Tailgating
| “ | involves connecting a computer user to a computer in the same session as and under the same identifier as another computer user whose session has been interrupted. This situation happens when a dial-up or direct connect session is abruptly terminated, and a communications controller (concentrator or packet assembler/disassembler) incorrectly allows a second user to be patched directly into the first user's still-open files.[1] | ” |
