NO.1 Jane, an individual, has recently been calling various financial offices pretending to be another
person to gain financial information. Which of the following attacks is being described?
A. Phishing
B. Tailgating
C. Pharming
D. Vishing
Answer: D

JK0-022 Study Guide Exam Prep
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.

NO.2 Two programmers write a new secure application for the human resources department to
store personal identifiable information. The programmers make the application available to
themselves using an uncommon port along with an ID and password only they know. This is an
example of which of the following?
A. Spyware
B. Backdoor
C. Root Kit
D. Logic Bomb
Answer: B

JK0-022 Study Guide test questions
Explanation:
A backdoor in a computer system (or cryptosystem or algorithm) is a method of bypassing normal
authentication, securing unauthorized remote access to a computer, obtaining access to plaintext,
and so on, while attempting to remain undetected. The backdoor may take the form of an installed
program (e.g., Back Orifice) or may subvert the system through a rootkit. A backdoor in a login
system might take the form of a hard coded user and password combination which gives access to
the system. Although the number of backdoors in systems using proprietary software (software
whose source code is not publicly available) is not widely credited, they are nevertheless frequently
exposed. Programmers have even succeeded in secretly installing large amounts of benign code as
Easter eggs in programs, although such cases may involve official forbearance, if not actual
permission. Many computer worms, such as Sobig and Mydoom, install a backdoor on the affected
computer (generally a PC on broadband running Microsoft Windows and Microsoft Outlook). Such
backdoors appear to be installed so that spammers can send junk e-mail from the infected machines.
Others, such as the Sony/BMG rootkit distributed silently on millions of music CDs through late 2005,
are intended as DRM measures-and, in that case, as data gathering agents, since both surreptitious
programs they installed routinely contacted central servers.

NO.3 Which of the following security architecture elements also has sniffer functionality? (Select
TWO).
A. WAP
B. SSL accelerator
C. IPS
D. IDS
E. HSM
Answer: C,D

JK0-022 Study Guide dumps torrent
Explanation:
Sniffer functionality means the ability to capture and analyze the content of data packets as they
are transmitted across the network.
IDS and IPS systems perform their functions by capturing and analyzing the content of data
packets.
An intrusion detection system (IDS) is a device or software application that monitors network or
system activities for malicious activities or policy violations and produces reports to a management
station. IDS come in a variety of "flavors" and approach the goal of detecting suspicious traffic in
different ways. There are network based (NIDS) and host based (HIDS) intrusion detection
systems. Some systems may attempt to stop an intrusion attempt but this is neither required nor
expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily
focused on identifying possible incidents, logging information about them, and reporting attempts.
In addition, organizations use IDPSes for other purposes, such as identifying problems with
security policies, documenting existing threats and deterring individuals from violating security
policies. IDPSes have become a necessary addition to the security infrastructure of nearly every
organization.
IDPSes typically record information related to observed events, notify security administrators of
important observed events and produce reports. Many IDPSes can also respond to a detected
threat by attempting to prevent it from succeeding. They use several response techniques, which
involve the IDPS stopping the attack itself, changing the security environment (e.g. reconfiguring a
firewall) or changing the attack's content.

NO.4 During a disaster recovery planning session, a security administrator has been tasked with
determining which threats and vulnerabilities pose a risk to the organization. Which of the following
should the administrator rate as having the HIGHEST frequency of risk to the organization?
A. Large scale natural disasters
B. Hostile takeovers
C. Corporate espionage
D. Malware and viruses
Answer: D

NO.5 Which of the following is a penetration testing method?
A. Running a port scanner against the target's network
B. Calling the target's helpdesk, requesting a password reset
C. Searching the WHOIS database for administrator contact information
D. War driving from a target's parking lot to footprint the wireless network
Answer: B

NO.6 Human Resources suspect an employee is accessing the employee salary database. The
administrator is asked to find out who it is. In order to complete this task, which of the following is a
security control that should be in place?
A. Account lockout should be enabled
B. Shared accounts should be prohibited.
C. Time of day restrictions should be in use
D. Privileges should be assigned to groups rather than individuals
Answer: B

JK0-022 Study Guide Exam Cram
Explanation:
Since distinguishing between the actions of one person and another isn't possible if they both use a
shared account, shared accounts should not be allowed. If shared accounts are being used, the
administrator will find the account, but have more than one suspect. To nullify this occurrence,
Shared accounts should be prohibited.

NO.7 Users have been reporting that their wireless access point is not functioning. They state that it
allows slow connections to the internet, but does not provide access to the internal network. The
user provides the SSID and the technician logs into the company's access point and finds no issues.
Which of the following should the technician do?
A. Change the access point from WPA2 to WEP to determine if the encryption is too strong
B. Reconfigure the access point so that it is blocking all inbound and outbound traffic as a
troubleshooting gap
C. Clear all access logs from the AP to provide an up-to-date access list of connected users
D. Check the MAC address of the AP to which the users are connecting to determine if it is an
imposter
Answer: D

JK0-022 Study Guide certification
Explanation:
The users may be connecting to a rogue access point. The rogue access point could be hosting a
wireless network that has the same SSID as the corporate wireless network. The only way to tell for
sure if the access point the users are connecting to is the correct one is to check the MAC address.
Every network card has a unique 48-bit address assigned. A media access control address (MAC
address) is a unique identifier assigned to network interfaces for communications on the physical
network segment. MAC addresses are used as a network address for most IEEE 802 network
technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access
control protocol sublayer of the OSI reference model. MAC addresses are most often assigned by the
manufacturer of a network interface controller (NIC) and are stored in its hardware, such as the
card's read-only memory or some other firmware mechanism. If assigned by the manufacturer, a
MAC address usually encodes the manufacturer's registered identification number and may be
referred to as the burned-in address (BIA). It may also be known as an Ethernet hardware address
(EHA), hardware address or physical address. This can be contrasted to a programmed address,
where the host device issues commands to the NIC to use an arbitrary address. A network node may
have multiple NICs and each NIC must have a unique MAC address. MAC addresses are formed
according to the rules of one of three numbering name spaces managed by the Institute of Electrical
and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64.

NO.8 The main corporate website has a service level agreement that requires availability 100% of the
time, even in the case of a disaster. Which of the following would be required to meet this demand?
A. Geographically disparate site redundant datacenter
B. Cold site implementation for the datacenter
C. Localized clustering of the datacenter
D. Warm site implementation for the datacenter
Answer: A

JK0-022 Study Guide dumps JK0-022 Study Guide study guide
Explanation:
Data backups, redundant systems, and disaster recovery plans all support availability. AN in this case
a geographically disparate site redundant datacenter represents 100% availability regardless of
whether a disaster event occurs.
