Explanation
The MOST serious consequence of mobile device loss or theft is the compromise of transient data. Transient data is data that is temporarily stored or processed on a mobile device, such as cached data, cookies, browsing history, passwords, or session tokens. Transient data can reveal sensitive information about the user or the organization and can be exploited by attackers to gain access to other systems or networks.

Using a data loss prevention (DLP) solution to monitor data saved to a USB memory device is an example of managing data at rest. Data at rest is data that is stored on a device or media, such as hard disks, flash drives, tapes, or CDs. Data at rest can be exposed to unauthorized access, theft, or loss if not properly protected. A DLP solution is a tool that monitors and controls the movement and usage of data across an organization's network or endpoints. A DLP solution can prevent users from saving sensitive data to removable devices or alert on any violations of data policies.

In a teaming exercise, the purple team is responsible for integrating the defensive tactics and controls from the blue team (defensive) with the threats and vulnerabilities found by the red team (attacking). The purple team's role is to ensure that the defense mechanisms are effective against the identified threats and to improve the overall security posture of the organization. They work collaboratively with both the red and blue teams to provide a comprehensive view of the organization's security readiness1.

Security awareness training is MOST effective against social engineering threats. This is because social engineering is a type of attack that exploits human psychology and behavior to manipulate or trick users into revealing sensitive or confidential information, or performing actions that compromise security. Security awareness training helps to educate users about the common types and techniques of social engineering attacks, such as phishing, vishing, baiting, etc., and how to recognize and avoid them. Security awareness training also helps to foster a culture of security within the organization and empower users to report any suspicious or malicious activities. The other options are not types of threats that security awareness training is most effective against, but rather types of attacks that exploit technical vulnerabilities or flaws in systems or applications, such as command injection (A), denial of service (B), or SQL injection (D).

The intrusion detection system component that is responsible for collecting data in the form of network packets, log files, or system call traces is sensors. This is because sensors are components of an intrusion detection system that are deployed on various locations or points of the network or system, such as routers, switches, servers, etc., and that capture and collect data from the network traffic or system activities. Sensors then forward the collected data to another component of the intrusion detection system, such as analyzers, for further processing and analysis. The other options are not components of an intrusion detection system that are responsible for collecting data in the form of network packets, log files, or system call traces, but rather different components or techniques that are related to intrusion detection or prevention, such as packet filters (A), analyzers (B), or administration modules C.
