Intrusion: examples: trojans
 “a Trojan horse is a malicious
program that is disguised as or
embedded within legitimate software.
The term is derived from the classical
myth of the Trojan Horse. They may
look useful or interesting (or at the
very least harmless) to an
unsuspecting user, but are actually
harmful when executed.”

Intrusion: examples: spyware
 “…applications [that] collect information,
may or may not install in stealth, and
are designed to transmit that
information to 2nd, or 3rd parties
covertly employing the user's connection
without their consent and knowledge.
The word defines the actual intent; this
is software (ware) that is designed to
collect information in secret (spy).”
