Pivoting

Once you have obtained a foothold by compromising a system and ensuring that you will have continued access, you can leverage that system to obtain a new perspective on the target network or systems. Using a compromised system can provide a new path into a network or help you identify new targets that were not visible from the original scan viewpoint.

Figure 6.14 shows an attacker pivoting once they have breached a vulnerable system inside an Internet-accessible DMZ. The attacker may have discovered a vulnerable web service or another front-facing, exploitable vulnerability. Once they have compromised a server in the DMZ, they can scan systems that were not previously visible through the multiple layers of firewalls that the example organization has put into place. Note that in this case, both additional DMZ servers and workstations in the internal work are accessible. The same techniques discussed in prior chapters of this book would then be leveraged to conduct information...
