Steps to improve np.edu.sg's security grade, ranked by impact.
1
Strengthen email authentication configuration
Email authentication is partially configured for np.edu.sg but has gaps. Actions needed: configure DKIM. Until DMARC enforcement is active, spoofed emails may still reach recipients.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
How to fix this
1
Configure DKIM and publish public key in DNS
2
Verify with: nslookup -type=txt _dmarc.np.edu.sg
