![]() This is because the default for a new scan is to scan 30 hosts concurrently with up to 10 Network Vulnerability Tests (NVT) per host. I tried a few different runs trying to debug what was going on before I realized the Pi was just running out of resources and killing random processes (the scanner, the website, firefox tabs, terminals). My home network has about 25 devices on it and the initial scan task died before it got even to 2%. The task wizard can take a CIDR address for a target: 192.168.16.0/24. Full network scan & limitationsĪfter validating a single IP scan worked well wanted a full home network scan. Not great but not too shabby if you have a focused target to check. The full scan of a single system took about two hours. ![]() Patience is required after a click while you wait for the action to be processed and the page rendered. It became quickly apparent that the RPi struggles to provide the OpenVAS administrator website (Greenbone Security Assistant). I did this process using the RPi with Kali as a desktop workstation. Doing a single system scan worked well for me, it took a long while to get through all 60,000 Network Vulnerability Tests, but did complete and allow me to review the report. Use the wizard to create a scan for your target system using it’s IP or DNS name. Scans -> Tasks -> Purple Wand Icon -> Task Wizard Once web GUI is up you can create a new scan job using the Task Wizard found via: Openvas-start # should auto launch your web browser grab htop (for watching system metrics) & lsof (for opevas).delete part 2, recreate - use same start point ( pay attention) & max size.resize the root filesystem (8GB default size not enough for OpenVAS).apt update & apt upgrade -yes & apt dist-upgrade -yes.My basic checklist I ran through to get a happy OpenVAS on my RPi using a 16GB SD card: There were a few false starts as I learned a few gotchas of both the Kali linux and OpenVAS. The Install OpenVAS for Broad Vulnerabilty Assessment guide by Barrow on Null-Byte Wonder How To is still relevant as of May 2018 for the RPI Kali 2018.02 as put out by the Offensive Security team. Turns out it can work for single host scanning but has some limitations for larger network scans. There are a variety of open source and commercial products for doing vulnerability scans but I decided to focus efforts on OpenVAS a well recognized helpful tool for adminstrators needing to identify potential security issues on their networks.Īs part of the effort I wanted to evaluate the use of this tool on a Raspberry Pi. Find open services and detect if they had known vulnerabilities. The goal was to look at the network like an attacker would. This would act as one component of a larger activity to ensure a secure system for credit card handling. OpenVAS + Kali + Raspberry Pi = Vulnerability ScannerĪ recent project needed a vulnerability scanner that could be deployed to a variety of clients and their networks to do a vulnerability scan.
