CompTIA Security+ Question G-69

The security manager received a report that an employee was involved in illegal activity and has saved data to a workstation’s hard drive. During the investigation, local law enforcement’s criminal division confiscates the hard drive as evidence. Which of the following forensic procedures is involved?

A. Chain of custody
B. System image
C. Take hashes
D. Order of volatility

Answer: A

Explanation:
Chain of custody deals with how evidence is secured, where it is stored, and who has access to it. When you begin to collect evidence, you must keep track of that evidence at all times and show who has it, who has seen it, and where it has been.

CompTIA Security+ Question G-68

An administrator needs to connect a router in one building to a router in another using Ethernet. Each router is connected to a managed switch and the switches are connected to each other via a fiber line. Which of the following should be configured to prevent unauthorized devices from connecting to the network?

A. Configure each port on the switches to use the same VLAN other than the default one
B. Enable VTP on both switches and set to the same domain
C. Configure only one of the routers to run DHCP services
D. Implement port security on the switches

Answer: D

Explanation:
Port security in IT can mean several things: The physical control of all connection points, such as RJ-45 wall jacks or device ports, so that no unauthorized users or unauthorized devices can attempt to connect into an open port. The management of TCP and User Datagram Protocol (UDP) ports. If a service is active and assigned to a port, then that port is open. All the other 65,535 ports (of TCP or UDP) are closed if a service isn’t actively using them. Port knocking is a security system in which all ports on a system appear closed. However, if the client sends packets to a specific set of ports in a certain order, a bit like a secret knock, then the desired service port becomes open and allows the client software to connect to the service.

CompTIA Security+ Question G-67

Computer evidence at a crime is preserved by making an exact copy of the hard disk. Which of the following does this illustrate?

A. Taking screenshots
B. System image capture
C. Chain of custody
D. Order of volatility

Answer: B

Explanation:
A system image would be a snapshot of what exists at the moment. Thus capturing an image of the operating system in its exploited state can be helpful in revisiting the issue after the fact to learn more about it.

CompTIA Security+ Question G-66

A financial company requires a new private network link with a business partner to cater for realtime and batched data flows.
Which of the following activities should be performed by the IT security staff member prior to establishing the link?

A. Baseline reporting
B. Design review
C. Code review
D. SLA reporting

Answer: B

Explanation:
This question is asking about a new private network link (a VPN) with a business partner. This will provide access to the local network from the business partner. When implementing a VPN, an important step is the design of the VPN. The VPN should be designed to ensure that the security of the network and local systems is not compromised. The design review assessment examines the ports and protocols used, the rules, segmentation, and access control in the systems or applications. A design review is basically a check to ensure that the design of the system meets the security requirements.

B. Employ exact data matching and prevent inbound emails with Data Loss Prevention.
C. Employ hashing on all outbound emails containing confidential information.
D. Employ exact data matching and encrypt inbound e-mails with Data Loss Prevention.

Answer: A

Explanation:
Encryption is used to ensure the confidentiality of information and in this case the outbound email that contains the confidential information should be encrypted.

CompTIA Security+ Question G-63

A security administrator forgets their card to access the server room. The administrator asks a coworker if they could use their card for the day. Which of the following is the administrator using to gain access to the server room?

A. Man-in-the-middle
B. Tailgating
C. Impersonation
D. Spoofing

Answer: C

Explanation:
Impersonation is where a person, computer, software application or service pretends to be someone or something it’s not. Impersonation is commonly non-maliciously used in client/server applications. However, it can also be used as a security threat.

In this question, by using the coworker’s card, the security administrator is ‘impersonating’ the coworker. The server room locking system and any logging systems will ‘think’ that the coworker has entered the server room.

CompTIA Security+ Question G-62

Jane, a security analyst, is reviewing logs from hosts across the Internet which her company uses to gather data on new malware. Which of the following is being implemented by Jane’s company?

A. Vulnerability scanner
B. Honeynet
C. Protocol analyzer
D. Port scanner

Answer: B

Explanation:
The Internet hosts used to gather data on new malware are known as honeypots. A collection of honeypots is known as a honeynet. A honeynet is a network set up with intentional vulnerabilities; its purpose is to invite attack, so that an attacker’s activities and methods can be studied and that information used to increase network security. A honeynet contains one or more honey pots, which are computer systems on the Internet expressly set up to attract and “trap” people who attempt to penetrate other people’s computer systems. Although the primary purpose of a honeynet is to gather information about attackers’ methods and motives, the decoy network can benefit its operator in other ways, for example by diverting attackers from a real network and its resources. The Honeynet Project, a non-profit research organization dedicated to computer security and information sharing, actively promotes the deployment of honeynets. In addition to the honey pots, a honeynet usually has real applications and services so that it seems like a normal network and a worthwhile target. However, because the honeynet doesn’t actually serve any authorized users, any attempt to contact the network from without is likely an illicit attempt to breach its security, and any outbound activity is likely evidence that a system has been compromised. For this reason, the suspect information is much more apparent than it would be in an actual network, where it would have to be found amidst all the legitimate network data. Applications within a honeynet are often given names such as “Finances” or “Human Services” to make them sound appealing to the attacker.

A virtual honeynet is one that, while appearing to be an entire network, resides on a single server.

CompTIA Security+ Question G-61

A quality assurance analyst is reviewing a new software product for security, and has complete access to the code and data structures used by the developers. This is an example of which of the following types of testing?

A. Black box
B. Penetration
C. Gray box
D. White box

Answer: D

Explanation:
White box testing is the process of testing an application when you have detailed knowledge of the inner workings of the application. White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing). In white-box testing an internal perspective of the system, as well as programming skills, are used to design test cases. The tester chooses inputs to exercise paths through the code and determine the appropriate outputs. This is analogous to testing nodes in a circuit, e.g. in-circuit testing (ICT). White-box testing can be applied at the unit, integration and system levels of the software testing process. Although traditional testers tended to think of white-box testing as being done at the unit level, it is used for integration and system testing more frequently today. It can test paths within a unit, paths between units during integration, and between subsystems during a system–level test.
