How SIRP Solves the Use Case

Accelerate Detection, Streamline Response
With the SIRP Restricted Country VPN Login Detection and Response playbook, you can automate every step of the security workflow-receiving alerts from your SIEM system, pinpointing geolocations, conducting reputation checks, and blocking malicious IPs in record time. Instead of painstakingly correlating these details manually, you’ll see them consolidated into a real-time dashboard, empowering security analysts to take immediate, data-driven action. By cutting down on tedious tasks, SIRP helps your team respond swiftly and focus on high-impact threats instead of benign anomalies.

Technologies Involved

1. IPInfo
   Harnesses reliable geolocation data for every incoming IP address, quickly revealing if a suspicious login attempt originates from a blacklisted or restricted region.
   
2. AlienVault OTX
   Offers critical reputation analysis to assess whether an IP is already flagged as a known threat, enabling you to block malicious sources before they gain a foothold.
   
3. Juniper SRX Firewall
   Automates IP blocking based on your organization’s policies. If an IP is confirmed malicious, the firewall kicks into gear to cut off potential intruders instantly.
   
4. SIRP
   Centralizes notifications, manages alert severity, updates dispositions, and streamlines incident management-all from a unified platform.
   
   

The SIRP Playbook & How It Works

1. Suspicious VPN Alert Trigger
   Your SIEM is configured to issue “Suspicious VPN Login” alerts for any login originating from restricted countries or high-risk IP ranges. As soon as SIRP receives this alert, the playbook springs into action.
   
2. Instant IP Geolocation
   The playbook automatically checks the IP address with IPInfo to confirm its origin. If the location matches your organization’s restricted list, the system flags it for further analysis.
   
3. Reputation Checks
   Next, AlienVault OTX evaluates whether the IP is associated with malicious activity. Any negative flags here instantly escalate the alert for potential blocking.
   
4. Automated Firewall Blocking
   If the IP is confirmed malicious, SIRP instructs the Juniper SRX Firewall to block access immediately. Additionally, the alert’s severity is set to “High,” ensuring maximum visibility. A quick notification is then sent to analysts, who can take further steps like confirming the legitimacy of the VPN user or disabling the VPN ID.
   
5. Investigation for Clean IPs
   If the IP isn’t malicious but comes from a suspicious region, the alert is labeled “Investigation” and severity remains high. Analysts receive a prompt to confirm user activity, preventing legitimate employees or partners from being inadvertently blocked.
   
6. Continuous Alert Management
   Every action-firewall block, status update, severity change, or analyst notification-is tracked within the playbook. This ensures a thorough audit trail and maintains full visibility into any escalations or follow-ups.
   

What You Achieve by Solving This Use Case

1. Accelerated Response Time
   The moment suspicious activity is detected, the playbook automates geolocation checks and firewall blocking, slashing critical response windows.
   
2. Reduced Analyst Workload
   Rather than chasing down every abnormal login, analysts focus only on high-risk events identified through automated checks. Routine tasks are handled behind the scenes, freeing up your team’s bandwidth.
   
3. Enhanced Security Posture
   By immediately isolating or blocking malicious IPs, you stop unauthorized access at the source. This proactive stance drastically reduces the risk of data breaches and system compromises.
   
4. Streamlined Coordination
   The entire response process-investigation, blocking, severity changes-plays out in a centralized platform. Different teams can collaborate effectively, ensuring no alert slips through the cracks.
   
5. Customizable and Scalable
   Easily adapt the playbook to integrate with additional geolocation services or alternative firewalls. Whether you’re operating a small environment or a global enterprise, SIRP scales right along with you.
   

Conclusion
By automating every step-from geolocation and reputation checks to immediate firewall blocking-SIRP’s Restricted Country VPN Login Detection and Response playbook takes the guesswork out of identifying and handling high-risk VPN logins. Real-time alerts, rapid escalation, and centralized visibility ensure that your security team is always in control, confidently locking out unauthorized users the moment they try to slip under the radar.

Don’t leave your organization vulnerable to stealthy intrusion attempts. Embrace the power of automated detection and response, and give your team the speed and clarity they need to safeguard your network against the ever-growing tide of cyber threats.
