Q101. Users can authenticate to a company’s web applications using their credentials from a popular social media site. Which of the following poses the greatest risk with this integration?
A. Malicious users can exploit local corporate credentials with their social media credentials
B. Changes to passwords on the social media site can be delayed from replicating to the company
C. Data loss from the corporate servers can create legal liabilities with the social media site
D. Password breaches to the social media site affect the company application as well
Answer: D
Explanation:
Social networking and having you company’s application authentication ‘linked’ to users’ credential that they use on social media sites exposes your company’s application exponentially more than is necessary. You should strive to practice risk avoidance.
Q102. A company’s chief information officer (CIO) has analyzed the financial loss associated with the company’s database breach. They calculated that one single breach could cost the company $1,000,000 at a minimum. Which of the following documents is the CIO MOST likely updating?
A. Succession plan
B. Continuity of operation plan
C. Disaster recovery plan
D. Business impact analysis
Answer: D
Explanation:
Business impact analysis (BIA) is the process of evaluating all of the critical systems in an organization to define impact and recovery plans. BIA isn’t concerned with external threats or vulnerabilities; the analysis focuses on the impact a loss would have on the organization. A BIA comprises the following: identifying critical functions, prioritizing critical business functions, calculating a timeframe for critical systems loss, and estimating the tangible impact on the organization.
Q103. Joe, the system administrator, is performing an overnight system refresh of hundreds of user computers. The refresh has a strict timeframe and must have zero downtime during business hours. Which of the following should Joe take into consideration?
A. A disk-based image of every computer as they are being replaced.
B. A plan that skips every other replaced computer to limit the area of affected users.
C. An offsite contingency server farm that can act as a warm site should any issues appear.
D. A back-out strategy planned out anticipating any unforeseen problems that may arise.
Answer: D
Explanation:
A backout is a reversion from a change that had negative consequences. It could be, for example, that everything was working fine until you installed a service pack on a production machine, and then services that were normally available were no longer accessible. The backout, in this instance, would revert the system to the state that it was in before the service pack was applied. Backout plans can include uninstalling service packs, hotfixes, and patches, but they can also include reversing a migration and using previous firmware. A key component to creating such a plan is identifying what events will trigger your implementing the backout.
Q104. Which of the following tools would a security administrator use in order to identify all running services throughout an organization?
A. Architectural review
B. Penetration test
C. Port scanner
D. Design review
Answer: C
Explanation:
Different services use different ports. When a service is enabled on a computer, a network port is opened for that service. For example, enabling the HTTP service on a web server will open port 80 on the server. By determining which ports are open on a remote server, we can determine which services are running on that server. A port scanner is a software application designed to probe a server or host for open ports. This is often used by administrators to verify security policies of their networks and by attackers to identify running services on a host with the view to compromise it. A port scan or portscan can be defined as a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port. While not a nefarious process in and of itself, it is one used by hackers to probe target machine services with the aim of exploiting a known vulnerability of that service. However the majority of uses of a port scan are not attacks and are simple probes to determine services available on a remote machine.
Q105. Which of the following wireless protocols could be vulnerable to a brute-force password attack? (Select TWO).
A. WPA2-PSK
B. WPA - EAP - TLS
C. WPA2-CCMP
D. WPA -CCMP
E. WPA - LEAP
F. WEP
Answer: A,E
Explanation:
A brute force attack is an attack that attempts to guess a password. WPA2-PSK and WEP both use a “Pre-Shared Key”. The pre-shared key is a password and therefore is susceptible to a brute force attack.
Q106. Users report that they are unable to access network printing services. The security technician checks the router access list and sees that web, email, and secure shell are allowed. Which of the following is blocking network printing?
A. Port security
B. Flood guards
C. Loop protection
D. Implicit deny
Answer: D
Explanation:
Implicit deny says that if you aren’t explicitly granted access or privileges for a resource, you’re denied access by default. The scenario does not state that network printing is allowed in the router access list, therefore, it must be denied by default.
Q107. A hacker has discovered a simple way to disrupt business for the day in a small company which relies on staff working remotely. In a matter of minutes the hacker was able to deny remotely working staff access to company systems with a script. Which of the following security controls is the hacker exploiting?
A. DoS
B. Account lockout
C. Password recovery
D. Password complexity
Answer: B
Explanation:
B: Account lockout automatically disables an account due to repeated failed log on attempts. The hacker must have executed a script to repeatedly try logging on to the remote accounts, forcing the account lockout policy to activate.
Q108. The process of making certain that an entity (operating system, application, etc.) is as secure as it can be is known as:
A. Stabilizing
B. Reinforcing
C. Hardening
D. Toughening
Answer: C
Explanation:
Hardening is the process of securing a system by reducing its surface of vulnerability. Reducing the surface of vulnerability typically includes removing unnecessary functions and features, removing unnecessary usernames or logins and disabling unnecessary services.
Q109. After Ann, a user, logs into her banking websites she has access to her financial institution mortgage, credit card, and brokerage websites as well. Which of the following is being described?
A. Trusted OS
B. Mandatory access control
C. Separation of duties
D. Single sign-on
Answer: D
Explanation:
Single sign-on means that once a user (or other subject) is authenticated into a realm, re-authentication is not required for access to resources on any realm entity. The question states that when Ann logs into her banking websites she has access to her financial institution mortgage, credit card, and brokerage websites as well. This describes an SSO scenario.
Q110. Employee badges are encoded with a private encryption key and specific personal information.
The encoding is then used to provide access to the network. Which of the following describes this access control type?
A. Smartcard
B. Token
C. Discretionary access control
D. Mandatory access control
Answer: A
Explanation:
Smart cards are credit-card-sized IDs, badges, or security passes with an embedded integrated circuit chip that can include data regarding the authorized bearer. This data can then be used for identification and/or authentication purposes.
