The Stronghold of Security is one of the first free to play releases by Jagex since RuneScape II. It is a fairly simple game, with interesting rewards. The rewards include new emoticons, a bit of money, and unlocking new training areas with a few new monsters. Each level of the dungeon changes in degree of difficulty as you go lower - this is noticed in the monster's levels; not the questions.
Before setting out to play this mini game, you should prepare yourself. Bring some form of armour and weapon, as well as a little bit of food if you plan to go all the way through the dungeon. When you believe you're ready, head to the middle of Barbarian Village, by the coal and tin mine.
Here you will find Litara, whose brother, an explorer, disappeared down in the dank, dark dungeon some time ago. She will ask you to keep your eyes open for him. Unfortunately, when you enter the dungeon after climbing down the entrance hole, you find the explorer's skeleton rotting away by the first Gates of War. Search the skeleton to find her brother's notes on the Stronghold of Security.
The objective of this mini game is to simply learn more about what you should be doing to make sure your account is secure, and remains secure. http://www.igegolds.com
It also serves as a good place to train for f2p
