FAQ - Frequently Asked Questions

What is the ACN Cyber Taxonomy (TC-ACN)?

The ACN Cyber Taxonomy (TC-ACN) is an official guide published by the National Cybersecurity Agency (ACN), the central Italian authority for NIS2. It aims to provide interested parties with tools to characterize a cyber event through 219 attributes, to specify its nature and provide a granular description during information exchanges. It defines a common and standardized language for classifying and describing IT security events.

How does this TC-ACN vector generator work?

This tool guides you in characterizing a computer incident according to the Taxonomy of the National Cybersecurity Agency (TC-ACN). The tool is based on the ACN guidelines of 31/07/2024 and subsequent updates. Select the parameters related to your incident in the 4 macro categories (Baseline Characterization, Threat Type, Threat Actor, Additional Context) and automatically generate the cyber incident vector in the standardized format.

What are the characterization categories?

The generator organizes characterization into 4 macro categories:

Baseline Characterization (BC) - Mandatory basic incident parameters
Threat Type (TT) - Type of threat identified
Threat Actor (TA) - Threat actor characteristics
Additional Context (AC) - Additional context and specific details

Where can I find the official references?
