Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Obtain business justification for each any-to-any rule

Overly permissive rules should be reviewed to determine if they are needed, and if so, should be tightened. If no business justification exists, they should be removed. If needed, they should be replaced with specific rules.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Obtain business justification for each any-to-any rule

    Why this is correct

    Understanding why the rule exists is the first step.

  • Replace any-to-any rules with specific source/destination rules

    Why this is correct

    Specific rules reduce the attack surface.

  • Immediately delete all any-to-any rules without review

    Why it's wrong here

    Deleting without review could disrupt business operations.

  • Increase logging for any-to-any rules to detect misuse

    Why it's wrong here

    Logging does not reduce risk; it only detects.

  • Remove any-to-any rules that lack business justification

    Why this is correct

    Unjustified rules should be eliminated.
