A profile consists of three separate screens. If you want to configure just
one screen for an IDP profile, click OK to save your settings to the NXC,
complete the profile and return to the profile summary page.
Click Cancel to return to the profile summary page without saving any
changes.
If you want to configure more than one screen for an IDP profile, click
Save to save the configuration to the NXC, but remain in the same page.
You may then go to another profile screen (tab) in order to complete the
profile. Click OK in the final profile screen to complete the profile.
DESCRIPTION
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 NXC, P2P refers to peer-to-peer applications such as e-
Mule, e-Donkey, BitTorrent, iMesh, etc.
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 is unsolicited "junk" e-mail sent to large numbers of people to
promote products or services.
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.
