Quick Answer
The answer is token impersonation, a technique used to assume another user's security context, and the tool commonly employed to exploit it is Incognito. This method works by allowing a process to steal or duplicate an access token—a Windows object that contains the security identity and privileges of a logged-in user—enabling an attacker to act as that user, often escalating from a low-privileged account to SYSTEM or administrator. On the Certified Ethical Hacker CEH exam, this concept tests your understanding of Windows privilege escalation vectors, frequently appearing in questions about post-exploitation or lateral movement, with a common trap being confusion between token impersonation and token theft (the latter requires SeImpersonatePrivilege). A helpful memory tip: think of Incognito as a digital mask—once you put it on, you’re no longer yourself, but whoever’s token you stole.

Correct answer & explanation
✓
A technique to assume another user's security context; Incognito
Token impersonation allows a process to assume the security context of another user. Tools like `incognito` can list available tokens and impersonate them, often to gain administrator privileges.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related CEH questions on access control and AAA configuration.
