Which of the following would prevent unauthorized changes to information stored in a servers log?

A. Write-protecting the directory containing the system log

B. Writing a duplicate log to another server

C. Daily printing of the system log

D. Storing the system log in write-once media

Explanation:

Storing the system log in write-once media ensures the log cannot be modified. Write- protecting the system log does not prevent deletion or modification, since the superuser or users that have special permission can override the write protection. Writing a duplicate log to another server or daily printing of the system log cannot prevent unauthorized changes.
