Which type of server is most likely to assist in recovering logs that were deleted by a privileged user?

A syslog server is designed to collect and store log data from different devices and applications in a centralized location. This centralization plays a crucial role in security monitoring and forensic analysis. When logs are deleted by a privileged user, the syslog server can still retain the log entries that were sent to it before deletion occurred.

This retention of logs allows security professionals to maintain a complete record of events that can be reviewed for compliance, audit, or investigative purposes. By utilizing a syslog server, organizations can ensure they have access to crucial log data even if local logs on individual systems are compromised or deleted.

In contrast, memory dumps are temporary and volatile and usually contain real-time data rather than historical log data. Application logs are specific to the individual application and may be subject to deletion by a privileged user. Log retention policies dictate how logs are stored and for how long but do not directly assist in recovering deleted logs. Thus, the syslog server is the most reliable option for recovering logs in the event of deletion.
