Many CISOs commit the mistake of transitioning to Reject mode for DMARC without proper analysis. Their "Reject' mode transition fails because of the following:
?? Poor internal communication about policy
?? Misconfigured SPF/DKIM records
?? Overly Aggressive Policies
?? Using legacy systems
?? No policy finetuning
?? Lack of monitoring
Managed DMARC is the answer.
7 things that make up Managed DMARC:
??Threat detection and monitoring.
??Review, reporting and analysis.
??Alignment and authentication.
??Improved communication.
??DMARC record sanity.
??Policy enforcement.
??Incident response.
Managed DMARC best-practices.
- Start in 'Monitor' Mode: Begin with DMARC in monitoring mode for gradual adjustment.
- Authenticate Legitimate Senders: Identify and authenticate authorized email sources.
- Gradual Policy Enforcement: Implement 'Reject' mode progressively to avoid disruptions.
- Regularly Review Reports: Analyze DMARC reports consistently for insights and improvements.
- Utilize DKIM and SPF: Leverage DKIM and SPF in conjunction with DMARC for robust protection.
- Engage with Industry Experts: Collaborate with Managed DMARC professionals for guidance and best practices.
- Educate Stakeholders: Ensure all team members understand the importance of DMARC for security.
