E-mail security

What does E-mail security?

Since email remains the preferred means of communication even in the age of video calls and messaging apps, great importance should be placed on ensuring a correspondingly high level of security. Where possible, a modern Encryption after the State of the art must be taken into account. A distinction must be made here between Encryption the transmission path—that is, from the email client to the incoming or outgoing server, the path between these two, and the Encryption the email content or attachments themselves. The first point is no longer an issue these days, since all major email providers now offer encrypted transmission. The Encryption Encrypting the content, however, is somewhat more problematic. This is because the sender and recipient must agree on an encryption method. This could be, for example, an S/MIME certificate or a PGP/GPG key. Further information can be found on the BSI website, for instance.
