Wisdom – DMARC Deployment

Deploy SLOWLY, We strongly recommend ramping up DMARC use slowly by employing these policies in this order. First, monitor your traffic and look for anomalies in the reports, such as messages that are not yet being signed or are perhaps being spoofed. Then, when you’re comfortable with the results, change the TXT record policy setting […]

What is DMARC and what are its advantages?

This article is part of Explained Simply Series, A series that aims to explain complex terminologies in a short & concise manner. DMARC, which stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication protocol. It builds on the widely deployed SPF and DKIM protocols, adding a reporting function that allows senders and receivers […]

DKIM KEYS Consideration

Messages with DKIM signatures use a key to sign messages. Messages signed with short keys can be easily spoofed (see http://www.kb.cert.org/vuls/id/268267), so a message signed with a short key is no longer an indication that the message is properly authenticated. To best protect  users, Gmail will begin treating emails signed with less than 1024-bit keys […]

DKIM Simplified

DomainKeys Identified Mail (DKIM), is a mechanism that allows verification of the source and contents of email messages. Using DKIM, sending domains can include a cryptographic signature in outgoing email messages. A message’s signature may be verified by any (or all) MTAs (mail servers) during transit and by the Mail User Agent (MUA) upon delivery. […]

DMARC : Need of enforcement in financial institutes

Is this piece of Email legitimate or just a really good fake mail trying to deceive you? E-mails perpetuate a lot of attacks and are involved in more than 90% of malware and spoofing attacks. When there was no DMARC, organizations found it really tough to figure out if the mail is legit or not […]

What is DKIM? All you need to know about DKIM

Domain Keys Identified Mail (DKIM) is a technological norm that helps deter spam, spoofing, and phishing from email senders and recipients. This is a type of email authentication that allows an individual to assert accountability for a message in a manner that the receiver may validate. DKIM uses a “public-key cryptography” approach to verify that […]
