DNS Settings to Avoid Email Spoofing and Phishing for Unused Domains
Email spoofing and phishing are two of the most common cyber threats to businesses and organizations. In fact, email spoofing and phishing scams account for over 80% of all cyberattacks! Therefore, it is highly essential for companies to implement the necessary DNS settings to minimize the risks associated with spoofing and phishing.
In particular, unused domains are especially vulnerable to spoofing and phishing because attackers are aware of the lack of DNS setup on these domains. Therefore, it is important for companies to configure the appropriate DNS settings for their unused domains. Here are some recommendations for doing so:
1. Deploy DMARC (Domain-based Message Authentication, Reporting & Conformance)
DMARC is an email authentication system which helps determine if an email message is from the claimed sender or not. It also helps to detect and block malicious emails. DMARC is essential to preventing email spoofing and phishing, so organizations must make sure to deploy it on their unused domains.
2. Use SPF Records
SPF (Sender Policy Framework) records are used to indicate source of messages sent from a domain, helping to prevent spoofing. Organizations should ensure that their SPF records are set up for all unused domains.
3. Enable DKIM (DomainKeys Identified Mail)
DKIM is a digital signature system which allows an organization to digitally sign emails they send out, which helps to prove the messages are from that organization. Implementing DKIM on all unused domains can help stop cyber criminals from sending malicious emails.
4. Implement Sender Identity Framework
SIF (Sender Identity Framework) is similar to DKIM and helps to protect business and organizations from email spoofing and phishing.
By configuring the relevant email authentication systems such as DMARC, SPF, DKIM and SIF, organizations can greatly reduce their risk of email spoofing and phishing on their unused domains. It is vital for businesses to ensure that these DNS settings are correctly implemented to protect their organizations from cyber threats.
