JK0-022기출문제 JK0-022시험
Explanation:
Vishing
(voice or VoIP phishing) is an electronic fraud tactic in which individuals are
tricked into
revealing critical financial or personal information to
unauthorized entities. Vishing works like
phishing but does not always occur
over the Internet and is carried out using voice technology. A
vishing attack
can be conducted by voice email, VoIP (voice over IP), or landline or cellular
telephone.
The potential victim receives a message, often generated by speech
synthesis, indicating that
suspicious activity has taken place in a credit
card account, bank account, mortgage account or other
financial service in
their name. The victim is told to call a specific telephone number and
provide
information to "verify identity" or to "ensure that fraud does not
occur." If the attack is carried out by
telephone, caller ID spoofing can
cause the victim's set to indicate a legitimate source, such as a bank
or a
government agency.
Vishing is difficult for authorities to trace,
particularly when conducted using VoIP. Furthermore, like
many legitimate
customer services, vishing scams are often outsourced to other countries,
which
may render sovereign law enforcement powerless.
Consumers can
protect themselves by suspecting any unsolicited message that suggests they
are
targets of illegal activity, no matter what the medium or apparent
source. Rather than calling a
number given in any unsolicited message, a
consumer should directly call the institution named,
using a number that is
known to be valid, to verify all recent activity and to ensure that the
account
information has not been tampered with.

Warm site implementation for the datacenter
C. Cold site implementation for

D. Geographically disparate site redundant
datacenter
