Denial of Service
Also known as “cyber attacks” or “nukes,” Denial of Service
attacks are deliberate attempts by hackers to bring your network
down.
Attacks include
• System floods, which overwhelm a network with more
requests than it can handle
• Attempts to cause a particular individual’s computer to crash
• Attempts to disrupt service to a specific system or person

to the Internet and prevent the AP+4 from
accepting any new requests to connect.
