Coursera 课程摘要：DMARC 基础 本课程深入探讨了电子邮件安全的关键领域，特别是如何利用 DMARC（基于域的消息认证、报告和一致性）协议来抵御日益增长的电子邮件欺诈和钓鱼攻击。 **课程核心内容：** * **电子邮件安全的挑战：** 课程首先强调了电子邮件作为企业沟通生命线的同时，也是恶意软件、勒索软件等攻击的主要入口。邮件欺骗（email spoofing）是其中一种常见的威胁。 * **DMARC 的作用：** DMARC 的目标是识别和阻止冒充您公司域名的邮件，从而保护您的组织和客户免受欺骗性通信的侵害。 * **SPF 和 DKIM 的协同作用：** DMARC 的实现离不开 SPF（发件人策略框架）和 DKIM（域名密钥识别邮件）这两个核心组件。 * **SPF** 定义了哪些服务器被授权代表您的域名发送邮件，帮助接收方验证发件人身份。 * **DKIM** 允许您的邮件服务器在发送的每封邮件上进行数字签名，接收方可以通过验证签名来确认邮件真实性和未被篡改。 * **理解协议原理：** 本课程将帮助您全面理解 SPF、DKIM 和 DMARC 这三个协议的基本概念，以及它们如何协同工作，共同增强您域名的电子邮件安全性，有效降低邮件欺诈的风险。
Email is a vital communication medium that is used by every business around the globe. Email is also one of the primary attack vectors that can introduce malware, ransomware and other malicious code into your environment. These attacks can come in many forms including email spoofing.DMARC is designed to help mitigate this risk and ensure that spoofing your company domain is identified and blocked, including communication targeted at your organization or customers.DMARC standards for Domain Based Message Authentication, Reporting and Conformance. DMARC utilizes both SPF and DKIM in order to make a determination on how to handle email that is coming inbound to your organization as well as messages that are sent outbound from your domain.SPF stands for sender policy framework, and this specifies the servers that are allowed to send email on your behalf.DKIM is an acronym for Domain Keys Identified Mail. This allows your mail server to digitally sign each message that is sent out from your domain. The recipient can then verify that the email was sent from your server and has not been altered in transit.This course will help you understand the fundamental concepts of these three protocols and how they work in conjunction with each other to help mitigate the risk of email spoofing from your domain.
