Implementing input validations will prevent code injection attacks by verifying the type and format of user input. Reference: CompTIA Security+ Study Guide: Exam SY0-601, Chapter 8

Explanation
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.
