Enabling DNSSEC and DANE in Office 365 Exchange Online

Enhancing Security with Exchange Online and DNSSEC
Modern internet security is a top priority of businesses, and Exchange Online is now offering a new way to secure email communications: DANE and DNSSEC. This article will explain what DANE and DNSSEC are and how they can enhance the security of your Exchange Online environment.

What is DANE?
DANE stands for Domain Name System-Based Authentication of Named Entities. It is a security protocol that allows a domain name to be validated and authenticated. This is done by digitally signing the domain name and its associated records. DANE is a protocol that provides a secure way for domain owners to authenticate their domain name and the associated records. This is done by using the DNSSEC protocol.

What is DNSSEC?
DNSSEC stands for Domain Name System Security Extensions. It is an authentication protocol that is used to secure domain name records. It is a set of protocols that provide digital signatures for domain name records. These digital signatures are used to verify the authenticity of the domain name records. DNSSEC is used to ensure that the data associated with a domain name is authentic and unaltered.

How Does DANE and DNSSEC Enhance Security of Exchange Online?
By using DANE and DNSSEC, Exchange Online can authenticate domain names and the associated records. This makes it more difficult for malicious actors to alter or spoof domain name records. With the use of DANE and DNSSEC, the authenticity of the domain name and its associated records can be verified. This means that malicious actors cannot alter the domain name or its associated records without being detected.

In addition, DANE and DNSSEC can help protect against email spoofing. Email spoofing is when a malicious actor sends emails that appear to be from a legitimate source. By using DANE and DNSSEC, the authenticity of the domain name and its associated records can be verified. If a malicious actor attempts to spoof an email address, the authentication process will detect the deception.

Conclusion
DANE and DNSSEC are important protocols for enhancing the security of Exchange Online. By using DANE and DNSSEC, Exchange Online can authenticate domain names and the associated records. This makes it more difficult for malicious actors to alter or spoof domain name records. In addition, DANE and DNSSEC can help protect against email spoofing. With the use of DANE and DNSSEC, Exchange Online can provide a secure environment for email communications.
