They serve for the same purpose as signatures on paper docs. In Exchange Server 2019, digital signatures are utilized by deploying Secure\/Multipurpose Internet Mail Extensions (S\/MIME), and provide the following security features.<\/p><ul><li><strong>Authentication.<\/strong> SMTP protocol, used for email communication, lacks many security features, including the <a href=\"https:\/\/infrasos.com\/how-to-enable-smtp-authentication-in-office-365\/\">authentication<\/a>. It makes it impossible to determine the true sender of a message, allowing malicious actors to impersonate the senders. Digital signatures address this issue by allowing recipients to verify that a message indeed comes from the claimed sender. Provides a means to establish trust (using the digital certificate) in the authenticity of the communication.<\/li><li><strong>Non repudiation. <\/strong>Non repudiation ensures that an individual cannot disclaim the performed action (in the email messaging context, the action is the sending of the message). It significantly complicates any attempt to refuse the authenticity of a message. Makes it highly challenging to deny responsibility. As a result, digitally signed messages are considered more trustworthy than non-signed ones.<\/li><li><strong>Data Integrity.<\/strong> Digital signatures also enhance security by ensuring data integrity. For example, you send a signed message to your colleague. It gets altered during the SMTP flow by a hacker. In this case the message loses the signature. Presence of a digital signature on a message proves that the email message is in the same state as it was intended by the sender.<\/li><\/ul><p>Digital signature proves the message comes from the specified sender and that it wasn\u2019t altered during the transport. S\/MIME uses the asymmetric cryptography (public-private key pair) to sign the messages.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2c2f893 elementor-widget elementor-widget-image\" data-id=\"2c2f893\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.12.2 - 23-04-2023 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/infrasos.com\/wp-content\/uploads\/2024\/01\/SEC01-1.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"Secure Email Communication with Microsoft Exchange Server\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NTYzOTcsInVybCI6Imh0dHBzOlwvXC9pbmZyYXNvcy5jb21cL3dwLWNvbnRlbnRcL3VwbG9hZHNcLzIwMjRcLzAxXC9TRUMwMS0xLnBuZyJ9\">\n\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/infrasos.com\/wp-content\/uploads\/elementor\/thumbs\/SEC01-1-qii0do9jhd70rdlkkh41l01r114o53kfqxpwo71tgs.png\" title=\"Secure Email Communication with Microsoft Exchange Server\" alt=\"Secure Email Communication with Microsoft Exchange Server\" loading=\"lazy\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c8be853 e-con-boxed e-con\" data-id=\"c8be853\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-649385a elementor-widget elementor-widget-text-editor\" data-id=\"649385a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>As shown on the above image, digital signature with S\/MIME works the following way:<\/p><ol><li>The private key (only available for the sender) is used to sign the message.<\/li><li>The signed message is sent to the recipient.<\/li><li>Recipient uses the public key (available for everyone) to verify the signature.<\/li><\/ol><p>To use S\/MIME in your Exchange Server infrastructure, you need have the necessary public key infrastructure \u2013 to issue the necessary key pairs.
