Integrating Total Access Control with Your SIEM Solution

Security Information and Event Management (SIEM) platforms are essential for correlating logs and detecting sophisticated attacks. Integrating Total Access Control with your SIEM amplifies visibility and accelerates response. This guide walks you through the integration process for popular SIEM tools such as Splunk, Microsoft Sentinel, and Elastic Stack.

Why Integration Matters

Standalone access control logs provide valuable data, but when combined with network, endpoint, and threat intelligence feeds, you gain:

• Contextual alerts that tie user activity to broader threat patterns.
• Automated response actions—e.g., session termination upon suspicious behavior.
• Compliance‑ready audit trails that are searchable across the organization.

Prerequisites

Before you begin, ensure you have:

• Administrator access to Total Access Control.
• API credentials (client ID and secret) for the SIEM.
• Network connectivity between the access control server and the SIEM collector.

Common Integration Methods

Syslog Forwarding

Configure Total Access Control to export logs in syslog format to your SIEM’s listening endpoint.

REST API Ingestion

Use the platform’s RESTful API to pull event data on a scheduled basis.

Webhook Push

Set up a webhook that pushes critical events (e.g., failed MFA, privileged access) in real time.

Step‑by‑Step for Splunk

1. Log into the PortSys TAC admin console and navigate to Integrations → Syslog.
2. Enter the Splunk syslog server IP and port (default 514).
3. Choose the event categories you wish to forward (Authentication, Policy Change, etc.).
4. Save the configuration and restart the logging service.
5. In Splunk, create a new data input for UDP/TCP syslog on the matching port.
6. Apply the provided source type secureaccess:accesslog and index it to access_control.
7. Build a dashboard using Splunk’s Search Processing Language (SPL) to visualize login trends and anomalous activity.

Step‑by‑Step for Microsoft Sentinel

1. In Azure Portal, go to Microsoft Sentinel → Data Connectors → Custom Log.
2. Generate a new Log Analytics workspace if you don’t have one.
3. Copy the workspace ID and primary key.
4. Back in PortSys TAC, select Integrations → REST API and input the Sentinel endpoint URL:

https://{workspace-id}.ods.opinsights.azure.com/api/logs?api-version=2016-04-01

5. Configure the JSON payload to match Sentinel’s required schema (timestamp, user, action, result).
6. Test the connection; on success, enable the connector.
7. Use Sentinel’s built‑in analytics rules to generate alerts on high‑risk access events.

Step‑by‑Step for Elastic Stack (ELK)

1. Deploy Filebeat on the same host as the Total Access Control server.
2. Configure Filebeat to watch the access log file (e.g., /var/log/secureaccess/access.log).
3. Set the output to your Elasticsearch cluster.
4. In Kibana, create an index pattern secureaccess-* and build visualizations for authentication failures and policy changes.

Best Practices for Effective Integration

• Normalize timestamps: Ensure all logs use UTC to avoid correlation errors.
• Filter noise: Forward only high‑value events to reduce SIEM storage costs.
• Secure transport: Use TLS for API and webhook communications.
• Regularly review parsers: Keep field mappings up‑to‑date as product features evolve.

Conclusion

By connecting Total Access Control to your SIEM, you turn raw authentication data into actionable intelligence, enhance threat detection, and streamline compliance reporting. Follow the steps above to achieve a unified security monitoring architecture.
