Introduction:
Cyber insurance is no longer a guaranteed safety net—companies must prove they’ve implemented basic security measures like multi-factor authentication (MFA) to qualify for coverage. A recent case in Hamilton, Canada, saw $5 million in claims denied due to a lack of MFA, highlighting the growing scrutiny insurers now apply.
Learning Objectives:
- Understand why insurers are denying claims over missing MFA.
- Learn how to audit and improve your organization’s login security.
- Discover key cybersecurity controls insurers now require.
1. Why MFA Is Non-Negotiable for Cyber Insurance
Verified Command (Linux/Windows):
Check if MFA is enforced in Microsoft Entra ID (formerly Azure AD):
Get-MgPolicyAuthenticationStrengthPolicy -PolicyId "authenticationStrengthPolicies" | Select-Object -Property DisplayName, Requirements
Step-by-Step Guide:
1. Open PowerShell as an admin.
- Install the Microsoft Graph PowerShell module if not already present:
Install-Module -Name Microsoft.Graph -Force
3. Connect to Microsoft Graph:
Connect-MgGraph -Scopes "Policy.Read.All"
4. Run the command above to verify MFA policies.
What This Does:
This checks if MFA is configured in your Azure AD tenant, a critical requirement for insurers.
- How to Enforce MFA Across Your Organization
Verified Command (Microsoft 365/Azure AD):
Enable MFA for all users via Conditional Access:
New-MgIdentityConditionalAccessPolicy -DisplayName "Require MFA for All Users" -State "enabled" -Conditions @{ Applications = @{ IncludeApplications = "All" }; Users = @{ IncludeUsers = "All" } } -GrantControls @{ Operator = "OR"; BuiltInControls = "mfa" }
Step-by-Step Guide:
- Ensure you have Global Admin or Security Admin permissions.
- Run the command to enforce MFA for all logins.
- Verify in the Azure Portal under Security > Conditional Access.
Why This Matters:
Insurers increasingly demand proof of MFA enforcement—this policy ensures compliance.
3. Auditing Login Security Gaps (Windows/Linux)
Verified Command (Linux):
Check for SSH password authentication (should be disabled):
grep -i "PasswordAuthentication" /etc/ssh/sshd_config
Step-by-Step Guide:
1. Open /etc/ssh/sshd_config in a text editor.
2. Ensure `PasswordAuthentication no` is set.
3. Restart SSH:
sudo systemctl restart sshd
What This Does:
Weak SSH authentication is a common attack vector—insurers may deny claims if found.
4. Detecting Phishing-Prone MFA Bypasses
Verified Command (Microsoft Defender for Office 365):
Check for suspicious MFA bypass attempts:
Get-MgSecurityAlert -Filter "Category eq 'Phishing' and Status eq 'New'" | Select-Object , CreatedDateTime
Step-by-Step Guide:
1. Ensure Defender for Office 365 is enabled.
- Run the command to detect recent phishing attempts.
- Investigate alerts in the Microsoft 365 Defender portal.
Why This Matters:
Insurers now scrutinize whether MFA is phishing-resistant (e.g., FIDO2 keys).
5. Cloud Hardening: Ensuring AWS/GCP MFA Compliance
Verified Command (AWS CLI):
Enforce MFA for AWS root accounts:
aws iam create-account-password-policy --minimum-password-length 12 --require-symbols --require-numbers --require-uppercase-characters --require-lowercase-characters --allow-users-to-change-password true --max-password-age 90 --password-reuse-prevention 24
Step-by-Step Guide:
1. Install and configure AWS CLI.
- Run the command to enforce strong password policies.
- Enable MFA for all IAM users via the AWS Console.
What This Does:
AWS security best practices are now a baseline for cyber insurance approval.
What Undercode Say:
- Key Takeaway 1: Cyber insurers are no longer rubber-stamping claims—MFA gaps = denied payouts.
- Key Takeaway 2: Companies must prove security controls, not just claim them on paper.
Analysis:
The Hamilton breach denial signals a turning point—insurers are enforcing stricter security validation. Businesses must treat cybersecurity as a financial risk, not just an IT issue. Expect more insurers to mandate phishing-resistant MFA, endpoint detection, and encrypted backups before approving coverage.
Prediction:
By 2026, 50% of mid-sized firms will face coverage denials for failing basic security audits. Companies that proactively implement zero-trust architecture and continuous monitoring will secure better premiums, while others risk financial ruin from uninsured breaches.
Final Note:
If you have cyber insurance, audit your security posture now—before your insurer does it for you.
