Get-KcdDelegationAudit

Business value

The Get-KcdDelegationAudit cmdlet helps administrators identify broken Kerberos constrained delegation (KCD) entries in their Active Directory environment. This can lead to security issues and authentication failures.

• Who uses this: Active Directory administrators and security teams.
• Risks:
  • Broken KCD entries can lead to unauthorized access to sensitive resources.
  • Insecure delegation configurations can compromise the security of the entire organization.
• When a manager cares:
  • When there are reports of authentication issues or suspicious activity related to Kerberos constrained delegation.
  • During regular security audits and compliance checks.

Day-to-day use

To run Get-KcdDelegationAudit, follow these steps:

1. Install the SpnManager module using PowerShell’s Package Manager (e.g., Install-Module -Name SpnManager).
2. Import the SpnManager module in your PowerShell session (e.g., Import-Module SpnManager).
3. Run the Get-KcdDelegationAudit cmdlet with optional parameters, such as -SearchBase to restrict the search scope.

# Example usage:
Get-KcdDelegationAudit -SearchBase "OU=ServiceAccounts,DC=example,DC=com"

Common patterns

• Use -SearchBase to narrow down the search scope for large Active Directory environments.
• Consider running Get-KcdDelegationAudit as part of a regular security audit or compliance check.

What this does in simple terms

The Get-KcdDelegationAudit cmdlet checks Kerberos constrained delegation entries in Active Directory to ensure they point to valid, existing accounts. It reports on any broken targets and provides recommendations for remediation.

Step-by-step recipes

1. Install the SpnManager module.
2. Run Get-KcdDelegationAudit with optional parameters as needed (e.g., -SearchBase).
3. Review the output to identify broken KCD entries and take corrective action.

Data handling

• The cmdlet only reads data from Active Directory and does not modify any existing entries.
• Output is presented in a human-readable format for easy review.

Transit

• Data transmission is secure, as the cmdlet uses standard PowerShell data transport mechanisms.
• No sensitive information (e.g., credentials) is transmitted by default.

At rest

• Data is stored temporarily in memory during execution; no persistent storage occurs.
• Output can be saved to a file for future reference or auditing purposes.

Audit trail

• The cmdlet does not create any audit logs or entries in the target AD environment.
• Users are responsible for maintaining their own audit trails and compliance records.
