POLICY TYPE DESCRIPTION
P2P Peer-to-peer (P2P) is where computing devices link directly to each
other and can directly initiate communication with each other; they
do not need an intermediary. A device can be both the client and the
server. In the ZyWALL, P2P refers to peer-to-peer applications such
as e-Mule, e-Donkey, BitTorrent, iMesh, etc.
IM IM (Instant Messenger) refers to chat applications. Chat is real-time,
text-based communication between two or more users via networks-
connected computers. After you enter a chat (or chat room), any
room member can type a message that will appear on the monitors of
all the other participants.
SPAM Spam is unsolicited “junk” e-mail sent to large numbers of people to
promote products or services.
DoS/DDoS The goal of Denial of Service (DoS) attacks is not to steal
information, but to disable a device or network on the Internet.
A Distributed Denial of Service (DDoS) attack is one in which multiple
compromised systems attack a single target, thereby causing denial
of service for users of the targeted system.
