mechanisms that delay or limit the availability of that
system or service. Due to this, systems or services are
,rendered inaccessible to their intended users, Trojans,
phishing, and cross-site scripting attacks try to gain access
o the system or data, and therefore do not primarily aim at
compromising the system's availability.
