- Key aspects of email security include:

> 1. Encryption: Encrypting email messages ensures that only authorized recipients can decipher and read the content of the message. There are two main types of email encryption:

- Transport Layer Security (TLS): TLS encryption ensures that the communication between email servers is secure during transmission, protecting the message from interception.
- End-to-End Encryption: This type of encryption ensures that the content of the email is encrypted on the sender's side and can only be decrypted by the intended recipient. Services like PGP (Pretty Good Privacy) and S/MIME (Secure/Multipurpose Internet Mail Extensions) offer end-to-end encryption for email.

> 2. Authentication: Email authentication mechanisms help verify the authenticity of the sender and prevent email spoofing, where malicious actors pretend to be legitimate senders. Common authentication techniques include:

- Sender Policy Framework (SPF): SPF helps verify that the sending server is authorized to send emails on behalf of the domain in the sender's email address.
- DomainKeys Identified Mail (DKIM): DKIM adds a digital signature to email headers to verify that the email content has not been tampered with and that it comes from a legitimate source.
- Domain-based Message Authentication, Reporting, and Conformance (DMARC): DMARC combines SPF and DKIM to provide more comprehensive email authentication and reporting capabilities.
