color: #000000;\">Hackers don\u2019t need rocket science to launch <strong><span style=\"color: #183994;\"><a style=\"color: #183994;\" href=\"https:\/\/threatcop.com\/blog\/email-threats\/\">email-based attacks<\/a><\/span><\/strong>. The most common weapon they use for these attacks is <span style=\"color: #183994;\"><a style=\"color: #183994;\" href=\"https:\/\/threatcop.com\/blog\/email-spoofing\/\"><strong>email spoofing<\/strong><\/a><\/span>. Hackers spoof email accounts to send fraud and malicious emails on behalf of victims. Or even ask your contacts to wire money to a fake account by using the spoofed email address.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Therefore, to stop such email-based crimes, it is important to secure outbound emails so that recipients of emails are not duped by spoofed email addresses. There are three main email authentication protocols that every organization must implement for the email security of their domain: <\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span style=\"color: #000000;\"><strong>DMARC: <\/strong><\/span><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"color: #183994;\"><strong><a style=\"color: #183994;\" href=\"https:\/\/threatcop.com\/blog\/what-is-dmarc\/\">DMARC<\/a><\/strong><\/span><span style=\"font-weight: 400;\"> or Domain-based Message Authentication, Reporting, and Conformance is an email authentication protocol that is designed to secure email domains from unauthorized usage. <\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">The purpose of this protocol is to secure a domain from being misused in BEC attacks, phishing emails, email scams, etc. <\/span><span style=\"font-weight: 400;\">Once the DMARC DNS entry is published, the receiving email server (any) can authenticate inbound emails based on published instructions within the DNS entry by the domain owner. <\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">If the email makes it through, bypassing the authentication, it can be trusted to be delivered. In case the email fails the authentication, then depending upon the instructions and policies set within the DMARC record, it will be either delivered, quarantined, or rejected. <\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span style=\"color: #000000;\"><strong>SPF: <\/strong><\/span><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\"><strong><a style=\"color: #000000;\" href=\"https:\/\/threatcop.com\/blog\/spf-authentication\/\"><span style=\"color: #0000ff;\"><span style=\"color: #183994;\">SPF<\/span><\/span><\/a><\/strong> <span style=\"color: #000000;\">or Sender Policy Framework is an email authentication standard that is designed to identify forged email sender addresses during email delivery. In simple terms, it is a protocol with which mail servers decide whether to accept or reject the incoming email. <\/span><\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">This decision is made by using the SPF information TXT records as per the authorized IP addresses enlisted within the particular domain. Therefore, depending upon the list, the email sender\u2019s address is verified for whether it is forged or not. <\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">However, SPF alone is not enough since SPF in combination with DMARC can be effectively used to detect email spoofing. <\/span><\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span style=\"color: #000000;\"><strong>DKIM:<\/strong> <\/span><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\"><span style=\"color: #0000ff;\"><strong><a style=\"color: #0000ff;\" href=\"https:\/\/threatcop.com\/blog\/dkim\/\"><span style=\"color: #183994;\">DKIM<\/span><\/a><\/strong><\/span> <span style=\"color: #000000;\">or Domain Key Identified Mail is a type of email authentication technique that helps organizations claim responsibility for the email message in a way that it can be validated by the email recipient. <\/span><\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"> <span style=\"font-weight: 400;\">It allows the recipient to check whether the email was indeed sent and authorized by the domain owner by using \u201cpublic-key cryptography\u201d for verification. This verification key is called the DKIM signature which helps in detecting forged emails and prevents the delivery of spam or phishing emails. <\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\">This DKIM signature is secured with encryption and is added to the message as a header. It is usually not visible to the end-user and the validation is done at the server level. <\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\">Implementation of a DKIM standard <span style=\"color: #183994;\"><a style=\"color: #183994;\" href=\"https:\/\/threatcop.com\/blog\/increase-domain-reputation-and-email-deliverability\/\"><strong>improves email deliverability<\/strong><\/a><\/span> and when it is implemented together with DMARC and SPF, your domain is fully protected against malicious emails that are sent on your behalf.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><b>Did you find this blog helpful?
