OpenVAS

The Open Vulnerability Assessment System (OpenVAS) is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution.

Founded 1999, Osnabrück, Germany

Why Vulnerability Assessment?

Unnecessary open sharesUnused user accountsUnnecessary open portsRogue devices connected to your systemsDangerous script configurationsServers allowing use of dangerous protocolsIncorrect permissions on important system filesRunning of unnecessary, potentially dangerous

services

ArchitectureCore: Network Vulnerability Tests (NVTs), the security

scanner accompanied with a daily updated feed

OpenVAS Elements:

OpenVAS Software (Server, Client, VulerabilityTests): GNU General Public

OpenVAS Management tools

NVT(Network Vulnerability Tests) Feed service: daily updated tests, unrestricted access

Feature overviewOpenVAS Scanner Many target hosts are scanned

concurrently OpenVAS Transfer Protocol (OTP) SSL support for OTP (always) WMI support (optional)

OpenVAS Manager OpenVAS Management Protocol (OMP) SQL Database (sqlite) for configurations

and scan results SSL support for OMP (always) Many concurrent scans tasks (many

OpenVAS Scanners) Notes management for scan results False Positive management for scan results Scheduled scans Master-Slave Mode to control many

instances from a central one Reports Format Plugin Framework with

various plugins for: XML, HTML, LateX, etc.

Greenbone Security Assistant (GSA) Client for OMP and OAP HTTP and HTTPS Web server on its own (microhttpd), thus no

extra web server required Integrated online-help system Multi-language support

OpenVAS CLI Client for OMP Runs on Windows, Linux, etc. Plugin for Nagios

Sample Test Report

Lab Generation

1. Setting up and Pre-work

Get familiar with the OpenVAS software/Backtrack/CentOS System.

Learn some successful examples using OpenVAS in the past.

Learn some leak patterns.Set up the environment for the test

2. Find targets

Software-Based•Create our own mailbox application•Use the real mailbox application with open source

--Protocol: SMTP(send)/IMAP(receive)/POP3(receive)

Lab Generation

2. Find targets

Web-Based•Open Source Web Browser (EX: The Chromium Projects)•Server with some vulnerabilities (EX: old version CGI)

Lab Generation

3. Penetration Test/Problem solve

•Using OpenVAS to do the test, find some vulnerabilities of the software/web browser/server•Attack the software/web browser/server•Try to fix the vulnerability

Lab Generation

Lab Generation4. Re-test

•Retest using OpenVAS after leaks fixing

•Attack again to check if the vulnerabilities are solved

5. Report

•Give a detailed idea of these assessment

•Give a tutorial of how to use the OpenVAS for the assessment

Lab Generation

Extra Points (if time permitted)

•Develop the mobile platform application to do the whole process above
