Which is Better: VLAN Hopping or Session Hijacking?

Which of the following BEST describes the differences between VLAN hopping and session hijacking?

A.

VLAN hopping involves the unauthorized transition from one VLAN to another to gain additional access.

Session hijacking involves overriding a user's web connection to execute commands

B.

VLAN hopping is a brute force attack executed to gain additional access.

Session hijacking involves physically disrupting a network connection

C.

VLAN hopping involves overriding a user network connection to execute malicious commands.

Session hijacking involves compromising a host to elevate privileges

D.

VLAN hopping is the act of exploiting poor VLAN tagging.

Session hijacking is a web-based attack aimed at privilege escalation.

A.

The BEST description of the differences between VLAN hopping and session hijacking is option A: VLAN hopping involves the unauthorized transition from one VLAN to another to gain additional access, while session hijacking involves overriding a user's web connection to execute commands.

VLAN hopping is a security exploit where an attacker gains unauthorized access to a VLAN by taking advantage of misconfigured network switch settings. By exploiting these vulnerabilities, an attacker can gain access to other VLANs on the network, which may contain sensitive data or resources. VLAN hopping can occur through two methods: Double Tagging and Switch Spoofing.

In Double Tagging, an attacker sends a packet with two VLAN tags (one for the attacker's VLAN and one for the target VLAN) to a switch. The switch, not recognizing the second tag, forwards the packet to the target VLAN. In Switch Spoofing, an attacker spoofs a switch by sending a message to the target VLAN's switch and pretending to be a legitimate switch. The attacker can then redirect traffic to their own VLAN.

On the other hand, session hijacking involves an attacker taking control of an ongoing session between two systems. By doing so, the attacker can bypass authentication mechanisms and gain unauthorized access to a system. Session hijacking can occur through various methods, such as cookie theft, session fixation, and man-in-the-middle attacks.

In cookie theft, an attacker steals a user's session cookie and uses it to impersonate the user. In session fixation, an attacker sets the session ID of the user before the user logs in, allowing the attacker to use the same session ID to hijack the session later. In man-in-the-middle attacks, an attacker intercepts and alters communications between two systems, allowing the attacker to gain access to the session.

In summary, VLAN hopping involves gaining unauthorized access to other VLANs on the network, while session hijacking involves taking control of an ongoing session to gain unauthorized access to a system.
