A new security engineer has started hardening systems. One of the hardening techniques the engineer is using involves disabling remote logins to the NAS. Users are now reporting the inability to use SCP to transfer files to the NAS, even though the data is still viewable from the users' PCs. Which of the following is the MOST likely cause of this issue?
Correct Answer:B
Disabling remote logins to the NAS likely involved turning off SSH instead of modifying the configuration file. This would prevent users from using SCP to transfer files to the NAS, even though the data is still viewable from the users' PCs. Source: TechTarget

A company wants to modify its current backup strategy to modify its current backup strategy to minimize the number of backups that would need to be restored in case of data loss. Which of the following would be the BEST backup strategy
Correct Answer:B
The best backup strategy for minimizing the number of backups that need to be restored in case of data loss is full backups followed by incremental backups. This strategy allows for a complete restoration of data by restoring the most recent full backup followed by the most recent incremental backup.

Which of the following cloud models provides clients with servers, storage, and networks but nothing else?
Correct Answer:C
laaS (Infrastructure as a Service) is a cloud model that provides clients with servers, storage, and networks but nothing else. It allows clients to have more control and flexibility over the configuration and management of their infrastructure resources, but also requires them to install and maintain their own operating systems, applications, etc.

Which of the following best describes configuring devices to log to a centralized, off-site location for possible future reference?
Correct Answer:C
Archiving is the process of storing data for long-term preservation. In the context of IT security, archiving logs is the process of collecting and storing log files from devices in a centralized location. This allows organizations to access and analyze log data for troubleshooting, compliance, and security auditing purposes.
Log aggregation is the process of collecting log data from multiple sources and storing it in a single location. This can be done for performance or security reasons. However, log aggregation does not necessarily involve storing the logs in an off-site location.
DLP (Data Loss Prevention) is a set of technologies and processes that are used to protect sensitive data from unauthorized access, use, disclosure, alteration, or destruction. DLP can be used to prevent data from being exfiltrated from an organization's network, but it does not typically involve storing logs in an off-site location.
SCAP (Security Content Automation Protocol) is a set of standards and tools that are used to automate the assessment and remediation of security vulnerabilities. SCAP can be used to collect log data from devices, but it does not typically involve storing the logs in an off-site location.
Therefore, the best answer to the question is archiving.

Which of the following authentication methods sends out a unique password to be used within a specific number of seconds?
Correct Answer:A
Time-based One-Time Password (TOTP) is a type of authentication method that sends out a unique password to be used within a specific number of seconds. It uses a combination of a shared secret key and the current time to generate a one-time password. TOTP is commonly used for two-factor authentication (2FA) to provide an additional layer of security beyond just a username and password.
