DoS	Denial of Service. Interruptions to internet service caused by a DoS attack.
DoS attack	An attack against a Web site, a network, a system, or other service provider intended to disrupt
	its ability to provide services to its users. Software that performs a DoS attack (DoS software )
	overloads the service provider with requests for service until its capacity to respond to new service
	requests is exceeded. Legitimate requests for service cannot access to the service until the attack
	is stopped. See also Distributed DoS attack.
DoS software	Denial of Service software used by attackers to control and initiate DoS attacks against other
	systems and networks, either within your administrative domain, outside it, or over the Internet.
	Also called Intrusion software.
Egress filtering	Filtering software that prevents IP packets with randomly generated source addresses from exiting
	your system or network, when one of your systems has been compromised and when the system
	is being used to perpetrate an attack against other systems. See also Ingress filtering.
File Transfer	See FTP.
Protocol
Firewall	Hardware and software that lies between two networks, such as an internal network and an
	Internet service provider. The firewall protects your network by blocking unwanted users from

FTP	File Transfer Protocol. A client/server protocol that lets a user on one computer transfer files to
	and from another computer over a TCP/IP network.

IMAP	Internet Message Access Protocol. A method of accessing e-mail or bulletin board messages kept
	on a (possibly shared) mail server. IMAP permits an e-mail client program to access remote
	messages as if they were local.
Ingress filtering	Filtering software that removes IP packets with untrusted source addresses before they have a
	chance to enter and affect your system or network. See also Egress filtering.
Intrusion software	See DoS software.
LDAP	Lightweight Directory Access Protocol. An Internet standard protocol that runs over TCP/IP and
	can be used to provide a standalone directory service or to provide lightweight access to the
	X.500 directory.
LDAP entry	A collection of attribute and value pairs stored on an LDAP server that describe something of
	interest; for example, a person, a company, or a printer. LDAP entries can be organized as a
	hierarchical tree of objects. The full set of attributes for an entry in the tree is defined through
	object-oriented inheritance of attributes from parent entries.

	cursor-addressable, character-cell terminals or terminal emulators on UNIX or OpenVMS systems.
Mail Exchange	See MX record.
