Redaction Library

Updated 4 months ago by Elvis Hovor

TruSTAR offers the ability to redact, or remove, information from a report. This redaction library is powered by a redaction algorithm that features:

  • Categorical redaction
  • Wildcard matching
  • Optimization for large datasets

For details on how to edit the Redaction Library, see Managing the Redaction Library.

How It Works

TruSTAR’s Redaction feature operates on two inputs:

  • A TruSTAR Report
  • A map of redaction descriptors known as the Redaction Library

When a report is submitted, TruSTAR uses the Redaction Library to delete the terms you have specified for removal. The Redaction algorithm programmatically strips the terms from every part of the report, including the metadata.

You can add or delete terms to redact whenever you want.

TruSTAR Incident Report

Technically, an incident report is a map-like data structure that contains both metadata about the report and the report contents. For example, here is a simplified version of what an incident report looks like in TruSTAR Station.

Map {
metadata: Map {
title: "Network Intrusion Detected",
region: "North America"
},
content: "Network intrusion was detected at our branch in..."
}

Redaction Library

The redaction library stores all the terms you want to delete from new reports. A simple redaction library might look like this:

Map {
company-name: List [
"Superb Security Corp",
"Superb Subsidiary"
],
ip-address: List [
"8.8.8.8"
],
email-address: List [
"*@superb-security.co"
]
}

This sample Redaction Library defines a number of things to redact from reports:

  • Company name "Superb Security Corp" and the name of the subsidiary "Superb Subsidiar"
  • An IP address that should be kept private ("8.8.8.8")
  • Every email address that ends in "@superb-security.co"
