero-day threats. Suspicious files are sent to the cloud for analysis with the option to hold them at the gateway until a verdict is determined. Themulti-engine sandbox platform, which includes virtualized sandboxing, full system emulation and hypervisor level analysis technology, executes suspicious code and analyzes behavior. When afile is identified as malicious, a hash is immediately created within Capture and later a signature is sent to firewalls to prevent follow-on attacks.The service analyzes a broad rangeof operating systems and file types, including executable programs, DLL, PDFs, MS Office documents, archives, JAR and APK.Capture provides an at-a-glance threatanalysis dashboard and reports, whichdetail the analysis results for files sent tothe service, including source, destinationand a summary plus details of malwareaction once detonated.ProtectionCollectionClassiﬁcationCountermeasureL A B SGlobal management and reporting For highly regulated organizations wanting to achieve a fully coordinated security governance, compliance and risk management strategy, SonicWall Global Management System (GMS®) provides administrators a unified, secure and extensible platform to manage SonicWall firewalls, wireless access points and Dell X-Series switches through a correlated and auditable workstream process.

但是这个庞大的网络及其相关的技术为不断增长的安全威胁提供了可乘之机，因而企业必须学会保护自己免受这些威胁的危害。

在捍卫网络安全的过程中，防火墙受到人们越来越多的青睐。

作为一种提供信息安全服务、实现网络和信息安全的基础设施，防火墙采用将内部网和公众网如Internet分开的方法，可以作为不同网络或网络安全域之间信息的出入口，根据企业的安全策略控制出入网络的信息流。

再加上防火墙本身具有较强的抗攻击能力，能有效地监控内部网和Internet之间的任何活动，从而为内部网络的安全提供了有力的保证。

1.1 XX公司网络现状分析：随着技术的发展，各种入侵和攻击从针对TCP/IP协议本身弱点的攻击转向针对特定系统和应用漏洞的攻击，如针对Windows系统和Oracle/SQL Server等数据库的攻击，这些攻击和入侵手段封装在TCP/IP协议的净荷部分。

传统的UTM设备如第一代的包过滤UTM，第二代的应用代理UTM到第三代的全状态检测UTM对此类攻击无能为力，因为它们只查TCP/IP协议包头部分而不检查数据包的内容。

此外基于网络传播的病毒及间谍软件也给互联网用户造成巨大的损失。

同时层出不穷的即时消息和对等应用如MSN，QQ，BT等也带来很多安全威胁并降低员工的工作效率。

如今的安全威胁已经发展成一个混合型的安全威胁，传统的防火墙设备已经不能满足客户的安全需求。

1.2 XX公司网络简述：XX公司现有的网络属于紧缩核心层结构，通过核心交换机进行快速转发，与接入层交换机实现全网畅通，通过一台路由器与外网互连。
