  • When Should We Use Extra Detection Rules?
    • “Rule one strikes a balance between the consequences of either getting a false alarm or missing a signal of economic importance. Using additional detection rules shifts this balance.

Additional detection rules should very definitely not be used just because the software allows you to do so.”
