1. Which two statements describe access attacks? (Choose two.)
- Password attacks can be implemented by the use of brute-force attack methods, Trojan horses, or packet sniffers.
- Trust exploitation attacks often involve the use of a laptop to act as a rogue access point to capture and copy all network traffic in a public location, such as a wireless hotspot.

12. A security service company is conducting an audit in several risk areas within a major corporation. What statement describes the risk of access to removable media?
- the potential of causing great damage because of direct access to the building and its infrastructure devices
- intercepted emails that reveal confidential corporate or personal information
- the unauthorized transfer of data containing valuable corporate information to a USB drive
- data loss through access to personal or corporate instant messaging and social media sites
13. What is the purpose of a reconnaissance attack on a computer network?
- to gather information about the target network and system
- to redirect data traffic so that it can be monitored
- to prevent users from accessing network resources
- to steal data from the network servers
This item is based on information contained in the presentation.
Preventing users from accessing network resources is a denial of service attack. Being able to steal data from the network servers may be the objective after a reconnaissance attack gathers information about the target network and system. Redirecting data traffic so it can be monitored is a man-in-the middle attack.
14. A security service company is conducting an audit in several risk areas within a major corporation. What statement describes an internal threat?

- gaining illegal access to corporate data by stealing passwords or cracking weak passwords
