Pre-Installation

To ensure a streamlined installation process, it is important to ensure that the appropriate hardware, software, and

licensing requirements are in place prior to installation.

Hardware requirements

Enterprise networks can vary in performance, capacity, protocols, and overall activity. Resource requirements to consider

for PVS deployments include raw network speed, the size of the network being monitored, and the configuration of the

PVS application.

The following chart outlines some basic hardware requirements for operating PVS:

Scenario

Minimum Recommended Hardware

Passive Vulnerability Scanner managing up to

50,000 hosts *

CPU: 1 dual-core 2 GHz CPU

Memory: 2 GB RAM (4 GB RAM recommended)

Passive Vulnerability Scanner managing in

excess of 50,000 hosts

CPU: 1 dual-core 3 GHz CPU (2 dual-core recommended)

Memory: 4 GB RAM (8 GB RAM recommended)

* Note: The ability to monitor a given number of hosts rests heavily on the bandwidth, memory, and processor

power available to the system running PVS.

Please research your VM software vendor for comparative recommendations as VMs typically see up to a

30% loss in efficiency compared with dedicated servers.

Processor requirements will increase with greater throughput and number of network interfaces. Memory requirements will

increase for networks with more hosts. The requirements for both of these components are affected by options such as a

long report-lifetime and enabling some or all of the PVS optional services in the configuration file.

Disk space requirements for PVS will vary depending on usage based on the amount and length of time data is stored on

the system.

Software and Licensing

Download or Obtain the Software

To install the PVS, obtain the correct version for your desired operating system from the “Downloads” section of the

Tenable Support Portal. Confirm the integrity of the installation package by comparing the download MD5 checksum with

the one listed in the product release notes.

It is important to ensure that the correct build for your operating environment is downloaded to ensure binary

compatibility.

PVS Subscription

A PVS subscription Activation Code is available to enable PVS to operate in a stand-alone mode. This mode enables the

PVS results to be viewed from a HTML interface enabled on the PVS server.

SecurityCenter Continuous View

Continuous View includes PVS as part of a bundled license package with SecurityCenter. This license allows an unlimited

number of PVS deployments to monitor an unlimited number of networks. SecurityCenter’s IP view will be constrained by

the license purchased with it.
