Electronic Mail Security,Cryptography and Network Security [21CS733]

Electronic Mail Security
Electronic mail (email) security refers to the measures taken to protect email communications from unauthorized access, alteration, loss, or misuse. It encompasses a wide range of techniques to ensure confidentiality, integrity, and authenticity in email communication. Key aspects include:

Authentication: Verifying the sender's identity through protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).
Encryption: Securing email content during transit and at rest using encryption methods like S/MIME (Secure/Multipurpose Internet Mail Extensions) or PGP (Pretty Good Privacy).
Spam and Phishing Protection: Employing filters and tools to detect and block malicious or unwanted emails.
Secure Communication: Ensuring the transmission uses secure protocols like HTTPS, SSL/TLS, and STARTTLS to prevent interception by attackers.
Access Control: Using strong passwords, multi-factor authentication (MFA), and role-based access to protect email accounts and systems.
