Q651. A recent audit has revealed weaknesses in the process of deploying new servers and network devices. Which of the following practices could be used to increase the security posture during deployment? (Select TWO).
A. Deploy a honeypot
B. Disable unnecessary services
C. Change default passwords
D. Implement an application firewall
E. Penetration testing
Q652. Ann, the network administrator, has learned from the helpdesk that employees are accessing the wireless network without entering their domain credentials upon connection. Once the connection is made, they cannot reach any internal resources, while wired network connections operate smoothly. Which of the following is MOST likely occurring?
A. A user has plugged in a personal access point at their desk to connect to the network wirelessly.
B. The company is currently experiencing an attack on their internal DNS servers.
C. The companyâs WEP encryption has been compromised and WPA2 needs to be implemented instead.
D. An attacker has installed an access point nearby in an attempt to capture company information.
The question implies that users should be required to enter their domain credentials upon connection to the wireless network. The fact that they are connecting to a wireless network without being prompted for their domain credentials and they are unable to access network resources suggests they are connecting to a rogue wireless network. A rogue access point is a wireless access point that has either been installed on a secure company network without explicit authorization from a local network administrator, or has been created to allow a hacker to conduct a man-in-the-middle attack. Rogue access points of the first kind can pose a security threat to large organizations with many employees, because anyone with access to the premises can install (maliciously or non-maliciously) an inexpensive wireless router that can potentially allow access to a secure network to unauthorized parties. Rogue access points of the second kind target networks that do not employ mutual authentication (client-server server-client) and may be used in conjunction with a rogue RADIUS server, depending on security configuration of the target network. To prevent the installation of rogue access points, organizations can install wireless intrusion prevention systems to monitor the radio spectrum for unauthorized access points.
Q653. A company wants to ensure that all credentials for various systems are saved within a central database so that users only have to login once for access to all systems. Which of the following would accomplish this?
A. Multi-factor authentication
B. Smart card access
C. Same Sign-On
D. Single Sign-On
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. Single sign-on is able to internally translate and store credentials for the various mechanisms, from the credential used for original authentication.
Q654. Sara, an attacker, is recording a person typing in their ID number into a keypad to gain access to the building. Sara then calls the helpdesk and informs them that their PIN no longer works and would like to change it. Which of the following attacks occurred LAST?
B. Shoulder surfing
Two attacks took place in this question. The first attack was shoulder surfing. This was the act of Sara recording a person typing in their ID number into a keypad to gain access to the building. The second attack was impersonation. Sara called the helpdesk and used the PIN to impersonate the person she recorded.
Q655. Which of the following components of an all-in-one security appliance would MOST likely be configured in order to restrict access to peer-to-peer file sharing websites?
A. Spam filter
B. URL filter
C. Content inspection
D. Malware inspection
Q656. What is the term for the process of luring someone in (usually done by an enforcement officer or a government agent)?
Enticement is the process of luring someone into your plan or trap.
Q657. A company is looking to improve their security posture by addressing risks uncovered by a recent penetration test. Which of the following risks is MOST likely to affect the business on a day-to-day basis?
A. Insufficient encryption methods
B. Large scale natural disasters
C. Corporate espionage
D. Lack of antivirus software
The most common threat to computers is computer viruses. A computer can become infected with a virus through day-to-day activities such as browsing web sites or emails. As browsing and opening emails are the most common activities performed by all users, computer viruses represent the most likely risk to a business.
Q658. Which of the following describes a type of malware which is difficult to reverse engineer in a virtual lab?
A. Armored virus
B. Polymorphic malware
C. Logic bomb
An armored virus is a type of virus that has been designed to thwart attempts by analysts from examining its code by using various methods to make tracing, disassembling and reverse engineering more difficult. An Armored Virus may also protect itself from antivirus programs, making it more difficult to trace. To do this, the Armored Virus attempts to trick the antivirus program into believing its location is somewhere other than where it really is on the system.
Q659. The datacenter design team is implementing a system, which requires all servers installed in racks to face in a predetermined direction. AN infrared camera will be used to verify that servers are properly racked. Which of the following datacenter elements is being designed?
A. Hot and cold aisles
B. Humidity control
C. HVAC system
D. EMI shielding
There are often multiple rows of servers located in racks in server rooms. The rows of servers are known as aisles, and they can be cooled as hot aisles and cold aisles. With a hot aisle, hot air outlets are used to cool the equipment, whereas with cold aisles, cold air intake is used to cool the equipment. Combining the two, you have cold air intake from below the aisle and hot air outtake above it, providing constant circulation. Infrared cameras are heat detection measures thus it is hot and cold aisle design elements.
Q660. Which of the following is the BEST way to prevent Cross-Site Request Forgery (XSRF) attacks?
A. Check the referrer field in the HTTP header
B. Disable Flash content
C. Use only cookies for authentication
D. Use only HTTPS URLs
XSRF or cross-site request forgery applies to web applications and is an attack that exploits the web applicationâs trust of a user who known or is supposed to have been authenticated. This is accomplished by changing values in the HTTP header and even in the userâs cookie to falsify access. It can be prevented by embedding additional authentication data into requests that allows the web application to detect requests from unauthorized locations. Examples are synchronizer token patterns, cookie-to-header tokens, and checking the HTTP Referrer header and the HTTP Origin header.
