I'm probably still not understanding well, but this seems pretty easy to model:

class SecurityTest
  def self.parse(scan_result_line)
    new(*scan_result_line.to_s.split)
  end
  
  def initialize(rule, result)
    @rule   = rule
    @result = result
  end
  
  attr_reader :rule
  
  def passed?
    @result == "pass"
  end
  
  def failed?
    @result == "fail"
  end
  
  def skipped?
    @result == "skipped"
  end
end

st = SecurityTest.parse("12.34 fail")
puts st.rule
p    st.failed?

Hope that helps.
