Checking Phishing Mail by (SPF, DKIM, and DMARC). 🔰 SPF, DKIM, and DMARC are email authentication protocols that are used to help prevent email fraud and protect email users from receiving fraudulent or malicious emails. ✔ SPF (Sender Policy Framework) is a protocol that allows an email receiver to verify that incoming mail from a domain is being sent from a server authorized by that domain's administrators. - https://lnkd.in/dPYt32EW - https://lnkd.in/dmhVgm3K ✔ DKIM (DomainKeys Identified Mail) is another email authentication protocol that allows email receivers to verify that incoming email messages are authentic and have not been altered in transit. DKIM works by adding a digital signature to the email message header that is generated by the sending mail server. - https://lnkd.in/dp9SryfH - https://lnkd.in/duMSP-FA ✔ DMARC (Domain-based Message Authentication, Reporting & Conformance) is a protocol that builds on SPF and DKIM to provide better email authentication and protection against phishing and other email-based attacks. DMARC allows domain owners to specify how their emails should be handled if they fail SPF or DKIM checks. - https://lnkd.in/dp9SryfH - https://lnkd.in/duMSP-FA 🎁 For more Investigation/Analysis Mail Header: ✔ TOP FREE Online Checking on Phishing Mail - https://lnkd.in/dxXeDQbj ✔ URL shortened Check - https://lnkd.in/d3VS3trE ✔ Phishing Email Analysis - https://lnkd.in/dfscKs4n ✔ Basic of Mail Analysis/Header - https://lnkd.in/dTBtd99R ✔For more content - https://lnkd.in/d2pYU-84 🙏 _________________________________ #informationsecurity #cyberattack #mail #url #attachment #malwareanalysis #threathunting #investigations #socanalyst #soc #phishingattack #awareness #urlshortener #malicious #email
Are you sure that’s all is enough ?
You can analyse your domain’s current SPF, DKIM, DMARC and security score for *free* at https://powerdmarc.com/# also. Additionally, there some some cost effective tools and features that will help you setup the above protocols for your domain even if you do not have strong technical background in cybersecurity PowerDMARC
learndmarc.com is a great free tool to learn about all of them as well and analyze pretty interactive any domain you can send email from. I’m not affiliated to this site in any way.
Important to have, difficult to implement. Many DMARC tools around. An image speaks more than 1000 words.
Great that you share this type of information, there are many companies that continue to be victims of phishing and email spoofing, and just by implementing these verification and authorization mechanisms, they can greatly reduce the risks to these threats. 👏

They basically check to make sure the emails you're getting are legit and not some fake, scammy junk. SPF checks to see if the email is coming from a server that's authorized by the sender's domain admins. DKIM puts a digital signature on the email header to make sure it hasn't been messed with during transit. And DMARC builds on SPF and DKIM to make things even more secure, letting the sender specify what to do with the email if it fails SPF or DKIM checks. It's pretty cool tech, right? 😊 All this starting from bottom when reading.
