ADAudit Plus: The Complete Guide to Active Directory AuditingActive Directory (AD) is the backbone of identity and access in many organizations. Securing and monitoring AD is critical because misconfigurations, unauthorized changes, or compromised accounts can expose sensitive resources and disrupt business operations. ADAudit Plus is a purpose-built solution for real-time monitoring, auditing, and reporting of Active Directory, Group Policy, file servers, Azure AD, and more. This guide explains what ADAudit Plus does, why it matters, how it works, key features, deployment considerations, common use cases, and best practices for getting the most from the product.
What is ADAudit Plus?
ADAudit Plus is a comprehensive Active Directory auditing and monitoring tool that captures changes and activities across AD, file servers, domain controllers, Group Policy, and Azure AD. It collects logs, correlates events, and delivers ready-made reports, alerts, and compliance-ready evidence to help administrators detect suspicious activity, ensure configuration hygiene, and meet regulatory requirements.
Why AD auditing matters
- AD controls user authentication and access to critical systems. Unauthorized changes (e.g., adding a user to Domain Admins) can lead to privilege escalation.
- Native Windows logs are detailed but noisy and hard to interpret at scale. A dedicated auditing tool makes it feasible to consistently monitor, filter, and analyze AD events.
- Regulatory frameworks (PCI-DSS, HIPAA, SOX, GDPR) often require proof of log collection, retention, and change-tracking for privileged accounts and security-relevant configurations.
- Rapid detection and response reduce dwell time for attackers, limit damage from insider threats, and support forensic investigations after incidents.
Key components and scope
ADAudit Plus typically covers the following areas:
- Active Directory (user, group, OU, computer account changes)
- Domain Controllers (logon/logoff, authentication failures, Kerberos events)
- Group Policy Objects (GPO creation, modification, deletion)
- File Server Auditing (file/folder access, permission changes)
- Azure AD (user and role changes, sign-ins integration)
- LDAP and AD Replication monitoring
- Security and compliance reports, alerts, and dashboards
How ADAudit Plus works (high-level)
- Data collection: ADAudit Plus reads Windows Security Event Logs from Domain Controllers, member servers, and file servers. It can use event subscription, agentless collection, or agents depending on architecture and scale.
- Normalization and parsing: Raw events are parsed into structured records (who, what, when, where).
- Correlation and enrichment: Events are correlated (for example, linking a privileged group change with a specific administrator account) and enriched with contextual data like device names, IP addresses, and AD object attributes.
- Storage and search: Parsed events are stored in the ADAudit Plus repository, indexed for fast search and historical reporting.
- Reporting and alerting: The product provides prebuilt reports mapped to compliance standards, real-time alerts for critical events, and dashboards for operational visibility.
Deployment options and architecture
- Small deployments: ADAudit Plus can be installed on a single server (on-premises) that collects logs from Domain Controllers and servers. Agentless collection and Windows Event Forwarding (WEF) are common.
- Large/enterprise deployments: Use a dedicated collector architecture, distributed deployment, or agents to scale collection across many domain controllers and file servers. Consider high-availability and backup for the ADAudit Plus database.
- Cloud integrations: ADAudit Plus supports Azure AD auditing by integrating with Azure AD sign-in and audit logs, pulling them into the same reporting interface.
Core features and capabilities
- Real-time change and activity monitoring with alerts (e.g., changes to Domain Admins, GPOs, service accounts)
- Prebuilt compliance reports (PCI-DSS, HIPAA, SOX, GDPR, ISO) and the ability to customize reports
- File server auditing for file/folder access and permission changes, with search and filter capabilities
- User logon/logoff tracking and failed authentication reporting
- GPO change tracking and version history
- Object modification history (who changed what and when)
- Dashboards and executive-level summaries
- Forensics-capable search with filtering by user, object, event type, time range
- Role-based access control (RBAC) for report access and alert management
- Alert escalation and notification via email, SMS, or integration with SIEMs and ticketing tools
- Ability to export reports and scheduled report delivery
Common use cases
- Detecting unauthorized privilege escalations (e.g., membership changes in privileged groups)
- Monitoring sensitive account activity (service accounts, privileged administrators)
- Demonstrating compliance through scheduled reports and audit trails
- Investigating suspicious logins or access patterns after alerts
- Tracking GPO changes that might weaken security posture
- Auditing file server access to detect data exfiltration or improper access
- Integrating AD events into a broader security operations workflow or SIEM
Example alerts you should enable
- Changes to Domain Admins, Enterprise Admins, or other privileged groups
- Creation or modification of privileged user accounts or service accounts
- Account lockouts and repeated failed authentication attempts
- Unexpected modifications to GPOs
- Changes to ACLs on sensitive files and folders
- New computer accounts being added to the domain
- Changes to trust relationships or domain controllers
Reporting and compliance
ADAudit Plus comes with dozens of prebuilt reports tailored to major compliance frameworks. Examples include:
- User and Privileged Account Reports (creation, deletion, membership changes)
- Logon Activity and Failed Logon Reports
- GPO Change Reports and GPO Audit History
- File Access and Permission Change Reports
- Audit Trail and Object Access Reports mapped to compliance controls
Customize report schedules and retention durations to meet policy and audit requirements. Export formats typically include PDF, CSV, and XLS.
Best practices for using ADAudit Plus
- Enable auditing for relevant Windows events at the domain controller and file server level. Ensure Windows audit policies are configured to capture account and directory changes.
- Centralize collection using Windows Event Forwarding or agents for reliability and reduced network noise.
- Define and tune alerts to reduce false positives — focus on high-risk events first (privileged group changes, failed admin logons).
- Integrate with your SIEM or ticketing system for incident response workflows.
- Use RBAC to restrict who can view sensitive audit reports.
- Regularly review and update the list of monitored objects and sensitive groups as your environment changes.
- Archive and retain logs per legal/compliance requirements; verify backup and high-availability plans for the ADAudit Plus database.
Limitations and considerations
- Licensing and cost: ADAudit Plus is commercial software; evaluate licensing costs against features and scale.
- Storage: Long-term retention of detailed audit logs can require substantial storage; plan disk capacity and retention policies.
- False positives: Like any monitoring system, misconfigurations or overly broad rules can lead to alert fatigue. Proper tuning is essential.
- Privacy and data handling: Audit logs contain sensitive data; apply least-privilege access controls and encryption for stored logs where possible.
Integrations and ecosystem
- SIEM platforms (forward alerts/events to SIEMs for correlation)
- Ticketing systems (create incidents automatically from critical alerts)
- Email/SMS/Teams/Slack for alert delivery
- Azure AD and hybrid identity environments for unified identity auditing
Getting started checklist
- Identify domain controllers, file servers, and Azure AD tenants to monitor.
- Install ADAudit Plus on a Windows server with recommended sizing for your environment.
- Configure event collection (WEF, agents, or direct polling) and validate event flow.
- Enable key Windows audit policies required for AD change and object access events.
- Import or configure sensitive groups, accounts, and file paths to prioritize.
- Enable prebuilt compliance reports and schedule initial report deliveries.
- Tune alert thresholds and test alert delivery methods.
- Integrate with SIEM/ticketing if required and set RBAC for administrators.
Conclusion
ADAudit Plus is a focused solution for Active Directory and identity auditing that helps organizations gain visibility into critical directory changes, access events, and potential security incidents. When deployed and tuned correctly, it streamlines compliance reporting, accelerates investigations, and strengthens overall identity security posture.
