A credit card is a memory card that functions a type of two-factor authentication. The card is something you have, and its PIN is something you know. Multifactor authentication requires a user to provide two or more different types of authentication factors to prove their identity.
Q672. A company hired Joe, an accountant. The IT administrator will need to create a new account for
Joe. The company uses groups for ease of management and administration of user accounts.
Joe will need network access to all directories, folders and files within the accounting department.
Which of the following configurations will meet the requirements?
A. Create a user account and assign the user account to the accounting group.
B. Create an account with role-based access control for accounting.
C. Create a user account with password reset and notify Joe of the account creation.
D. Create two accounts: a user account and an account with full network administration rights.
Answer: B
Explanation:
Role-based Access Control is basically based on a user’s job description. When a user is assigned a specific role in an environment, that user’s access to objects is granted based on the required tasks of that role. The IT administrator should, therefore, create an account with role-based access control for accounting for Joe.
Q673. After a recent internal audit, the security administrator was tasked to ensure that all credentials must be changed within 90 days, cannot be repeated, and cannot contain any dictionary words or patterns. All credentials will remain enabled regardless of the number of attempts made. Which of the following types of user account options were enforced? (Select TWO).
A. Recovery
B. User assigned privileges
C. Lockout
D. Disablement
E. Group based privileges
F. Password expiration
G. Password complexity
Answer: F,G
Explanation:
Password complexity often requires the use of a minimum of three out of four standard character types for a password. The more characters in a password that includes some character type complexity, the more resistant it is to password-cracking techniques. In most cases, passwords are set to expire every 90 days.
Q674. A company needs to receive data that contains personally identifiable information. The company requires both the transmission and data at rest to be encrypted. Which of the following achieves this goal? (Select TWO).
A. SSH
B. TFTP
C. NTLM
D. TKIP
E. SMTP
F. PGP/GPG
Answer: A,F
Explanation:
We can use SSH to encrypt the transmission and PGP/GPG to encrypt the data at rest (on disk).
A: Secure Shell (SSH) is a cryptographic protocol that can be used to secure network communication. It establishes a secure tunnel over an insecure network.
F: Pretty Good Privacy (PGP) is a data encryption and decryption solution that can be used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications.
Q675. What is a system that is intended or designed to be broken into by an attacker?
A. Honeypot
B. Honeybucket
C. Decoy
D. Spoofing system
Answer: A
Explanation:
A honeypot is a system whose purpose it is to be attacked. An administrator can watch and study
the attack to research current attack methodologies.
According to the Wepopedia.com, a Honeypot luring a hacker into a system has several main
purposes:
The administrator can watch the hacker exploit the vulnerabilities of the system, thereby learning
where the system has weaknesses that need to be redesigned.
The hacker can be caught and stopped while trying to obtain root access to the system.
By studying the activities of hackers, designers can better create more secure systems that are
potentially invulnerable to future hackers.
There are two main types of honeypots:
Production - A production honeypot is one used within an organization's environment to help
mitigate risk.
Research – A research honeypot add value to research in computer security by providing a
platform to study the threat.

Q676. An administrator finds that non-production servers are being frequently compromised, production servers are rebooting at unplanned times and kernel versions are several releases behind the version with all current security fixes.
Which of the following should the administrator implement?
A. Snapshots
B. Sandboxing
C. Patch management
D. Intrusion detection system
Answer: C
Explanation:
Patch management is the process of maintaining the latest source code for applications and operating systems by applying the latest vendor updates. This helps protect a systems from newly discovered attacks and vulnerabilities.
Q677. The incident response team has received the following email message.
From: monitor@ext-company.com To: security@company.com Subject: Copyright infringement
A copyright infringement alert was triggered by IP address 13.10.66.5 at 09: 50: 01 GMT.
After reviewing the following web logs for IP 13.10.66.5, the team is unable to correlate and identify the incident.
09:
45: 33 13.10.66.5 http: //remote.site.com/login.asp?user=john
09:
50: 22 13.10.66.5 http: //remote.site.com/logout.asp?user=anne
10: 50: 01 13.10.66.5 http: //remote.site.com/access.asp?file=movie.mov
11: 02: 45 13.10.65.5 http: //remote.site.com/download.asp?movie.mov=ok
Which of the following is the MOST likely reason why the incident response team is unable to identify and correlate the incident?
A. The logs are corrupt and no longer forensically sound.
B. Traffic logs for the incident are unavailable.
C. Chain of custody was not properly maintained.
D. Incident time offsets were not accounted for.
Answer: D
Explanation:
It is quite common for workstation times to be off slightly from actual time, and that can happen with servers as well. Since a forensic investigation is usually dependent on a step-by-step account of what has happened, being able to follow events in the correct time sequence is critical. Because of this, it is imperative to record the time offset on each affected machine during the investigation. One method of assisting with this is to add an entry to a log file and note the time that this was done and the time associated with it on the system.
Q678. Which of the following devices is used for the transparent security inspection of network traffic by redirecting user packets prior to sending the packets to the intended destination?
A. Proxies
B. Load balancers
C. Protocol analyzer
D. VPN concentrator
Answer: A
Explanation:
Q679. After a recent breach, the security administrator performs a wireless survey of the corporate network. The security administrator notices a problem with the following output:
MAC SSID ENCRYPTION POWER BEACONS
00:10:A1:36:12:CC MYCORP WPA2 CCMP 60 1202
00:10:A1:49:FC:37 MYCORP WPA2 CCMP 70 9102
FB:90:11:42:FA:99 MYCORP WPA2 CCMP 40 3031
00:10:A1:AA:BB:CC MYCORP WPA2 CCMP 55 2021 00:10:A1:FA:B1:07 MYCORP WPA2 CCMP 30 6044
Given that the corporate wireless network has been standardized, which of the following attacks is underway?
A. Evil twin
B. IV attack
C. Rogue AP
D. DDoS
Answer: A
Explanation:
The question states that the corporate wireless network has been standardized. By ‘standardized’ it means the wireless network access points are running on hardware from the same vendor. We can see this from the MAC addresses used. The first half of a MAC address is vendor specific. The second half is network adapter specific. We have four devices with MAC addresses that start with 00:10:A1. The “odd one out” is the device with a MAC address starting FB:90:11. This device is from a different vendor. The SSID of the wireless network on this access point is the same as the other legitimate access points. Therefore, the access point with a MAC address starting FB:90:11 is impersonating the corporate access points. This is known as an Evil Twin.
An evil twin, in the context of network security, is a rogue or fake wireless access point (WAP) that appears as a genuine hotspot offered by a legitimate provider. In an evil twin attack, an eavesdropper or hacker fraudulently creates this rogue hotspot to collect the personal data of unsuspecting users. Sensitive data can be stolen by spying on a connection or using a phishing technique. For example, a hacker using an evil twin exploit may be positioned near an authentic Wi-Fi access point and discover the service set identifier (SSID) and frequency. The hacker may then send a radio signal using the exact same frequency and SSID. To end users, the rogue evil twin appears as their legitimate hotspot with the same name. In wireless transmissions, evil twins are not a new phenomenon. Historically, they were known as honeypots or base station clones. With the advancement of wireless technology and the use of wireless devices in public areas, it is very easy for novice users to set up evil twin exploits.
Q680. After a security incident involving a physical asset, which of the following should be done at the beginning?
A. Record every person who was in possession of assets, continuing post-incident.
B. Create working images of data in the following order: hard drive then RAM.
C. Back up storage devices so work can be performed on the devices immediately.
D. Write a report detailing the incident and mitigation suggestions.
Answer: A
Explanation:
Asset tracking is the process of maintaining oversight over inventory, and ensuring that a device is still in the possession of the assigned authorized user.
