It\u2019s instant panic.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">Why? With the way systems are interconnected, even a single employee password can expose incredible amounts of sensitive data; user data as well as company data and additional credentials like API keys and DKIM keys.\u00a0<\/p>\n\n<h2 class=\"wp-block-heading\">How does key rotation enhance security?<\/h2>\n\n<p class=\"wp-block-paragraph\"><b>Key rotation is the process of periodically changing the credentials protecting your resource to reduce the risk of unauthorized access.\u00a0<\/b>\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">Just like runners, keys can become exhausted. Key exhaustion occurs when keys are used beyond their authorized lifespan. Your company may have time limits for keys to protect against exposure, but also to keep them from being encrypted with too much content.\u00a0<\/p>\n    <div data-content-type=\"longform\"  class=\"callout text-body-color px-5 py-6 px-md-6 px-lg-7 py-md-7 longform-spacings rounded-lg bg-light\" data-theme=\"light\">\r\n\r\n        <div class=\"content-body\"> Key rotation serves two purposes, to protect access by limiting exposure, and to keep the amount of encrypted data to a minimum in case keys become exposed.\u00a0<\/div>\r\n    <\/div>\r\n\n<p class=\"wp-block-paragraph\">When we talk technology, keys exist everywhere.

Once the signature is added, the message can be resent, or \u201creplayed\u201d over and over to a high volume of recipients. If the message content doesn\u2019t change, the signature will still be validated by the receiving mail server.\u00a0\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\"><b>DKIM key rotation <\/b>limits the exposure these bad actors gain to your reputation by cycling the key credentials so they are not able to validate their messages.\u00a0<\/p>\n\n<h2 class=\"wp-block-heading\">DKIM best practices for account protection<\/h2>\n\n<p class=\"wp-block-paragraph\">DKIM verifies the authenticity of emails and prevents spoofing. To ensure effective DKIM implementation, here are some best practices:\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\">Rotate DKIM keys regularly<\/h3>\n\n<p class=\"wp-block-paragraph\">But implementing DKIM isn\u2019t enough. Just like any other credentials, DKIM keys should be rotated periodically to maintain security.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">Set a schedule to update your DKIM keys at regular intervals, such as every few months or as recommended by your email service provider. At Mailgun, we recommend rotating DKIM keys every 6 months.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">To do so, \u2026.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\">Monitor DKIM authentication status<\/h3>\n\n<p class=\"wp-block-paragraph\">Stay vigilant by monitoring the DKIM authentication status of your outgoing emails.\u00a0\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">Regularly check reports and logs provided by your email service provider to detect any anomalies or potential vulnerabilities.\u00a0<\/p>\n    <div data-content-type=\"longform\"  class=\"callout text-body-color px-5 py-6 px-md-6 px-lg-7 py-md-7 longform-spacings rounded-lg bg-light\" data-theme=\"light\">\r\n\r\n        <div class=\"content-body\"> Learn more: Manage multiple senders and unlock sending flexibility at scale by generating <a href='https:\/\/www.mailgun.com\/es\/blog\/product\/mailgun-ip-pools-domain-keys\/'>API keys for specific domains.<\/a> \u00a0<\/div>\r\n    <\/div>\r\n\n<h2 class=\"wp-block-heading\">Consequences of compromised API Keys<\/h2>\n\n<p class=\"wp-block-paragraph\"><b>APIs connect two software components together and allow them to communicate. <\/b>The way that APIs can communicate with one another are defined by the writers of the API through definitions and protocols.

Don\u2019t hardcode keys within your source code or public repos, and don\u2019t leave your laptop unattended in a public space.\u00a0<\/p>\n    <div data-content-type=\"longform\"  class=\"callout text-body-color px-5 py-6 px-md-6 px-lg-7 py-md-7 longform-spacings rounded-lg bg-light\" data-theme=\"light\">\r\n\r\n        <div class=\"content-body\"> <b>Regular rotation ensures that even if a key is compromised, its usefulness to attackers is limited.<\/b> We recommend rotating your DKIM keys every 6-12 months as a best practice.\u00a0<\/div>\r\n    <\/div>\r\n\n<h3 class=\"wp-block-heading\">Rotate API keys regularly<\/h3>\n\n<p class=\"wp-block-paragraph\">By combining regular DKIM rotation with other security measures like IP allowlisting and role-based access control (RBAC) for API keys, you can significantly enhance the overall security of your email infrastructure.\u00a0<\/p>\n\n<ul class=\"wp-block-list\">\n<li><b>IP Allowlist: <\/b>An IP allowlist restricts which IPs (or IP ranges) are allowed to make API calls for your account.

Instead of brushing twice daily, use unique passwords and encrypted storage. Instead of flossing, implement tools like 2FA and educate your team on password protection and phishing scams.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\">Use strong, unique passwords<\/h3>\n\n<p class=\"wp-block-paragraph\">Create complex passwords that include a combination of uppercase and lowercase letters, numbers, and special characters. Not feeling very creative? That\u2019s OK \u2013 use a password generator to help you manage password creation.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">As a best practice, avoid reusing passwords across different platforms and use encryption and secure storage to save all your credentials.\u00a0<\/p>\n\n<h2 class=\"wp-block-heading\">Implement two-factor authentication (2FA)<\/h2>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.mailgun.com\/es\/blog\/product\/protege-tu-cuenta-autenticacion-dos-fases-seguridad\/\" target=\"_tabs\" rel=\"noopener noreferrer\"><u>Enable 2FA<\/u><\/a> whenever possible to add an extra layer of security to your accounts.
