Espec\u00edficamente, los servicios de correo que utilizan este mecanismo podr\u00e1n crear conexiones SMTP seguras (utilizando TLS) con otros servidores de correo electr\u00f3nico. MTA-STS tambi\u00e9n puede utilizarse para rechazar la entrega de mensajes a servidores de correo que no ofrezcan TLS con un certificado de servidor confiable.  <\/p>\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Dado que este mecanismo invoca el uso de TLS, se utiliza el Informe de TLS (TLS-RPT) para determinar si se estableci\u00f3 o no una conexi\u00f3n segura. Estos informes provendr\u00e1n de servidores externos que realizan conexiones a su dominio. <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h2 class=\"wp-block-heading\">Lo que protege<\/h2>\n\n<p class=\"wp-block-paragraph\">MTA-STS protege contra las siguientes amenazas:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Ataques de intermediario \u2013 esto ocurre cuando un atacante intercepta mensajes entre dos servidores de correo electr\u00f3nico. El objetivo es robar o alterar los datos, y luego enviarlos al destinatario. <\/li>\n\n\n\n<li>Ataques de degradaci\u00f3n \u2013 esto ocurre cuando el atacante fuerza la comunicaci\u00f3n a cambiar a un modo inseguro (dejando de utilizar TLS).<\/li>\n\n\n\n<li>Ataques de suplantaci\u00f3n de DNS \u2013 este tipo de ataque modifica el registro DNS del destino previsto, enga\u00f1ando as\u00ed al usuario para que crea que est\u00e1 visitando un sitio o dominio leg\u00edtimo.<\/li>\n<\/ul>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<div class=\"gca-short-launch-box\">\n    <div class=\"container\">\n        <div class=\"content-wrapper\">\n            <div class=\"image-container\">\n                            <\/div>\n            <div class=\"content\">\n                                    <p>Nuestro Campo de Entrenamiento de DMARC ofreci\u00f3 cinco semanas de formaci\u00f3n t\u00e9cnica en l\u00ednea gratuita centrada en DMARC, incluyendo los fundamentos de SPF y DKIM, y MTA-STS.<\/p>\n                                \n                <div class=\"button-container\">\n                                            <a href=\"https:\/\/globalcyberalliance.org\/gca-tool\/dmarc\/\" class=\"button\">\n                                                        <span class=\"button-text\">\u00a1Vaya al Campo de Entrenamiento de DMARC!<\/span>\n                        <\/a>\n                                    <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n<\/div> \n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<div class=\"gca-tools-feed\">\n    <div class=\"content-container\">\n                    <h3 class=\"title\">OTRAS HERRAMIENTAS Y PROYECTOS DE GCA<\/h3>\n        \n                    <div class=\"tools-grid\">\n                                    <article class=\"tool-card\">\n                                                    <div class=\"tool-image\">\n                                <img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"645\" src=\"https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-scaled.png\" class=\"attachment-post-thumbnail size-post-thumbnail wp-post-image\" alt=\"\" srcset=\"https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-scaled.png 2560w, https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-300x76.png 300w, https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-1024x258.png 1024w, https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-768x194.png 768w, https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-1536x387.png 1536w, https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-ACT-Logo-Full-Color-2048x516.png 2048w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/>                            <\/div>\n                        \n                        <div class=\"tool-card-content\">\n\n                            <div class=\"tool-excerpt\">\n                                Learn more about this tool                            <\/div>\n\n                            <a href=\"https:\/\/globalcyberalliance.org\/es\/work\/herramientas-de-ciberseguridad-accionables\/\" class=\"learn-more\">\n                                LEARN MORE\n                            <\/a>\n                        <\/div>\n                    <\/article>\n                                    <article class=\"tool-card\">\n                                                    <div class=\"tool-image\">\n                                <img loading=\"lazy\" decoding=\"async\" width=\"480\" height=\"136\" src=\"https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-AIDE-Logo-FullColor.png\" class=\"attachment-post-thumbnail size-post-thumbnail wp-post-image\" alt=\"\" srcset=\"https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-AIDE-Logo-FullColor.png 480w, https:\/\/globalcyberalliance.org\/wp-content\/uploads\/2025\/04\/GCA-AIDE-Logo-FullColor-300x85.png 300w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/>                            <\/div>\n                        \n                        <div class=\"tool-card-content\">\n\n                            <div class=\"tool-excerpt\">\n                                Haga Algo.
