NeXpose from Rapid7 is a unified vulnerability solution that scans networks to identify the devices running on them and to probe these devices for vulnerabilities. It analyzes the scan data and processes it for reports.
The vulnerability checks in NeXpose identify security weaknesses in all layers of a network computing environment, including operating systems, databases, applications, and files. NeXpose can detect malicious programs and worms, identify areas in your infrastructure that may be at risk for an attack, and verify patch updates and security compliance measures.
With the NeXpose Community Edition you are able to scan up to 32 IP addresses in your network at the same time. This workshop will show you, how to install NeXpose Community Edition on Backtrack 4.
Downloading the software
Download Nexpose Community Edition form here:
http://www.rapid7.com/vulnerability-scanner.jsp
After accepting the End User License Agreement you will get an e-mail with the download instructions and the product key which allows you to use this version for commercial and private scans. Use md5sum according to the instructions sent, which helps to ensure that installers are not corrupted during download.
The following Nexpose installers are available:
- NeXpose for Linux – 32-bit
- NeXpose for Linux – 64-bit
- NeXpose for Windows – 32-bit
- NeXpose for Windows – 64-bit
Please keep in mind that Rapid7 does not support installation on Windows XP because of an issue related to this operating system sending packets over raw sockets. For that reason, Windows users should use MS Windows Server 2003 SP2/ Server 2003 R2.
The following Linux Distributions are supported:
- SUSE Enterprise Linux 9
- Red Hat Enterprise Linux 4
- Fedora 9 or later
- Debian 4.0 or later
- CentOS 4 or later
- Ubuntu 7.10 or later
As penetration testers we are already using Backtrack 4. Make sure to have Backtrack 4 installed on your hard disk.
Installation
First things first: Store the downloaded file (NeXposeSetup-Linux32.bin) in the directory /tmp and set the correct permissions.
cd /tmp
chmod 755 NeXposeSetup-Linux32.bin
Additionally we need some packages that must be installed on Backtrack 4 first. Make sure to have a proper Internet connection and to use the following commands to update Backtrack 4 and to install the necessary packages:
apt-get update
apt-get upgrade
agt-get dist-upgrade
agt-get install libstdc++5
agt-get install xvfb
agt-get install xfonts-base
agt-get install xfonts-75dpi
agt-get install xserver-xorg
agt-get install libxtst6
agt-get install libxp6
agt-get install libxt6
Run the installer like this and follow the instructions. Make sure to install NeXpose in the default directory /opt/rapid7/nexpose.
cd /tmp
./NeXposeSetup-Linux32.bin
According to your hardware, the installer needs some time to copy and configure everything.
During this process you must create a NeXpose account for the NeXpose administrator. Choose a username and password that is secure and easy to remember. You will need to use this account to configure the server after installing it.
Preparing the first run
You can run Nexpose first time using the following commands:
cd /opt/rapid7/nexpose/nsc/
./nsc.sh
The script will prepare the database and will import the vulnerability categories and data. According to your hardware and Internet connection, this will take some time.
Let’s first install NeXpose as a daemon. In this case we have to copy the nexposeconsole.rc file to the /etc/init.d directory, and give it the daemon name nexpose:
cp /opt/rapid7/nexpose/nsc/nexposeconsole.rc /etc/init.d/nexpose
chmod 755 /etc/init.d/nexpose
If you like to start the daemon automatically when the operating system starts, use the following command:
update-rc.d nexpose defaults
I prefer to start, stop and restart the daemon manually. For that reason I’m using the following commands:
/etc/init.d/nexpose start
/etc/init.d/nexpose stop
/etc/init.d/nexpose restart
The NeXpose Security Console communicates with NeXpose Scan Engines to start scans and retrieve scan information. All exchanges between the console and scan engines occur via encrypted SSL sessions. Use your favorite browser and the following URL:
https://localhost:3780
You will possibly get an error message because of the security certificate. In this case just add an exception. You also should allow Java scripts to work if you have the “NoScript” addon installed.
If you don’t like NeXpose or you want to quit the evaluation, just uninstall it like this:
cd /opt/rapid7/nexpose/_uninst
./uninstaller.bin
rm –Rf /opt/rapid7/nexpose
