Compatibility and Installation
Tenable Nessus is available for Windows XP, Vista and 7, and Server 2003 and 2008; it is reviewed here on Windows 7 32-bit.
Other versions include the original Linux version for Debian, Fedora, Red Hat, SuSE and Ubuntu, FreeBSD 7, Oracle Solaris 10, and Mac OS X Tiger, Leopard, Snow Leopard and there is even a version for iPhone 4.x, however this is only as a client.
When you download Tenable Nessus, note that there is a 32-bit and 64-bit version available for Windows. Download size is around 10MB.
After installation, the Tenable Nessus Server Manager must be run – at this stage it is time to register the software. Without registration, Tenable won’t let anyone use Nessus, and this is where the choice tales place between signing up for ProfessionalFeed and HomeFeed. One is premium and for business, the other for home use. With the activation code input, Tenable Nessus 4.2.2 will begin downloading the necessary plugins; this can take a while, but once complete the utility is ready to use. Following the setup of a user account, the client application can be used.
