Harness the Power of DNSSEC and DANE with Office 365 Exchange Online

Exploring Support of DANE and DNSSEC in Office 365 Exchange Online
Introduction
The Domain Name System Security Extensions (DNSSEC) and the DNS-based Authentication of Named Entities (DANE) protocol are both security protocols designed to protect Internet users by verifying the authenticity of the DNS records they request. DNSSEC ensures that the DNS records returned to a user are authentic and have not been tampered with, while DANE provides an additional layer of security by using digital signatures to verify the origin of the DNS record. In this article, we will discuss the support of DANE and DNSSEC in Microsoft’s Office 365 Exchange Online service.

What is DNSSEC?
DNSSEC is a protocol that provides a layer of security for DNS by digitally signing DNS records. This digital signature ensures that the DNS records returned to the user are authentic and have not been tampered with by a third party. DNSSEC also allows for the authentication of the origin of DNS records, making it more difficult for malicious actors to spoof legitimate DNS records.

What is DANE?
DANE is a protocol that builds on the security of DNSSEC by using digital signatures to verify the origin of the DNS record. DANE allows for the authentication of the origin of DNS records, making it more difficult for malicious actors to spoof legitimate DNS records.

How Does DNSSEC and DANE Work in Office 365 Exchange Online?
Office 365 Exchange Online supports DNSSEC and DANE to provide an additional layer of security for DNS. DNSSEC is used to digitally sign DNS records, while DANE is used to authenticate the origin of the DNS records. This ensures that the DNS records returned to the user are authentic and have not been tampered with by a third party.

What Are the Benefits of Using DNSSEC and DANE in Office 365 Exchange Online?
Using DNSSEC and DANE in Office 365 Exchange Online provides a number of benefits. By digitally signing DNS records and authenticating the origin of the DNS records, it is more difficult for malicious actors to spoof legitimate DNS records. This helps to protect users from malicious actors attempting to redirect traffic or perform other malicious activities. In addition, DNSSEC and DANE help to ensure that the DNS records returned to the user are authentic and have not been tampered with by a third party.

Conclusion
Support of DNSSEC and DANE in Office 365 Exchange Online provides an additional layer of security for users by digitally signing DNS records and authenticating the origin of the DNS records. This ensures that the DNS records returned to the user are authentic and have not been tampered with by a third party. By using DNSSEC and DANE, Office 365 Exchange Online users can be sure that their DNS records are secure and have not been tampered with by malicious actors.
