Scoring system (the same as at RuCTF 2009)

Categories of scoring:

  1. Attack

      • Team, submitting flag must have the corresponding service in UP state
      • First team to post +2, rest +1

  2. Defense

    • Confidentiality

      • Get list of not scored but too old (rotten) flags
      • Flag was not posted by another team -> +1

    • Integrity & Availability

      • check general functionality
      • put random flag f1
      • get the same flag f1
      • get some recent flag f2
      everything OK -> +1

Total team's score:

  1. Defense = Integrity & Availability + Confidentiality
  2. In all categories scores are percents from the leader's score
  3. Scores from all categories are summed
  4. Total score is again a percent from the leader's score
