Fortinet 完整安全解决方案概述说明书

Complete Small and Midsize Business Protection Consolidated Management. Proven Security. Maximum Value.Executive SummaryWith 43% of attacks in 2019 targeting small and midsize businesses (SMBs),1 security is no longer a topic business leaders can ignore yet remains one of the most intimidating subjects for many leaders to tackle.New technologies and working models expose new risks, meaning effective security must be complete security. The good news is security has gotten much better. Leading security vendors like Fortinet are continually validated by third-party testing groups to effectively prevent threats across a broad range of tactics. Built off the same underlying code and taking advantage of custom-built hardware, the Fortinet Security Fabric effectively stops attacks and automatically communicates to reduce false alerts and maintenance. By taking advantage of a single vendor approach, workloads drop, operational efficiency increases, and securing your business suddenly becomes much easier.Designed to maximize simplicity, Fortinet Small and Midsize Business Security Solutions deliver a path to complete protection. Clear ROI is delivered without sacrificing security with tight integration, automation, and visibility across your entire cybersecurity footprint to improve effectiveness, reduce cycles, and scaleas your company grows. Cloud-based, centralized management simplifies ongoing operations with business-driven rules and policies so you can quickly consume new technology while keeping your business safe from attack.Fortinet SMB Security SolutionsSecure Office NetworkingAt the heart of any cybersecurity solution is its ability to protect the business from incoming network attacks. Next-generation firewalls (NGFWs) understand howthe combination of the user, the device they’re using, and the application they’re interacting with should behave, analyze the traffic and ultimately understand how it should be transmitted, replacing the need for traditional routers.The NGFW is just part of the solution. For traffic to ultimately reach the user, or for the user or device to reach the internet, traffic must travel through two key devices that help scale network access around the office—switches for wired devices and wireless access points (APs) for wireless connectivity.The combination of these three devices—NGFW, switch, and wireless AP—form the core of network connectivity. Businesses need both high performance and strong security from their network, and with Fortinet, you can have both and enable safe access to the cloud with built-in Secure SD-WAN at no additional cost.nn FortiGate: The most cost-effective NGFW for performance and protection3 with built-in Secure SD-WAN to better control network performance to cloud-based applications and secure traffic.Fortinet SMB Security Solutions Provide Affordable, Complete Securitynn Secure Office Networking: Protect the traditional office network while enabling a hybrid work force.nn Endpoint and RemoteUser Protection:Enable your users to work from anywhere with leading endpoint security and secure access.nn Secure Cloud Applications and Email:Build out the secure cloud-connected office and take full advantage of the cloud.nn Cloud-based Management and Analytics:Streamline and simplify security, management, and ongoing operations.SOLUTION BRIEFTwo-thirds of organizationsare actively consolidatingthe number of cybersecurityvendors with which they dobusiness for better operationalefficiency and cost savings.2nn FortiAP: High-performance, Wi-Fi 6 ready APs ensure strong connectivity even in dense, highly populated environments.n FortiSwitch: Stackable, Power over Ethernet (PoE) functionality delivers performance and scale to meet any need.nUnified security across firewalls, switches, and wireless access pointsBy consolidating Layer 7 routing and multiple security services into a single, industry-leading NGFW, many business are able to reduce the cost of multiple licenses and the oversight needed to maintain a strong security position as multiple needs are solved by one. With Fortinet, this exercise in simplicity extends even further thanks to proprietary technology that allows administrators to extend this security to FortiSwitches and FortiAPs, creating a truly secure connectivity environment for the office. FortiGate NGFW consolidates security functions*n Anti-malware/antivirus: Prevents basic malware, threats, and bot activitynn Intrusion prevention (IPS): Uncovers advanced threats hidden deep within packets missed by basic antivirusnn Virtual private network (VPN): Creates an encrypted, private communication through the public web between user and office network nn Web and content filtering: Enable SafeSearch and block traffic to explicit and malicious websitesn*For a complete list of security services available to the FortiGate, please discuss with your Fortinet representative or authorized partner.Simple, high-performance connectivity with built-in Secure SD-WANAs your business grows and more users and devices need to connect in and around the office and to the cloud, network bottlenecks can quickly hinder productivity. Fortinet FortiGate NGFWs, along with FortiAP wireless access points and FortiSwitches, provide industry-leading network connectivity while maintaining enterprise-grade security. Additionally, built-in Secure SD-WAN helps improve cloud-based application performance over multiple paths while retaining strong security. Fortinet Secure SD-WAN enables fast access to cloud-based applications and high-quality experiences in multi-cloud environments by self-healing for data loss and network speed before it affects the application. As an integrated component of the FortiGate, organizations are protected against the latest risk exposures and evolving sophisticated attacks included for no additional cost and without the headache of configuring and managing another point product.Endpoint Protection and Remote User ProtectionAs workers increasingly move outside the traditional office environment on a permanent or semi-permanent basis, the need for strong endpoint protection, detection, and remediation increases in importance. With a combination of FortiClient and FortiEDR, businesses can obtain rich visibility and control over endpoint hygiene, network access, and discover and prevent malicious attacks like ransomware from spreading across the network.Endpoint visibility and controlFortiClient was designed to natively integrate with the larger Fortinet Security Fabric. Tight integration with the FortiGate NGFW allows administrators to easily drill into user devices and assess risk level, network access, and ensure content filtering policies remain consistent even when users are offline.Secure access and VPNFortiClient also includes a free client VPN service to ensure users are protected anywhere they log in. With built-in auto-connect and split-tunneling capabilities, there is no need to purchase a standalone VPN solution and further complicate the environment. Real-time breach protection and ransomwareWith FortiEDR, businesses can raise their level of preparedness and block exploits, stop breaches, data exfiltration, and ransomware attacks automatically, without disrupting business operations. FortiEDR brings multilayer detection and prevention technology such as machine learning (ML), patented code-tracing technology, and automated response and remediation procedures.Secure Cloud Applications and EmailThe cloud offers businesses a wealth of efficiency and simplicity while trading out control. Protecting the information stored within these services often falls unknowingly on the business rather than the application vendor. With Fortinet, administrators can build out a secure cloud-connected office by securely accessing cloud-based applications with SD-WAN, virtual firewalls to protect data across AWS, Azure, GCP, and Oracle Cloud, and ensuring email is protected when using popular platforms such as Microsoft 365 and Google Mail.Copyright © 2021 Fortinet, Inc.

Built for the cloud, FortiGate VMs deliver protection across public, private, and multi-cloud environments.n n Safely leverage cloud benefits of scalability, metering, and time to market with cloud-native securityn n Seamlessly scale without increasing operational burdensn n Flexible consumption models include licensing and on-demand usage modelsEnhanced email securityEmail continues to be the top method of attack used by attackers to dupe unsuspecting users into running malicious files and clicking on malicious links through phishing and other business email compromise (BEC) schemes. FortiMail Cloud offers unparalleled protection to remove these risks from your workforce and provide additional protection to popular email platforms such Microsoft 365 and Google Mail.Cloud-based Management and AnalyticsSecurity works on the premise of understanding what is good, what is not, and responding accordingly. When different vendor products perceive a threat differently, conflicts arise, leaving the burden of analysis on the administrator. With Fortinet,automated information sharing across the solution and the ability to manage it from a single pane of glass help streamline and simplify security, management, and ongoing operations.Cloud-based managementCentralized, cloud-based management of the complete SD-Branch (NGFW, AP, Switch, SD-WAN, Security), FortiGate Cloud, is included with the purchase of the FortiGate NGFW. From here, administrators can simplify deployments, management, and troubleshooting with actionable insights and visual reports of their basic network.As locations and implementations grow and/or additional Fortinet security products are installed, businesses can easily upgrade to FortiManager and FortiAnalyzer to centralize all administrative tasks.A Solid Security Foundation on Which To Build Y our BusinessTechnology both enables productivity and increases the risk of a breach as the attack surface grows. Looking across the security landscape, there are many options and closer inspection regularly finds critical holes in a vendor’s offerings such as:n n Limited solutions forcing you to purchase from multiple vendors to protect everything and stitch them together yourself n n Confusing implementation and management that result in ineffective protectionn n Expensive solutions that claim to protect everything and leave no budget for anything elseFortinet SMB Security Solutions are engineered to scale as your business grows and give you the confidence of investing in a market-leading security platform designed to reduce workloads while maintaining security. Only Fortinet offers this breadth of small business offerings validated by security experts.Curious where to start?

常见安全漏洞
• SQL Injection(SQL注入) • Cross-Site Scripting (跨站脚本攻击) • Log Forging(日志攻击) • Unrelease Resource(资源未释放)
Cross-Site Scripting (跨站脚本攻击)
攻击者向动态Web页面里插入恶意 HTML代码,当用户浏览页面时,嵌入的 恶意代码被执行从而达到攻击的目的。
在输入的字符串之中注入恶意的SQL指令,这些注 入的指令会被数据库误认为是正常的SQL指令进行执行, 使系统遭到破坏。
注入原理(1)
SELECT * FROM items WHERE owner = #userName# AND itemname = '$itemName$‘
• 使用SQL关键字(AND/OR/DELETE/UPDATE)
正常日志: INFO:Failed to parse val=twenty-one 恶意日志:
若value输入:
twenty-one%0a%0aINFO:+User+logged+out%3dbadguy
输出:
INFO:Failed to parse val=twenty-one INFO:User logged out=badguy
itemName = ‘name’ or ‘1’=‘1’ itemName = ‘name’ ;Delete from items
注入原理(2)
• 使用特殊符号(% , --)
itemName = ‘%name%’; itemName = ‘name;delete from items ;--’

• URL重定向校验
(1)空格符、制表符和换行符标记了 URL 的结束。 (2) "&" 引入一个字符实体 (3)非 ASCII 字符(即 ISO-8859-1 编码表中所有高
于 128 的字符)不允许出现在 URL 中,因此在此上 下文中也被视为特殊字符。 (4)在服务器端对在 HTTP 转义序列中编码的参数进行 解码时,必须过滤掉输入中的 "%" 符号。
XSS分类(1)
• Reflected XSS(反射式XSS)
程序从 HTTP 请求中直接读取数据,并在 HTTP 响应 中返回数据。当攻击者诱使用户为易受攻击的 Web 应用程 序提供危险内容,而这些危险内容随后会反馈给用户并在 Web 浏览器中执行,就会发生反射式 XSS 。
• 示例代码
<% String eid = request.getParameter("eid"); %> Employee ID:<%= eid %>
解决方案(1)
• 入参和出参校验
(1)“< >” 可以引入一个标签或者结束一个标签。 (2) "&" 可以引入一个字符实体。 (3)对于外加双引号的属性值,双引号(””)是特殊字符,因
为它们标记了该属性值的结束。 (4) 对于外加单引号的属性值,单引号(‘’)是特殊字符,因
为它们标记了该属性值的结束。
• 程序可能无法成功释放某一项已申请的 系统资源。
• 如果攻击者能够故意触发资源泄漏,就 有可能通过耗尽资源池的方式发起 DOS(Denial Of Service)攻击。
(1)Oracle select * from t_user where name like '%'||#name #||'%' ; (2)Mysql select * from t_user where name
like concat('%',#name #,'%') ; (3)Mssql
select * from t_user where name like '%'+#name #+'%
示例代码பைடு நூலகம்
String val = request.getParameter("val"); try {
int value = Integer.parseInt(val); }catch (NumberFormatException) {
("Failed to parse val = " + val); }
常见安全漏洞
• SQL Injection(SQL注入) • Cross-Site Scripting (跨站脚本攻击) • Log Forging(日志攻击) • Unrelease Resource(资源泄漏)
Log Forging(日志攻击)
将未经验证的用户输入写入日志文件, 致使攻击者伪造日志条目或将恶意信息 内容注入日志。
对于Ibaits参数引用可以使用#和$两种写法。 (1)#写法会采用预编译方式,将转义交给了数据库,会
自动在参数的外面加上引号,不会出现注入问题。
(2)$写法相当于拼接字符串,会出现注入问题。
解决方案(1)
• 对于所有请求进行入参的过滤
解决方案(2)
• 避免使用 $ 字符拼接变量的情况
select * from t_user where name like ‘%$name$%’;
XSS分类(2)
• Persisted XSS(持久式CSS)
程序将危险数据储存在一个数据库或其他可信赖 的数据存储器中。这些危险数据随后会被回写到应用 程序中,并包含在动态内容中。
• 示例代码:
JAVA代码:String name = dao.queryName(id);
JSP代码:Employee Name:<%= name %>
