PyMISP CISA Alerts

The aim of this tool is to provide a simple and automated way of gathering alerts about vulnerabilities and some threats regarding ICS/SCADA. The tool uses the feedparser Python library for consuming RSS feed published by CISA, which publishes alerts regarding this topic regularly.

The alerts gathered will be correlated to a keywords list(software.txt) in order to be aware of the vulnerabilities that you want to monitor. If any of the alerts contain one or more keywords stored in the software.txt file, the alerts will be sent to the configured MISP instance.

National Cyber Awareness System (NCAS)

The tool gathers information from the followings sources within the CISA NCAS.

• Bulletins: Weekly summaries of new vulnerabilities (including patch information if available).
• Advisories: Timely information about current security issues, vulnerabilities and exploits.

MISP

The alerts containing any of the keywords stored in the software.txt file will be sent to the configured MISP instance. The events created will contain the tag "vulnerability".

Configuration

In order to send only relevant threats and vulnerabilities to your MISP instance, you will have to create a list of software products that you want to monitor. This list will be stored in the software.txt file (config/config_files/). For instance, imagine that you want to stay up to date about vulnerabilities in AXIS Q16 cameras and Siemens S7-1200 PLCs, you will add to the software.txt file the following elements:

• AXIS Q16
• Siemens S7-1200

Besides, the software.txt file, there's a SQLite database (config->sqlite) for storing the entries that you already have analysed.

Using the tool

Gathering only Vulnerability Bulletins from CISA reports.

python main.py --vulns 

Gathering only ICS threats from CISA reports.

python main.py --threats

Gathering entries from ICS threats and Vulnerability Bulletins reported by CISA.

python main.py --full

Using proxy for MISP instance connection.

python main.py --proxy
