Manual Effort & User Lockouts
The organization’s remote desktop gateway faced a high volume of failed login attempts consistent with a brute-force attack. Even after initial tuning reduced attempts from 1,000+ to approximately 100, the activity continued to create user lockouts and operational disruption.
The client needed a reliable way to identify the true source IP addresses and block them quickly without impacting legitimate remote access.
- Assess:Analyzed security logs and tested multiple event sources to find a reliable indicator of attack activity.
- StrategyBuild an automated process to detect attacker IPs from remote access logs and maintain a bad IP list.
- ImplementCreated PowerShell scripts to add offending IPs to the list and automatically update a Windows Firewall block rule. Tested and validated the solution.
- SupportScheduled the automation to run continuously, ensuring new threats are blocked without manual intervention.
The result is a repeatable, hands-off process that keeps attackers out and legitimate users in.
