Which technique would be used to masquerade as a trusted host to gain unauthorized access to a network?

• A. IP Address Decoy
• B. Randomizing Host Order
• C. Creating Custom Packets
• D. IP Address Spoofing

Answer: (D)

Masquerading as a trusted host hinges on making traffic look like it comes from a legitimate machine. The technique that achieves this is IP address spoofing, where the attacker forges the source IP in packets to appear as if they’re from a trusted host. By presenting a trusted address, the attacker can bypass simple IP-based access controls, trigger responses intended for that host, or facilitate further steps like session hijacking, increasing the chances of unauthorized access. Keep in mind that spoofing alone isn’t a guaranteed entry point; it usually relies on weaknesses in the network’s authentication or filtering, which is why it’s often combined with other techniques in real attacks. Other options don’t fit as well. An IP address decoy isn’t a recognized method for impersonating a host to gain access. Randomizing host order doesn’t involve impersonating a trusted identity, and creating custom packets describes crafting traffic for various purposes but doesn’t inherently masquerade as a legitimate host.
