Description

Network File System (NFS) is a convenient way to share files over a network providing centralized management. However, NFS can be difficult to secure and is most viable within trusted networks. This Lab illustrates how easy it can be for an attacker to discover and exploit an insecure NFS file share. 

You will use Kali Linux as the platform for launching the attack. Kali Linux includes a variety of security analysis tools by default. The target is a Metasploitable 2 Linux host. Both hosts are running as virtual machines in a Hyper-V virtual environment.

This Lab is designed for the CREST Practitioner Security Analyst (CPSA) certification examination but is of value to security practitioners in general.

Learning Objectives

Upon completion of this Lab you will be able to:

  • Scan remote systems for NFS access using Nmap
  • Mount NFS shares on Linux
  • Learn about the kinds of sensitive information attackers may target
  • Describe the options available for securing NFS shares when they must be used

Intended Audience

This Lab is intended for:

  • CREST CPSA certification examinees
  • Security practitioners
  • System administrators

Prerequisites

You should be familiar with:

  • Working at the command-line in Linux

You can fulfill the prerequisites by completing the Linux Command Line Byte Session Learning Path.
