Attacks
CAM tables are often the target of layer 2 network attacks in a local area network to set up man-in-the-middle attacks. A threat agent which has control of a device connected to an Ethernet switch can attack the switch's CAM table. This attack usually involves exploiting a vulnerability in switch design that appears when the switch runs out of space to record all of the MAC address to port mappings it learns. If the table fills up due to MAC flooding, most switches are no longer able to reliably add new MAC addresses.

Famous quotes containing the word attacks:
“Neither the wrath of Heaven nor the attacks of enemies
are as fatal as Pleasure alone when she infects the mind.”
—Silius Italicus (26–101)
“I must ... warn my readers that my attacks are directed against themselves, not against my stage figures.”
—George Bernard Shaw (1856–1950)
“There exists, at the bottom of all abasement and misfortune, a last extreme which rebels and joins battle with the forces of law and respectability in a desperate struggle, waged partly by cunning and partly by violence, at once sick and ferocious, in which it attacks the prevailing social order with the pin-pricks of vice and the hammer-blows of crime.”
—Victor Hugo (1802–1885)
