Email security is a term used for any procedure that protects email content and accounts from unauthorized access. Email service providers have email security measures to protect customer accounts and information from hackers.
HOW SAFE IS EMAIL?
Email is designed to be as open and accessible as possible. It allows people in organizations to communicate with each other and with people in other organizations. The problem is that the email is not secure. An email is a popular tool used among hackers to spread malware, spam, and phishing attacks. Whether through spam campaigns, malware and phishing attacks, advanced targeted attacks, or business email security breaches (BEC), attackers try to exploit the lack of email security to take action. Email is also an important entry point for attackers who want to access a corporate network and capture important company data.
WAYS TO PROVIDE SECURE E-MAIL COMMUNICATION.
1. DMARC
DMARC (Domain-based Message Authentication Reporting and Conformance) is an e-mail verification system designed to prevent your company's e-mail domain from being used for e-mail fraud, phishing fraud, and other cybercrime. DMARC uses existing e-mail authentication techniques SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail). DMARC adds an important function as reporting. When a domain owner publishes a DMARC record, their DNS records have information about who sent the email on behalf of their domain name. This information can be used to get detailed information about the e-mail channel. With this information, a registrant can have control over the e-mail sent on his behalf.
2.SPF
SPF (Sender Policy Framework) is an e-mail authentication technique used to prevent spammers from sending messages on behalf of your domain. With SPF, an organization can publish authoritative mail servers. Together with DMARC, it provides information to the recipient (or recipient systems) about this e-mail reliability. SPF, like DMARC, is an e-mail authentication technique that uses DNS (Domain Name Service). This allows you, as an email sender, to determine which email servers are allowed to send an email on behalf of your domain.
3.DKIM (Domain Keys Identified Mail)
DKIM (Domain Keys Identified Mail) is an email authentication technique that allows the recipient to check that an email is actually sent and authorized by the owner of that domain. This is done by giving the e-mail a digital signature. This DKIM signature is a header attached to the message and protected by encryption.

When the recipient (or the receiving system) determines that an email was signed with a valid DKIM signature, it is certain that there are parts of the email that have not changed the message body and attachments. Usually, DKIM signatures are not visible to end-users, validation is done at a server level.
