This is a concern for me too! It's why I make a point of checking assets once a month. It means I get to notice if something's happened in time to act on it - and indeed I've found things like unauthorized charges. I've also discovered that small restaurants routinely charge my card an amount higher than I wrote on the receipt at the table. Or charged, since I no longer let those little f***rs have my credit card.
There's also the "inactive account" issue. It's good to systematically do something regularly that can be pointed to as "activity".
