PEM - Privacy Enhanced Mail
Privacy Enhanced Mail (PEM) is a security standard that extends the email infrastructure to support encrypted and authenticated communications. It was initially developed in the 1980s as part of the efforts to enhance the security and privacy of email communication. PEM provides mechanisms for securing email messages through encryption and digital signatures, ensuring the confidentiality and integrity of the transmitted information.
The Security+ exam may cover basic concepts of email security, including encryption and digital signatures. While PEM may be mentioned, a broader understanding of email security standards like S/MIME and the principles of PKI is crucial for the exam.
