Cyber Security is a must of all businesses. Cyber Insurance is a key piece of Cyber Security. Cyber Insurers are now starting to require the implementation of email authentication. The following are controls that with help of a cyber security vendor can be implemented within 24 hours.
Email authentication standards:
SPF – Sender Policy Framework hardens your Domain Name Servers and restricts who can send emails from your domain. SPF is used to prevent domain spoofing. It uses your mail server to determine if a message came from the domain that it uses.
DKIM – DomainKeys Identified Mail ensures that the contents of an email have not been tampered with or compromised.
DMARC – Domain-based Message Authentication, Reporting and Conformance ties the first two together with a consistent set of rules. It links the sender’s domain with what is listed in the “from” header and ensures the integrity of email contents.
The easiest of these controls to implement is SPF. If the firm uses Office 365, they have an article at the following link regarding the implementation of SPF.
