Reducing Alert Fatigue with OpenCTI and RST Noise Control
The RST Noise Control Connector for OpenCTI, developed by RST Cloud, is designed to help cybersecurity professionals filter out benign indicators and suppress noisy indicators, reducing False Positives and improving the efficiency of threat intelligence workflows.
By leveraging RST Cloud’s API, this connector evaluates observables and indicators such as IP addresses, domains, URLs, and hash values to determine their potential relevance in security incidents.
Key Features
Indicators can be automatically validated upon updates, or users can manually initiate checks.
Users can control how OpenCTI score is modified based on API responses (e.g., "Drop" or "Change Score").
Option to unset detection flags when the Noise Control action suggests "Drop" (x_opencti_detection=true|false)
130+ Rule Sets
filter out benign indicators and suppress noise
40GB+ Individual Exceptions
including trusted sources like Microsoft Updates, CDNs, Public DNS, hashes of well-known software, etc
Transparent Reasoning
Users receive context that highlights the reason behind the given verdict
By integrating RST Noise Control with OpenCTI
Reduce Alert Fatigue
OpenCTI is a powerful threat intelligence platform, but managing multiple threat feeds can lead to false positives that waste valuable time of analysts. Minimise unnecessary detections and focus on real threats.
Increase Accuracy
Ensure only relevant and actionable indicators are considered
Improve Efficiency
Save time by eliminating manual review of noisy data
Streamline Workflows
Seamlessly incorporate noise control into OpenCTI for better intelligence management
