Temporary files

  1. Should be placed securely in a folder called “temp” in the web root

  2. Can be placed anywhere in the web root as long as there are no links to them

  3. Should be completely removed from the server

  4. Can be placed anywhere after changing the extension
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Temporary files often contain sensitive operational data and should be completely removed from the server to prevent info leakage. Leaving them in public folders like the web root, even without links or with modified extensions, exposes them to discovery by attackers utilizing directory brute-forcing or source disclosure exploits.

What is the preferred medium for backing up log files ?

  1. Print the logs to a paper

  2. Create a copy of data in your laptop/desktop

  3. Copy the files to CD-R's

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Copying log files to CD-Rs or other Write-Once-Read-Many (WORM) media is the preferred backup method because it prevents logs from being altered or deleted by attackers trying to hide their tracks. Printing on paper or copying to easily mutable local laptop drives does not offer the same security guarantees.
