What is threat intelligence?
Threat intelligence is the process of collecting, analyzing, and acting on information about potential cyberthreats that could harm an organization. The data helps security teams understand the tactics used by cybercriminals, enabling proactive defense and faster incident response.
In the context of DMARC, threat intelligence involves analyzing data from receivers of email to identify unauthorized senders and spoofing attempts targeting a domain. This intelligence is critical because attackers often impersonate trusted domains to trick recipients into sharing sensitive information or installing malware.
Why is DMARC important for intelligence?
DMARC is an email authentication protocol that builds on Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to verify that incoming emails are legitimately sent from a business’s domain. When properly implemented, DMARC helps prevent cybercriminals from spoofing a domain.
DMARC’s value goes beyond authentication. It generates two types of reports:
Aggregate reports
Summarizes email authentication results across recipients, showing how many emails passed or failed SPF and DKIM checks.
Forensic reports
Provides detailed information about individual authentication failures, including message headers and sending IP addresses.
These reports are a valuable source of intelligence.
By analyzing them, companies can:
- Detect unauthorized use of their domain
- Identify malicious IP addresses attempting to spoof
- Gain insights into phishing campaigns targeting their brand
How DMARC works
| Step | Description |
|---|---|
| 1. Publish SPF and DKIM records | Define which email servers are authorized to send emails on behalf of the domain |
| 2. Publish DMARC policy | Set a policy to instruct recipient servers how to handle unauthenticated emails (none, quarantine, reject) |
| 3. Receive reports | Collect aggregate and forensic reports from recipient servers detailing authentication results |
| 4. Analyze reports | Use threat intelligence tools built into the Sendmarc platform to interpret data, identify threats, and adjust policies accordingly |
| 5. Enforce policy | Gradually move from monitoring (none) to enforcement (quarantine or reject) to defend against spoofing |
Benefits of threat intelligence for email security
Implementing an intelligence and alerting system offers multiple benefits:
1. Early detection of email threats
A threat intelligence platform enables organizations to detect spoofing and phishing attempts shortly after they occur. Also, by analyzing DMARC reports, businesses can identify unauthorized senders attempting to impersonate their domain, sometimes before recipients are affected.
2. Faster incident response
With real-time alerts and detailed data, security teams can investigate suspicious activity promptly. This accelerates the containment of phishing attacks and reduces the risk of data breaches.
3. Enhanced brand protection
Phishing attacks that spoof a domain can damage a brand’s reputation and affect customer trust. An intelligence platform helps companies proactively defend their brand by identifying impersonation attempts.
