I've added security to two questions tagged anti-cheat, then I realized there is no clear question which addresses "anti-cheat" without being also more in general related to "security".
I'd like us to either produce some guidelines about when to use these tags, or to remove anti-cheat altogether if it is a duplicate or a subset of security.
In my opinion anti-cheat is a subset of security - in the same way that, say, xna is a subset of game-development. Using hyperbole: if we removed subset tags we would ultimately land up with exactly one tag (game-development). Security could further be broken down into things such as: authentication, in-game-purchases, encryption, privacy and, yes, anti-cheat - all of these help an answerer discriminate between questions where her expertise might lie. So I would say: update the wiki of security to include other tags like anti-cheat.
