shape using QoS).User-ID: Enabling Applications by Users and GroupsTraditionally, security policies were applied based on IP addresses, but the increasingly dynamic nature of users and computing means that IP addresses alone have become ineffective as a mechanism for monitoring and controlling user activity. User-ID allows organizations to extend user- or group-based application enablement polices across Microsoft Windows, Apple Mac OS X, Apple iOS, and Linux users.Many of today’s applications provide significant benefit, but are also being used as a delivery tool for modern malware and threats. Content-ID, in conjunction with App-ID, provides administrators with a two-pronged solution to protecting the network. After App-ID is used to identify and block unwanted applications, administrators can then securely enable allowed applications by blocking vulnerability exploits, modern malware, viruses, botnets, and other malware from propagating across the network, all regardless of port, protocol, or method of evasion. Rounding out the control elements that Content-ID offers is a comprehensive URL database to control web surfing and data filtering features.Application Protocol Detection / Decryption Application ProtocolDecoding Application SignatureHeuristicsDATACC # SSN FilesVulnerability ExploitsViruses SpywareContent-IDURLSWeb FilteringTHREATS10.0.0.21710.0.0.22010.0.0.23210.0.0.24210.0.0.24510.0.0.22710.0.0.23910.0.0.22110.0.0.23210.0.0.21110.0.0.209User-IDEnd Station Polling Captive PortalLogin Monitoring Role DiscoveryFinance GroupNancy I MarketingSteve I FinancePaul I EngineeringApplication Visibility View application activity in a clear , easy-to-read format. Add and remove filters to learn more about the application, its functions and who is using them.Secure Application EnablementThe seamless integration of App-ID, User-ID, and Content-ID enables organizations to establish consistent application enablement policies, down to the application function level in many cases, that go far beyond basic allow or deny. With GlobalProtect™, the same policies that protect users within the corporate headquarters are extended to all users, no matter where they are located, thereby establishing a logical perimeter for users outside of the network.Secure enablement policies begin with App-ID determining the application identity, which is then mapped to the associated user with User-ID, while traffic content is scanned for threats, files, data patterns, and web activity by Content-ID. These results are displayed in Application Command Center (ACC) where the administrator can learn, in near real-time, what is happening on the network. Then, in the policy-editor, the information viewed in ACC about applications, users, and content can be turned into appropriate security policies that block unwanted applications, while allowing and enabling others in a secure manner. Finally, any detailed analysis, reporting, or forensics can be performed, again, with applications, users, and content as the basis.Application Command Center: Knowledge is PowerApplication Command Center (ACC) graphically summarizes the log database to highlight the applications traversing the network, who is using them, and their potential security impact. ACC is dynamically updated, using the continuous traffic classification that App-ID performs; if an application changes ports or behavior , App-ID continues to see the traffic, displaying the results in ACC. New or unfamiliar applications that appear in ACC can be quickly investigated with a single click that displays a description of the application, its key features, its behavioral characteristics, and who is using it.Additional visibility into URL categories, threats, and data provides a complete and well-rounded picture of network activity. With ACC, an administrator can very quickly learn more about the traffic traversing the network and then translate that information into a more informed security policy.Policy Editor: Translating Knowledge into Secure Enablement PoliciesThe knowledge of which applications are traversing the network, who is using them, and what the potential security risks are, empowers administrators to quickly deploy application-, application function-, and port-based enablement policies in a systematic and controlled manner. Policy responses can range from open (allow), to moderate (enabling certain applications or functions, then scan, or shape, schedule, etc.), to closed (deny). Examples may include:• Protect an Oracle database by limiting access to finance groups, forcing the traffic across the standard ports, and inspecting the traffic for application vulnerabilities.• Enable only the IT group to use a fixed set of remote management applications (e.g., SSH, RDP , Telnet) across their standard ports. • Define and enforce a corporate policy that allows and inspects specific webmail and instant messaging usage but blocks their respective file transfer functions.• Allow Microsoft SharePoint Administration to be used by only the administration team, and allow access to Microsoft SharePoint Documents for all other users. • Deploy web enablement policies that that allow and scan traffic to business related web sites while blocking access to obvious non-work related web sites and “coaching” access to others through customized block pages.Unified Policy EditorA familiar look and feel enables the rapid creation and deployment of policies that control applications,users and content.• Implement QoS policies to allow the use of both bandwidth-intensive media applications and websites but limit their impact on VoIP applications.• Decrypt SSL traffic to social networking and webmail sites and scan for malware and exploits.• Allow downloads of executable files from uncategorized websites only after user acknowledgement to prevent drive-by-downloads via zero-day exploits.• Deny all traffic from specific countries or block unwanted applications such as P2P file sharing, circumventors, and external proxies.The tight integration of application control, based on users and groups, and the ability to scan the allowed traffic for a wide range of threats, allows organizations to dramatically reduce the number of policies they are deploying along with the number of employee adds, moves, and changes that may occur on a day-to-day basis.Policy Editor: Protecting Enabled Applications Securely enabling applications means allowing access to the applications, then applying specific threat prevention and file, data, or URL filtering policies. Each of the elements included in Content-ID can be configured on a per-application basis.• Intrusion Prevention System (IPS): Vulnerability protection integrates a rich set of intrusion prevention system (IPS) features to block network and application-layer vulnerabil-ity exploits, buffer overflows, DoS attacks, and port scans. • Network Antivirus: Stream-based antivirus protec-tion blocks millions of malware variants, including PDF viruses and malware hidden within compressed files or web traffic (compressed HTTP/HTTPS). Policy-based SSL decryption enables organizations to protect against malware moving across SSL encrypted applications.• URL Filtering: A fully-integrated, customizable URL filtering database allows administrators to apply granular web-browsing policies, complementing application visibility and control policies and safeguarding the enterprise from a full spectrum of legal, regulatory, and productivity risks. • File and Data Filtering: Data filtering features enable administrators to implement policies that will reduce the risks associated with file and data transfers. File transfers and downloads can be controlled by looking inside the file (as opposed to looking only at the file extension), to determine if it should be allowed or not. Executable files, typically found in drive-by downloads, can be blocked, thereby protecting the network from unseen malware propagation. Finally, data filtering features can detect, and control the flow of confidential data patterns (credit card and social security numbers).Content and Threat Visibility View URL, threat and file/data transfer activity in a clear, easy-to-read format. Add and remove filters to learn more aboutindividual elements.Modern Malware Detection and PreventionMalware has evolved to become an extensible networked application that provides attackers with unprecedented access and control inside of the targeted network. As the power of modern malware increases, it is critical that enterprises be able to detect these threats immediately, even before the threat has a defined signature. Palo Alto Networks next-generation firewalls provide organizations with a multi-faceted approach based on the direct analysisof both executable files and network traffic to protect their networks even before signatures are available.• WildFire™: Using a cloud-based approach, WildFire exposes previously unseen malicious executable files by directly observing their behavior in a secure virtualized environment. WildFire looks for malicious actions within Microsoft Windows executable files such as changing registry values or operating system files, disabling security mechanisms, or injecting code into running processes. This direct analysis quickly and accurately identifies malware even when no protection mechanism is available. The results are immediately delivered to the administrator for an appropriate response and a signature is automatically developed and delivered to all customers in the next available content update. • Behavioral Botnet Detection: App-ID classifies all traffic at the application level, thereby exposing any unknown traffic on the network, which is often an indication of malware or other threat activity. The behavioral botnet report analyzes network behavior that is indicative of a botnet infection such as repeatedly visiting malware sites, using dynamic DNS, IRC, and other potentially suspicious behaviors. The results are displayed in the form of a list of potentially infected hosts that can be investigated as possible members of a botnet.Traffic Monitoring: Analysis, Reporting and Forensics Security best practices dictate that administrators strike a balance between being proactive, continually learning and adapting to protect the corporate assets, and being reactive, investigating, analyzing, and reporting on security incidents. ACC and the policy editor can be used to proactively apply application enablement policies, while a rich set of monitoring and reporting tools provide organizations with the necessary means to analyze and report on the application, users and content flowing through the Palo Alto Networks next-generation firewall.• App-Scope: Complementing the real-time view of applica-tions and content provided by ACC, App-scope provides a dynamic, user-customizable view of application, traffic, and threat activity over time.• Reporting: Predefined reports can be used as-is, customized, or grouped together as one report in order to suit the specific requirements. All reports can be exported to CSV or PDF format and can be executed and emailed on a scheduled basis.• Logging: Real-time log filtering facilitates rapid forensic investigation into every session traversing the network. Log filter results can be exported to a CSV file or sent to a syslog server for offline archival or additional analysis.• Trace Session Tool: Accelerate forensics or incident investigation with a centralized correlated view acrossall of the logs for traffic, threats, URLs, and applications related to an individual session.。

在vmware虚拟机中安装Paloalto下一代防火墙NGFW(英文)
Installing the PA 100 VM in VMware Workstation 9.xJohan Loosjohan@accessdenied.beVersion 1.0IntroductionThe PA 100-VM is a virtual firewall delivered as a VMware OVF. This is a way to package and distribute virtual machines. This file contains all the files needed to run your file into a virtual environment.I’m not running a VMware ESXi in my environment, butI have a VMware workstation 9.x on Windows 7 64-bit. When you buy a virtual instance of the firewall, you receive theauthorization codes from your reseller. When you import the files into VMware workstation,two cores are reserved, 4 GB of RAM and two network adapters.PA-VM2CPU4 GBNIC 340 GB NIC2NIC 1The first network adapter is used for management, the second network adapter is used as ethernet1/1 and the third network adapter is used as ethernet1/2. Additional network adapters can be added and are used as Ethernet interfaces by the firewall. It is important that these network adapters support vmxnet3. The can be verified in the virtual machine configuration file (.vmx). The following steps describe how to install the VM and configure your management access.Obtaining the bits task list❒Logon into the portal page on Palo Alto Networks❒Register your device❒Download and extract the source package❒Import your VM firewall into VMware workstation❒Configuring the management interface❒Register your firewall❒Update your device❒Clone a licensed device❒Managing the deviceLogon into the portal page on Palo Alto NetworksLogin with your username and password that you’ve used during registrat ionRegister the deviceUnder Manage Devices, select My VM-Series Auth-CodesClick on Add VM-Series Auth-CodeIn the Auth Code text box, type the Authentication Code that you’ve received from your resellerDownload and extract the source packageClick on Download link to download the packageAfter downloading the source package, the file phoenix-5.0.zip file is available Extract this zip file to a temporary locationImport your VM firewall into VMware workstationStart VMware WorkstationFrom the Menu, select File, Open and browse to your temporary locationType a name for your virtual machine (PAN100VM), specify a storage location and click ImportAfter you’ve imported the virtual machine, you can add additional network adapter to your virtual firewall. In my configuration, I’ve added an additionalnetwork adapter as you can see in following figureAfter adding additional network adapters, be sure that these network adapters are configured using vmxnet3. Browse to the location of your virtual firewall andopen the Virtual Machine Configuration file (PANVM100.vmx) as you can see inthe following figure:The network adapters are configured as follow:Configure the Management interfaceLaunch VMware Workstation and start the virtual machine PANVM100Logon into your VMAfter login, type Configure and press EnterIn Edit configuration mode, configure the management interface as in following figureType CommitRegister your firewallLogon to the Palo Alto websiteUnder Manage Devices, select VM-Series Auth-CodesSelect Register VM, type the UUID and CPUID. These values can be found in the Web UI | Dashboard | General Information and click on RegisterAfter adding the above information click on ActivateType the Authorization Code and click ActivateAfter successful activation, the following information is availableDownload the PA-VM license file and import this file into your PA VM under Device | Licenses | UploadThe management interface contact the updates server and download the updatesUpgrade your deviceThe device can be upgraded via a file or via the web UI.Clone a licensed deviceTwo identifiers are used for each instance of the VM firewall. The Universally Unique ID (UUID) and the CPU ID. The UUID is dedicated to each virtual machine and the CPU ID is not unique since it belongs to the host CPU.When you clone the VM, the UUID will change and the license is not valid anymore. The reason is that the license is bound to the UUID/serial number of the firewall. You cannot run two virtual machines with the same UUID.Managing the deviceYour firewall can be managed via a web browser. Configure a client computer within the same address range as the management interface. Open a web browser and login into the management UI.。

解决了网络复杂结构，具有强大的应用识别、威胁防范、用户识别控制、优越的性能和高中低端设备选择。
数据包处理流程图：2.查看会话可以通过查看会话是否创建以及会话详细信息来确定报文是否正常通过防火墙，如果会话已经建立，并且一直有后续报文命中刷新,基本可以排除防火墙的问题。
2.1.查看会话汇总命令：show session info举例：admin@PA-VM> show session info说明：通过以上命令可以查看到设备支持会话数的最大值，从而检查是否有负载的情况发生。
2.2.查看session ID命令：show session id XX举例：说明：从以上命令中可以看出到底是否存在非法流量，可以通过检查源地址和目的地址端口等信息2.3.条件选择查看会话命令：show session all filter source[ip]destination[ip] application[app]举例：说明：可以检查一些风险会话2.4.查看当前并发会话数命令：show session info举例：当前并发会话13个，而最大会话为262138，说明会话利用率并不高，最后一条红色标记为新建数值。
说明：了解设备当前并发会话情况2.5.会话过多处理方法命令：1、show session all（检查所有session）2、show session id XX（检查该session是否不法流量）说明：如果发现会话数大于设备可支撑的性能，需要按照以上步骤检查和清除或者防御通过第一步发现占会话总数较多的ID，通过第二步检查该ID是否存在不法app或者其他流量，通过Dos保护或者会话限制该IP 数目（如果确定是攻击，可以通过安全策略屏蔽该IP地址访问）。
3.清除会话命令：Clear session all举例：可通过session id 、源或目的IP、源或目的端口或清除所有会话。
说明：将会话清除。
4.抓包和过滤在做debug/less或者抓包调试的时候，最好把PA的fastpath 功能关掉，这样可以更加完整的看到交互的数据报文，关闭命令为：Set deviceconfig setting session offload noSet session offload no命令：1、创建过滤规则：2、Debug dataplane packet-diag set filter match sourcedestination 开启过滤规则：Debug dataplane packet-diag set filter on3、配置抓包对象：Debug detaplane packet-diag set capture stage receive file （抓取来自接口接收的报文）Debug detaplane packet-diag set capture stage transmit file （抓取地址转换后的报文）Debug detaplane packet-diag set capture stage firewall file （抓取经过防火墙的报文）4、全局抓包开关：Debug detaplane packet-diag set capture on5、查看全局抓包配置：Debug detaplane packet-diag show setting6、关闭抓包Debug detaplane packet-diag set capture off7、清除所有抓包内容Debug detaplane packet-diag clear all8、删除文件Delete debug-filter file举例：说明：paloalto可以通过抓包的方式来分析故障情况。
