• Incident response and remediation

Ensure Email Authentication is correctly setup

• SPF, DKIM, and DMARC help authenticate email senders by verifying that the emails came from the domain that they claim to be from. These three authentication methods are important for preventing spam, phishing attacks, and other email security risks.
• Verify where DMARC emails are being sent to for troubleshooting purposes
• all authorized mail providers are properly being routed to customers and not going to junk mail
• Determine if any domains are spoofing as you

Authentication Enhancement:

• Implement multi-factor authentication (MFA) and email authentication protocols such as SPF, DKIM, and DMARC to bolster email security.
• Enable MFA, configure SPF/DKIM/DMARC settings, and conduct user training on secure email practices.

Log Analytics Integration:

• Integrate email logs into Microsoft Sentinel for advanced threat detection, anomaly detection, and incident investigation.
• Configure log ingestion, create custom dashboards for email security, and set up automated alerts for suspicious activities.

Continuous Monitoring and Incident Response:

• Monitor email traffic in real-time, analyze logs for security events, and orchestrate incident response workflows within Microsoft Sentinel.
• Establish monitoring rules, define incident response playbooks, and conduct regular drills to ensure swift response to email security threats.
