To answer this most valid question, are you willing to put all your data, communication, and information stored online at stake? Ofcourse not! No one is. That is where the term email security comes into the picture.
Emails are usually associated with formal communication between organizations, internal and external communications in companies, or used for official business mails.
Subsequently, they may contain some confidential information or sensitive data that should be encrypted only to end users.
In absence of appropriate email security, these information and data may get leaked, or tampered with while the mail is in transit without the recipient knowing about it. This may affect the credibility of any highly important information shared via email.
So in order to ensure the authenticity of data and information shared over emails, it is important to secure your domain and limit its uses as a sending organization and restrict your inbox placement as a receiver.
Master Email Security
Having been informed about the importance of email security, you might have understood how important it is for everyone to know this.
Phishing and Email spam are the most common ways often opted by hackers to enter a network. Being a sender you need to ensure that the recipient of your mail should receive it in the most authentic and untampered form.
There are various configurations forms of email authentication protocols that one must know in order to achieve a secured end-to-end encrypted network and malicious free emailing options. SPF, DKIM, and DMARC are some of the most effective authentication protocols.
Check out each of them in detail.
Sender Policy Framework Email security
SPF or Sender Policy Framework is an email security protocol that authenticates emails and limits identifiable IP addresses for senders to maintain the credibility of the domain.
The DNS entry contains additional information about authentic information about IP address that can send mail on behalf of organisation’s domain. An SPF Record is also a record of Domain Name Service that enables the recipient server to know if the email is received from an authentic sender or not.
This is most effective against typical phishing attacks in which email header of the official address or known organization is spoofed to make it look like a mail from some official business entity or known person and send attacking mails.
The email serve matches the IP address to that present in DNS records. If the sender is genuine the SPF Record is found for the same and if it’s not, the email might get failed.
Domain Keys Identified Mail for Email security
DKIM or Domain Keys Identified Mail is a security protocol that allows an organisation to ensure the security of a mail while transmitting by signing it specifically. This sign consists of the various field like subject, body, address, DNS, etc which are required to match for successful authentication.
Once the email reaches the receiver, he can check for the authentic cryptographic signature on the email. This unique signature enables the receiver to check for tampering done to the email body or email header while it was in transit.
Simply put, DKIM enables the sender to add an extra shield by adding a unique cryptographic signature to the mail. This enables the identification of tampering done with the mail while it is in transit.
This is used to identify spoofing to avoid phishing attacks done by tampering with emails while in transit. This gives additional security to both the sender and the receiver.
Domain-Based Message Authentication Reporting and Conformance
DMARC or Domain-Based Message Authentication Reporting and Conformance is an advancement to ensure the security of email services. This is the most efficient email security service as both Senders Policy Framework and Domain Keys Identified Mail is required to match the DNS records to verify the authenticity of the sender of any email.
This improves the number of email delivery and also makes a better inbox placement with stronger protection provided to the receiver of your email.
This not only prevents spoofing of email and phishing attacks but also blocks malicious or tampered signatures sent from the domain to get extra resistance against spoofing.
