| 419 Scam: This is the generic name for what is known as
Nigerian email Scam. This

or other entity, or the integrity of data stored, transmitted, or
otherwise exposed to unauthorized modification in an information
system, or to establish the validity of a transmission. |
| Authentication: Security measure designed to establish the
validity of a transmission, message, or originator, or a means of
verifying an individual’s authorization to receive specific

| Denial of Service (DoS): A means of attack against a computer,

of successively trying all the words in some large, exhaustive list

programs receive instruction from a controller program in order to
carry out an attack - the attack itself is designed to disable or
shutdown the target of the attack. |
| DNS: Domain Name System. The primary purpose
of the DNS is to allow us to locate a web site by using its domain
name rather than its IP address. For example, when you
type in "http://www.mailfrontier.com," the computer doesn't
immediately know that it should look for MailFrontier's Web site.
Instead, it sends a request to the nearest DNS server, which finds
the correct IP address. |
| DNS Spoofing: Assuming the DNS name of another system by
either corrupting the name service cache of a victim system, or by
compromising a domain name server for a valid domain. |
| Emoticon: These are the little text-based faces and

| Firewall: A computer firewall is used to protect a
networked server or client machine from damage by unauthorized users.

designed to perform some unauthorized (and often harmful or undesirable)
act such as viruses, worms, and trojans. |
| MIME: Multipurpose Internet Mail Extensions. The standard
for defining the types of files attached to standard Internet mail
messages. The MIME standard is also used in many situations where
one computer program needs to communicate with another program about
what kind of file is being sent. |
| Phishing: From a business point-of-view the term has its
roots in the fact that Internet scammers use lures to "fish" for
users' computer related information (account names, passwords, etc)
in an attempt to gain access to a company’s information systems. |
| Port: An internet port is a number that indicates what kind
of protocol a server on the Internet is using. For example, Web servers
typically are listed on port 80. Web browsers use this port by default
when accessing Web pages. FTP uses port 21, e-mail uses port 25,
etc. |
| Probe: An attempt to gather information about an information
system for the apparent purpose of circumventing its security controls. |
| Proxy: Software agent that performs a function or operation

adversely impact an information system through unauthorized access,
destruction, disclosure, modification of data, and/or denial of service. |
| Trojan Horse: A program that either pretends to have, or

actually contains a damaging payload. Most frequently, the usage
is shortened to "Trojan". Trojan Horses are not technically
viruses, since they do not replicate |
| Virus: Self-replicating, malicious code that attaches itself
to an application program or other executable system component and
leaves no obvious signs of its presence. |
| Vulnerability: Weakness in an information system, system
security procedures, internal controls, or implementation that could
be exploited. |
| Worm: Independent program that replicates from machine to
