Security in electronic communication
Improve email authentication and protect their online reputation
Internet security is a serious issue, especially when it comes to e-mail communication. A large proportion of email spam and phishing attacks are made possible by forged sender addresses. To combat this problem, technologies such as DKIM, DMARC and SPF have been developed.
DKIM
stands for "DomainKeys Identified Mail" and is a method for digitally signing emails. It enables the recipient to check whether an email actually originates from the specified sender domain and whether the content of the message has remained unchanged. With DKIM, companies and organizations can ensure the integrity of their emails and reduce the risk of phishing attacks.
SPF
(Sender Policy Framework) is another technology that helps to combat email fraud. It enables the recipient to check whether an email has been sent from an authorized IP address. SPF can help to verify the sender and reduce the risk of spam and phishing attacks.
DMARC
(Domain-based Message Authentication, Reporting & Conformance) is a technology that builds on DKIM and SPF and facilitates the implementation and monitoring of these technologies. It enables domain owners to set email authentication policies and receive reports on emails sent from their domains. DMARC provides an additional layer of protection against email fraud and can help protect a domain's reputation.
